Gap closure ledger
Blocker/high gaps are closed in-page; unresolved items remain explicitly marked for follow-up.
| Gap found | Decision impact | Stage1b action | Status |
|---|---|---|---|
| UN38.3 wording was too broad and did not show the HM-215Q exception for button cells installed in equipment. | High risk of incorrect shipment-go/no-go decisions and unnecessary blockers in early RFQ planning. | Added PHMSA July-2024 scope boundary: exception applies to button cells installed in equipment; TS must be made available on request for applicable batteries. | Closed in stage1b deep-enhance round (2026-04-28) |
| Page did not show a concrete cross-supplier electrical counterexample for same 10mm class parts. | High risk of diameter-only substitution ("10mm = interchangeable") causing startup/rail mismatches. | Added Jinlong C1030Q002F vs PMD 310-103.004 counterexample across operating voltage, rated current, and startup boundaries. | Closed in stage1b deep-enhance round (2026-04-28) |
| `10pcs vibration motor` intent lacked lot-traceability and pilot-to-volume risk framing. | High risk of treating a small pilot order as production-quality evidence without sampling/traceability controls. | Added PMD traceability and ISO 2859 sampling context, plus explicit 10pcs pilot scenario actions. | Closed in stage1b deep-enhance round (2026-04-28) |
| Lifetime references were easy to overread as guaranteed field life. | High risk of overpromising reliability based on supplier "typical" rows without product-level validation. | Added explicit MTTF boundary and "design-guidance-only" interpretation to conclusions and risk logic. | Closed in stage1b deep-enhance round (2026-04-28) |
| `10pcs vibration motor` alias intent was missing from intro, FAQ routing checks, and canonical anchor chips. | High risk that quantity-pack buyers interpret this as a separate route need and miss canonical tool execution. | Added explicit `10pcs vibration motor` wording to heading context, metadata-aligned intro, alias anchors, and routing FAQ answers on `/learn/vibration-motor`. | Closed in stage1c alias merge round (2026-04-28) |
| `10mm coin vibration motor 3v datasheet` alias intent was not explicitly visible in heading/anchor/FAQ coverage. | High risk of intent miss: users seeking PN-style 3V datasheet boundaries may assume this URL is unrelated. | Added explicit alias wording in hero, metadata-aligned copy, alias anchor cards, and FAQ routing answers. | Closed in stage1b deep-enhance round (2026-04-24) |
| Some ERM/LRA response and electrical details were stale or transcribed without latest datasheet recheck. | High risk of wrong architecture tradeoff, especially around stop-time expectation and 3V boundary interpretation. | Revalidated PMD 310-103 and C10-100 datasheets; corrected response/electrical facts and rewrote tradeoff notes with scope conditions. | Closed in stage1b deep-enhance round (2026-04-24) |
| Battery section used only low-current baseline wording without an explicit pulse-load counterexample. | High risk of misreading 3V coin-cell naming as sufficient for motor startup bursts. | Added Energizer CR2032 pulse profile evidence and tied it to startup-current boundary actions. | Closed in stage1b deep-enhance round (2026-04-24) |
| Shipping requirement note leaned on secondary summary wording. | Medium-to-high risk of documentation misses in pilot logistics execution. | Added PHMSA primary guidance row with publication/effective dates for UN38.3 test-summary requirement. | Closed in stage1b deep-enhance round (2026-04-24) |
| Core conclusions cited only marketing listing values, without PN-level datasheet limits and test conditions. | High risk of treating class-level examples as hard qualification limits. | Added PN-level ERM/LRA datasheet boundaries (start voltage/current, max operating voltage, response timings, test-load context). | Closed in stage1b enhancement (2026-04-20) |
| Comparison section lacked concrete counterexample triggers for ERM-to-LRA migration. | High risk of selecting architecture by intuition instead of boundary data. | Added boundary trigger matrix with explicit limit, source, and minimum corrective action. | Closed in stage1b enhancement (2026-04-20) |
| Regulatory and shipping requirements for coin-cell consumer products were not represented in decision flow. | High risk of late-stage compliance rework or shipment blocking. | Added CPSC 16 CFR 1263 / UL 4200A and UN38.3 test-summary gates in risk+FAQ guidance. | Closed in stage1b enhancement (2026-04-20) |
| `10 mm disc vibration motor`, `10pcs vibration motor`, `1027 vibration motor`, and `10mm coin vibration motor 3v datasheet` alias intent were not explicitly answered together on a canonical hybrid page. | High risk of duplicate routes and split keyword signals. | Built one canonical hybrid page at `/learn/vibration-motor` with multi-alias anchors and FAQ coverage. | Closed in stage1b baseline + alias extensions (2026-04-24) |
| Tool guidance lacked numeric boundaries for voltage, rpm, amplitude, and duty. | High risk of using out-of-range requests as procurement-ready outputs. | Added strict input ranges, boundary state messaging, and alternate CTA paths. | Closed in stage1b baseline (2026-04-20) |
| Report layer had no reproducible ERM vs LRA decision table for 10mm disc use cases. | High risk of wrong actuator family selection during RFQ pre-screening. | Added comparison matrix with frequency/amplitude/driver-complexity/cost dimensions. | Closed in stage1b baseline (2026-04-20) |
| Battery suitability discussion ignored coin-cell current-class mismatch against motor start current. | Medium-to-high risk of false starts and brownout loops in compact designs. | Added explicit CR2032 baseline vs high-drain class notes and mitigation actions. | Closed in stage1b baseline (2026-04-20) |

- Need explicit next action when result is conditional or boundary-failing.
