Part Audit Review
Thought for 7 sec
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.
Worked for 1 min 35 sec
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.

Part Audit — SCHURTER 0031.8225
Reviewed the available part metadata, schematic terminals, PCB footprint, and stored datasheet for the SCHURTER OGN-SMD 5 × 20 mm fuseholder...
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.Fix metadata and graphics

Table
| Field | Current value | Assessment |
|---|---|---|
| Name / MPN | 0031.8225 | Matches datasheet order number |
| Manufacturer Name | SCHURTER | Matches datasheet |
| Library manufacturer classification | Other | Metadata mismatch; should be SCHURTER if this field is editable at the library level |
| Description | OGN-SMD FUSEHOLDER 5X20 | Correct but terse |
| Terminal count | 2 | Correct |
| Mount | Surface Mount | Correct |
| Package or Case Code | SMD | Broad but correct; not a standardized semiconductor package |
| Part Type | blank | Missing; should identify a fuse holder / fuse block |
| Designator Prefix | U | Poor fit; F or FH is more conventional for a fuse/fuseholder |
| Datasheet URL | http://www.schurterinc.com/bundles/snceschurter/epim/_ProdPool_/newDS/en/typ_OGN-SMD.pdf | 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 1andFuse 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
Uis unconventional.ForFHwould 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(orFif 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.
