more electronegative element occupy axial position in sp3d hybridisation .  , and the reason lies in the structure only , 
in the case of PF2CL3  the dipole moment cancells out but in the case of PCL2F3 , the dipole moment are not going to cancell out . 
for the structure , look at the ncert textbook ,
