XPS Studio M1640 Motherboard Compatibility Y503R vs. Y505R

Hey guys, I've been trying to get a motherboard replacement for an old XPS 1640.  The current board is a Y505R, DA0RM3MBAD0.

There appear to be very few Y505R boards, but have found several Y503R, with model DA0RM3MBAD0.  I am getting conflicting feedback from sellers on the compatibility and differences between the two and have not been able to find out what is the real difference.

Thanks in advance for the feedback.

The two are functionally the same.

Thanks ejn63 for quick response!  Much appreciated. Any idea why different part numbers?  I know it will fit the chasis but I will be using all the removable components from the old board and want to be sure I don't have a problem.   This was bought in Singapore while I was there on assignment.  Curious if this has something to do with Asia vs. US, etc.  I'm just surprised there is almost no mention of what the differences are in any forums or elsewhere online that I have been able to find.
