Analogue-sequencer

In looking for the fuse for the main PCB i followed the US BOM and 
found the part number to be no longer available, mouser suggested an 
alternative which was this 
http://www.mouser.com/search/ProductDetail.aspx?R=TR1%
2fMCRW500MAvirtualkey50400000virtualkey504-MCRW-500MA

I realise now that the part i should have got was this
http://www.mouser.com/search/ProductDetail.aspx?R=MF-R050-0-
99virtualkey65210000virtualkey652-MFR050-LF

The one i got is described as a Axial Lead Non-Time Delay Fuses 
125V .5A, Fast Acting Wire-in-Air 
Whereas the part spec'd is described as Radial Lead Resettable 
Fuses .5A 60V 

Fuses are i guess something i havent come across so far in DIY synth 
stuff so i'm not sure if this is a problem or not? i figured i 
should ask before i powere the P3 on for the first time.

Thanks to all that helped me to get this finished by answering my 
questions ;)
