Part Metadata Review and Update

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

Read schematic.

I reviewed and updated the SJ1-3524N part metadata, set the official Same Sky datasheet URL, and cross-checked the terminals against the datasheet: pins 1 Sleeve, 2 Tip, 3 Ring, and 10 Tip Switch are present; pin 11 is correctly absent for this variant. I flagged two follow-ups: the terminal display labels still read back as placeholder-style IDs, and the footprint geometry could not be fully dimension-verified from the available layout readback. Full details are in SJ1-3524N Part Review.

Note: I attempted to rename the terminal display labels from placeholders to Sleeve/Tip/Ring/Tip Switch, but the schematic readback still shows placeholder-style ~::... identifiers. The functional terminal properties are correct; if the visible symbol labels still appear generic in the editor, this may require manual symbol asset editing or a part-generation refresh.
Footprint / asset audit
Available assets:
  • CUI_SJ1-3524N.kicad_mod marked as footprint
  • SJ1-3524N Symbol.svg marked as default symbol / thumbnail
  • SJ1-3524N.step marked as 3D model
Layout readback shows:
  • 4 electrical pad nodes associated with terminal UIDs, matching electrical pins 1, 2, 3, and 10
  • 5 additional mount/mechanical pad nodes
  • Footprint asset name is specifically CUI_SJ1-3524N.kicad_mod
Datasheet footprint notes:
  • The recommended PCB layout is a common SJ1-352XN family footprint.
  • For SJ1-3524N, terminal 11 is not populated.
  • The jack mouth / connector edge must face the PCB connector edge.
  • Recommended layout includes round holes and slotted terminal holes; exact geometry could not be fully verified from the layout tool readback because pad coordinates/dimensions were not exposed in the returned data.
Mismatches / risks flagged
  1. Terminal visible labels may still be placeholders: The schematic terminal properties are correct, but readback still shows ~::... style identifiers instead of human-readable terminal designators.
  2. Footprint geometry not fully verifiable from tool readback: Pad count looks plausible, and the asset name matches SJ1-3524N, but I could not confirm every hole/slot dimension or pad coordinate from the available layout data.
  3. Pin 11 correctly absent: No pin 11 terminal is present, which is correct for SJ1-3524N.
Overall result
The part metadata and terminal pin properties now match the official Same Sky / CUI Devices SJ1-3524N datasheet at the electrical-pin level. No electrical pin-count mismatch was found. The main remaining check is visual/mechanical: confirm in the editor that the symbol labels render as intended and that the jack mouth/connector edge orientation in the footprint matches the datasheet drawing.
