Jdm-050 missing capacitor value needed

Hi people. I need a capacitor value and size which got knocked off while reflowing the pmic d92003mw.

10uF, 0603

No idea on the voltage spec, just go on the hi side to be safe.
Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up.

Thanks. I replaced that but it functions on battery and Bluetooth perfectly (with an issue) and when I connect USB cable to pc, the pc makes USB plugged in and then unplugged sound repeatedly.

The issue that I mentioned is,  usually ds4 on plugging the battery, there is a startup cycle. It draws approx 40 to 50mA for about 2 seconds and then comes down to 0.1mA. This one  is taking 80mA and then rests at 30mA (that's a 30mA leakage and hard to detect even via thermal can). I'm suspecting the mt3610n chip maybe faulty. I did try reflowing.

My question is are the jdm-050 and -055 mt3610s interchangeable?

I'm sorry RDC, I didn't check thoroughly it seems. I found a shorted capacitor near this pmic. Do you have the value for this? It's the same size 0603

Nvm, I just replaced with 10uf (just a guess) and the controller now works perfectly. Thanks ✌
