# Thévenin equivalent with a dependent source

I'm working in a circuit with some switches and it has the same configuration but different elements between ab. I am not sure if is possible to get a Thévenin equivalent of the next strange subicircuit to simplify calculations:

Since $i_x$ is not associated in any way with the output port AB, $i_x$ is an independent variable and thus, as seen from the port AB, the CCVS is an independent source. The Thevenin equivalent is:
