Schematic symbol / terminal audit
Current schematic has 4 terminal elements, matching the SJ1-3524N electrical pin count.
Table
| Datasheet pin | Datasheet function | Flux terminal found | Status |
|---|---|---|---|
| 1 | Sleeve | Pin Number 1, Passive, Pin Description Sleeve contact | OK |
| 2 | Tip | Pin Number 2, Passive, Pin Description Tip contact | OK |
| 3 | Ring | Pin Number 3, Passive, Pin Description Ring contact | OK |
| 10 | Tip Switch | Pin Number 10, Passive, Pin Description Tip switch | OK |
| 11 | Not populated for SJ1-3524N | No terminal found | OK |
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_modmarked as footprintSJ1-3524N Symbol.svgmarked as default symbol / thumbnailSJ1-3524N.stepmarked 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
- 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. - 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.
- 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.
