The PTFE dielectric keeps the impedance stable across the band, and the threaded coupling with a flange mount means it torques down to a panel and stays — no wiggle, no intermittent opens. The 18 GHz max frequency covers S-band, C-band, and most of X-band; if your signal chain runs above that, you need a different interface (SMA typically starts to mode at 18 GHz). The 500 mating cycles are standard for SMA — the gold-on-beryllium-copper centre contact takes the wear, and the gold body finish resists the corrosion that shows up on outdoor panels or in humid labs. The 335 V rating is the breakdown limit across the dielectric; in practice, RF power levels keep signal voltages well below that, but it gives you headroom if the line carries DC bias. No official successor order code is on record from TE for this part. If your application can tolerate a parametric alternative, a standard SMA panel receptacle with the same 50 Ohm impedance, 18 GHz ceiling, and flange mount from the same or a compatible series would be the practical swap — confirm the panel cutout and centre contact termination match your assembly before committing.","metaTitle":"TE Connectivity 1052551-1 SMA Receptacle, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity 1052551-1 SMA receptacle, female socket, 50 Ohm, 18 GHz max frequency, 500 mating cycles, gold body, panel mount.","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":"Extended Insulation","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Obsolete","Voltage Rating":"335 V","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"1052","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~125°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0b8c7292e4ee4c58e03d84472dfd4121.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1052551-1 obsolete?","answer":"Yes, the 1052551-1 carries an Obsolete lifecycle status from TE Connectivity.