Who this is not suitable for
- Safety-critical haptics that require certified reliability qualification data.

Methods and evidence
Transparent formulas, dated sources, and explicit known/unknown boundaries.
Method flow
Input to estimate to boundary check to action path.
| Method block | Formula / rule | Decision value |
|---|---|---|
| Frequency conversion | f(Hz) = rpm / 60 | Converts motor-speed input to vibration frequency for haptic target mapping. |
| Estimated RMS vibration | G_est ~= (rpm / 12200) * (V / 3.0) * env_factor | Uses a 10mm ERM reference point; output is screening-grade, not qualification-grade. |
| Operating current estimate | I_run ~= base + speed/load/duty penalties | Models current envelope needed for pre-RFQ power-path screening. |
| Startup current estimate | I_start ~= 1.9 * I_run (conservative screen) | Uses margin above one cited 10mm ERM ratio (~150mA/90mA ~= 1.67) to reduce false-safe screening outcomes. |
| Confidence score | Base 92 - boundary penalties | Penalizes high duty, high amplitude, and rail mismatch conditions. |

New evidence-backed decision facts
Update date: 2026-04-28. Facts without stable public evidence stay in the pending block.
| Topic | New fact | Applicable condition | Decision effect | Certainty |
|---|---|---|---|---|
| `3V datasheet` label boundary | For the cited 10mm ERM PN, `3V` is a rated point, while the same datasheet also publishes 2.3V max start and 3.6V max operating limits. | Applies to that PN and listed inertial-load setup; cross-vendor 10mm parts can differ. | Do not treat `3V` wording as blanket overvoltage approval; requests above 3.6V move to boundary review/fallback. | Known with PN scope |
| 10mm cross-supplier electrical counterexample | Jinlong C1030Q002F (10mm class) is rated 2.0V with 1.7V-2.3V operating range and 70mA rated current max, while PMD 310-103.004 is rated 3.0V with 3.6V max operating and 90mA rated current max. | Both are 10mm coin ERM references, but they are different part numbers and vendor test setups. | Do not substitute by diameter or alias wording (`1027`/`10mm`) alone; compare PN-level electrical rows before RFQ lock. | Known with cross-vendor PN scope |
| 10mm ERM electrical + timing envelope | The cited ERM datasheet lists lag/rise/stop around 40ms / 87ms / 115ms (typical), plus 61Ohm typical resistance and 349uH typical inductance. | Frequency depends on actual drive voltage and load coupling. | Use as screening envelope only; if release feel depends on stop behavior, include waveform-level brake validation before RFQ freeze. | Known with test-condition scope |
| 10mm LRA measurable counterexample | C10-100 datasheet lists 2Vrms @ 175Hz and 0.5Vrms max start with lag/rise around 11ms / 37ms, but stop around 177ms without active-brake behavior. | LRA behavior depends on resonance tracking and frequency control near the PN resonance. | When chasing crisp onset and release, do not assume LRA is automatically better on every axis; run ERM/LRA A/B with actual drive mode. | Known with PN scope |
| Driver architecture boundary | DRV2605L supports ERM/LRA haptic control with 125-300Hz LRA frequency support, while DRV8837 is a generic H-bridge (VM 0-11V, VCC 1.8-7V). | A wide VM range does not imply haptic waveform quality or resonance control equivalence. | Keep DRV2605L-class path for nuanced haptics; reserve DRV8837-class path for simpler brushed-drive envelopes. | Known with architectural scope |
| Coin-cell chemistry boundary | Panasonic and Energizer datasheets publish low continuous-drain classes (for example 0.2mA or 190uA), while Energizer pulse examples are still around 10mA-class, below many ERM startup bursts. | Capacity and baseline drain numbers are not direct pulse-current guarantees. | Coin-cell-only direct-drive is treated as conditional/not-fit unless power path is redesigned. | Known with chemistry and test-condition scope |
