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.
