The extended insulation feature and 500 V voltage rating suggest it is built for environments requiring additional dielectric isolation, such as high-voltage RF circuits or industrial monitoring systems.
The 50 Ohm impedance and 4 GHz frequency ceiling define this connector's RF performance: it will pass signals cleanly up to 4 GHz with a VSWR typical of standard BNC interfaces. The 500 mating cycles mean it can handle regular connect/disconnect in a test-bench or field-service role without premature wear. The 500 V rating, paired with the extended insulation, gives headroom for signal paths that carry DC bias or higher-than-typical RF voltages. The solder cup termination requires hand soldering of the center conductor and shield tag — expect a clean, stable joint but not a high-speed assembly process.
Sourcing and lifecycle: 227169-7 is obsolete
No official successor part number is provided in the available records. For buyers with a BOM line that calls out this exact order code, the sourcing path is through independent distribution channels that carry surplus or last-time-buy inventory. If you need a form-fit-function alternative, the closest match will be a standard BNC jack with similar electrical ratings (50 Ohm, 4 GHz, 500 V) from TE's current BNC portfolio, but no direct cross-reference is documented here.
The panel-mount bulkhead design uses a rear-side nut and includes a lockwasher — the kit ships with the connector, lockwasher, and nut (3 pieces total). The shield is terminated via a solder tag, and the center contact via a solder cup. The nickel body finish and silver housing color are standard for BNC connectors in indoor or sheltered environments.
