I'm building a circuit that calls for a dual monolithic

so they end up at the same temperature.


Yes, you can but the closer the match the better.
Two parts form the same lot/datecode with the same
IDSS should be ok.

I've done this with MPF102s (a wide tolerence part)
with good results in all but extremely critical designs.
