Probably not. They probably mount differently and could have different connectors.

You could go to your favorite auto parts store and have them look up the replacement part numbers for both vehicles.

Do you have the alternator in question? If it is physically the same, you probably can make the substitution.

You can look this up online yourself.  
I just did a quick check one one of the many online auto parts sites, and the alternator part numbers for a 96 Chevy S10 4cyl and 6cyl do indeed differ. That difference could be amperage related, mounting or pulley size related, or all of the above.

Or you could call a boneyard. They have cross reference data.
