Ultra-Miniature Coax Receptacle for 6 GHz Signal Paths
The Hirose W.FL2-R-SMT-1(10) is a surface-mount ultra-miniature coax receptacle from the W.FL2 series, designed for applications where board space is tight and signal integrity up to 6 GHz matters. It presents a 50 Ohm impedance through the interface — match that to the PCB trace impedance or you'll see a reflection at the launch. The snap-on fastening gives a positive tactile lock in a package small enough for handheld and IoT radio modules. Rated DC to 6 GHz, this single-port receptacle uses a male pin center contact with gold plating over brass, housed in a Liquid Crystal Polymer (LCP) dielectric. The body is phosphor bronze with a silver finish, and the shield terminates to the board through solder pads — standard SMT reflow assembly. The 20 mating cycle rating tells you this is a low-cycle connector, typical for a one-time board-to-cable mate in production or a field-replaceable module that stays mated for its service life.
Last Buy — Sourcing Decision
The W.FL2-R-SMT-1(10) carries a Last Buy status from Hirose. That means the factory has announced end-of-life — remaining stock is the final production run. For a BOM that requires this connector, the path is to source from surplus or broker inventory. If your design is still in development, consider evaluating the current W.FL2 series portfolio for a replacement that matches your frequency and footprint requirements.
This is the receptacle (board-mount) half of the W.FL2 interface. It mates with the corresponding W.FL2 series plug on the cable assembly. The snap-on retention means the cable-side plug pushes on and locks with an audible click — no threaded coupling.
