I can't find any 10 amp SFE fuses anywhere!  The SFE is for automotive and only holds up to 32V.  The AGCs are all purpose and go to 250V.  I have the 20 amp SFE and was wondering if it would be okay to use the 10 amp all purpose fuses?

Thanks for any help.

The voltage rating for the fuse must be at least equal or grater than the maximum voltage of the circuit it's protecting.  The current rating is of course the most important factor.  The 250v fuse rating will be fine for our cars.

Is the original recommended fuse really from the SFE series? The reason I ask is that the thing that makes the SFE series interesting is that the fuse lengths increase as the amperage rating goes up. I haven't researched it, but my assumption is that it's a safety thing with the intent that you can't fit a higher amp fuse into a spot where a lower one belongs because the body will be too long.

So what's the point? The point is that I thought all the Z fuses were the same length, and if they're using the SFE series, then they will all be different lengths.

At 20A, the SFE series and the AGC series are the same length meaning that an SFE20 and an AGC20 are the same length. And the AGC series doesn't do the same thing with the lengths that the SFE series does. An AGC20 is the same length as an AGC10.

 

Here's some info from Littelfuse:

All the 20 amps were replaced and are the right length, comparing them to the old ones.  I'm glad I changed them out too, there was a 30 in the mix.  I haven't changed the 10s yet but after reading what you've posted about the AGCs I'm sure they will be okay.  

Thank you. 

Yeah, the AGC series will be perfect.

So if I take a guess as to why you were looking for SFE10's in the first place, I would surmise that you pulled the old fuses out of the fuse block and found a lot of SFE20's in there. Thinking that the SFE series was the correct fuse series, you then went looking for SFE10's to replace some of the lower value positions?

If that's the case, then you got caught by that simple trick that at the 20A rating, the SFE and the AGC series are the same length.

Where's my dead horse.... 

No dead horses ever to me.  I'll kick something until I starve to death, maybe a Southern thing, hard headed. 

As for your guessing abilities,

Makes perfect sense. Now go replace the rest of your droopy filaments.