| Regulatory and logistics gate | CPSC guidance and eCFR show U.S. product-safety gates (16 CFR 1263 + UL 4200A-2023), while PHMSA shows UN38.3 test-summary logistics rules with explicit scope boundaries. | Applies to covered consumer products and applicable battery-shipping channels; some categories are exempted by rule text. | Split product-compliance checks from shipment-document checks, and run explicit scope screening before blocking a project path. | Known with jurisdiction and logistics scope |
| UN38.3 test-summary scope boundary | PHMSA guide states test-summary requirement applies to lithium cells/batteries (including those in products), except button cells installed in equipment, and summaries are provided on request rather than mandatory in every shipment carton. | US DOT harmonization context; still requires battery-family applicability and document ownership mapping. | Treat missing TS as a blocker for applicable battery shipments, but do not over-apply this blocker to excepted installed button-cell cases. | Known with logistics scope |
| 10pcs pilot procurement boundary | PMD datasheets state life values are design guidance only and emphasize batch traceability and agreed sampling plans (e.g., ISO 2859 references in supplier documentation). | Supplier-specific documentation; not a universal cross-vendor qualification substitute. | Do not use a 10pcs pilot as production reliability proof; require lot traceability and acceptance sampling terms before volume commitment. | Known with supplier-scope boundary |
| Standards baseline update | IEC publication metadata shows IEC 60086-4:2025 (published 2025-01-29) replacing the prior edition and listing technical changes including revised child-resistant packaging references. | Standard applicability depends on your product market and conformity pathway. | Treat IEC edition references as time-sensitive and confirm target-market version before compliance freeze. | Known with standards scope |
Pending confirmation / no reliable public data
Evidence is insufficient for strong conclusions in these areas.
| Open question | Why evidence is insufficient | Decision impact |
|---|---|---|
| Long-cycle amplitude retention for 10mm discs bonded to real production housings. | Public datasets rarely include enclosure-coupled adhesive aging under matched duty cycles. | Cannot issue hard lifetime claims for amplitude drift without PN-level validation. |
| Cross-vendor acoustic spectra measured on identical fixture and mounting geometry. | Most public measurements are generated on different test rigs and filtering methods. | Noise comparisons remain directional; procurement decisions require your own bench data. |
| Battery aging impact on startup reliability for compact high-current bursts. | Open datasets do not normalize chemistry/temperature/state-of-health consistently. | Brownout and start-failure risk remains conditional until pack-level waveform capture. |
| Cross-vendor 10mm ERM-vs-LRA lifetime comparison on one unified fixture. | Public PN datasheets use different fixtures, waveforms, and duty assumptions, which blocks fair direct life ranking. | Architecture choice should use in-house A/B validation instead of a single normalized life claim. |
| Public pass/fail threshold linking 10pcs pilot lots to mass-production Cp/Cpk outcomes. | No reliable open dataset maps tiny pilot sample outcomes to statistically defensible production process capability for vibration motors. | Pilot success should be treated as feasibility evidence only, not as final incoming-quality assurance. |
| Unified public datasheet registry for `10mm coin vibration motor 3v datasheet` alias queries. | No authoritative open repository normalizes PN-level 10mm coin motor electrical and durability fields across suppliers. | Procurement teams still need supplier-by-supplier datasheet intake and normalization before final comparison. |
Alternative comparison
Use reproducible dimensions (voltage, amplitude, response, cost, fit) instead of generic claims.
