Product details

50 Ohm TNC Plug for LMR-400 — 8 GHz, 500 Mating Cycles

The center contact is gold-plated brass, soldered to the signal conductor; the shield is crimped to the nickel-plated brass body.

This plug is specified for LMR-400, a low-loss 0.405-inch diameter coaxial cable. The threaded coupling nut provides vibration-resistant mating — the TNC interface mates with any standard TNC jack (female).

No official second-source or successor cross-reference exists.

Selection Against the 031-6683-EE Sibling

The critical difference is the cable group: the 031-6872 is built for LMR-400, while the 031-6683-EE is built for the smaller LMR-240. The 031-6872 also uses a brass center contact versus the beryllium copper contact in the 031-6683-EE. Pick by cable diameter first — the ferrule and pin dimensions are specific to the cable jacket and dielectric OD.
