Part Audit

cherepanyadima

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.

I’ll audit the part metadata and existing assets, locate the official CUI Devices datasheet if needed, update the Datasheet property, then cross-check symbol pins and footprint geometry against the manufacturer drawing.

Part Audit Scope
Audit of published part SJ2-35813B-SMT-TR against the official Same Sky (formerly CUI Devices) datasheet.
Existing Part Information Key Datasheet Specifications
  • 3.5 mm stereo audio jack
  • Right-angle / horizontal, surface mount
  • Three conductors
  • One internal tip switch
  • Tape-and-reel packaging
  • Rated input voltage: 12 Vdc
  • Rated input current: 1 A

Audit complete; details are in Part Audit. The four pad numbers and footprint geometry generally match the official datasheet, but the description, manufacturer/package metadata, and functional pin descriptions are incomplete; the Ø1.5 mm locating holes sit at the datasheet’s maximum tolerance.
Blocked: The official datasheet is https://www.sameskydevices.com/product/resource/sj2-3581x-smt.pdf, but the available editor did not expose a safe part-level Datasheet URL property, so I could not write it automatically.

Pin and Symbol Cross-Check

Table

TerminalDatasheet functionExisting symbolResult
1SleevePin number 1, passive, no functional name/descriptionElectrically numbered correctly; description missing
2TipPin number 2, passive, no functional name/descriptionElectrically numbered correctly; description missing
3RingPin number 3, passive, no functional name/descriptionElectrically numbered correctly; description missing
10Tip switchPin number 10, passive, no functional name/descriptionElectrically numbered correctly; description missing
The symbol has the correct four terminal numbers and passive electrical types. However, it does not expose the functional pin names or pin descriptions. Terminal 10 should explicitly identify the switched tip contact. The datasheet schematic indicates the tip switch is closed to terminal 2 with no plug inserted and opens when a plug is inserted.
Footprint Cross-Check
Existing footprint contents:
  • Four SMT pads: 1, 2, 3, 10
  • Two non-plated locating holes
  • Pad 1: 1.5 × 2.65 mm at (-3.75, 3.325) mm in the imported KiCad footprint datum
  • Pad 2: 1.5 × 2.85 mm at (3.05, 3.225) mm
  • Pad 3: 1.5 × 2.65 mm at (-0.95, -3.525) mm
  • Pad 10: 1.5 × 2.65 mm at (4.85, -3.525) mm
  • Locating holes: Ø1.5 mm, 6.0 mm center-to-center
  • Fabrication body outline: 11.5 × 6.0 mm, with front barrel extension
  • 3D STEP model attached
Cross-check findings:
  • Electrical pad numbering and count match the datasheet.
  • Two locating holes and their 6.0 mm spacing match the recommended layout.
  • Ø1.5 mm holes are at the upper limit of the datasheet's Ø1.4 +0.1/-0 recommendation; this is acceptable nominally but leaves no additional diameter margin.
  • Body outline dimensions align with the 11.5 × 6.0 mm package envelope.
  • No confirmed pad-position mismatch was found from the dimension data that could be reliably extracted. The exact pad land geometry should still be visually checked against page 2 of the current datasheet before production because the manufacturer notes a 2022 reengineering revision and does not currently provide an official downloadable PCB footprint on its resource page.
Mismatches and Risks
  1. Missing Datasheet URL property — official URL found, but the available project mutation interface did not expose a safe part-level Datasheet URL field for this published part project. It was therefore not written automatically.
  2. Description mismatch — current description is not a meaningful product description.
  3. Missing manufacturer property — should be Same Sky (formerly CUI Devices).
  4. Missing package/category detail — should identify a 3.5 mm right-angle horizontal SMT audio jack, 3 conductors, tip switch.
  5. Missing functional pin descriptions — terminals are numbered correctly but should be labeled Sleeve, Tip, Ring, and Tip Switch.
  6. Hole diameter is maximum tolerance — Ø1.5 mm equals the maximum recommended finished opening; consider using the manufacturer nominal Ø1.4 mm if fabrication tolerance and locating fit require tighter registration.
