Measurements of the superconducting transition temperature, T_c, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous substitution in BaFe₂-(As _1-xP_x)₂. The pressure dependence of unsubstituted BaFe₂As₂, phosphorous concentration dependence of BaFe₂(As_1-xP_x)₂, as well as the pressure dependence of BaFe₂(As_1-xP _x)₂ all point towards an identical maximum T_c of 31 K. This demonstrates that phosphorous substitution and physical pressure result in similar superconducting phase diagrams, and that phosphorous substitution does not induce substantial impurity scattering.
