The gold-plated contacts resist fretting corrosion over repeated insertions, which matters for field-serviceable equipment where the cable is plugged and unplugged regularly. If your application requires a USB mini B that will see daily connection cycles, this connector is specced for it. ## Compatibility and Pinout This is a USB mini B plug — it mates with any standard USB mini B receptacle. The 5-pin pinout follows the USB 2.0 standard: pin 1 (VBUS, +5V), pin 2 (D-), pin 3 (D+), pin 4 (ID, not connected in mini B), pin 5 (GND). It is not compatible with mini A receptacles, which have a different mechanical keying. The connector is USB 2.0 compliant, meaning it supports 480 Mbps data rate and is backward compatible with USB 1.1 and 1.0 devices. ## Sourcing Reality for a Last-Buy Part The UX20-MB-5P carries a Last Buy lifecycle status. Hirose has announced end-of-production — the part is no longer being manufactured and is only available through distributor inventory that has not yet sold through, or via a last-time-buy window that has likely closed.","metaTitle":"Hirose UX20-MB-5P USB Mini B Plug, 5 Contacts, Last Buy","metaDescription":"Hirose UX20-MB-5P USB mini B plug, 5 contacts, USB 2.0, 1A, 5V, 5000 mating cycles, through-hole vertical mount.
