Depends where used. if used in resonant tanks like IF filter, I would certainly not use anything other than mica or NPO/C0G if possible.

Y5P while not a bad cap overall, has the temp range up to 85C while mica operates up to 150C.
Mica is typically 50-70ppm per degree C which makes it roughly 0.3% over temp range in a radio whereas a Y5P over the same range will change up to 10%.

But if used in an RF filter, like in a plate detector, sure - why not.
