The standout spec here is the 10000 mating cycle rating — an order of magnitude above the typical micro USB connector, which usually rates around 5000 to 10000 cycles for the reinforced versions. This makes the 1981568-1 a candidate for field-serviceable equipment or test jigs where the cable is plugged and unplugged regularly.
Current rating and signal assignment
The current rating is listed as 0.5A, 1A, and 1.8A — these correspond to the standard USB 2.0 pin assignment: the VBUS power pin carries up to 1.8A, the ground pin up to 1A, and the D+/D- signal pins are limited to 0.5A. The 30V voltage rating covers the VBUS line comfortably, with headroom above the 5V USB standard.
