This plug is built for RG-402 (.141\" diameter semi-rigid) cable — the cable group is specified in the part definition, so the centre conductor and dielectric dimensions match the push-on contact and the crimp ferrule fits the shield braid or outer conductor. The shield termination is crimp; the centre contact is push-on, meaning no solder pot to fill. On a harness bench, you cut the cable to length, strip the dielectric, push the centre contact onto the centre conductor, and crimp the ferrule over the braid. The threaded coupling nut secures the mate. ## Obsolete — sourcing path No official successor order code is recorded in the lifecycle data. If the design can be revised, a parametric search on 50 Ohm SMA plugs with RG-402 compatibility and 18 GHz rating will identify current-production alternatives, but no direct pin-compatible replacement is named in the official record.","metaTitle":"TE Connectivity 1050740-1 SMA Plug, 50 Ohm, 18 GHz, RG-402","metaDescription":"1050740-1 SMA plug, male pin, 50 Ohm impedance, 18 GHz max frequency, crimp shield termination, mates with RG-402 .141 semi-rigid 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":"-","Impedance":"50 Ohms","Body Finish":"-","Cable Group":"RG-402 (.141\\\" Semi Rigid)","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":"500 V","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"1050740","Contact Termination":"Push On","Dielectric Material":"-","Operating Temperature":"-65°C ~ 105°C","Center Contact Plating":"-","Center Contact Material":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7ecf87fe00e722ea03fe7b2a35141c74.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What cable does the 1050740-1 fit?","answer":"The 1050740-1 is designed for RG-402 (.141\" semi-rigid) coaxial cable.
