F Type Plug for 75 Ohm RF Lines
The TE Connectivity 5-1814822-7 is an F type plug, male pin connector from the ZDC Greenpar series. It carries a 75 Ohm impedance and is rated to 1 GHz maximum frequency — the impedance and bandwidth together define the usable signal path for video distribution, CATV headends, and baseband RF links where 75 Ohm is the standard line impedance. The threaded fastening gives a vibration-resistant mate once torqued; the nickel-plated brass body handles the shield ground path through the twist-on shield termination.
This plug is specified for CT125 cable group — the cable diameter and dielectric match the crimp or clamp ferrule in the connector body. The shield termination is twist-on, which means the braid is folded back over the cable jacket and the connector body screws over it, making electrical contact without a separate ferrule. Free-hanging (in-line) mounting, no panel cutout needed.
Obsolete — Sourcing Path
No official replacement order code is on record for this exact F type plug variant. Confirm the cable group (CT125) and the 75 Ohm impedance match before committing to a substitute; an F type connector with a different impedance or cable group will not terminate correctly.
Operating Range and Environment
The wide temperature span covers outdoor enclosure and unconditioned headend installations — the connector lives inside a cabinet or on a drop cable, not exposed to weather directly. Single-port configuration.
