The TE Connectivity 5413631-2 is a BNC jack, female socket, designed for through-hole right-angle PCB mounting. It carries a 50 Ohm characteristic impedance and is rated to 4 GHz maximum frequency — standard for test equipment, instrumentation, and telecom patch panels where a quick bayonet-lock connection is needed. The tin-plated zinc body provides adequate RF shielding for indoor use, and the PTFE dielectric keeps impedance stable across the band.
Mates with any standard BNC plug with bayonet lock. The female socket accepts a male center pin; the bayonet coupling provides positive retention without tools. Solder termination on both the center contact and shield — no crimp tooling required, but hand or wave soldering is needed for the through-hole tails.
This part is listed as Obsolete per the manufacturer. No official replacement or successor order code is on record. For existing BOM lines, the 5413631-2 is sourced through surplus and independent distribution channels — quoted to order against an RFQ. Confirm availability and any last-time-buy windows at quote time.
The gold-plated beryllium copper center contact is rated for 500 mating cycles — sufficient for test bench and patch panel duty where the connector is mated and unmated regularly, but not designed for daily field connect/disconnect in harsh environments. The -55°C to 85°C operating range covers indoor industrial and lab conditions.
