This weekend my IBM 5160 XT would not boot up. I thought it was an issue with the PSU but following steps in the 'Minimum Diagnostic Configuration' guide from Minuzerodegrees (here), turns out that the infamous Tantalum capacitor C58 had died quietly, no blow ups, smoke or no burn marks, ...still looked like new yet dead. After removing it the machined booted up again. This is a 3 legs (-+-) 10uF 16V ceramic capacitor, I am looking for a replacement here in Japan but I find mostly 10uF 50V 2 legs ones. I am aware that I can use the 2 leg capacitor but not sure that replacing it with a 50V rated one will actually work. As far as I know it is possible to change capacitors with others of higher voltage but the step from 16V to 50V... seems quite a jump. Anyone knows if using a 50V capacitor instead of 16V would work?
