Product details

SMA plug for RG-174-family cable, now obsolete

The 1056443-1: It is designed for use with RG-174, RG-179, RG-187, RG-188, and RG-316 coaxial cables, using a crimp shield termination and a solder centre contact. The threaded coupling nut provides a secure, vibration-resistant mate to any standard SMA jack.

Cable prep and termination checklist

This connector accepts RG-174, RG-179, RG-187, RG-188, and RG-316 cable. The stainless steel body resists corrosion in field-service environments. With 500 mating cycles on the spec, it handles repeated connect-disconnect in test or portable equipment without degrading the RF interface.

Sourcing an obsolete SMA plug

For a new design, a parametric search on SMA plugs with the same cable group, 50 Ohm impedance, and 12.4 GHz ceiling will surface current-production alternatives; verify the interface dimensions and cable-prep method before substituting.
