Product details

5-conductor TRRRS phone jack, 3.50 mm

The SJ2-3544A-SMT-TR is the 5-conductor (TRRRS) member of CUI Devices' SJ2 phone jack line, accepting a 3.50 mm industry-recognized mini plug. Gold-plated contacts rated 1 A at 12 VDC. Surface-mount right-angle orientation with solder termination; unshielded housing in black polyamide (PA10T).

4 vs 5 conductors — signal count decision

The 5-conductor SJ2-3544A-SMT-TR carries a TRRRS plug for balanced audio or multi-channel signals; the SJ2-3574A-SMT-TR is a 4-conductor (TRRS) variant at the same 3.50 mm diameter, same pitch and footprint.

Frequently asked questions

What compliance documentation does CUI Devices provide for SJ2-3544A-SMT-TR?

The part is ROHS3 Compliant per the manufacturer.

Will SJ2-3544A-SMT-TR drop into a panel that was specified around SJ2-35825A-SMT-TR without rewiring?

Both are 5-conductor, 3.50 mm, female, SMT right-angle jacks with identical mating depth and body dimensions — the SJ2-35825A-SMT-TR adds a board guide feature. The footprint is the same; the board guide may require a matching keep-out.
