Mini UHF Jack for Field Repairs on RG-58C and 141A
The TE Connectivity Greenpar ZDC 5-1814819-1 is a mini UHF jack, female socket, designed for free-hanging (in-line) mounting with a threaded fastening system. The center contact is gold-plated brass, crimp-terminated, and the shield is also crimped, making this a straightforward field repair for RG-58C or 141A coax cable.
The 5-1814819-1 is specified for a maximum frequency of 2 GHz with a non-constant impedance — it's not a 50-ohm precision connector, so treat it as a general-purpose UHF interconnect rather than a controlled-impedance RF line. The voltage rating of 335 V suits low-to-medium power RF applications. It accepts RG-58C and 141A cable groups, though the connector itself does not guarantee a constant impedance.
Obsolete — Sourcing for Legacy Repairs
If you're maintaining an existing harness that uses this connector, the three-piece kit (connector, contact, ferrule) means you can still re-pin or replace a damaged jack on site as long as you can locate stock. No official cross-reference exists, so confirm the cable group (RG-58C or 141A) and the threaded interface match your setup before ordering.
