Cross-check of symbol and footprint vs available official data

Check	Result	Risk
Pin count	Footprint and symbol both implement 26 signal terminals plus 2 mounting holes	Low
Part style	Footprint is through-hole, right-angle, consistent with the product description	Low
Body envelope	Footprint outline is about 39.5 mm x 36.5 mm, matching the official dimensions seen on the TE product page	Low
Mounting holes	Two mechanical holes are present as MH1 and MH2	Low
Pin numbering presence	Numbered positions exist in the symbol and footprint	Low
Pin electrical types	All schematic terminals are Unspecified	Medium
Pin names / functions	Symbol uses only numeric terminals; no cavity labels beyond numbers	Medium
Datasheet-to-footprint dimensional verification	Incomplete, because the scanned datasheet does not include the product drawing / recommended PCB layout	High
Drill / pad validation	Current footprint uses 1.5 mm drill and 2.25 mm pad for signal pins, but I could not verify these against an official TE drawing from the scanned PDF	High
Mechanical hole validation	Current footprint uses 3.4 mm drill, but I could not verify against the official product drawing from the scanned PDF	High

Manufacturing / ordering / failure risks flagged

Issue	Why it matters
Missing verified product drawing dimensions	Without the official product drawing, signal-hole diameters, mounting-hole diameters, and row spacing cannot be fully confirmed. This is the biggest manufacturing risk.
No explicit package/footprint validation source in the scanned PDF	The current footprint may still be correct, but it is not fully traceable to the official drawing from the scanned PDF.
Unspecified schematic pin types	This can reduce ERC usefulness and make downstream integration less reliable.
No cavity function metadata	For a connector part, lack of named cavity metadata increases risk of wiring mistakes in end-use designs.

Bottom line

What looks correct: overall part identity, 26-position count, 2 mounting holes, right-angle through-hole style, and overall body size alignment.
What remains risky: the footprint’s hole sizes, exact pad geometry, and mounting-hole geometry are not fully verifiable from the currently scanned datasheet PDF.
Most important next correction target: obtain the official TE product drawing for 6437288-4 and compare it directly against the current footprint asset 64372884.kicad_mod.

If you want, I can next search the official TE product drawing PDF and do a line-by-line footprint verification against it.
