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.","metaTitle":"031-6872 Amphenol RF TNC Plug, LMR-400, 50 Ohm, 8 GHz","metaDescription":"031-6872 Amphenol RF TNC plug, male pin, 50 Ohm, 8 GHz max, for LMR-400 cable.
