Product Introduction
The TE Connectivity 221198-1 is a Coaxicon-series BNC twinaxial jack with a hybrid contact arrangement — one female socket and one male pin in a single shell. It mounts through a panel bulkhead with a front-side nut and terminates via solder cups. The zinc body carries a nickel finish, and the center contacts are gold-plated brass and phosphor bronze. Rated for 500 V and 200 mating cycles, it operates from -55°C to 85°C. The non-constant impedance means this was designed for low-frequency twinaxial signal or power applications, not for controlled-impedance RF paths.
There is no listed direct replacement or successor order code. Buyers should expect to work with surplus or broker inventory for this part.
As a BNC-style twinaxial jack, it mates with standard BNC twinaxial plugs of the same shell configuration. The bayonet lock provides quick-connect retention. The hybrid contact arrangement (one socket, one pin) means the mating plug must have the complementary arrangement — one pin and one socket. The dielectric material is Polymethylpentene (PMP). No specific compatible cable types or mating part numbers are listed in the available documentation; verify the contact arrangement and shell dimensions against the mating half.
The connector uses a panel-mount, through-hole solder termination. The shield is terminated via a solder cup, and the center contacts are solder-cup style. The housing is natural and silver-colored zinc with nickel body finish.
