The connector is rated to 1 GHz with a 0.1 dB insertion loss, which keeps the signal clean through a multi-drop tap or wall plate. This receptacle is built for RG-179, RG-179B, RG-187, RG-187A, Belden 9221, and M17/94-RG179 cables. The center contact crimps onto the signal conductor, and the shield ferrule crimps over the braid. ## Threaded Fastening and Panel Fit Fastening is threaded — the mating F Type plug screws onto the receptacle body, giving a vibration-resistant connection that will hold through 500 mating cycles. The bulkhead mount uses a front-side nut, so the receptacle body stays fixed while the nut tightens from the panel exterior. Rated for -40°C to 140°C, so it can live in an outdoor CATV pedestal or a satellite LNB housing. The kit includes the connector, ferrule, lockwasher, and nut — four pieces total, shipped in bulk packaging.","metaTitle":"Amphenol RF 531-40078 F Type Receptacle, 75 Ohm, 1 GHz","metaDescription":"Amphenol RF 531-40078 F Type receptacle, female socket, 75 Ohm, 1 GHz max, 0.1 dB insertion loss, panel mount, crimp termination.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"4 pcs - 1 Connector, 1 Ferrule, 1 Lockwasher, 1 Nut","Impedance":"75Ohm","Body Finish":"Tin","Cable Group":"RG-179, 179A, 179B, 187, 187A, Belden 9221, M17/94-RG179","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"F Type","Frequency - Max":"1 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"531","Contact Termination":"Crimp","Dielectric Material":"Polypropylene (PP)","Operating Temperature":"-40°C~140°C","Center Contact Plating":"Tin","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/98e364ddfbc1527bc7e8150543ca07c7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/531-40078/alternatives.json"},"ai":{"faq":[{"question":"Is 531-40078 a 75 Ohm BNC connector?","answer":"No — the 531-40078 is an F Type receptacle, not a BNC. It uses the threaded F Type interface standard for CATV and satellite equipment, with a 75 Ohm impedance. A BNC connector uses a bayonet lock and a different interface geometry."},{"question":"What cable is compatible with 531-40078?","answer":"It is compatible with RG-179, RG-179A, RG-179B, RG-187, RG-187A, Belden 9221, and M17/94-RG179. It is not designed for RG-59 — the dielectric diameter and braid coverage of RG-59 will not fit the ferrule or center contact."},{"question":"What is the insertion loss of 531-40078?","answer":"The specified insertion loss is 0.1 dB, measured at 1 GHz. That is low for a threaded F Type connector and indicates a well-controlled impedance match through the interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/531-40078","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/531-40078 when reusing this data.
