CMPS10 spare parts

[feoras]

I was desoldering the header on the CMPS10 so I could hard wire it and accidentally desoldered and lost the SMD capcitor that was beside the header.

Can you tell me the value of this capacitor so I can find a replacement. My guess is 0.1uF.

I am assuming it is a decoupling capacitor for the pic. My CMPS10 appears to operate ok without it. Should I bother replacing it?

Thanks
