Yes, the ML920S/DN works fine.? It has the same surface mount tabs as the /F9D.? The only difference is the coin cell has an insulating wrap around it, which is fine.? The price at digikey.com is $2.18 USD, quantity 1.
Just be carefull not to short the leads together when handling.? Use ESD protection when handling any PCB, but especially the Logic board.
