USB micro AB Receptacle for High-Cycle Portable Applications
The Hirose ZX62-AB-5PA(31) is a USB 2.0 micro AB receptacle with 5 contacts, designed for surface-mount right-angle attachment to the bottom edge of a PCB. It belongs to the ZX series of miniature USB connectors and carries a shielded steel/stainless shell that provides the ground return path and EMI containment for the differential data pair. The gray insulation color and bottom-mount horizontal orientation are fixed — this is not a reverse-mount variant, so the PCB cutout and keep-out zone must match the standard micro AB footprint. The gold-plated contacts are specified for 10,000 mating cycles — well above the typical USB connector endurance — making this a candidate for test fixtures, medical peripherals, or any application where the cable is repeatedly plugged and unplugged over the product life.
Board Layout and Mounting Considerations
This is a surface-mount, right-angle receptacle with a bottom-mount, horizontal orientation. The solder retention feature and pick-and-place compatible packaging (Tape & Reel, Cut Tape) mean it flows through a standard SMT line with no hand-soldering step.
Positioning Within the ZX Series
The ZX62-AB-5PA(31) is the micro AB receptacle in the ZX family. The closest functional sibling is the ZX62D-AB-5P8(30), which shares the same 5-contact micro AB interface, 10,000 mating cycles, and 30 VAC rating, but is packaged in a Digi-Reel option. The ZX62RD-AB-5P8(30) is a reverse-mount variant (plug inserts from the opposite side of the board) and carries a higher 1.8 A per contact rating — useful if your layout requires the cable to exit the opposite face and you need more current headroom. The ZX62-B-5PA(33) is a micro B receptacle (not micro AB), so it accepts only micro B plugs, not the AB plug that can also mate with micro A connectors. For a standard bottom-mount micro AB with the 1 A rating, the ZX62-AB-5PA(31) is the direct selection.
