What sets this connector apart from a standard USB micro B is the 10,000 mating cycle rating — an order of magnitude above the typical 1,500–5,000 cycles for a consumer-grade micro USB. That cycle life comes from the gold-plated contacts and the stainless steel shell, which together resist fretting corrosion and maintain contact force through repeated mate-unmate cycles. ## Last Buy — Sourcing Reality for ZX64-B-5S-UNIT(31) The ZX64-B-5S-UNIT(31) carries a Last Buy lifecycle status. This means Hirose has announced end-of-life for this order code, and the remaining factory stock is being drawn down. No official successor or cross-reference part number is on record from Hirose for this specific variant. If your design can accommodate a form-fit-function alternative, a review of the current Hirose USB micro B portfolio is warranted, but no pin-compatible direct replacement is documented here. Surface mount, right angle — the SMT solder tails sit on the bottom of the connector body, and the right-angle orientation means the USB receptacle opening faces sideways off the board edge. The stainless steel shell provides EMI shielding and mechanical robustness; the solder tabs on the shell should be tied to the PCB ground plane for best signal integrity. The connector ships in tray packaging, which is typical for manual or low-volume pick-and-place — for high-volume reels, check the tray count against your feeder setup.","metaTitle":"Hirose ZX64-B-5S-UNIT(31) USB micro B Plug, 10,000 Cycles","metaDescription":"Hirose ZX64-B-5S-UNIT(31) USB micro B plug, 5 contacts, 1.8A, 30VAC, USB 2.0.
