PJ-313D
HanElectricity
Needs validationmedium risk
PJ-313D is an SMD audio jack candidate but needs pinout and footprint review.
Best Alternatives to PJ-320D
PJ-320D is a 4-pin SMD 3.5mm audio jack. Current alternatives need FAE review because pinout evidence is missing.
AI replacement insight
Electrical riskmedium
Some candidates have lower ratings.
Package riskmedium
SMD class matches only on kept parts.
Firmware risklow
Passive connector; no firmware.
Sourcing riskmedium
Lifecycle data is incomplete.
Can it be replaced directly?
No pin-compatible replacement is verified from the supplied evidence.
Best replacement path
Start with PJ-313D only if a 3-pin SMD jack can satisfy the circuit.
Main risk
Pinout and footprint mismatch.
