Obsolete — Sourcing Options
The 1051665-1 is officially obsolete per TE Connectivity's lifecycle status. No direct replacement is listed in the official record. If you need a pin-compatible alternative, check the RG-174 SMA plug family from other manufacturers; the 50 Ohm impedance, 12.4 GHz frequency ceiling, and threaded coupling are standard interface parameters.
SMA Plug for RG-174 — Kit Contents and Fit
This is a complete assembly kit, not just a bare connector. The package includes 8 pieces: the SMA plug body (male pin), a bushing, a centre contact, a heat shrink tube, an insulator, a coupling nut, and two sleeves. Everything needed to terminate RG-174 cable is in the box — no separate crimp ferrule or boot to order. The shield is crimped; the centre contact is soldered. The threaded coupling nut provides a vibration-resistant mate, and the stainless steel body gives good corrosion resistance in outdoor or industrial environments.
Rated at 50 Ohms nominal impedance with a maximum operating frequency of 12.4 GHz. The PTFE dielectric keeps insertion loss stable across the band, and the gold-plated brass centre contact maintains low contact resistance through 500 mating cycles — well above the typical 200-cycle spec for standard SMA connectors.
Voltage and Mating Details
Rated 250 V. The connector is free-hanging (in-line) and mates with any standard SMA jack (female) with a threaded interface. Single-port design. The silver housing colour is the natural stainless steel finish — no additional plating on the body.
