I am unable to find this part, but given enough effort, you might be able to adapt something to work.
Rock Auto has several yaw rate sensors available, but nothing tied to 2003 Explorer compatibility. You might take a good look at yours and note the shape and connector pin arrangement to try to find a nearest match and/or use further investigation of adapting different sensors to work.

Here are some alternative motorcraft part #'s to search for:
3L2Z-3C296-AA (4WD version?)
3L2Z-3C296-BA (2WD version? IDK what difference it would make)
2C5Z-3C187-AB
3C187 or 3C296 - anything with these strings in the part # - I do NOT suggest that any of these would work, just that it's the remaining piece of info on trying to find new old stock motorcraft parts that "might" be electrically compatible even if the connector needs changed.
I'd also check your connectors and wiring, as I have read that this part is not one that often fails... but that could be before it gets to be ~22 years old, everything has a lifespan.
