Part Data Review and Validation


Review complete. The part already has the official Kycon datasheet URL set, so no Datasheet property update was needed: https://www.kycon.com/Pub_Eng_Draw/KPJX-4S-S.pdf
Key specs found:
  • MPN: KPJX-4S-S
  • Manufacturer: Kycon
  • Description: DC Power Jack, 4-position, shielded, RoHS compliant
  • Contact rating: 7.5 A max per pin @ 48 VDC
  • Contact resistance: 30 mΩ max
  • Insulation resistance: 50 MΩ min @ 250 VDC
  • Dielectric withstand: 500 VAC RMS for 1 min
  • Operating temperature: -40 °C to +75 °C
  • Body: PBT thermoplastic, UL94V-0
  • Contacts: brass, tin plated
  • Recommended mating plug: Kycon KPPX plug
Cross-check results:
  • Project metadata matches the datasheet for manufacturer, MPN, part type, and datasheet URL.
  • Schematic exposes 9 terminals: pins 1–4 plus MH1–MH5.
  • Footprint includes pads 1–4 plus MH1–MH7, so there is a mismatch: MH6 and MH7 exist in the footprint but not in the schematic symbol.
  • Pin descriptions are currently not populated beyond generic/unspecified terminal properties.
  • Datasheet shows 4 electrical positions and multiple mechanical/shield/mount holes, so the electrical pin count is correct, but the mechanical pad representation needs cleanup/confirmation.
Flagged mismatches:
  • Footprint/symbol mismatch: footprint has MH6 and MH7 that are not represented in the schematic.
  • Pin metadata incomplete: pins are “Unspecified” and lack datasheet-based descriptions such as power contacts, shield tabs, or mechanical holes.
  • Description nuance: project description says “Circular Connector Jack,” while datasheet calls it a “DC Power Jack, 4 Position, Shielded.” This is probably acceptable but could be made more exact.
