Cross-check summary
| Check item | Result | Notes |
|---|---|---|
| Signal position count | Pass | Project has 26 signal positions, matching datasheet |
| Mechanical holes | Pass | Project includes 2 mounting holes, matching datasheet |
| Total represented terminals/pads | Pass | 28 total = 26 + 2 mounting holes |
| Pad numbering continuity | Pass | Positions 1-26 are present |
| Mounting hole naming | Pass with caveat | Mechanical holes are clearly separated as MH pads |
| Footprint overall length | Pass | Footprint body outline is 39.5 mm, matching datasheet |
| Mounting-hole span | Pass | Footprint uses 32.5 mm center spacing |
| Mounting-hole drill | Pass | Footprint drill 3.4 mm aligns with datasheet Ø3.3 ±0.1 mm |
| Signal-hole drill | Borderline / acceptable | Footprint drill is 1.5 mm; datasheet gives Ø1.3 +0.2 mm, so 1.5 mm is at the upper limit |
| Contact pattern geometry | Pass | Footprint row/column geometry matches the datasheet pitch pattern |
| Pin descriptions | Incomplete | Datasheet has no pin-function table, so numbered pins are acceptable |
| Symbol electrical pin types | Issue | All are Unspecified |
| Symbol implementation style | Usability issue | Represented as many terminal primitives rather than a richer connector symbol |
Findings
| Severity | Finding | Why it matters |
|---|---|---|
| Medium | All symbol pins are Unspecified electrical type | Weak ERC behavior; easier to miss connection issues in downstream designs |
| Medium | Pin entries show undefined pin objects/descriptions | Reduces clarity and increases risk of integration mistakes |
| Low | Datasheet is a customer drawing, not a full electrical spec sheet | Important electrical/environmental limits are missing, so part validation is incomplete |
| Low | Signal-hole drill is set to 1.5 mm, the top end of the stated datasheet range | Likely manufacturable, but leaves no margin if the recommended interpretation was intended to be tighter |
| Low | Symbol is minimal and purely numeric | Fine for a connector with no pin functions, but not ideal for usability |
Conclusion
| Area | Verdict |
|---|---|
| Ordering risk | Low - MPN and mechanical identity are consistent |
| Manufacturing risk | Low to medium - footprint looks mechanically consistent with the drawing |
| Board failure risk from symbol/footprint mismatch | Low based on available evidence |
| Main remaining concern | Missing full electrical/specification data and weak symbol metadata |
Highest-value improvements
| Priority | Improvement |
|---|---|
| 1 | Set pin electrical types for the connector pins and mounting holes |
| 2 | Add pin descriptions such as Position 1 through Position 26 and mark mounting holes as mechanical |
| 3 | Confirm whether 1.5 mm finished drill is your intended fabrication target or whether you want slightly more annular margin based on the mating header lead dimensions |
| 4 | Add a second source document with full product specifications if you need environmental/electrical validation |
