Question:

Can I use a 1.5 fuse instead of 1.6 on a circuit board?

I am having a hell of a time trying to find a 1.6 micro mini fuse for a circuit board with wire leads on them. I need ones that are fast acting (so far, I have only been able to locate slow)Is it possible that I can replace the 1.6 fast acting with a 1.5 fast acting? I have a 1.6 slow fuse with leads on them. But I heard that you shouldn't use a slow fuse with sensitive electrical components where there had been a fast acting fuse prior. (I would only be running at most 50w)Thanks for any help you may offer, I am much obliged

Answer:

I assume that you've already blown the 1.6 amp fuse. Have you found the cause? Although putting a smaller rated fast fuse in it's place is normally OK for the short time it takes to find the correct size, electronics are very precise in amperage. I wouldn't use the 1.5 fast or the 1.6 slow in place of the 1.6 fast. You're taking a risk that is not necessary if this is an expensive piece of equipment. Wait and find the correct one.
I'm sure that your 1.6a fuse will not be running at 1.6a, so I guess that a 1.5a fast fuse (Flink) would be ok, 0.1 amp is not a huge difference. Dont know about the wire leads, could you not fit a fuseholder instead and use this? maplin .uk/Module.aspx?Modu maplin .uk/Module.aspx?Modu
