The nickel-plated zinc die-cast body and gold-plated brass centre contact are standard for a clean signal path up to 2 GHz. The 75 Ohm impedance is the headline here — this is not a 50 Ohm BNC. Mating a 75 Ohm jack to a 50 Ohm plug creates a 25 % impedance mismatch that reflects signal at the interface, killing return loss above a few MHz. Stick with 75 Ohm cable and 75 Ohm mating plugs for video or data paths. The 2 GHz max frequency is the practical ceiling; above that the connector geometry starts to radiate. 500 mating cycles is standard for a bayonet-lock BNC — the coupling nut wears the detent over time, but for a panel jack that sees occasional reconnects in test or distribution gear it's fine. The shield terminates by soldering to the body — no crimp ferrule. The dielectric is polyethylene, which gives a stable 75 Ohm line through the interface. The board guide and isolated features help align the part during assembly and keep the signal path clean. ## Sourcing reality — obsolete part No official successor order code is on record. If you're open to a parametric alternative, a 75 Ohm BNC from the same series with a different mounting or plating may be available; check the 1634624 base number for active siblings.","metaTitle":"TE 1-1634624-0 BNC Jack, 75 Ohm, 2 GHz, Obsolete","metaDescription":"TE Connectivity 1-1634624-0 BNC jack, female socket, 75 Ohm impedance, 2 GHz max, 500 mating cycles, nickel body, obsolete.
