The SKU is uof debatable use - they're for vendors and suppliers ... so that they can place orders without the OEM havng to give them the part number (so that they can't undercut the OEM by selling equvalent parts cheaper).

You want the part number, to be sure.

Otherwise though, you need to check who supplied the module and/or the OEM - they're the only ones likely to be able to do anything with the SKU.
