Product details

2.5 mm stereo jack, SMT right-angle

The SJ1-2534-SMT-TR is the single-switch member of CUI Devices' SJ1 2.5 mm phone jack family, accepting a standard 2.50 mm (3/32") stereo plug. Rated 1 A at 12 VDC with gold-plated contacts on a copper alloy base, the jack is housed in a PA6T body rated -25°C to 85°C.

Switch configuration across the SJ1-25 series

Within the SJ1-25 sub-series the SJ1-2534-SMT-TR (single switch, 4 contacts) sits between the SJ1-2533-SMT-TR (no switch, 3 contacts) and the SJ1-2535-SMT-TR (two switches, 5 contacts) — all share the same 2.50 mm mating diameter, 1 A rating, and SMT right-angle footprint.

Frequently asked questions

What compliance documentation does CUI Devices provide for SJ1-2534-SMT-TR?

The part is listed as ROHS3 Compliant. No UL or IEC certification is cited in the available records.

Will SJ1-2534-SMT-TR drop into a board that was specified around SJ1-2533-SMT-TR without rewiring?

The footprint and mating diameter are identical across the SJ1-25 sub-series, but the SJ1-2534-SMT-TR adds a single internal switch and a fourth contact (tip, ring, sleeve, plus switch). The switch contact requires an additional PCB trace compared to the no-switch SJ1-2533-SMT-TR.
