For a test-equipment patch panel or a broadcast rack where connectors get swapped during reconfiguration, the 500-cycle rating gives a solid working life before contact wear starts shifting the impedance. ## Through-Hole Solder Termination and Dielectric That means the installer needs a soldering iron and a clean board, but gets a gas-tight joint that holds its RF performance across temperature cycles. Shield termination is also solder, so the ground path is continuous around the interface — important for keeping the 75 Ohm line from radiating or picking up noise.","metaTitle":"Amphenol 919-423J-71P12G MCX Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol 919-423J-71P12G MCX jack, female socket, 75 Ohm impedance, 12 GHz max frequency, 500 mating cycles, gold body, through-hole solder termination.","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":"-","Impedance":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"MCX","Frequency - Max":"12 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"91942","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1380e8876f8e5dd8a5ad2592225007ff.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/919-423J-71P12G/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for the 919-423J-71P12G?","answer":"The 75 Ohm impedance should be matched on both halves of the connection for signal integrity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/919-423J-71P12G","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/919-423J-71P12G when reusing this data.
