A hybridized connector apparatus is provided for solder connection with a central conductor of an associated coaxial cable and for crimp connection with a conductive braid and foil of the coaxial cable, and includes a hollow, generally cylindrical contact pin member or tip portion operably received into an interior of a generally ring-shaped dielectric spacer disk. The dielectric is received into a connector body, which is received into a shell. An end of the contact pin member defines an interface portion having a substantially constant outer diameter D extending outwardly from the spacer disk beyond an extent of the body member in an insertion direction I. The interface portion defines a semicircular edge portion and may also include a linear edge portion disposed in a plane substantially oblique to the longitudinal axis, and a curvilinear edge portion.
