SMP right-angle jack for RG-174/188/316 coax
The Molex 0734155030 is an SMP-series jack (female socket) from the 73415 family, designed for free-hanging, right-angle termination on RG-174, RG-188, and RG-316 coaxial cables. The connector ships as a three-piece kit: the SMP jack body, an end cap, and a ferrule. The end cap and ferrule are crimped over the cable braid and jacket during assembly — no separate hardware sourcing required.
Key RF and mechanical specs
The 50 Ohm impedance and 40 GHz upper band limit define the signal path — this is a true SMP interface, not a reduced-bandwidth knock-off. The snap-on fastening gives a quick, positive lock without threads, which is standard for SMP blind-mate or board-to-board RF connections where repeated mating cycles are expected. Contact termination is solder for the centre pin, and shield termination is crimp. The centre contact is beryllium copper with gold plating; the body is gold-plated brass. Dielectric is PTFE, which keeps insertion loss stable across the -65°C to 155°C operating range. Voltage rating is 335 V, which is typical for an SMP connector at this impedance and frequency — the limiting factor is the air gap at the interface, not the dielectric.
Cable compatibility and field assembly
This jack is explicitly listed for RG-174, RG-188, and RG-316 cables — all 50 Ohm, ~0.1-inch-diameter coax types common in RF patch cords and internal equipment wiring. The right-angle body keeps the cable routed parallel to the mounting surface, which saves height in enclosures where a straight plug would hit the lid. The end cap snaps over the ferrule to seal the termination.
