Part Data Review and Datasheet Search

flux

Review complete.
  • 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.
