I am trying to replace a fuse marked 500mA/250 VP is this a direct replacement?

These are 500 ma/250v, but you also need to know if the fuse you need is slow or fast blow, and its size. These are 6x30mm, but fuses come in a number of sizes.

Fuses are equipment savers

Used these in my hand wired marshall amp. No issues. Had a bad tube and took one out, saved the amp, so I am happy.

Work very well, but a couple mm short.

These perform well when installed in my Onkyo amplifier/receiver. After measuring the cap fuses that came out of the unit, I ordered these as a replacement. They seem to be short in length by about 4mm. This does not affect performance much, since the fuse cradles have contacts wide enough to make sturdy connections even at the shorter length. I haven't popped one (thankfully), so I can't speak to how well they fail. But for the general pass-through performance of the product, it delivers what I needed for my system, and does so without creating any distortion or circuit issues.
