The 75 Ohm impedance and 4 GHz frequency ceiling match the standard 75 Ohm BNC interface. The PTFE dielectric keeps insertion loss to 0.2 dB across the band, and the gold-plated brass centre contact handles the 500-cycle mating life. ## Cable compatibility — RG-179 family and Belden 9221 This plug is specced for RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 — all 75 Ohm, 0.100-inch-diameter class cables with a solid or stranded centre conductor around 0.025-inch. The crimp ferrule and centre contact are sized for that cable OD; using a different cable gauge means the ferrule won't compress evenly and the impedance step at the termination will exceed the 0.2 dB insertion loss budget. ## 500-cycle mating life — gold on the centre contact The 500-cycle rating comes from the gold-plated brass centre contact mated against a phosphor bronze receptacle. Gold on the pin, nickel on the body — the body finish doesn't participate in the signal path, so the 500 cycles are real reconnect duty for field-service or test-rack use. The bayonet lock gives a positive mate without over-torquing, which is what wears out the plating on a threaded connector.","metaTitle":"Amphenol 031-80107 BNC Plug, 75 Ohm, 4 GHz, RG-179","metaDescription":"Amphenol 031-80107 75 Ohm BNC plug, male pin, crimp termination for RG-179 cable family. 4 GHz max, 500 mating cycles, gold-plated centre contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"5 pcs - 1 Connector, 1 Contact, 1 Ferrule, 1 Insulator, 1 Sleeve","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"RG-179, 179A, 179B, 187, 187A, Belden 9221, M17/94-RG179","Body Material":"Phosphor Bronze","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"031-80","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6aa370e29774a6635905db9741c758be.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-80107/alternatives.json"},"ai":{"faq":[{"question":"Is 031-80107 a BNC or TNC connector?","answer":"It is a BNC connector with a bayonet lock.
