The bayonet lock gives a quick quarter-turn mate that holds against casual vibration, though it is not a threaded connector for high-shock environments. The body is brass with a silver finish — the silver provides good RF conductivity on the shield path, though it will tarnish over time in outdoor or humid storage. The dielectric is PTFE, which holds its electrical properties across the operating range of -30°C to 60°C.
Termination — Solder Center, Crimp Braid
This plug uses a solder contact for the center conductor and a crimp termination for the shield. The solder joint is the standard approach for the signal pin on RG-196 — it gives a reliable connection when done with the right iron temperature and flux. The shield crimp is what locks the braid mechanically and electrically; a proper crimp die matched to the RG-196 cable OD is essential. Free-hanging in-line mounting means this plug is intended for cable assembly, not panel mount.
Lifecycle and Sourcing — Last Buy Status
The BNC-P-196/U(40) is on Last Buy status. That means the manufacturer has stopped regular production, and the remaining stock in the channel is the final availability. There is no official successor order code listed for this part. For a BOM line that requires this exact Hirose part number, the only path is to source from the remaining distributor inventory or the surplus market.
