Step 3: Datasheet scan and extracted metadata
I also followed the link chain embedded in the existing PDF and scanned the official Würth datasheet here:

Table
| Area | Datasheet | In project | Status | Risk |
|---|---|---|---|---|
| Pin count | 2 | 2 | Match | Low |
| Pad pitch | 3.5 mm | 3.5 mm | Match | Low |
| Drill size | 1.2 ±0.10 mm recommended | 1.2 mm | Match | Low |
| Pad outer diameter | 2.0 ±0.10 mm recommended | 1.8 mm | Mismatch | Medium-High |
| Symbol pin labels | 1, 2 | Pins exist as separate symbols but labels/functions are undefined | Mismatch / incomplete | Medium |
| Symbol organization | One 2-position connector | Two separate one-pin symbols: 1, 2 | Mismatch | High |
| Designator prefix | Connector-style part, project property says J | Symbol elements use prefix P | Mismatch | Medium |
| Footprint mechanical envelope | 7.0 mm x 10.0 mm x 8.4 mm body | Fab outline in footprint asset appears inconsistent with those body dimensions | Needs verification | Medium |
Table
| Severity | Issue | Why it matters |
|---|---|---|
| High | The part-project schematic is built as two separate one-pin symbols instead of one 2-pin connector symbol | This can break usability when the part is placed into real designs, confuse connectivity, and create symbol-to-footprint mapping problems |
| High | Symbol pins are undefined / unspecified rather than clearly defined as pin 1 and pin 2 | Increases risk of incorrect pin mapping, poor documentation, and library-quality issues |
| Medium-High | Footprint pad diameter is 1.8 mm, while the recommended outer pad feature is 2.0 ±0.10 mm | Reduced annular ring can hurt manufacturability and robustness, especially with THT assembly tolerances |
| Medium | Designator prefix is inconsistent: project says J, symbol elements show P | Can cause connector naming inconsistency in downstream designs and BOM/readability problems |
| Medium | The footprint body outline appears inconsistent with the datasheet’s 7.0 mm x 10.0 mm body dimensions | May cause silkscreen/fab/mechanical interference errors even if hole pattern is usable |
Table
| Item | Result |
|---|---|
| Pin count | Correct |
| Pitch | Correct |
| Drill diameter | Correct |
| 3D model present | Yes |
Table
| Item | Priority |
|---|---|
| Replace the two separate one-pin symbols with a single proper 2-pin connector symbol | Highest |
| Define pins explicitly as 1 and 2 with proper types | High |
| Increase THT pad OD from 1.8 mm toward the datasheet-recommended 2.0 mm | High |
| Align symbol prefix to J consistently | Medium |
| Verify the fab/silkscreen body outline against 7.0 mm x 10.0 mm x 8.4 mm | Medium |
If you want, I can next determine exactly which of those fixes I’m able to apply in this part project.
