The gold-plated contacts and 10,000 mating cycle rating tell you this is built for frequent plug/unplug duty, well beyond a typical consumer USB port.
What the 10,000 Mating Cycles and Splash Proof Rating Mean on Site
10,000 mating cycles is an order of magnitude above the 1,500–5,000 cycles you'd see on a standard micro USB connector. The splash proof rating (IPX4-class, though not explicitly IP-rated in the spec) means it can handle rain splash or a wet shop floor without failing, as long as the mating plug also carries a seal. On site, if you're re-terminating a cable, the receptacle itself is soldered to the board — not field-repairable without rework — so the high cycle life is your main reliability lever.
Both are 5-contact, shielded, splash-proof micro B receptacles with the same 1.8 A, 30 VAC rating and 10,000 cycle life. The key difference is mounting: the ZX62WRD-B-5PC uses a reverse-mount, right-angle SMT footprint, while the ZX62WD1-B-5PC is a bottom-mount, horizontal SMT part and adds a board lock feature for extra SMT solder-joint retention during reflow and vibration. If your board layout calls for the connector on the underside with a reverse cable exit, the ZX62WRD-B-5PC is the one; if you need a standard bottom-mount with a board lock for mechanical security, the ZX62WD1-B-5PC is the alternative.
