Cross-check result
| Check | Status | Notes |
|---|---|---|
| Pin count | Pass | Project has 4 pins; datasheet requires 4 pins |
| Pin numbers | Pass | ANODE=1, CATHODE=2, EMITTER=3, COLLECTOR=4 |
| Pin names | Pass | Names match datasheet functions |
| Symbol side grouping | Pass | Input LED pins on left, transistor output pins on right; consistent with datasheet top-view pinout |
| Footprint pitch | Pass | Footprint uses 1.27 mm pin spacing |
| Footprint body size | Pass | Fabrication outline is approximately 4.4 mm x 2.7 mm, matching datasheet body size |
| Lead span / pad placement | Pass | Pad centers at about ±3.2 mm are consistent with 7.0 mm overall span |
| Pad count / numbering | Pass | 4 SMD pads numbered 1-4 |
| 3D model presence | Pass | STEP model exists |
| Manufacturing-risk mismatch | No critical mismatch found | Nothing obvious that would cause guaranteed assembly failure |
Issues flagged
| Severity | Issue | Why it matters |
|---|---|---|
| Medium | Footprint asset is named SOIC127P700X210-4N while the datasheet package is 4-pin SSOP | Geometry appears correct, but the naming mismatch could confuse future reuse, library search, or procurement review |
| Low | Schematic terminal pin types are all Unspecified | Not a manufacturing issue, but it weakens ERC quality and part metadata completeness |
| Low | Project package property is just SSOP | Functional, but not very specific; 4-pin SSOP, 1.27 mm pitch would be clearer for ordering/review |
- The current symbol-to-datasheet mapping looks correct.
- The current footprint geometry looks consistent with the datasheet package.
- I do not see a critical mismatch that would likely cause board failure or wrong pin mapping.
- The main cleanup item is the SOIC-vs-SSOP footprint naming inconsistency, which is metadata/library hygiene rather than a clear geometric error.
Ready.
