Part Information Review and Verification
Thought for 3 mins 5 sec
I reviewed the part project against the currently stored datasheet URL and the official Molex sales drawing. The part-project sync guidance says to treat the datasheet as the source of truth, verify exact project property names, and flag pin-count or metadata mismatches rather than guessing missing details
Summary
What matches
Table
| Item | Current project | Datasheet / official drawing | Status |
|---|---|---|---|
| MPN | 73251-1350 | 73251-1350 / 0732511350 | Match |
| Manufacturer | Molex | Molex | Match |
| Designator Prefix | J | Connector-style prefix is appropriate | Match |
| Mount | Surface Mount | Vertical PCB SMT | Match |
| Pin count | 5 terminal components: 1, 2, 3, 4, 5 | Official drawing shows 5 SMT pads total: 1 center + 4 outer shield pads | Match |
| Footprint topology | 5-pad footprint present | Official drawing shows 5 SMT pads | Match |
Table
| Item | Finding | Status |
|---|---|---|
| Datasheet URL quality | A datasheet URL is already set, so no search/update was required by your rule. But it points to a third-party archive, not the official Molex PDF. | Not wrong, but not ideal |
| Package / Case Code | No package or case-code property found | Missing |
| Pin descriptions | No per-pin description metadata found | Missing |
| Pin type classification | All five terminal components are Pin Type = Unspecified | Needs review |
| Part Type normalization | Connectors is usable, but Connector would be more consistent with singular Flux part typing | Minor inconsistency |
| Description quality | Current description is brief and market-facing, but not ideal as a crisp functional library description | Could improve |

The official Molex drawing indicates:
- 1 center contact for signal
- 4 outer body/shield SMT terminations for the grounded shell
Your symbol has exactly five terminals, which is consistent.
Likely mapping
- One of 1, 2, 3, 4, 5 should be the center signal contact
- The other four should be shell / shield / ground tabs
The official drawing text I could extract does not include explicit pin numbers, so I cannot prove which existing designator maps to center vs shield from numbering alone. Because the sync rules forbid guessing pin assignments, I’m flagging this as an ambiguity rather than asserting a remap
Footprint cross-check
Official drawing / land pattern indicates:
- 4 outer square pads: 1.905 ± 0.05 mm
- 1 center square pad: 4.75 ± 0.05 mm
- Offset to outer pads: 2.37 ± 0.05 mm
- Total SMT pad count: 5
- No through-holes shown
Your layout contains a footprint asset
Limitation
73251-1350.kicad_mod and five pad nodes, which is structurally consistent with the Molex drawing.I could verify pad count and general topology, but not exact pad dimensions from the current layout node dump alone. So:
- No obvious footprint mismatch found
- Exact dimension verification remains incomplete unless I inspect the footprint geometry in more detail
Based on the datasheet-sync workflow, the most useful property improvements would be
Table
| Property | Recommended value |
|---|---|
| Description | SMA jack connector, vertical PCB surface-mount receptacle, 50 Ω, 18 GHz |
| Part Type | Connector |
| Package or Case Code | Vertical PCB SMT or the exact package text you want to standardize on |
| Datasheet URL | Keep current value unless you want to normalize to the official Molex PDF |
| Pin Type for center contact | Passive or Unspecified |
| Pin Type for four shell tabs | Ground |
| Pin Description for center contact | Center signal contact |
| Pin Description for shell tabs | Shell ground tab |

- No datasheet URL update was required, because the property is already populated.
- The project is mostly correct at a structural level:
- MPN/manufacturer/mounting match
- symbol and footprint both appear to have the correct 5-contact structure
- The main issues are metadata quality, not gross geometry:
- no package/case code
- no pin descriptions
- all pins still marked
Unspecified - center-vs-shield pin identity is not explicitly documented in the current symbol data
I can take care of the property cleanup next.
