Will an alternator from a 1.6 fit my 2.0 focus

There both a 2002 zetec ford focus 16v. It's just my one is a 2.0, iv tried looking this sort of thing up but there's no definitive answer

if they are both the same year,and both the same size engine with the 8th digit of the vin# being a 3 or 5,then they are the same.if the 8th digit of the vin# is a P it is different *Without Zetec engine.the P is a SOHC engine,the other 2 are DOCH engines.
