Hello, I would really like to use this module for recycling old power supplies to charge USB-C.

I tried to make a test batch of boards with JLCPCB but the inductor (JSHC0650H-220M-G) has been out of stock for many months (and is not even listed on LCSC any more). As an alternative, I selected a substitute (C497873) but the board heats up like crazy (80c+ in some parts) when charging a standard phone with about 6-7w. I'm guessing the DC resistance is not low enough, but I couldn't find anything in the same range as the original part.

Could you suggest an alternative inductor for this design that is available?

Thanks for sharing these projects, I've learned a lot studying the designs!
