Those aren't FRU numbers, they're Option numbers.  Basically, they're 
what you specify as an option when ordering a particular system - they 
don't really mean anything when you don't specify what system they're 
for.  IBM FRU numbers are formatted like this: 12G2345 - two digits, a 
letter, and then 4 more digits.

That being said, some things with different FRU numbers are 
interchangable, and any two thing that have the same FRU number are 
pretty much guaranteed to be interchangable (unless they differ by an 
ECO or something).
