USB micro B receptacle with 10000-cycle endurance
The 629105136821 is the 5-contact USB micro B receptacle in Würth Elektronik's WR-COM series, rated for USB 2.0 signal rates.
Mating cycles and board retention
Rated for 10000 mating cycles — the gold contact finish supports repeated connect-disconnect duty without fretting corrosion. Board guide and solder retention features hold the connector in place during reflow; the right-angle SMT termination keeps the receptacle parallel to the PCB edge.
Position count across the WR-COM micro USB family
Within the WR-COM micro USB series the 629105136821 (micro B, 5 contacts) sits alongside the 629105150521 (micro B, 5 contacts) and the 629105150921 (micro AB, 5 contacts) — the pitch, shell size, and footprint are shared across the family, so the selection decision is between micro B and micro AB receptacle type.
