Part Datasheet Audit
Thought for 11 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 37 sec
The part resolves to Littelfuse 05200101Z, a 520-series 5×20 mm PCB fuse block. I found the official manufacturer datasheet and am now validating the terminal mapping and mechanical land pattern before recording the audit.

Part Datasheet Audit — Littelfuse 05200101Z
The part is intended to represent Littelfuse 05200101Z, a 520 Series Metric OMNI-BLOK molded-base PCB fuse block for 5×20 mm cartridge fuses...
Audit complete. I added the official Littelfuse datasheet URL and confirmed the 24.13 mm pad pitch and 1.397 mm drills match the recommended land pattern.
Key issues: MPN is incorrectly
FUSE instead of 05200101Z, manufacturer is missing, terminal types/descriptions are unset, and the 3D model appears inaccurate/vertically offset. Full findings are in Part Datasheet Audit.Fix and verify

Part Datasheet Audit — Littelfuse 05200101Z
Result
The part is intended to represent Littelfuse 05200101Z, a 520 Series Metric OMNI-BLOK molded-base PCB fuse block for 5×20 mm cartridge fuses. The missing part-level Datasheet URL was set to the official manufacturer source:
No symbol, footprint, pad, or 3D geometry was changed during this audit.
Existing metadata
Table
| Field | Existing value | Assessment |
|---|---|---|
| Project/part name | FUSE | Generic/incomplete |
| Description | FUSE | Incomplete |
| Manufacturer Part Number | FUSE | Mismatch — should be 05200101Z |
| Manufacturer Name | Not set | Missing — should be Littelfuse |
| Part Type | Circuit Protection Devices | Broad but reasonable |
| Designator Prefix | F | Correct |
| Datasheet URL | Official Littelfuse URL above | Corrected |
| Pin count | Two terminals and two pads | Correct for this holder |
Key manufacturer specifications
- Product: 520 Series Metric OMNI-BLOK molded-base fuse block
- Compatible fuse: 5×20 mm cartridge fuse
- Mounting: PCB through-hole
- UL rating: 10 A, 600 VAC/VDC
- VDE rating: 6.3 A, 250 VAC/VDC
- Terminal material: tin-plated brass
- Recommended PCB terminal pitch: 24.13 ±0.13 mm
- Recommended PCB hole diameter: 1.4 mm typical
Symbol audit
Table
| Terminal | Number | Description | Electrical type |
|---|---|---|---|
| 1 | 1 | Not set | Unspecified |
| 2 | 2 | Not set | Unspecified |
- Terminal-to-pad mapping is consistent: 1→1 and 2→2.
- The holder is non-polarized, so either terminal may be the input or output.
- Both terminal types should conventionally be Passive.
- Suggested descriptions: Fuse contact / terminal.
- The symbol is a generic rectangle rather than a recognizable fuse-holder symbol. This is a presentation issue, not an electrical mapping error.
Footprint audit
Table
| Pad | Position | Copper diameter | Drill | Type |
|---|---|---|---|---|
| 1 | (0, 0) mm | 1.905 mm circular | 1.397 mm | Plated through-hole |
| 2 | (24.13, 0) mm | 1.905 mm circular | 1.397 mm | Plated through-hole |
- Pad pitch: 24.13 mm, matching the manufacturer recommendation.
- Drill: 1.397 mm, effectively the recommended 1.4 mm.
- Approximate radial annular ring: 0.254 mm.
- Fab outline: approximately 26.162 × 10.16 mm.
- Silk outline: approximately 26.416 × 10.414 mm.
- Courtyard: approximately 26.67 × 10.668 mm.
- Pin-1 marker is present.
The basic pad pattern matches the manufacturer drawing. The fab/silk are simplified rectangles and may not represent every clip or installed-fuse projection, so full mechanical clearance—particularly the drawing’s larger 36.6 mm referenced dimension—remains unverified.
3D model audit
Asset:
FUSE_05200101Z_LTF.step- Approximate model envelope: 26.162 × 10.16 × 12.7 mm.
- The model looks like a closed rectangular box rather than the open molded base and exposed fuse clips.
- The model height does not clearly align with the approximately 10.2 mm body-height dimension in the drawing.
- A 2 mm Z placement offset makes seating on the PCB questionable.
The 3D model is not sufficiently faithful for enclosure/clearance validation, although it does not affect manufactured copper geometry.
Flagged mismatches and missing information
- Manufacturer Part Number is incorrect:
FUSEinstead of05200101Z. - Manufacturer Name is missing: should be
Littelfuse. - Name and description are generic and omit series, fuse size, and mounting type.
- Electrical ratings and terminal material are absent from metadata.
- Terminal descriptions are missing.
- Terminal types are
Unspecifiedinstead ofPassive. - Symbol graphic is generic.
- Fab/silk do not fully communicate all mechanical projections.
- 3D model appears simplified/inaccurate and may be vertically offset.
Recommended corrections
- Set MPN to
05200101Z. - Set Manufacturer Name to
Littelfuse. - Use a description such as:
520 Series Metric OMNI-BLOK PCB fuse block for 5×20 mm cartridge fuses. - Change both terminal electrical types to
Passiveand add terminal descriptions. - Replace or correct the 3D model before relying on it for enclosure clearance.
- Consider refining fab/courtyard geometry after interpreting all mechanical projections in the manufacturer drawing.
