The audit executor has finished. I’m reconciling its findings against the actual project state and will close out any remaining verification or reporting gaps.

Audit complete. The existing Datasheet property already links to the official Eaton PDF, so no update was necessary; pin count, polarity, 3.5 mm pitch, and 8 mm body diameter match.

Key flags: unverified 3D-model seating, missing structured Manufacturer property, misleading TO package classification, generic rectangular symbol, and absent pin descriptions. Full results: Part Quality Audit.

Part Quality Audit

Scope and authority

Audited the published Flux part project for Eaton HSL0814-3R8106-R against Eaton’s official HS/HSL Supercapacitors — Hybrid cylindrical cells, Technical Data 11043 (effective February 2025):

Official PDF: https://www.eaton.com/content/dam/eaton/products/electronic-components/resources/data-sheet/eaton-supercapacitor-hybrid-cylindrical-cells-data-sheet.pdf
Exact identity evidence: Eaton’s electrical and dimensional tables list HS/HSL0814-3R8106-R; the packaging table lists the standalone HSL0814-3R8106-R variant.

The current Datasheet URL already points to this stable official Eaton PDF, so no property edit was made.

Eaton does not publish a recommended PCB land pattern, finished-hole diameter, or copper-pad diameter in this datasheet. Therefore hole and land suitability cannot be called an official match; only their relationship to the published lead diameter can be evaluated.

Schematic symbol and terminal audit

Current symbol

Custom symbol body: plain 220 × 220 rectangular box.
Two terminals, no nets.
Pin 1: name/designator +, passive type, left side.
Pin 2: name/designator −, passive type, right side.
Both terminal objects have Part Type Terminal, Pin Type Passive, and pin numbers 1/2.
Pin Description is absent for both terminals.

Comparison

Confirmed match: two electrical terminals; polarized + and − representation; passive pin type is appropriate; pin 1 is consistently bound to the footprint’s positive-marked rectangular pad, and pin 2 to the circular negative pad.
Not specified by Eaton: Eaton labels physical terminals + and − but does not assign schematic/PCB numbers 1 and 2. The project’s 1 = +, 2 = − convention is internally consistent but not manufacturer-numbered.
Quality mismatch: the symbol body is a generic rectangle rather than the conventional polarized capacitor/supercapacitor symbol. This can reduce schematic readability but does not prevent connectivity.
Metadata gap: terminal descriptions are missing (recommended descriptions would identify positive/long lead and negative/short lead, but no edit was authorized).

Footprint and mechanical audit

Current actual geometry versus Eaton source

Table

Feature	Current footprint	Eaton source	Status
Pad count	2	2 leads	Confirmed
Pad centers	x = −1.75 mm and +1.75 mm	P = 3.5 ±0.5 mm	Confirmed nominal pitch
Pitch	3.50 mm	3.5 ±0.5 mm	Confirmed
Pad 1	1.80 × 1.80 mm rectangular PTH	No land size specified	Not specified by datasheet
Pad 2	Ø1.80 mm circular PTH	No land size specified	Not specified by datasheet
Drill	Ø0.90 mm both pads	Lead Ø0.60 ±0.05 mm	Plausible 0.25–0.35 mm diametral clearance, but not an Eaton-confirmed recommendation
Annular ring	0.45 mm radial nominal	Not specified	Not specified by datasheet
Fab body outline	Ø8.00 mm circle	Ø8.0 ±0.5 mm	Confirmed nominal body diameter
Silkscreen body	Ø8.00 mm circle	Ø8.0 ±0.5 mm	Nominal match; silkscreen is not tolerance-expanded
Courtyard	8.8 × 8.8 mm square	Maximum body diameter 8.5 mm	Encloses maximum nominal tolerance with 0.15 mm per-side residual margin; no Eaton courtyard requirement
Polarity mark	`+` at left/Pad 1 side	Datasheet requires polarity and drawing shows +/−	Confirmed in intent
Value text	HSL0814-3R8106-R on fab, disabled in rendered layout	Body marking reference includes voltage/capacitance and other marks	PCB fab text need not duplicate can marking

The current polarity convention is internally coherent: schematic pin 1 + maps to the left rectangular pad adjacent to the + silkscreen; pin 2 − maps to the right circular pad. Eaton’s drawing identifies the longer lead as positive (27 mm nominal) and the shorter lead as negative (22 mm nominal), but does not define numbered pad orientation in a PCB land pattern.

3D model audit

A STEP asset exists: HS0814-3R8106-R_HSL0814-3R8106-R.STEP.
It is attached to the footprint with scale 1 and rotations X = −90°, Y = +90°, Z = 0°.
Placement rule is approximately X = 0, Y = 0.0001 mm, Z = 13.7788 mm.
The platform exposes GLB/STL/OBJ/3MF conversions.
Exact model bounding dimensions and lead geometry could not be independently extracted in the available sandbox because the binary attachment was not delivered to the geometry parser. Consequently, dimensional fidelity is not verified.
The unusually large positive Z placement is a review concern. It may compensate for the STEP file’s internal origin after rotation, but without a successful rendered/model-geometry measurement it cannot be classified as seated correctly or incorrectly.

Prioritized mismatches and risks

High — 3D model seating/dimensions unverified: model uses Z = 13.7788 mm after compound rotation. This may be correct origin compensation or may leave the model floating. Confirm in the 3D viewer or by bounding-box inspection before relying on mechanical exports.
Medium — Manufacturer Name structured property missing: exact manufacturer is Eaton and is present in description/source, but not in the current property list.
Medium — Package or Case Code TO is misleading/non-specific: the part is an 8 × 14 mm radial cylindrical capacitor, not a transistor-style TO package. This can impair search/classification; it does not alter the explicit custom footprint.
Medium — Symbol is not a conventional polarized-capacitor symbol: plain rectangle with +/− pins is electrically usable but visually poor for a supercapacitor library part.
Low — Terminal descriptions absent: no explicit “positive/long lead” and “negative/short lead” descriptions.
Low — Important published ratings are absent from structured properties: ±20% tolerance, 500 mΩ maximum ESR at 1 kHz, voltage floor/surge limits, and current ratings are not encoded. The requested constraint permitted only a Datasheet-property edit, so these were not changed.
Informational — Pad/hole sizes cannot be manufacturer-confirmed: Eaton publishes 0.6 ±0.05 mm lead diameter but no recommended hole/land. The existing 0.9 mm drill and 1.8 mm pads appear mechanically reasonable, but remain library design choices rather than datasheet matches.

Severe-defect assessment

No confirmed defect was found that makes the electrical symbol or footprint unusable as-is. The pin/pad count, nominal pitch, body diameter, and polarity mapping are coherent. The unresolved 3D seating concern affects mechanical confidence and should be checked, but available evidence is insufficient to assert a severe model defect or file a geometry-quality ticket as fact.

Change and verification record

Datasheet property edit: not needed; no mutation made.
Persistence verification: project metadata readback shows the exact official Eaton PDF URL.
Read-only verification performed: project properties, full schematic terminals/properties, rendered symbol SVG, detailed footprint rules/geometry, asset inventory, official web identity search, and focused official-datasheet extraction.
