Product details

Termination and assembly

The SJ1-3554NG is a 3-conductor (TRS) phone jack from the CUI Devices SJ1 series, accepting a standard 3.50 mm mini plug. It terminates via kinked pins for through-hole right-angle soldering, with tin-plated brass and copper alloy contacts rated 1 A at 12 VDC.

Switch count and signal routing

This jack incorporates a single internal switch, which closes or opens the signal path when the plug is inserted. For applications needing two switched circuits, the SJ1-3555NG and SJ1-3545N carry two switches while sharing the same 3.50 mm mating diameter, 1 A rating, and kinked-pin termination.

Frequently asked questions

Will SJ1-3554NG drop into a panel specified around SJ1-3555NG without rewiring?

The SJ1-3554NG and SJ1-3555NG share the same 3.50 mm mating diameter, 1 A rating, 12 VDC voltage, and kinked-pin termination. The key difference is the internal switch count: single switch on the SJ1-3554NG versus two switches on the SJ1-3555NG. If the circuit relies on the second switch, the SJ1-3554NG will not function as a drop-in.
