50 Ohm BNC Jack with Internal Switch — 4 GHz, Through-Hole
The 6274314-1: It carries a 500 V rating and is built for through-hole solder termination to the PCB, with the shield terminated by solder as well. What sets this jack apart is the internal switch feature: when no plug is mated, the switch changes the signal path, useful for self-terminating or monitoring circuits where the connector itself acts as a signal-routing element.
Obsolete — Sourced to Order for Legacy BOMs
The 6274314-1 is listed as Obsolete. There is no official replacement order code on record from TE Connectivity. Confirm the switching logic and footprint before specifying an alternative.
500 Mating Cycles, Silver-Plated Contact, Wide Temp Range
Rated for 500 mating cycles — standard for a BNC in bench and rack use, not a high-cycle field connector but adequate for periodic reconnection in a test setup. The center contact is phosphor bronze with silver plating, giving low contact resistance and good RF conductivity through the signal path. The zinc body with tin finish and the polyphenylene oxide (PPO) dielectric hold up across -55°C to 85°C, so this jack can live in an outdoor telecom cabinet or an unheated industrial enclosure without issue. The single-port, Bulk packaging means it ships loose — no tape-and-reel, no pick-and-place handling.
