Rated to 12.4 GHz maximum frequency, this plug covers the L, S, and C bands plus most of the X band — sufficient for Wi-Fi, cellular backhaul, GPS, instrumentation, and test equipment. The 500-cycle mating life, backed by gold plating on the centre contact, means it holds up under repeated connect-disconnect in lab or field-service use. The 901-9876-RFX is specced for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables. These are all 50 Ohm coax types with a nominal 0.195-inch jacket diameter and a 0.037-inch solid or stranded centre conductor. ## How It Compares to Nearby Siblings The 901-9881-RFX is the closest functional peer — same SMA plug format, same 50 Ohm impedance, same nickel body, same 500-cycle rating. The key difference: the 901-9881-RFX targets RG-174, 188, 316, and LMR-100 cables (smaller 0.110-inch jacket) and is rated 375 V versus the 901-9876-RFX's 500 V. If your harness uses RG-58, the 901-9876-RFX is the correct cable-group match; the 901-9881-RFX is for thinner, lower-voltage coax. The 901-9867-RFX is also an SMA plug but with a gold body finish and solder shield termination — it mates with RG-405 semi-rigid cable and reaches 18 GHz. That part is for semi-rigid installations where you solder both the shield and centre pin; the 901-9876-RFX is the crimp-shield alternative for flexible RG-58 runs.","metaTitle":"Amphenol RF 901-9876-RFX SMA Plug, 50 Ohm, 12.4 GHz","metaDescription":"Amphenol RF 901-9876-RFX SMA plug, male pin, 50 Ohm, 12.4 GHz max, crimp shield/solder contact, RG-58 cable group, 500 mating cycles, gold 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":"3 pcs - 1 Connector, 1 Contact, 1 Ferrule","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"SMA","Frequency - Max":"12.4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"901-98","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f1ae7cb215b012abd2fbd633f3ece6c4.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/901-9876-RFX/alternatives.json"},"ai":{"faq":[{"question":"Is 901-9876-RFX a 50 ohm connector?","answer":"Yes, the 901-9876-RFX is a 50 Ohm SMA plug, confirmed by the impedance specification."},{"question":"Does 901-9876-RFX include the ferrule and contact?","answer":"Yes, it ships as a 3-piece kit: the connector body, the centre contact, and the crimp ferrule."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/901-9876-RFX","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/901-9876-RFX when reusing this data.
