There is some rhyme and reason to it. No dates were encoded.

XXX is usually a class of component, XXXX is the model number, and the
-XX suffix would be the revision to that board/component.

Hardware prefixed with 501- were usually system components that could
be ordered, stuff like system boards, etc. For instance, you could
have a Sun Enterprise System Board which was listed as option X2622A
was also known as 501-4884. That board would have different revisions,
like 501-4884-01, -02, etc. Individual chips would sometimes have a
370-xxxx number, but they'd be a part of a kit, which would be a
501-xxxx number. 64M would be spaced across 8x8M DIMMs. AKA X7021A aka
501-2652. Each individual chip may have a 370 or 501 number (I

Some individual memory components and upgrades had 370- prefixes. For
instance, memory upgrade kits for an Ultra 5 are prefixed with

540-xxxx are usually hard drives. 300-xxxx are usually power supplies.
Documentation/booklets seem to be prefixed with 805-

Also, found a mirror of Sun's old-school website:
