Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, locate the official datasheet if needed, update its Datasheet property, then compare the symbol, footprint, and pin descriptions against the manufacturer documentation.
The part already has a SCHURTER datasheet URL, so no URL insertion is currently needed. I’m validating that document and checking the two-terminal symbol and SMD land pattern against it.
Audit complete. The official SCHURTER datasheet was already set, so no Datasheet property update was required; the critical footprint geometry matches the recommended 6 × 6 mm pads with an 11 mm gap.
Flagged issues include blank Part Type, unconventional U prefix, unspecified terminal types/descriptions, HTTP rather than HTTPS datasheet URL, and apparently displaced silkscreen/reference graphics. Full specifications and findings are in Part Audit — SCHURTER 0031.8225.
Official SCHURTER domain and document; already set, so no required insertion. HTTPS is preferable: https://www.schurterinc.com/bundles/snceschurter/epim/_ProdPool_/newDS/en/typ_OGN-SMD.pdf

Schematic symbol cross-check
The symbol contains two terminals numbered 1 and 2. This is electrically correct for a single-circuit fuseholder, and the terminal numbers correspond to footprint pads 1 and 2.
Symbol issues
Both terminal pin types are Unspecified. Passive is the more accurate electrical classification.
No functional pin descriptions are present. Suggested descriptions: Fuse terminal 1 and Fuse terminal 2.
The symbol is represented as two terminal primitives; confirm that the rendered graphic clearly communicates a fuseholder/fuse path rather than two unrelated pins.
Designator prefix U is unconventional. F or FH would make BOM and schematic intent clearer.
The holder is non-polarized, so swapping terminal 1 and terminal 2 has no electrical effect.
Footprint cross-check
Verified matches
Two SMD rectangular pads: correct.
Pad size: 6.0 mm × 6.0 mm: matches the recommended soldering pads.
Pad centers: −8.5 mm and +8.5 mm, giving 17.0 mm center-to-center spacing.
With 6 mm pads, the inner pad gap is 11.0 mm: matches the datasheet layout.
Fabrication outline: 22.7 mm × 9.6 mm: matches the principal body dimensions shown in the datasheet.
Footprint has a STEP model and pad numbering is consistent with the symbol.
Footprint concerns
The silkscreen geometry has a project-level position override of approximately +1.8009 mm X and −14.4806 mm Y. This appears to displace the silkscreen far away from the footprint body and should be visually inspected/corrected.
The reference text also has a large Y offset (~11.4 mm). This may be intentional for visibility, but is unusually distant from the body.
The courtyard is asymmetric (approximately X −13.4 to +12.5 mm). It may reflect installation/handling clearance, but should be checked against the intended assembly courtyard convention.
The footprint includes degenerate zero-length silk line/arc artifacts from import. They are not electrically harmful but reduce asset cleanliness.
The datasheet’s full height and installation geometry cannot be completely validated from 2D copper alone; the STEP model should be visually checked against 22.7 mm length, 10.8 mm maximum width, and 13.2 mm overall height.
Overall verdict
The critical manufacturing geometry—two pads, 6 × 6 mm pad size, 11 mm inner gap, 17 mm pad-center spacing, and 22.7 × 9.6 mm body outline—matches the datasheet. The main issues are metadata quality and asset presentation rather than copper geometry: blank Part Type, generic manufacturer classification, unconventional U prefix, unspecified pin types/descriptions, and apparently displaced silkscreen/reference graphics.
Recommended corrections
Change Part Type to Fuse Holder / Fuse Block.
Change designator prefix to FH (or F if required by the project convention).
Set both terminals to Passive and add functional descriptions.
Replace the stored HTTP datasheet link with the HTTPS equivalent when convenient.
Re-center the silkscreen and review the reference text/courtyard placement.
Visually compare the STEP model dimensions and seating to the manufacturer mechanical drawing.
