Pin description check

Table

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

Cross-check: symbol and footprint vs datasheet

Table

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

Table

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

Bottom line

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.
