The 2-5329458-1: It handles signals up to 2.5 GHz and is rated for 500 V, making it a standard choice for RF test equipment, instrumentation, and low-power transmission lines where a quick-connect bayonet interface is preferred over threaded types.
The 50 Ohm impedance and 2.5 GHz frequency ceiling define the signal path. The cable group list — RG-161, 179, 179A, 179B, 187, 187A, Belden 9221 — tells you which coax diameters and dielectrics the ferrule and contact are sized for.
