This plug is sized for Belden 9913, 9914, and LMR-400 cable groups. The center contact crimps onto the pin, and the shield termination crimps over the braid through the supplied ferrule. ## Lifecycle: NRND — Plan the Cross The 031-5998-RFX carries a Not Recommended for New Design (NRND) status. That means it is still available through existing stock and last-time-buy channels, but the manufacturer will not support it in new projects. No official replacement part number is listed by Amphenol RF, so any cross must match the BNC interface, 50-ohm impedance, 4 GHz bandwidth, and the same crimp-on cable group. ## 500 Mating Cycles in the Field The nickel body finish resists corrosion in shop-floor or outdoor cabinet environments.","metaTitle":"031-5998-RFX BNC Plug Kit, 50 Ohm, 4 GHz, NRND","metaDescription":"Amphenol RF 031-5998-RFX BNC plug kit, 50 Ohm, 4 GHz, 500 mating cycles.
