Hi,

Thank you for your inquiry. I am unable to find any cross reference regarding that particular part marking.

Hi [gunstedtrobin](https://forum.digikey.com/u/gunstedtrobin),

To give us a better chance of identifying it, can you provide some good quality images of this part? Also, dimensions of the body of the part may be useful as well.

In what sort of device is it used?

Thanks alot. Seems to be right. Pinout is correct. Component not broken, it’s corrosion. It’s a controllercard to a industrialismen servo motor.
