Pioneer DDJ RR Spare Parts

Hello team, I have to change a module of the pioneer ddj rr (PNL1 DWX3896) and since it is discontinued it is difficult to find it. As the pioneer ddj sr2 is very similar, could it be replaced by the module (PNL1 DWX4121)? Is the module (PNL1 DWX3896) the same as the module (PNL1 DWX4121)?
