The 5413986-1: The nickel-plated zinc body and silver-plated beryllium copper center contact handle the 500 V rating across the 2 GHz bandwidth.
Key specs that decide the fit
The 500 mating cycle rating suits patch-panel and test-equipment duty where reconnections happen daily. Frequency response extends to 2 GHz, which covers SDI video, baseband RF, and instrumentation links through L-band. The through-hole solder shield termination gives a solid ground connection to the PCB plane, critical for maintaining the 75 Ohm reference through the transition.
