Based on the information I was able to find on your Demco DA603 it appears the Dexter DX7.5L A-60 Brake Actuator for Drum # DX83FR or Disc # DX56FR brakes is going to be the best replacement. The disc brake actuator includes an electric lockout while the drum brake actuator would require a Lockout Key # DX94FR if you do not have free backing brakes. Both these have a 2" coupler and are rated for 7,500lbs to fit on a 3" by 5" trailer tongue.
