Body is zinc die cast with nickel finish; dielectric is polypropylene, which holds the 50 Ohm impedance stable across the band. ## Sizing the Mount and the Signal Path Rated 500 V and 500 mating cycles — the voltage limit is the air gap at the interface, not the dielectric; the cycle count is driven by the gold-on-phosphor-bronze contact pair, which handles regular reconnects in test or field-service gear without the contact resistance drifting. The board guide and isolated features help align the connector during panel installation and keep the shell from shorting to adjacent circuitry. The right-angle termination means the signal pin exits the PCB parallel to the board — plan the trace from the launch pad to maintain the 50 Ohm characteristic impedance through the transition. ## What Crosses When the Original Is Dry? The 031-5538-10RFX shares the same BNC jack form, 50 Ohm impedance, 1 GHz bandwidth, 0.2 dB insertion loss, and 500-cycle gold-plated phosphor bronze contact. The difference is the housing color (black and silver vs silver and white) and the addition of a board lock feature on the 031-5538-10RFX for extra PCB retention. If the 031-5486 is on allocation, the 031-5538-10RFX is a functional swap — same electrical performance, same panel-mount bulkhead fit, same solder termination. The 31-5431 is electrically identical but lacks the board lock and features variation; it's a straight parametric match for the 031-5486.","metaTitle":"Amphenol RF 031-5486 BNC Jack, 50 Ohm, 1 GHz, Right Angle","metaDescription":"Amphenol RF 031-5486 BNC jack, female socket, 50 Ohm impedance, 1 GHz max frequency, 0.2 dB insertion loss, 500 mating cycles.","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, Isolated","Includes":"-","Impedance":"50Ohm","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":"031-54","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":"$6.0600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-5486/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 031-5486?","answer":"50 Ohm nominal — the standard characteristic impedance for BNC connectors used in RF and video signal paths."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-5486","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/031-5486 when reusing this data.
