Rds is a moving target, it goes up with increasing current and down with increasing voltage so at 2 A it might not be far from the 70N02 at 7A but we won’t know until testing. The listing I saw showed 18mOhms at 4.5V and 20A draw for the big FET. The gate pin matches up but the drain is in the middle and source is on the left and big tab so it’s close but not quite.
The 10.5 mm and 12 mm boards are available from Oshpark and are 1.6 mm thick. I still have some of the 10.5 mm boards that are .8 mm thick.
