Table
| Check item | Result | Risk |
|---|---|---|
| Pin functions vs datasheet | Match for pins 1, 2, 3, 5 | Low |
| Missing pin 4 in symbol | Acceptable because datasheet says pin 4 = no pin | Low |
| Pin count interpretation | Potential documentation issue: symbol exposes 4 electrical pins, but package is SIP-5 with one no-pin position | Medium |
| Footprint package style | Appears consistent with a through-hole SIP package | Low |
| Footprint hole style | Through-hole pads present, which matches SIP package expectation | Low |
| Footprint file naming | Mismatch: footprint asset is named TRN10513.kicad_mod, while part MPN is TRN 1-0515 | Medium |
| 3D model naming | Matches part MPN: TRN_1-0515.stp | Low |
Table
| Issue | Why it matters | Severity |
|---|---|---|
| Footprint asset name is TRN10513.kicad_mod instead of TRN 1-0515 | Could lead to wrong part-family reuse, ordering confusion, or silent package mismatch if that footprint was copied from another variant | Medium |
| Datasheet property points to a landing page rather than a direct datasheet PDF | Makes verification harder and caused ambiguous extraction results | Medium |
| Symbol does not explicitly document the package as SIP-5 with NC pin 4 | Someone may incorrectly assume a true 4-pin package | Low-Medium |
Table
| Risk type | Assessment |
|---|---|
| Manufacturing failure | No immediate hard mismatch found in pin order or basic package style |
| Incorrect part ordering | Possible, mainly because the footprint asset name suggests a different model |
| Board failure | Possible only if the borrowed footprint geometry is not actually identical to the TRN 1-0515 package |
| Documentation confusion | Likely unless the NC pin and exact package family are documented clearly |
Table
| Priority | Fix |
|---|---|
| High | Replace the datasheet property with a direct official PDF URL if available |
| High | Verify the pad pitch and body dimensions of TRN10513.kicad_mod against the TRN 1-0515 package drawing |
| Medium | Rename the footprint asset so it matches TRN 1-0515 or the shared package family name |
| Medium | Add a package/property note such as SIP-5, pin 4 = NC |
| Medium | Add explicit pin metadata to the part so pin functions are machine-readable, not only encoded in terminal names |
.kicad_mod asset against the package dimensions.
