This gives a mechanically rigid joint that handles the torque of bayonet mating without stressing the board traces. The dielectric is PBT/polyester, which handles the 500 V rating without breakdown at the 50 Ohm impedance. The 031-5329-51RFX is electrically identical — same 50 Ohm, 4 GHz, 500 V rating, same brass body and nickel finish — but swaps the center contact plating from gold to silver. For a clean lab bench at 25 °C, silver works. For a coastal site, a plating line, or any environment where the connector sees humidity or airborne corrosives, the gold on the 031-5329-52RFX is the safer call. The price delta between the two is small; the corrosion margin is not.","metaTitle":"031-5329-52RFX BNC Jack, 50 Ohm, 4 GHz, Through Hole","metaDescription":"031-5329-52RFX BNC jack, female socket, 50 Ohm impedance, 4 GHz max frequency, through-hole solder termination, gold center contact, 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":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Through Hole","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":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-53","Contact Termination":"Solder","Dielectric Material":"Polybutylene Terephthalate (PBT), Polyester","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9000","stockQuantity":16,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 031-5329-52RFX and get a price?","answer":"Current pricing and lead time are confirmed at quote time — submit a request with your target quantity and the distributor will respond with a firm price and availability."},{"question":"What is the closest functional second-source to 031-5329-52RFX?","answer":"The 031-5329-51RFX is electrically identical — same 50 Ohm, 4 GHz, 500 V rating — but uses a silver center contact instead of gold.
