The TE Connectivity 1060984-1 is a 50 Ohm MCX receptacle, a snap-on coaxial interconnect built for board-edge RF signal paths up to 6 GHz. It's a single-port female socket with a through-hole solder termination — the centre contact is beryllium copper with gold plating, and the brass body carries a gold finish.
The gold body finish and PTFE dielectric both hold up at the high end without outgassing or degradation.
The closest functional sibling in the TE MCX family is the 415420-1, which shares the same series, Bulk packaging, and Active lifecycle status. Both are 50 Ohm snap-on receptacles; the 1060984-1 is the one you want when the BOM calls for this specific base number and the gold body finish. No direct second-source cross-reference exists — the 1057230-1 is an OSP jack, a different connector interface that won't mate with an MCX plug.
