For a BOM that calls this part, the options are a last-time buy through surplus or broker channels, or a cross-reference to a functionally equivalent dual-port 75 Ohm mini BNC jack from another manufacturer — but that requires verifying the mounting footprint (panel cutout, PCB hole pattern, right-angle orientation, front-side nut). ## Termination and Mounting — Solder, Not Crimp The shield termination is a solder cup or tab for the cable braid; the center contact is a solder cup for the signal wire. This is a field-solder operation — no crimp tool required, but a soldering iron and heat-shrink are part of the assembly process. The connector mounts through a panel hole and is secured with a front-side nut, with the right-angle PCB tails soldered into the board after the nut is tightened.","metaTitle":"TE Connectivity 1274684-1, Dual-Port Mini BNC Jack, 75 Ohm","metaDescription":"TE 1274684-1 dual-port 75 Ohm mini BNC jack, 2 GHz, 300 V, 500 mating cycles.
