MCX Snap-On Plug for RG-174/188/316 — 50 Ohm, 6 GHz
It is a 50 Ohm connector rated to 6 GHz, with a snap-on fastening that gives a positive lock and 500 mating cycles. The body is brass with gold finish, the centre contact is brass with gold plating, and the dielectric is PTFE. The shield is terminated by crimp, the centre contact by solder. This is a single-port connector supplied as a kit: one connector body, one contact, and one ferrule.
This plug is built for RG-174, RG-188, and RG-316 cables — the three most common 50 Ohm flexible coax types in the 0.100-inch diameter range. The crimp shield termination and solder centre contact are standard for these cables; the ferrule compresses over the braid, and the centre conductor solders into the pin. The kit includes the connector body, a pre-loaded contact, and the crimp ferrule, so no separate terminal order is needed for a single assembly.
No direct replacement order code is listed in the lifecycle record. If the design can accept a parametric alternative, a current-production MCX plug from the same series or a compatible RF connector family should be evaluated; the manufacturer's documentation for the Greenpar series may list a recommended successor.
RF Performance and Operating Range
Insertion loss is 0.1 dB, and the voltage rating is 335 V. The gold-over-brass body and centre contact resist corrosion through repeated matings.
