Product details

BNC Plug for RG-174/188/316 — 50 Ohm, Crimp Termination

The centre contact is gold-plated brass; the body is zinc with a nickel finish.

This plug is built for RG-174 and RG-316 cable — two common small-diameter 50 Ohm coax types. The crimp termination for both centre pin and braid means a consistent, repeatable termination with the correct hex die set.

No official replacement order code is on record. For a BOM that needs this exact TE part number, the channel is surplus and broker stock; expect to confirm quantity and lead time per request.
