There is no listed direct replacement in the evidence, so you're looking at either a last-time-buy pull from surplus or a form-fit-function cross to a current-production BNC plug. The 50 Ohm impedance, 4 GHz bandwidth, crimp termination, and RG-179/187 cable compatibility are the parameters a substitute must match. If you have a BOM line with this number, source it now against an RFQ — availability shrinks as stock clears. ## RF Performance — What the 50 Ohm and 4 GHz Rating Mean The 4 GHz maximum frequency means this plug handles signals up into the low microwave band; above that, the BNC interface geometry starts to introduce mode conversion and higher loss. The 0.2 dB insertion loss is typical for a mated pair at lower frequencies; expect it to rise toward the 4 GHz limit. For a field-serviceable crimp connector, the 500 mating cycles are generous — the gold-plated center contact and nickel body finish resist corrosion through repeated connects. This plug is built for RG-179 and RG-187 cables — both are 50 Ohm, 0.100-inch-diameter coax types common in test leads and internal equipment wiring. The shield terminates via crimp (the ferrule compresses over the braid), and the center contact also crimps onto the signal conductor. No soldering required, which speeds up harness assembly and gives consistent pull-off strength.","metaTitle":"TE 2-227079-0 BNC Plug, 50 Ohm, 4 GHz, Obsolete","metaDescription":"TE 2-227079-0 BNC plug, male pin, 50 Ohm, 4 GHz, 0.2 dB loss.
