Greenpar MCX jack — 50 Ohm, 6 GHz, snap-on mating
The snap-on fastening gives a quick, positive mate — the coupling is audible and tactile, which matters when you're making multiple connections in a tight enclosure. Rated for 500 mating cycles, so it handles repeated connect-disconnect in test or field-swap roles without wearing the interface. The dielectric is PTFE, which holds a stable dielectric constant across the -65°C to 165°C operating range and through the frequency band. Termination is surface-mount with solder for both the centre contact and the shield — the SMT footprint keeps the RF launch short and repeatable, critical for maintaining the 50 Ohm impedance through the transition to the PCB trace. Insertion loss is listed at 0.1 dB, which is typical for a well-matched MCX interface at these frequencies.
This part is officially obsolete — TE Connectivity no longer manufactures the 1-1337582-1. There is no documented replacement or cross-reference on record from the manufacturer. For a BOM that requires this exact MCX jack, the only channel is surplus or broker stock. No stock-holding claim; every order is quoted individually.
What mates with it
As an MCX jack, this connector mates with any standard MCX plug (male) that uses the snap-on coupling interface. The 50 Ohm impedance is standard across the MCX family, so signal-integrity matching is straightforward as long as the cable or board-side plug is also 50 Ohm. The single-port, female configuration is the most common board-mount side for an MCX pair.
