Micro USB AB Receptacle — 5 Contacts, Shielded, 10,000-Cycle Duty
The Molex 475891001 is a micro USB AB receptacle from the 47589 series, designed for applications that need to accept either micro USB A or B plugs — the AB configuration handles both host and device connections in a single port. It carries 5 contacts in a single port, rated 1A and 1.8A at 30VAC, with gold-plated contacts that support the 10,000 mating cycle rating. The shell is shielded with steel and stainless steel, giving the EMI containment needed for USB 2.0 signal integrity in compact enclosures.
Mounting and Assembly Fit
This receptacle mounts surface-mount right-angle, with the connector body sitting horizontal to the PCB edge — the typical orientation for a board-edge USB port. The mounting feature is listed as horizontal, confirming the USB opening faces the board edge. The termination is solder only — no press-fit option here.
Shielding and USB Compatibility
The shielded construction (steel and stainless steel) means this connector is built for USB 2.0 data rates — the micro AB form factor is electrically compatible with USB 2.0 signaling. It is not rated for USB 3.0 SuperSpeed, which requires additional differential pairs the 5-contact micro AB footprint does not carry. The key difference between micro USB AB and micro USB B is that the AB receptacle accepts both A and B plugs, while a B receptacle only accepts a B plug. This makes the AB variant the right choice for On-The-Go (OTG) designs where the device needs to switch between host and peripheral roles.
