I have a need for obsolete Altera EP1810GC-35. I have stock available with Altera trace to P/N: EP1810GC-35AB. Can anyone explain what the "AB" call out is?  

 Thank you for your help!

I found a couple of old datasheets. There are two packages for that device a PGA and a PLCC, but I did not find a "Ordering" information sheet that said what the part numbering scheme was. 

 I did find a supplier that apparent has the license to continue building these parts. Rochester Electronics: http://www.rocelec.com/obsolete-semiconductor-manufacturing/featured-product/?f=ep1810gc-35  So you might want to contact them to see if they have a better idea.  Pete

I'm having a heck of a time finding out what the "AB" calls out. Here is a photo of what I have available.
