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.","metaTitle":"TE Connectivity 1051665-1 SMA Plug, 50 Ohm, 12.4 GHz, RG-174","metaDescription":"TE Connectivity 1051665-1 SMA plug, male pin, 50 Ohm, 12.4 GHz max, for RG-174 cable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"-","Includes":"8 pcs - 1 Connector, 1 Bushing, 1 Contact, 1 Heat Shrink, 1 Insulator, 1 Nut, 2 Sleeves","Impedance":"50 Ohms","Body Finish":"-","Cable Group":"RG-174","Body Material":"Stainless Steel","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Obsolete","Voltage Rating":"250 V","Connector Style":"SMA","Frequency - Max":"12.4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"1051","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c2922d08b955f76fbb2885112e8361c9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1051665-1?","answer":"The 1051665-1 is obsolete, but it can be sourced through independent distribution.
