Current part data: 40 schematic terminals, all passive, pin numbers 1–40 present.
Footprint: 40 SMD signal pads plus shield/mechanical pads; signal pads are ~0.70 mm × 2.50 mm, arranged in two rows with ~0.90 mm pitch.
Project-level metadata is incomplete: Datasheet, Manufacturer Name, and Part Type are missing.
I searched for an official Amphenol datasheet using the available clues: Amphenol, “X3”, 7.80 mm, 40 pins/pads, and the observed footprint geometry.
I found some Amphenol connector candidates, but none matched the actual 40-pad footprint confidently enough to update the Datasheet URL.
Flagged mismatches / issues:
No reliable MPN is set, so the datasheet cannot be uniquely identified.
No official datasheet URL is set.
No manufacturer name or part type is set at project level.
Symbol pin numbering 1–40 is internally complete, but pin descriptions are generic/missing.
Footprint geometry cannot be verified against datasheet until the exact Amphenol MPN is confirmed.
Next best step: provide the exact Amphenol MPN or a distributor/product link, and I can update the Datasheet property and perform a definitive symbol/footprint/pin-description cross-check.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
