I'm using the TIP120 because its emitter pin uses no more than 5 Volts which is what you're looking for with the Arduino - so you could find any part that has the same properties and it should be OK. You'll see its collector pin can handle around 60 Volts (I think). If you have any issues I have a few spare TIP120's :) TIP121 should be fine if you look at the datasheets they’re basically identical.

Would it be possible to use a Tip121 instead? Im living in Ireland and am finding it very difficult to get a Tip120. Would it be possible to use a Tip121 instead?
