/diy/ - Do It Yourself

first, figure out what the caps are doing by tracing out that part of the circuit. it looks like it's involved with Q2 on the other side. you would then read the marking and search for that SMD marking using your favorite search engine or an SMD codebook like s-manuals.com/smd to see what it does, if there are reference/example circuits in the datasheet. at a guess, it looks like a pretty usual voltage regulator with enable. I can't read the marking on the board photos I was able to find, but if this cap is a decoupling cap, larger is better
so now verify the size (you could get out your calipers and measure, or eyeball with a scale if you have a mm scale). to me, based on the tact switch being a 6mm model, I'd say those caps are only 1mm long, therefore probably 0402 (inch). I saw an image that had a pictorial view of the two caps (promise) and showed C8 was somewhat taller than C7, looked to be almost square from the terminal end. 1µF is the biggest commonly available 0402 cap, and will almost certainly do, unless you can track down the code and find that the datasheet forbids that large a cap (unlikely). looks like that's not in a particulary fun place on the board. tacky flux is your friend. happy tweezing
