I’m working on a part that needs a replacement sensor. The number on the sensor is A42E and I can’t find a replacement. It has 3 leads on one side and the opposite appears to have a ground plane that is connected internaly to the center lead. I believe its a SOT23 device? Any help would be greatly appreciated.

Hi galada52,
If possible, could you please send an image of the device? Your description sounds more like a SOT-223 (a.k.a. TO-261) package.
