The TE Connectivity 5413515-9 is officially listed as Obsolete. This BNC jack is no longer in factory production and has no L* successor on record. For a new design or a long-term BOM, a parametric cross-shop against active 50 Ohm BNC jacks with board lock and similar frequency range is recommended.
It is a bulkhead-mount, right-angle through-hole part with a front-side nut for panel fixing. The bayonet lock delivers the quick-twist mate characteristic of the BNC interface — a quarter-turn locks the pair, no tool needed. The 1 GHz maximum frequency suits it for baseband video, RF test equipment, and telecom signal distribution up to the lower UHF band. Key features include a board lock for additional PCB retention, an integrated filter, and an isolated design.
The 1 GHz frequency ceiling means the connector maintains acceptable VSWR up to that point; beyond 1 GHz the geometry of the BNC interface typically degrades return loss. The 500 mating cycles reflect the gold-plated contact's wear life; beyond that, the plating may wear through and contact resistance can rise.
The right-angle through-hole solder tails terminate to the PCB — the board lock snaps into a plated hole and gets soldered, taking shear and vibration load off the signal pins. The dielectric material is polymethylpentene (PMP), a low-loss thermoplastic that holds the impedance tolerance.
