Default Tantalum Capacitors

So I'm working on repairing a Korg MS2000B synthesizer for a friend with
a dead power supply. Here's the service manual:

The first thing I notice when looking inside is that the small SMT 100uF
10V tantalum capacitor C109 has completely vacated - it appears to be
gone, blown right off the board. There are some little fragments
rattling around in the case.

I have little experience with tantalum capacitors. Any suggestions for
a more reliable replacement?

One other option is Niobium Oxide caps, sold under the brand oxi-caps.
Digi-Key has them. I have used several thousand of them on some gear that
some users run in hard vacuum, so aluminum electrolytics were out of the
question. I have mis-connected a few of the oxi-caps, and can verify they
will char a bit, but not burst into flame.
