Yes if you see M542 in the part number it's the same thing.

D.C. mentioned the motors from CNC4You, which are good however their drivers and PSUs are not the cheapest. There are plenty of eBay sellers with good prices for the drivers. For £350 you should be able to get four 3Nm motors, four 80V (e.g. DQ860MA) drivers and a suitable PSU. With a 600mm Y-axis you would be better off with two motors and leadscrews/ballscrews to prevent racking, or one motor and a long belt to link them.
