Abstract: The recent experimental observation of the substitution of praseodymium (Pr) in high transition temperature (<i style="">T</i><sub>c</sub>) superconducting Y123 compounds gives rise to very interesting properties, such as monotonic decrease of <i style="">T</i><sub>c </sub>with increase in Pr concentration which is not satisfactorily explained yet. The depression of <i style="">T</i><sub>c</sub> is due to hole filling/hole localization, magnetic pair breaking or some kind of disorder/dislocation is still not clear. The depression of <i style="">Tc </i>in Y<sub>1-x</sub>Pr<sub>x </sub>Ba<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> has been explained using magnetic pair breaking, hole filling and disorder. It has been argued that the disorder along with hole filling is responsible for suppression of <i style="">T</i><sub>c</sub> and subsequently to lower order parameter (∆).
