Pin description check
| Item | Result |
|---|---|
| Pin numbering in datasheet | Circuits are numbered, with Circuit 1 identified on the drawing |
| Pin names/functions | This is a passive connector; no unique signal-function pin names are defined in the datasheet beyond circuit numbering |
| Project symbol | Matches the expected simple numbered-circuit representation: 1, 2, 3, 4 |
Package and PCB dimensions
| Dimension / feature | Datasheet |
|---|---|
| Body length A | 12.62 mm |
| Pattern length B for 4 circuits | 7.62 mm |
| Overall height shown | 13.59 mm |
| Pitch | 2.54 mm typ |
| PCB hole diameter | 1.09 ± 0.08 mm |
| Recommended PCB thickness | 1.57 mm |
| Tail length | 2.90 mm REF |
| Restricted area | 7.0 mm typ |
| PCB layout view | Component side |
Cross-check: symbol and footprint vs datasheet
| Check | Result | Risk |
|---|---|---|
| Circuit count | Symbol has 4 terminals and footprint has 4 pads | No issue |
| Numbering continuity | Symbol and footprint both use 1-4 numbering | No issue |
| Pitch | Footprint pad pitch is 2.54 mm | Matches datasheet |
| Span for 4 circuits | Footprint end-to-end pin span is 7.62 mm | Matches datasheet |
| Drill size | Footprint uses 1.15 mm drill vs datasheet 1.09 ± 0.08 mm | Acceptable, within datasheet tolerance band |
| Pad style | Pin 1 rectangular, others circular | Good for pin-1 identification |
| Package envelope | Footprint naming and courtyard/body dimensions align with 12.62 mm body length and 13.59 mm height shown in datasheet | Looks consistent |
| 3D model presence | Present | Good |
| Datasheet linkage | Already set | Good |
Mismatches / issues flagged
| Issue | Severity | Why it matters |
|---|---|---|
| Symbol terminals are typed as Unspecified instead of passive connector terminals | Low | Could weaken ERC clarity, but not a manufacturing or ordering blocker |
| No explicit per-pin descriptions beyond circuit numbers | Low | Fine for a passive header, but adding clearer terminal metadata could improve reuse |
| No obvious footprint mismatch found | None | I did not find a manufacturing-critical geometry conflict |
| No obvious ordering mismatch found | None | Project MPN and datasheet agree on 171974-0004 |
- The part project already had a valid datasheet URL, so no web lookup or property update was needed.
- The symbol, pad count, numbering, pitch, and hole sizing all appear consistent with the Molex drawing.
- I found no manufacturing-critical mismatch and no obvious wrong-part ordering risk.
- The only cleanup worth considering is improving terminal metadata from Unspecified to passive-style connector semantics for better library quality and ERC behavior.
