Part Metadata Audit and Review
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.
Thought for 19 sec
I’ll audit the current part metadata, find and attach an official datasheet if missing, then compare the symbol/pads/footprint details against the datasheet and summarize any mismatches.
Worked for 23 mins 56 sec
Completed the part audit and saved the detailed findings in Part Audit Report.
Key issue: the project metadata/MPN says
PCAPH, the footprint is for T520D107M010ATE080, and the 3D model is T541X337M016AH6510, so the part is internally inconsistent. The symbol also needs polarity/pin descriptions added for the two capacitor terminals.Fix metadata mismatch
Use T541 model

The T541 query did not return complete mechanical table details from OCR, so any exact land-pattern verification for T541X337M016AH6510 should be confirmed directly from the manufacturer PDF before release.
Footprint observed in project
The footprint asset is named
T520D107M010ATE080.kicad_mod and contains two SMD rectangular pads:Table
| Pad | Position | Size | Rotation |
|---|---|---|---|
| 1 | x = -2.672194 mm, y = 0 | 2.499995 mm × 2.560396 mm | 90° |
| 2 | x = +2.672194 mm, y = 0 | 2.499995 mm × 2.560396 mm | 90° |
Silkscreen/fab outline indicates a body approximately 7.6 mm × 4.3 mm with a positive polarity mark drawn on the left side. The footprint value text is
CAPMP7.6X4.3_3.1N_KEM.Cross-check results
Table
| Item checked | Result | Notes |
|---|---|---|
| Pin count | Pass | Project has two terminals and footprint has two pads, consistent with both capacitor candidates. |
| Symbol pin names | Mismatch / incomplete | Symbol terminals are generic 1 and 2 with pin shown as undefined; no +/-, anode/cathode, or polarity description is present. |
| Pin descriptions | Mismatch / incomplete | Both terminals have Pin Type: Unspecified; no capacitor polarity metadata is captured. |
| MPN consistency | Mismatch | Project metadata says PCAPH, footprint is for T520D107M010ATE080, and 3D model is T541X337M016AH6510. These cannot all represent the same exact purchasable part. |
| Datasheet consistency | Mismatch risk | Existing indexed URL points to KEMET T540/T541, while the PCB footprint asset is a T520D107M010ATE080 footprint. |
| Footprint vs T520D107M010ATE080 | Mostly consistent | Footprint body and pad geometry are broadly consistent with a KEMET D-case 7343-31 tantalum capacitor. Pad dimensions are close to KEMET D-case land recommendations, though exact density-level match should be selected intentionally. |
| Footprint vs T541X337M016AH6510 | Mismatch / unverified | The 3D model MPN is T541X337M016AH6510; the footprint asset is not named for that part and should not be assumed compatible without the T541 X-case land pattern. |
| 3D model vs footprint | Mismatch risk | 3D model is T541X337M016AH6510 while footprint is T520D107M010ATE080, so mechanical height/body/terminal geometry may be wrong. |
Recommended fixes
- Decide the intended exact part:
- If the intended part is
T520D107M010ATE080, set the part MPN toT520D107M010ATE080, manufacturer toKEMET, datasheet to the T52x/T530 datasheet, package to D / 7343-31, and replace the 3D model with the matching T520D107M010ATE080 model. - If the intended part is
T541X337M016AH6510, replace the footprint with the official T541X337M016AH6510 / X-case footprint and keep the T541 3D model.
- If the intended part is
- Update the schematic symbol terminals:
- Pin 1:
+/ Anode / Positive terminal, Pin TypePassive. - Pin 2:
-/ Cathode / Negative terminal, Pin TypePassive.
- Pin 1:
- Add or correct metadata: Manufacturer Name, Manufacturer Part Number, Part Type = Capacitor, Capacitor Type = Tantalum/Polymer Electrolytic, Capacitance, Voltage Rating, ESR, Tolerance, Package or Case Code, Operating Temperature, and Datasheet URL.
- Verify the footprint land pattern against the chosen exact datasheet package table before release.
Datasheet URL update status
A datasheet URL was already present in indexed project metadata, so no URL replacement was made. However, the self-datasheet lookup did not see the datasheet property directly, which suggests the part-project datasheet property may not be populated in the canonical field even though the search index reports one. This should be corrected when finalizing the exact MPN.
