The TE Connectivity 5-1634552-1 is an F-type jack, female socket from the ZDC/Greenpar series — a 75-Ohm RF connector designed for CATV, satellite IF, and broadband video distribution. It carries a 1 GHz frequency ceiling and a 500 V voltage rating, putting it in the broadcast-grade tier of F-connectors rather than the consumer-grade fittings common on set-top boxes.
This jack mounts through a bulkhead panel using a front-side nut — the threaded body passes through the panel hole and the nut tightens from the front, which means the connector can be installed or replaced without accessing the rear of the panel. The threaded fastening type gives a secure mechanical mate that won't vibrate loose in a head-end rack or outdoor pedestal.
The 5-1634552-1 is listed as Obsolete per the manufacturer. No official successor order code is recorded.
The 75 Ohm impedance is non-negotiable for this connector — it matches the characteristic impedance of CATV coax (RG-6, RG-11) and broadcast video distribution. A 50 Ohm system will see a mismatch reflection at this interface. The 1 GHz bandwidth covers the full DOCSIS 3.1 upstream and downstream spectrum plus satellite L-band IF, but not 5G mid-band or microwave links.
