QMA Snap-On Plug for RG-174/188/316
The 1408333-1: The snap-on fastening gives a quick, tool-less mate to any standard QMA jack — no coupling nut to turn, which saves time in dense panel layouts. Impedance is held at 50 Ohm across the band up to 6 GHz, with insertion loss spec'd at 0.25 dB. The center contact is gold-plated brass, soldered to the cable center conductor; the shield is crimped through the nickel-plated brass body. The kit ships three pieces: the connector body, the contact, and the ferrule.
It is not in active factory production. There is no official TE replacement order code on record for the 1408333-1. If you need a QMA plug for the same cable groups, the closest active alternative is a parametric search on 50 Ohm QMA plugs for RG-174/188/316; verify the mating half and board footprint before substituting.
Cable Prep and Termination
The 1408333-1 terminates RG-174, RG-188, or RG-316 cable. The snap-on mating interface engages with a standard QMA jack — the retention is positive but releases with a straight pull.
