PULSECODER

Dear All ,
I've just a question .
lately my CNC lathe z axis servo motor has been defected .
since , I have several same machine I succeeded to find that PULSECODER is broken by changing the parts one by one with each other .
when I changed the pulsecoder of defected machine with another machine the problem has been fixed .
now I have a pulsecoder in my warehouse with this part number : A860-0365-V501 ?I64 Whereas the original one was A860-0360-V501 ?A64 .
I don't know are these compatible with to gather or not .
please let me know your idea .

thanks a lot ,
