Table
| Item | Result |
|---|---|
| Individual functional pin descriptions | Not provided |
| Contact numbering | Numeric contacts only |
| Mechanical holes | Two shell / mounting holes provided |
For this connector, the datasheet behaves like a mechanical connector drawing rather than an IC datasheet, so there are no per-pin electrical functions beyond contact numbering.

| Standard class III connector | Yes |
| Flame-retardant insulator | Yes |
| Mechanical PCB layout drawing included | Yes |
Table
Table
| Area | Severity | Finding | Why it matters |
|---|---|---|---|
| Signal-hole drill size | High | Footprint uses 1.15 mm drill for pins 1-9, while the datasheet calls out Ø1.0 ±0.05 recommended PCB holes | Could produce excessive hole clearance, weaker solder fillets, poorer pin retention, and a footprint that no longer matches vendor-recommended land pattern |
| Mounting-hole drill size | Medium | Footprint uses 3.15 mm drill for MH1 / MH2, datasheet shows Ø3.1 +0.05 / 0 | Probably manufacturable, but not an exact match to the drawing |
| Symbol pin electrical types | Medium | All symbol terminals are Unspecified instead of passive/mechanical | Weak ERC behavior and easier to miss connection mistakes in larger designs |
| Part metadata completeness | Medium | BOM lookup did not return a resolved placed BOM item for this part project | Could affect downstream sourcing metadata if this part is reused elsewhere without cleanup |
| Pin description detail | Low | No explicit pin function naming beyond numbers | Acceptable for a connector, but users must rely on numbering only |
The footprint geometry appears internally consistent for a DB9-style staggered connector:
- Row-to-row offset and in-row spacing match the expected 9-way D-sub pattern.
- The only significant dimensional concern visible from the footprint asset is the drill sizing, not the overall pin arrangement.
Table
| Result | Conclusion |
|---|---|
| Datasheet presence | Good |
| Mechanical family match | Good |
| Symbol completeness | Usable, but metadata should be improved |
| Footprint manufacturability risk | Yes: signal drill diameter should be reviewed first |
| Wrong-part-ordering risk | Low to medium |
| Board-failure risk | Medium if the oversized signal holes reduce solder quality or retention |
Table
| Priority | Fix |
|---|---|
| 1 | Change signal pin drills for 1 to 9 to match the datasheet-recommended hole specification |
| 2 | Recheck MH1 and MH2 against the exact mounting-hole tolerance in the drawing |
| 3 | Set signal contacts 1 to 9 to Passive, and set MH1 / MH2 to a mechanical or passive convention |
| 4 | Add a clearer part description that explicitly says 9-position male PCB D-sub if that is the intended sex of this exact variant |
