The connector is specified for Belden 8281, 8281F, and 9231 cable groups — these are precision 75 Ohm coax cables with a solid or foam polyethylene dielectric. The crimp termination on both the center contact and the shield (shield termination is also crimp) produces a gas-tight, repeatable assembly when paired with the correct crimp tool and die set. Electrical performance is clean: 0.15 dB insertion loss up to 2 GHz, with a voltage rating of 500 V. The zinc body with nickel finish provides RF shielding and corrosion resistance in studio or field environments. The 500 mating cycles are driven by the gold-plated center contact. Gold over brass resists corrosion and maintains low contact resistance through repeated connect/disconnect cycles in field-serviceable installations. For a permanent install that mates once, the cycle life is irrelevant — but for test points or portable camera cables, 500 cycles is a solid service life before replacement. Cable compatibility is limited to the listed Belden types (8281, 8281F, 9231) because the crimp dimensions and dielectric diameter are matched to those specific cables. Using a different 75 Ohm coax with a different jacket OD or dielectric diameter will not produce a reliable crimp or maintain the 75 Ohm impedance through the termination.","metaTitle":"TE Connectivity 221185-5 BNC Plug, 75 Ohm, 2 GHz, Obsolete","metaDescription":"TE Connectivity 221185-5 BNC plug, 75 Ohm impedance, 2 GHz max, 0.15 dB insertion loss, 500 mating cycles.

It is sourced through independent distribution against an RFQ — current availability and pricing are confirmed at quote time. Submit your BOM quantity for a same-day sourcing check."},{"question":"What is the replacement for 221185-5?","answer":"There is no manufacturer-declared direct replacement for the 221185-5. For a 75 Ohm BNC plug with similar specs, review current TE BNC offerings in the 75 Ohm impedance class — confirm the cable group compatibility and crimp tooling before substituting."},{"question":"What cable group is compatible with 221185-5?","answer":"The 221185-5 is specified for Belden 8281, 8281F, and 9231 cables. These are precision 75 Ohm coax cables; using a different cable may not produce a reliable crimp or maintain the 75 Ohm impedance through the termination."},{"question":"What is the insertion loss of 221185-5?","answer":"The insertion loss is 0.15 dB, measured up to the 2 GHz maximum frequency. This is a low-loss figure for a BNC plug — suitable for video distribution where signal integrity matters over multiple mated pairs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/221185-5","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/te-connectivity-amp-connectors/221185-5 when reusing this data.
