Part Data Review and Validation

Worked for 1 min 17 sec

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:

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.
