That assumes the parts are produced by exactly the same process, which 
is very often not a safe assumption.  One of them may undergo extra 
process steps, for example, or one or more process steps may be 
modified.  That's not at all uncommon, BTW -- "A" versions are often the 
product of process tweaks, not selected "non-A" devices.

Best regards,
