MMCX Plug for RG-174/188/316 — Molex 0734151251
The Molex 0734151251 is a 50 Ohm MMCX plug, male pin, designed for field-termination on RG-174, RG-188, and RG-316 cable. It ships as a kit with the connector body, one contact, and one ferrule, so you don't have to chase separate BOM lines for a single cable end. The snap-on coupling locks with an audible click — no threads to cross, no torque spec to hit — which makes it fast to mate in tight panel spaces or harness assemblies where you're building multiple pigtails. Rated to 6 GHz with a 170 V voltage rating, this plug handles the common RF bands for short-jump interconnects inside enclosures — think antenna feeds, module-to-board jumpers, or test-point cables where the MMCX's smaller footprint beats an SMA. The gold-plated brass body and gold center contact give it 500 mating cycles of reliable service before the plating wear starts to shift contact resistance.
For RG-174 and RG-316, the crimp die size is standard — no special tooling beyond a common hex crimper for the ferrule OD. The PTFE dielectric in the connector body matches the cable's dielectric, keeping the 50 Ohm impedance consistent through the joint. Strip lengths follow the standard MMCX prep for these cable groups; the ferrule seats over the jacket after the braid is folded back.
