The 901-10762: The threaded fastening gives a vibration-resistant mate — the coupling nut torques down against the mating plug's threads, not a push-on latch. Gold body finish and gold-over-beryllium copper centre contact handle the 500 mating cycles without fretting.
This jack is built for 1.13 mm OD coaxial cable — the cable group is specified in the datasheet, and the shield termination is crimp, the centre contact is solder. That combination is typical for thin-diameter RF cables where the centre conductor is solid enough to solder without melting the dielectric.
The 901-10762 is the free-hanging in-line variant in the 901-10 series. Its bulkhead-mounted siblings — 901-10754 and 901-10768 — carry a 335 V rating versus the 166 V here, and they mount through a panel with a front-side nut. The voltage difference comes from the clearance between the centre contact and the grounded shell: the bulkhead version has a longer dielectric standoff. For a cable-to-cable assembly where no panel cutout exists, the 901-10762 is the correct choice; for a panel feedthrough, the 901-10754 is the direct swap.
