The 901-10756: It's a bulkhead-mount with a front-side nut, threaded fastening, and a gold-plated brass body. It's an active-production part — no obsolescence concern for new builds.
The 335 V rating is for the RF carrier voltage, not a DC power bus; it's fine for most signal-level coax runs. The 500 mating cycles, backed by gold-on-gold contacts, mean it can handle repeated connect/disconnect in a lab or field-service role without the contact resistance drifting.
Cable and Termination Details
This jack is specced for 1.37mm coaxial cable — the crimp shield termination and solder center contact match that diameter. If you're replacing a failed connector on a 1.37mm coax assembly, this is a direct fit. The bulkhead mount with a front-side nut lets you panel-mount it with the jack body on the outside and the cable exit inside the enclosure.
