Part Datasheet Review and Cross-Check

flux

Review complete
The part already has a datasheet URL set, so step 2 was not needed. I used the existing PDF: Datasheet

4) Cross-check: symbol and footprint vs datasheet Cross-check results

Table

CheckStatusRisk
Terminal countPassProject has 5 electrical terminals, matching datasheet terminal set
Pin numberingFailDatasheet uses 3, 4, 5, 6, 7 for electrical terminals, but project uses 1, 2, 3, 10, 11
Pin namingFailProject symbol terminals are unnamed; datasheet defines Sleeve / Shunt-B / Shunt-A / Ring / Tip
Pin typingWarningAll pins are Unspecified; not fatal for manufacturing, but poor for reuse/clarity
Functional mappingUnknown / high riskNo verified one-to-one mapping from project pins to datasheet functions
Footprint pad countPass5 pads present, consistent with electrical terminal count
Footprint geometryNot fully verifiable from extracted textDatasheet has a PCB layout drawing, but exact hole locations/drills were not machine-extracted here
Critical issues to flag High-risk mismatch

Table

IssueWhy it matters
The project pin numbers do not match the datasheet terminal numberingThis can cause incorrect schematic-to-footprint pin mapping, wrong net assignment, and a board that routes Tip/Ring/Sleeve/shunt contacts incorrectly
Symbol pins are unnamedA user cannot reliably tell which terminal is Tip, Ring, Sleeve, or shunt contact
Switched-contact jack behavior is not captured explicitlyMiswiring the shunt terminals can break jack-detect or default-signal routing behavior
Bottom line

Table

ConclusionResult
Safe to manufacture as-is?Not yet
Main reasonThe pin-numbering and functional mapping are not aligned to the datasheet
Most likely failure modeCorrect footprint count but wrong electrical connectivity/order
Recommended correction target
The final part should expose five clearly named pins mapped to the datasheet functions:
  • Sleeve
  • Shunt Terminal-B
  • Shunt Terminal-A
  • Ring
  • Tip
And the symbol/footprint pin numbers should match the datasheet numbering exactly: 3, 4, 5, 6, 7.
