F-Type Bulkhead Jack for 75 Ohm Video and CATV
The 5-1634540-1: The female socket accepts standard F-type male plugs with a threaded coupling nut, and the nickel-plated zinc alloy body provides RF shielding and corrosion resistance. This connector is built for 75 Ohm systems — cable TV, CCTV, baseband video, and satellite IF distribution — where the impedance match to RG-6 or RG-59 cable is critical to return loss.
75 Ohm Impedance — Not a 50 Ohm Drop-In
Using this jack in a 50 Ohm system (common for test equipment or radio) creates a VSWR mismatch at the interface — the centre conductor diameter and dielectric geometry are optimised for 75 Ohm line impedance. The 1 GHz frequency ceiling covers analog CATV channels and standard-definition SDI, but not the full DOCSIS 3.1 spectrum or 4K video beyond that band.
Obsolete — Sourced for Legacy Racks
No official successor part number is recorded in the lifecycle data. For a legacy headend, distribution amplifier, or CCTV matrix that uses this exact bulkhead footprint, the only sourcing channel is the surplus and broker market. There is no pin-compatible drop-in replacement from the Greenpar ZDC series on record; a retrofit would require verifying the panel cutout diameter and the right-angle solder tail pattern against a current F-type jack.
Mounts through a panel hole with a front-side bulkhead nut, securing the connector to the chassis before the right-angle solder tails are soldered into the PCB. The shield termination is solder — the outer braid of the coax is soldered to the body, not crimped or clamped.
