Table
| Area | Result | Notes |
|---|---|---|
| MPN | Pass | Project MPN matches datasheet part family and 10-circuit side-entry header. |
| Position count | Pass | 10 signal circuits are present. |
| Mechanical tabs included | Pass | 2 extra SMT pads exist and align with reinforcement tabs. |
| Footprint pitch | Pass | Footprint uses 1.25 mm pitch for pads 1-10. |
| Signal pad width | Pass | Footprint uses 0.600 mm, matching datasheet. |
| Mechanical tab pad width | Pass | Footprint uses 1.000 mm, matching datasheet. |
| Side-entry geometry | Pass | Footprint dimensions align with side-entry style, not top-entry style. |
| Datasheet orientation note | Needs care | Datasheet layout is viewed from mounting surface; footprint appears consistent, but this is a common source of mirrored footprints if manually recreated. |
| Symbol pin metadata | Issue | Pin names/descriptions are effectively undefined in the current schematic representation. |
| Symbol structure | Issue | The part is represented as separate terminal elements rather than one unified connector symbol. |
| Electrical pin typing | Issue | All pins are marked Unspecified. |
| Designator consistency | Minor issue | Project designator prefix is J, while internal terminal elements show P prefix metadata. |
Table
| Severity | Finding | Risk |
|---|---|---|
| High | The schematic symbol is not a conventional single 10-pin connector symbol; it is split into separate terminal elements plus two mounting tabs. | Easier to miswire, harder to review, and higher risk of pin-order mistakes during reuse. |
| Medium | Pin names are undefined and pin types are unspecified. | ERC quality is reduced; users may connect the wrong circuit because only numbers are visible. |
| Medium | Reinforcement tabs are present, but they are not clearly differentiated as mechanical-only in the symbol metadata. | A user could mistakenly treat them as signal pins in the part definition workflow. |
| Low | Designator-prefix metadata is inconsistent between project-level connector identity and internal terminal elements. | Mostly a library cleanliness issue, but can create confusion in generated symbols/docs. |
Table
| Category | Conclusion |
|---|---|
| Wrong part ordered | Low risk if the MPN is used directly, because the MPN and package family align. |
| Footprint manufacturing failure | Low risk based on the extracted pad geometry; the footprint appears consistent with the datasheet side-entry land pattern. |
| Board assembly / fit issue | Low risk from the footprint itself, assuming the side-entry orientation is what you intended. |
| Board failure due to symbol mismatch | Medium risk at the design-entry stage, because the symbol metadata is weak and can enable wiring mistakes. |
