The kit ships as 4 pieces: the connector body, a gold-plated brass centre contact, a crimp ferrule for the braid, and a sleeve that insulates the cable jacket entry. That hybrid termination — crimp the shield, solder the pin — is standard for field-installed BNCs where the braid needs a gas-tight mechanical grip but the centre conductor gets a soldered joint for lowest insertion loss (0.2 dB). ## Why 75 Ohm matters — and where this sits against the 50 Ohm siblings The 31-315-RFX and 31-320-RFX are the 50 Ohm siblings in the same Amphenol RF BNC family — same bayonet lock, same 500 mating cycles, same 0.2 dB insertion loss, same nickel-plated brass body. The difference that drives the selection: impedance and cable group. The 031-71013-RFX is 75 Ohm and mates with RG-179-class cables (thin, 75 Ohm video coax). The 31-315-RFX is 50 Ohm and mates with RG-174/RG-316 (thinner, 50 Ohm data coax). The 31-320-RFX is also 50 Ohm but steps up to RG-58 (thicker, higher power handling). A 75 Ohm plug on a 50 Ohm cable creates a 1.5:1 VSWR mismatch — don't cross them. The 031-70016 is the 75 Ohm bulkhead jack (female) that mates with this plug for a panel-feedthrough video path. ## Field termination checklist — crimp the braid, solder the pin Termination sequence for this kit: (1) slide the sleeve and ferrule onto the cable in order, (2) strip the cable jacket and braid to the dimensions in the Amphenol RF installation drawing for RG-179, (3) solder the centre contact onto the centre conductor — the gold plating wets well with a 60/40 or lead-free solder, (4) push the contact into the dielectric until it seats, (5) slide the ferrule over the braid and crimp with the correct hex die for RG-179 ferrule diameter.","metaTitle":"Amphenol RF 031-71013-RFX BNC Plug, 75 Ohm, RG-179, 3 GHz","metaDescription":"Amphenol RF 031-71013-RFX BNC plug, 75 Ohm impedance, crimp/solder termination for RG-179 cable. 3 GHz max frequency, 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":"4 pcs - 1 Connector, 1 Contact, 1 Ferrule, 1 Sleeve","Impedance":"75Ohm","Body Finish":"Nickel","Cable Group":"RG-179, 179A, 179B, 187, 187A, Belden 9221, M17/94-RG179","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"3 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"031-71","Contact Termination":"Solder","Dielectric Material":"Polyoxymethylene (POM) Acetal","Operating Temperature":"-40°C~80°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-71013-RFX/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 031-71013-RFX?","answer":"The 031-71013-RFX is an active-production Amphenol RF part.
