'00 GM Blower Motor Resistor

Hi
I just replaced the blower motor and the blower still does not work.
After reading the forum my next step is to replace the Blower Motor Resistor.
The current resistor has a part number of XW1H-19E624-AB.
Autozone carries a replacement part made by Duralast for $88.

I would prefer an OEM replacement, but the one I located from the internet starts with different 4 digits. 8W7Z-19E624-A
$71 with shipping

Are these parts interchangeable?
Thanks for your help.
