Product details

2.5 mm TRRS jack, SMT right-angle

The SJ2-25974B-SMT-TR is the 4-conductor (TRRS) member of CUI Devices' SJ2 phone jack family, accepting a 2.50 mm industry-standard plug. Rated 1 A at 12 VDC with gold-plated contacts, the jack mounts surface-mount right-angle and includes a single internal switch.

Switch count and conductor count across the SJ2 family

Within the SJ2-25 series, the SJ2-25974B-SMT-TR's 4-conductor, single-switch configuration sits between the 3-conductor, switchless SJ2-25103A-SMT-TR and the 4-conductor, dual-switch SJ2-25404D-SMT-TR — all share the same 2.50 mm mating diameter, 1 A rating, and SMT right-angle footprint.

Frequently asked questions

What is the closest functional second-source to SJ2-25974B-SMT-TR?

Within the SJ2-25 series, the SJ2-25404D-SMT-TR is a 4-conductor sibling with two internal switches instead of one — same 2.50 mm plug, same footprint, same current and voltage ratings.
