All cabin door are identical
Except for the loading. All doors see cabin pressure. Over wing doors additionally see the low pressure of the wing upper surface, hence they are higher and more dynamically loaded. On the other hand the overwing structure is much stiffer, so mainly the aft fuselage doors see the highest deformation of the surrounding structure and hence the highest realtive movement of the door stops and locks.
Therefore the doors may look identical, but might have small differences in wallthickness or dimension of internal structural items.
