I have the same issue with the CM650. But i think the answer MAY be that if you have a CM650 black top in good condition, then it MAY fit on this carafe. The issue is really whether the front edge of the top, near the pour spout, moves the little spring lever so that coffee can flow down. Because of the relatively high cost of S&H, I have resisted buying this carafe until I can figure out the answer.
