No. "substitute" does mean remove the old thing and "replace" it with the 
new one. However the order may be different, especially if (as they should 
be) the preposition is different. I think proper grammar is
 	Substitute A for B
 	Replace B with A.
In both of these B is the old, removed item and A is the new, installed 
item ...

I've had to think carefully written this; it must be confusing
for a non native speaker.
