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

What is missing or weak

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

Key specs found

Symbol / pin cross-check

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

Mismatch / ambiguity

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 73251-1350.kicad_mod and five pad nodes, which is structurally consistent with the Molex drawing.

Limitation

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

Recommended metadata cleanup

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`

Official Molex source I found

Official part page: https://www.molex.com/en-us/products/part-detail/732511350
Official drawing PDF: https://www.molex.com/content/dam/molex/molex-dot-com/products/automated/en-us/salesdrawingpdf/732/73251/732511350_sd.pdf

Bottom line

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.
