Was wondering if anyone could give me some insight here.

I have a device that has a 110*C 5 amp Microtemp fuse opened in it. and can't seem to find a 5 amp equivalent in that temperature. But I do have a 109*C 15 amp on hand. Was wondering if I were to put a 5 amp pico fuse inline with this 109*C @15 amp. would that not have the same protection? I'd have the temperature and amperage covered, so should function the same. What do you think? It seems to me that it would, ,
but just wanted to get some other opinions

Thanks, Sydwinder.
