Mounting is a hybrid: panel mount through a bulkhead with a front-side nut, plus a right-angle through-hole solder tail for the PCB. The zinc die-cast body with nickel finish provides the RF shield continuity, and the polypropylene dielectric keeps the 75 Ohm line consistent through the launch. ## 50 Ohm vs 75 Ohm — the Cross-Shop Decision The 031-71052 is a 75 Ohm BNC. The only functional difference is the impedance — 75 Ohm vs 50 Ohm — and the 031-5538-10RFX adds a board lock feature and ships with the lockwasher and nut included. If your system impedance is 50 Ohm, the 031-5538-10RFX is the correct pick; if it is 75 Ohm, this is the one. The 31-5431 and 31-5640-1010 are also 50 Ohm BNC jacks with the same 1 GHz rating and 500-cycle life, differing only in features (isolated vs board lock) and housing color. None of the three peers carry a 75 Ohm impedance — that is the distinguishing mark of the 031-71052.","metaTitle":"Amphenol RF 031-71052 BNC Jack, 75 Ohm, 1 GHz, 500 Cycles","metaDescription":"Amphenol RF 031-71052 BNC jack, female socket, 75 Ohm impedance, 1 GHz max frequency, 500 mating cycles, gold center 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":"Board Guide","Includes":"-","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Silver, White","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"1 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-71","Contact Termination":"Solder","Dielectric Material":"Polypropylene (PP)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f077db7f1f9392c68575ec9a5b26496c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-71052/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of the 031-71052?","answer":"It is rated to 1 GHz with 0.2 dB insertion loss, matching the impedance of video and telecom cable."},{"question":"Is the 031-71052 RoHS compliant?","answer":"The 031-71052 carries a nickel body finish and gold center contact plating — materials consistent with RoHS compliance, though the official compliance statement should be verified against the manufacturer's documentation for your specific shipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-71052","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/031-71052 when reusing this data.
