The listed cable group — AT&T 735, 735A, and Belden 735A1 — is a specific 75 Ohm series. If your reel holds a different 75 Ohm variant, check the cable OD against the ferrule ID before committing; the crimp die and ferrule are sized to this cable group. ## Mating and Mechanical Life Bayonet lock coupling with 500 mating cycles — typical for a mini BNC that sees occasional disconnect in a patch panel or field deployment. The PTFE dielectric holds the center contact concentric through repeated mates, keeping the impedance step at the interface within spec.","metaTitle":"Amphenol RF 31-70251 Mini BNC Plug, 75 Ohm, 4 GHz, Crimp","metaDescription":"31-70251 Amphenol RF mini BNC plug, male pin, 75 Ohm impedance, 4 GHz max, 0.1 dB insertion loss, 500 mating cycles.","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":"3 pcs - 1 Connector, 1 Contact, 1 Ferrule","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"AT&T 735, 735A, Belden 735A1","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Bayonet Lock","Insertion Loss":"0.1dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC, Mini","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"31-702","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.7800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/31-70251/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/31-70251","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/31-70251 when reusing this data.
