Why use a tantalum instead of a ceramic capacitor?
113 1 8. General note: ESL and ESR aren't the only "nonidealness" measures for a capacitor. One that's often overlooked is nonlinearity, usually quantified via THD. In that regard, both tantalum and ceramic are among the worse types, with some ceramics being really really bad. – leftaroundabout.

Replacing a tantalum capacitor on a Tandon tm-100-2A drive
Running an electrolytic significantly below its rated voltage can cause spotty erosion of the dielectric. This can lead to earlier failure. Still, the capacitor will likely last longer than the tantalum cap you took out. I wouldn't worry about it. As for value, anything from 0 to 15uf would most likely work fine.

Capacitor Questions
I therefore suggest replacing tantalum capacitors with the film variety. As previously stated, if the ESR was crucial to damp a circuit, then a 1 to 3 Ω resistor could be placed in series with the film capacitor to match the ESR of the original tantalum. But, aside from the LDO regulators, that issue is not likely to arise.

Capacitor Questions
Tantalum capacitors increases distortion because the capacitance alters with (a) applied DC bias voltage, (b) applied AC voltage, and (c) frequency; the effects are consequently non-linear (higher on one side than the other) and thus harmonic distortion. The THD of a tantalum capacitor exceeds that of ceramics, which are awful.

The lower ESR allows a ceramic capacitor with a lower capacitance value to easily replace a tantalum capacitor without any loss of functionality, according to Murata. Average lead times for the standard GRM Series of ceramic capacitors, which offers a capacitance range from 0.5 picofarad up to 47 microfarads, is about 10 to 12 weeks.
