The TE Connectivity 5-1634503-1 is a BNC jack, female socket, part of the Greenpar ZDC series. It is a 50 Ohm RF connector rated to 4 GHz, with a bayonet lock coupling for quick connect/disconnect in test and instrumentation setups. The through-hole solder termination suits PCB mounting, and the zinc alloy body with nickel finish provides RF shielding and corrosion resistance.
This part is listed as Obsolete per the manufacturer. No official successor or cross-reference is on record. For existing BOM lines, the connector is sourced through independent distribution — quoted to order against an RFQ.
The centre contact is gold-plated phosphor bronze, rated for 500 mating cycles — sufficient for repeated field service or test jig use. The dielectric is polymethylpentene (PMP), and the operating temperature range spans -55°C to 85°C.
