Laptop SODIMM - what is up with these part numbers!?

The sku mentioned on this ZZF link is not the same as the model number if you run through the Crucial.com memory finder.
Similar story with this Kingston at newegg for $315 The numbers don't match up with results from the the Kingston.com memory finder.

EDIT: ARE THEY COMPATIBLE?

I was looking for HP zt3000, should be the same as for Compaq x1000.
