Connector identity and application
The TE Connectivity 5-1814816-1 is a UHF-series jack from the ZDC, Greenpar line — a panel-mount female socket with a threaded coupling nut, designed for RF interconnect up to 500 MHz. The flange-mount body in nickel-plated zinc gives it a rugged, grounded shell suited for equipment chassis or bulkhead installations where the connector sees repeated mate/unmate cycles. Rated for 500 mating cycles, it holds up in test equipment, antenna ports, or instrumentation panels that get reconnected regularly.
The 500 V voltage rating and 500 MHz frequency ceiling define this as a medium-power, sub-GHz RF connector — not for high-frequency microwave work, but perfectly adequate for two-way radio base stations, broadcast transmitters, or industrial RF heating equipment where the signal path stays below UHF band. The tin-plated brass center contact (solder cup termination) is the cost-optimized choice for moderate-cycle applications; gold plating would extend cycle life further, but the 500-cycle rating already covers field-service and bench-test duty. The threaded coupling provides vibration-resistant retention — important when the cable is routed through moving equipment or near engine compartments.
No official successor order code is on record. If you are maintaining legacy equipment, verify your stock of mating connectors before committing to a last-buy quantity.
This jack mates with any standard UHF-series plug (male) with threaded coupling. Termination is solder cup on the center contact, with the shield soldered to the flange or body ground.
