Change Power IC PIXEL 3XL

"I have a Google Pixel 3XL phone that stopped working because of a faulty Power IC, and it needs to be replaced. The part on the phone has the following numbers: PM845 002 G36F821 FK821 10. When I searched to buy a replacement, I couldn’t find one with the same exact numbers. Are these numbers important, or is it only the "PM845 002" part that needs to match?"
