Rahman, The Sony kss210 series I know can be interchanged, with the only difference being their physical parameters. And kss213b and c are likely interchangeable for the same reason, although you would have to research their Sony part numbers a little closer for the particular application you're repairing. (Sony part numbers: 8-848-379-31 and 8-848-482-02, respectively) You might want to contact someone like Studio Sound and ask Frank Fendley. Their site is: http://www.iglou.com/studiosound/ and they do sell Sony laser pickups... Hope this will help...
