little too small for that (electrolytic) ;)
0402 is the package format. i guess all caps in that size are ceramic ones.
i used a cap from a dead gta01 board which had a job near a rtc crystal
in his earlier life.
since the only new job is eating the rf which doesn't belong there, it
seems uncritical which type it is as long as the value is somewhat in range.