Option comparison table
If a value is unavailable in your project context, keep it as N/A and request supplier evidence.
| Option | Voltage band | Torque band | Dynamic response | Cost class | Best-fit scenario | Boundary / counterexample |
|---|---|---|---|---|---|---|
| 10mm disc ERM (brushed) | 3.0V rated, 3.6V max op, 2.3V max start | 1.3G typ / 0.75G min (datasheet test load) | Lag 40ms, rise 87ms, stop 115ms (typical) | Low | General alerts and haptic cues in compact products. | 90mA rated max and 150mA start max constrain battery path; cited MTTF is test-condition specific. |
| 10mm disc ERM (2V-class counterexample PN) | 2.0V rated, 1.7V to 2.3V operating (C1030Q002F) | N/A (public cross-rig normalization unavailable) | Rise time 170ms max (datasheet row) | Low to medium | Low-voltage rails that cannot sustain 3V-class operation windows. | Same 10mm diameter does not imply same electrical boundaries; treat as PN-level branch, not direct swap. |
| 10mm LRA coin actuator | 2.0Vrms rated, 2.05Vrms max, 0.5Vrms max start | 1.5G typ / 1.0G min (datasheet test load) | Lag 11ms, rise 37ms, stop 177ms (typical) | Medium | Premium haptic profiles needing tighter effect consistency. | Requires resonance-aware drive; onset can be fast but release can be slower without an actively tuned control strategy. |
| 12mm ERM disc | N/A (PN dependent; request supplier datasheet) | N/A (public fixture-normalized data unavailable) | Varies by PN and mounting stack | Low to medium | Higher-mass products where 10mm force margin is insufficient. | Larger diameter may break packaging constraints or raise audible output; no single public normalized baseline. |
| Dual 10mm ERM layout | N/A (architecture-specific rail design) | N/A (depends on phasing and fixture) | Pattern flexibility with control complexity | Medium | Products needing multiple haptic zones or stronger burst effects. | Current peaks, thermal load, and synchronization complexity increase substantially. |
Boundary trigger matrix
Each trigger includes a source-tied reason and a minimum executable action.
| Trigger condition | Why it matters | Source anchor | Minimum action |
|---|---|---|---|
| Interpreting `3V datasheet` label as safe for direct 4.2V battery drive | The cited ERM PN is rated 3.0V and publishes 3.6V max operating voltage. | PMD 310-103.004 datasheet | Treat as overvoltage boundary: add regulation/driver derating or select a different qualified PN. |
| Input voltage > 3.6V for baseline 10mm ERM path | Cited ERM PN max operating voltage is 3.6V. | PMD 310-103.004 datasheet | Switch to high-voltage-qualified actuator/driver path or reduce rail before sample selection. |
| Input voltage < 2.3V for baseline 10mm ERM path | Cited ERM PN max start voltage is 2.3V with inertial load. | PMD 310-103.004 datasheet | Treat as startup-risk boundary; redesign power path or choose actuator with lower start threshold. |
| Selecting a replacement only by `10mm` / `1027` naming | C1030Q002F and 310-103.004 show same-class geometry with different rated/operating voltage windows and current rows. | C1030Q002F + PMD 310-103.004 datasheets | Block dimension-only substitution; compare PN-level electrical rows before approving equivalent sourcing. |
| Predicted startup current exceeds battery burst capability | Coin-cell datasheets show low continuous classes and modest pulse examples versus motor startup bursts. | Panasonic + Energizer CR2032 datasheets | Add reservoir/boost or move to battery architecture that can support startup transients. |
| Need both fast onset and fast stop in the same haptic profile | Cited LRA lag/rise is faster, but cited LRA stop time is longer than cited ERM stop time under listed conditions. | PMD C10-100 vs 310-103 datasheets | Run ERM/LRA A/B prototype with actual drive mode and braking strategy; do not choose by one timing metric. |
| US consumer product uses replaceable coin battery access path | CPSC guidance cites 16 CFR 1263 + UL 4200A-2023 expectations for covered products. | CPSC guidance and final rule notice | Run compliance gate review before RFQ freeze to prevent redesign at launch stage. |
| Battery-powered SKU enters pilot shipping without test-summary package | PHMSA guidance requires UN38.3 summaries for applicable lithium cells/batteries and also states installed button cells in equipment are excepted. | PHMSA UN38.3 test-summary update | Check applicability first, then collect test-summary files and owner responsibility mapping before pilot logistics release. |
| Using a 10pcs pilot lot as final production reliability evidence | Supplier docs frame life rows as design guidance and call for lot traceability plus agreed sampling plans. | PMD 310-103.004 and C10-100 datasheets | Require traceability fields and acceptance-sampling definition before volume PO approval. |
Risk and mitigation
Covers misuse risk, cost risk, and scenario mismatch risk with direct mitigation actions.
