Revision vs. Version Part Numbers
Moving forward, the Service Parts database will identify
service parts (upgrades, changes, or variations) with the
word Rev. (Revision) or Ver. (Version) appended to the part
name.
For example:
661-2193 Card, Processor, 333 MHz, Rev. 3
661-2113 Board, Logic, iMac, Ver. 2
• Revision (Rev.)= A change or upgrade to the part. The
new Rev. is backward compatible and will eventually
replace the earlier part number.
• Version (Ver.)= A different variation of a similarly
functional part. The versions are not interchangeable.
