MCX Receptacle, 50 Ohm, 6 GHz — Now Obsolete
The 1060989-1: It carries a single female socket on a through-hole solder termination, with the shield soldered to the board ground plane.
Obsolete — Sourcing the 1060989-1
That means the factory line is shut — no new production runs. For a BOM that still calls out 1060989-1, the options are surplus inventory or an approved replacement. There is no official TE replacement listed in the lifecycle record, so a pin-compatible substitute requires checking the MCX catalog for a current-production equivalent with the same footprint and 50 Ohm impedance.
The 6 GHz ceiling covers most common wireless bands (Wi-Fi, cellular, ISM) but falls short of higher mmWave applications. The 335 V rating is unusually high for an MCX; it means the dielectric spacing and creepage path support RF power levels that would arc across a typical signal-only connector. The snap-on fastening is quick to mate but provides less axial retention than a threaded SMA — fine for panel-mount or board-edge use where the cable isn't under constant tension.
