I reviewed the part project and the datasheet is already present, so step 2 did not require a web search or property update. The official PDF already available on the project is: Datasheet

Datasheet summary

General

Parameter	Value
Product family	WR-FPC Zero Insertion Force Connectors - 0.50 mm
Style	SMT, horizontal, bottom contact, low profile, ZIF
Pin count	30
Pitch	0.50 mm
Packaging	Tape and reel
Lifecycle	Production active

Withstanding voltage	250 V AC for 1 min
Contact resistance	30 mΩ max
Insulation resistance	100 MΩ min

Absolute maximum ratings

Result	Notes
No explicit “Absolute Maximum Ratings” table found	The retrieved datasheet content exposes electrical/operating data, but not a separate absolute max section. For this connector, the practical limits appear to be the published rated current, working voltage, and dielectric withstand figures above.

Recommended operating conditions

Parameter	Value
Operating temperature	-25 °C to +85 °C

Pin descriptions

Result	Notes
No per-pin functional description table found	The datasheet identifies a 30-pin connector and shows the mating/contact geometry and land pattern orientation, but does not assign signal names or unique electrical functions to pins 1-30.
Mechanical pads	2 solder tabs / mounting pads are shown

Mechanical / package dimensions

Parameter	Value
Overall length	20.7 mm
Max height	2.0 mm max
Mounting style	Horizontal SMT
Contact style	Bottom contact
Orientation marker	“1 End” indicated in drawing

Cross-check: symbol and footprint vs datasheet

What matches

Check	Result	Notes
Pin count	Pass	Symbol has 30 signal contacts; datasheet says 30 pins
Mechanical pads	Pass	Symbol and footprint both include 2 mounting pads
Pitch	Pass	Footprint pads are placed at 0.50 mm spacing, consistent with datasheet
Mount/style	Pass	Footprint is SMT and horizontal, matching datasheet
Bottom-contact type	Likely pass	Part metadata matches the datasheet family and style

Risks / mismatches to flag

Issue	Severity	Why it matters
No explicit per-pin datasheet table	Low	For this connector family, all signal pins are usually equivalent, so this is not necessarily wrong, but it means numbering must be validated from the mechanical drawing rather than a pin table
Orientation / pin-1 verification not yet proven from imported geometry text alone	High	The footprint includes a pin-1 silkscreen marker and the datasheet mentions “1 End”, but I cannot prove from the extracted text alone that the imported pad numbering direction exactly matches the Würth drawing. A reversed numbering scheme would cause cable miswiring or total board failure
Recommended land pattern not explicitly retrieved as dimensioned table	Medium	The footprint geometry looks internally consistent, but without a full dimensioned land-pattern extraction from the PDF, pad width, toe/heel length, and mounting-tab geometry are not fully confirmed against Würth’s recommendation
Current rating discrepancy in retrieved sources	Medium	One datasheet extraction returned 0.4 A, while another source snippet returned 0.5 A. This should be resolved against the exact PDF table before using the part near its current limit
Symbol pin types all set to “Unspecified”	Low	Not a manufacturing issue by itself, but it weakens ERC behavior in designs using this part

Bottom-line assessment

Area	Status
MPN / description consistency	Good
Symbol contact count	Good
Footprint contact count	Good
Footprint style / package family	Good
Manufacturing-risk confidence	Moderate, not final
Biggest remaining risk	Pin-1 orientation / numbering direction

Most important conclusion

The part project looks mostly consistent with the Würth connector metadata and general datasheet information, but the one issue I would treat as must-verify before trusting this for production is the pin-1 orientation and numbering direction of the footprint relative to the datasheet’s bottom-contact horizontal drawing. That is the mismatch most likely to cause a real board failure.

If you want, I can next do a stricter mechanical verification pass against the PDF drawing and call out the exact pad-numbering direction risk in detail.
