Pin / terminal interpretation from the datasheet vs project
| Project terminal model | Datasheet meaning | Status |
|---|---|---|
| Pins 1-4 | Signal contacts on 0.50 mm pitch | Matches |
| Pins 5-6 labeled as mount pads in project | Mechanical hold-down tabs, called NAIL in drawing | Matches |
| Dual-contact behavior | Connector is a dual-contact type | Not represented in symbol semantics |
Package / land pattern details extracted
| Feature | Datasheet value |
|---|---|
| Signal pad pitch | 0.50 mm |
| Signal pad board pattern | 0.79 ±0.05 mm x 0.30 ±0.05 mm |
| Signal stencil opening | 0.70 mm x 0.30 mm |

Cross-check of schematic symbol and footprint
| Check | Result | Notes |
|---|---|---|
| Total terminal count | Pass | Project models 6 terminals, consistent with 4 circuits + 2 nails |
| Signal pin count | Pass | Four signal pads present |
| Mechanical pad count | Pass | Two hold-down pads present |
| Signal pad pitch | Pass | Footprint uses 0.50 mm spacing |
| Signal pad size | Likely pass | Footprint pads are 0.30 x 0.70 mm; this aligns with the datasheet stencil opening and is close to the recommended land pattern length |
| Nail pad size | Pass | Footprint pads are 0.30 x 1.00 mm, matching the datasheet nail dimensions by orientation |
| 3D model present | Pass | STEP model exists |
| Pin numbering present | Pass | Pins 1-4 plus two mount pads are represented |
| Symbol semantic quality | Concern | All symbol pins are typed Unspecified |
| Symbol clarity for mechanical pins | Concern | Mechanical tabs are present but modeled as generic terminals rather than clearly marked mechanical / shield tabs |
| Datasheet consistency in project metadata | Minor inconsistency | Project description says -40°C to +85°C, but official Molex drawing gives -40°C to +105°C |
Issues that could matter
| Severity | Issue | Why it matters |
|---|---|---|
| Medium | Project description temperature range is out of sync with the official Molex drawing | Could cause incorrect filtering, wrong environmental assumptions, or incorrect downstream part selection |
| Medium | Symbol pins are all Unspecified | Can confuse reuse, documentation, and automated checks in larger designs |
| Low | Generic symbol does not clearly distinguish signal contacts from mechanical nails | Increases risk of user wiring a mounting tab as if it were an electrical contact |
| Low | Dual-contact behavior is not explicit in the symbol metadata | Could mislead a user about mating/contact behavior, though it does not by itself create a PCB manufacturing failure |
Manufacturing / ordering risk assessment
| Risk area | Verdict |
|---|---|
| Wrong part number risk | Low |
| Footprint pad-count mismatch risk | Low |
| Catastrophic PCB fit risk | Low, based on retrieved pad geometry and 3D asset presence |
| Assembly ambiguity risk | Medium-low because the symbol is generic and mechanical pads are not strongly differentiated |
| Documentation / library-quality risk | Medium |
- I do not see a major pad-count or obvious footprint geometry mismatch that would likely cause immediate manufacturing failure.
- The main problems are metadata and symbol-quality issues, not the footprint itself.
- The most important corrections would be:
- Update the part metadata temperature range to -40°C to +105°C
- Mark the two nail pads explicitly as mechanical / mounting tabs
- Give the signal pins and mechanical pins clearer semantic types and labels
Ready.
