This plug is built for RG-174 and RG-316 cable — two common small-diameter 50 Ohm coax types. The crimp termination for both centre pin and braid means a consistent, repeatable termination with the correct hex die set. No official replacement order code is on record. For a BOM that needs this exact TE part number, the channel is surplus and broker stock; expect to confirm quantity and lead time per request.","metaTitle":"TE Connectivity 2-221128-1 BNC Plug, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 2-221128-1 BNC plug, male pin, 50 Ohm impedance, 4 GHz max frequency, crimp termination, RG-174/188/316 cable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-174, 188, 316","Body Material":"Zinc","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":"Obsolete","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"221128","Contact Termination":"Crimp","Dielectric Material":"Polyethylene (PE)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.0800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/efb02254a8883d794e84d44e2544bbf7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 2-221128-1?","answer":"The 2-221128-1 is obsolete and sourced through independent distribution.
