Generally speaking, if it is for replacement, you should never use a fuse with a rating higher than the original as this would potentially create safety issues (e.g. fire, excessive downstream damage in…

That looks to me to be a Fast-blow type (hence F 8A, rather than T 8A). I didn't see any on element14 to be of the right value - the only 8A units seem to be time delay / slow-blow types which would…

Since you don't say where you are it's a little hard to help. Mouser have them: MK

Can you use a 10A fuse:

Generally speaking, if it is for replacement, you should never use a fuse with a rating higher than the original as this would potentially create safety issues (e.g. fire, excessive downstream damage in case of fault).

Using a lower value may be permissible but is likely to lead to nuisance fuse blowing.

You should also match the fuse time characteristics - some are quick/fast-blow and others are slow-blow/time-delay types. Using a fast blow type may lead to nuisance blowing in case of in-rush. Using a slow-blow type may fail to protect sensitive circuits.

Always best to make sure you have the complete part number and decode it as to its characteristics ... then search for a replacement. It doesn't necessarily have to be the same brand, as long as the size, voltage, current, time-characteristics are the same and the breaking capacity is equal or greater, then it should perform as per the original and maintain safety.

I didn't see any on element14 to be of the right value - the only 8A units seem to be time delay / slow-blow types which would not have the same response speed.
