That means the manufacturer is not actively promoting it for new projects, though it remains available for existing designs through the supply channel. For a new design, look at the standard-production BNC plugs in the same 031-32 base series; the RFX suffix signals a specific variant that may not have a direct one-to-one drop-in, so check the cable group and interface dimensions against your assembly before committing. The 031-326-RFX is listed for RG-55, 142A, 223, and 400 cables — all 50 Ohm types with a similar dielectric diameter and braid coverage. It does not list RG-58, which is a common 50 Ohm cable but uses a smaller dielectric (0.116 in vs 0.150 in for RG-223). If you need an RG-58-compatible BNC plug, you want a different part in the 031-32 base family. The dielectric spacer is polyoxymethylene (POM) acetal, which holds its shape under the crimp force and gives consistent 50 Ohm impedance through the joint.","metaTitle":"031-326-RFX BNC Plug, 50 Ohm, 4 GHz, NRND","metaDescription":"Amphenol 031-326-RFX BNC plug, male pin, 50 Ohm, 4 GHz, 0.2 dB insertion loss, 500 mating cycles.
