The cable groups listed — RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907 — cover the common 50 Ohm flexible coax used in short-jump antenna leads and test equipment interconnects. LMR-195 is a lower-loss alternative to RG-58 that still fits the same crimp die family, so you're not locked into one cable type. ## Threaded Coupling and 500 Mating Cycles The threaded fastening type is standard TNC — a hand-tightened coupling nut. 500 mating cycles is the rated life. ## Gender Swap vs. Standard TNC The difference is the interface: the 031-5677 is RP-TNC with a female socket, so it mates with RP-TNC jacks (male pin), while the 031-2367-RFX is standard TNC and mates with standard TNC jacks (female socket). If your BOM calls for standard TNC, the 031-2367-RFX is the correct part; if it calls for reverse-polarity TNC, the 031-5677 is the one.","metaTitle":"Amphenol RF 031-5677 RP-TNC Plug, 50 Ohm, 11 GHz, Crimp","metaDescription":"Amphenol RF 031-5677 RP-TNC plug, female socket, 50 Ohm impedance, 11 GHz max frequency, crimp termination for RG-58/LMR-195.
