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.","metaTitle":"TE 1408333-1 QMA Plug, 50 Ohm, 6 GHz, RG-174/188/316","metaDescription":"TE Connectivity 1408333-1 QMA snap-on plug, 50 Ohm, 6 GHz max, for RG-174/188/316 cable.
