The dielectric is polymethylpentene (PMP), a low-loss thermoplastic that holds the impedance through the interface. The 4 GHz upper frequency covers L-band through S-band and most of C-band; above that the BNC interface geometry starts to mode, so this connector is not the right choice for Ku-band or higher. For a test-bench application that sees daily connects, 500 cycles is a few years of service; for a fixed installation it is effectively a lifetime rating. ## Mounting Hardware and Installation This connector ships as three pieces: the connector body, a lockwasher, and a hex nut. The mounting feature is bulkhead — front side nut — meaning the connector body slides through the panel from the outside and the nut tightens from behind. The lockwasher sits between the nut and the panel to prevent the connector from rotating under cable strain. The isolated feature means the shell is not tied to the center conductor ground path — the shield termination is through the solder tails, not the panel. ## Obsolete — Sourcing the 227161-3 Today No official replacement order code is listed on record. If you are designing a new board, look at the current TE BNC jack family with the same 50 Ohm impedance and panel-mount bulkhead footprint; the pitch and PCB hole pattern may differ, so verify the layout against the new part drawing before committing.","metaTitle":"TE 227161-3 BNC Jack, 50 Ohm, 4 GHz, Panel Mount Right Angle","metaDescription":"TE Connectivity 227161-3 BNC jack, 50 Ohm impedance, 4 GHz max frequency, panel mount bulkhead with right-angle solder tails, gold-plated center contact, 500","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":"Board Guide, Isolated","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc","Housing Color":"Silver, White","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Obsolete","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"227161","Contact Termination":"Solder","Dielectric Material":"Polymethylpentene (PMP)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/72f9aab225d0d4aa0b9c08f9ba092323.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 227161-3?","answer":"The 227161-3 is obsolete and not stocked on the shelf.
