50 Ohm BNC plug for 5C-2V / 5D-2V coax — 500 MHz ceiling
The Hirose BNC-P-5DV-SA(40) is a 50 Ohm BNC plug, male pin, designed for field termination onto 5C-2V and 5D-2V coaxial cable. Rated to 500 MHz maximum, it covers standard video, RF instrumentation, and baseband data links — the 50 Ohm impedance keeps it in the RF/video camp rather than the 75 Ohm broadcast-video branch. The silver-plated brass body and centre contact give a corrosion-resistant RF path, and the PTFE dielectric holds the impedance steady through the operating range.
Cable fit — 5C-2V and 5D-2V only
This plug is built for 5C-2V and 5D-2V cable groups — Japanese/Asian standard coax with a nominal impedance around 50 Ohm. It will not correctly terminate RG59 (75 Ohm) or RG58 (50 Ohm but smaller diameter) without a cable-group adapter. If your harness calls for a different cable family, this is not the right plug.
1000 mating cycles — field-service rated
The bayonet lock gives a quarter-turn fast mate — no coupling nut to spin. Silver plating on the centre contact and body finish handles the cycle count without galling, though silver tarnishes over time in sulphurous environments; for corrosive duty a gold-plated BNC would be a better fit.
Last Buy — source before the window closes
Hirose has marked the BNC-P-5DV-SA(40) as Last Buy. That means the production end date is set — once the remaining factory stock is exhausted, this order code will not be manufactured again. For BOM lines that call this exact plug, the procurement path is to secure the remaining inventory through independent distribution now, quoted per RFQ. If you need a long-term supply, a parametric search for a 50 Ohm BNC plug with a clamp/solder termination for 5C-2V cable is the next step — but no direct cross-reference is published.
