MLCC caps vs film caps

[Synchrony Pedalworks]

I have looked on the internet, but I am not finding a clear answer.

For our pedal building purposes, can a MLCC cap substitute for a film cap?

Thanks!

I'm pasting this from another post I made here. I did some research on this for a product I was making.

The only major issue I think you could run into is with the larger Class II MLCC, DC voltage can cause the capacitance to drop a significant amount. I was considering using them due to their size in a power supply, but ended up going with aluminum electrolytics instead for that specific circuit. I've attached a graph from a datasheet from Samsung that illustrates this effect. I believe using well overrated capacitors can somewhat offset this though.
