The 5221199-5: It ships as a kit containing the connector body, one contact, one ferrule, and one sleeve — everything needed to terminate one cable end. The 75 Ohm impedance and 2 GHz maximum frequency target this at video, broadcast, and broadband data applications rather than 50 Ohm radio or test equipment.
Lifecycle Status — Obsolete, No Official Replacement Listed
For new designs, a parametric search on 75 Ohm BNC jacks for RG-179 with crimp termination will turn up current-production alternatives, but no direct drop-in replacement is documented.
The 5221199-5 terminates to RG-179 cable using a standard crimp process — the centre contact crimps to the conductor, the ferrule secures the braid and jacket. The free-hanging in-line mount means this connector is not designed for panel or PCB mounting; it lives on the cable end. The kit format (connector + contact + ferrule + sleeve) simplifies procurement for field replacement or small-batch harness builds — one order code covers the entire cable-end assembly.
