Overall footprint width class	Match with product page height/width class around 5.03 mm

Issues flagged

Severity	Finding	Why it matters
High	Symbol pins are reported as undefined with Pin Type: Unspecified for all 50 terminals	This can degrade ERC quality and increase risk of incorrect symbol behavior in downstream designs
Medium	Project-level designator prefix is J, but symbol terminal properties show Designator Prefix: P	Not a manufacturing failure by itself, but can cause library inconsistency and confusion when instantiating the part
High, needs manual confirmation	Footprint file uses 0.95 mm drill and 1.425 mm pad size, while the extracted customer drawing data reported 1.02 mm ± 0.05 mm hole and 1.55 mm min pad diameter	If the drawing extraction is correct, the current footprint may be undersized, creating assembly risk, poor annular ring, or insertion problems
Medium	Datasheet sources are internally inconsistent on max operating temperature: product page 105 °C vs spec 125 °C	This is a part-documentation discrepancy that should be resolved before using the part at elevated temperature limits

Bottom line

The symbol-to-footprint pin count and numbering coverage look structurally correct.
The largest possible manufacturing risk is the plated through-hole geometry: current footprint uses 0.95 mm drill / 1.425 mm pad, which may be too small if the official drawing requirement is really 1.02 mm hole / 1.55 mm pad min.
The symbol metadata quality needs cleanup because all terminals are effectively untyped/undefined.
I do not see evidence of a catastrophic pin-count mismatch, wrong row count, or wrong connector family.

If you want, I can next produce a concise fix list for this part project.