Risk matrix
| Risk | Impact | Probability | Mitigation path |

| Treating `3V` naming as universal max-voltage approval | High | Medium | Use PN-level voltage rows (rated/start/max op) and enforce overvoltage gating in early architecture review. |
| Drive voltage below practical startup region for 10mm ERM | High | Medium to high | Treat <2.3V as boundary state; redesign rail or actuator class before sourcing. |
| Assuming all 10mm / 1027 parts are electrically interchangeable | High | Medium to high | Use PN-level comparison (rated/operating voltage, startup current, timing), not diameter-only equivalence. |
| Battery path cannot supply startup-current burst | High | High in coin-cell-only designs | Validate startup pulse on real pack; add reservoir/boost or change battery architecture. |
| Assuming generic H-bridge equals haptic driver capability | High | Medium | Separate motor-drive feasibility from haptic quality requirements; keep ERM/LRA control-fit review before driver freeze. |
| Assuming LRA always stops faster because onset is faster | Medium to high | Medium | Use complete timing rows (lag/rise/stop) and verify with selected drive mode before architecture lock. |
| Target G set above realistic 10mm disc envelope | High | Medium | Shift to larger ERM, dual-motor layout, or LRA architecture as required. |
| High duty cycle causes thermal drift and amplitude drop | High | Medium | Apply duty derating, ramp profile, and thermal validation before release. |
| Mounting adhesive and enclosure coupling mismatch | Medium | Medium | Validate on final enclosure stack, not only free-air bench fixtures. |
| US coin-cell compliance gate discovered too late | High | Medium | When shipping to U.S. consumer channels, review 16 CFR 1263 and UL 4200A requirements during architecture phase, not at launch. |
| Missing UN38.3-aligned test-summary evidence for battery logistics | Medium to high | Medium | Run applicability screening first (including installed button-cell exceptions), then collect test-summary evidence for applicable battery shipments. |
| Treating 10pcs pilot success as proof of mass-production reliability | High | Medium | Hold volume-release decisions until traceability fields, sampling plans, and incoming-quality criteria are contractually defined. |
| Driver family selected without ERM/LRA control-fit check | Medium | Medium | Confirm actuator type, control mode, and supply envelope together in architecture review. |
| Alias intent interpreted as standalone route | Medium | Medium | Keep one canonical page and expose alias anchors across tool and FAQ sections. |
Scenario examples
Each scenario includes assumptions, modeled output, and the minimum next action.
Scenario table
| Scenario | Assumption | Estimated result | Action |
|---|---|---|---|
| Smartwatch alert module | 3.0V rail, 12,200 rpm target, 1.0G, 25% duty | Recommended with standard 10mm disc ERM class. | Request two PN samples and validate startup feel plus enclosure-coupled amplitude. |
| Coin-cell direct-drive prototype | CR2032-only rail, 12,000 rpm target, 1.1G, 30% duty | Conditional to not recommended depending pulse path. | Capture startup waveform and brownout behavior before selecting production BOM. |
| High-force handheld notification | 3.7V rail, 13,500 rpm target, 2.0G, 65% duty | Boundary review needed for 10mm disc class. | Evaluate 12mm ERM or LRA/dual-motor fallback architecture. |
| High-temperature enclosure | 3.0V rail, 12,000 rpm target, 1.2G, 50% duty, high ambient | Conditional due to thermal and adhesive risk. | Apply duty derating and run enclosure thermal validation. |
| Low-noise medical handheld | 3.3V rail, 10,500 rpm target, 0.8G, 35% duty, noise priority | Conditional with actuator-family comparison. | Run ERM vs LRA A/B test and choose based on measured acoustic profile. |
| US consumer wearable with replaceable coin cell | Coin-cell-powered alert product targeting U.S. consumer channels | Conditional pending compliance and transport evidence. | Run 16 CFR 1263 / UL 4200A check, then perform UN38.3 applicability screening (including installed button-cell exception) before RFQ lock. |
| 10pcs pilot order before supplier shortlist freeze | Small pilot quantity is available quickly, but no lot-traceability packet or sampling plan is defined yet. | Conditional and not production-ready. | Use pilot for feasibility only; request traceability fields, acceptance sampling terms, and volume-lot consistency data before production PO. |
