Part numbering - Grayhill 71BDF30-01QAJN


#1

What does the suffix Q or P call out in Grayhill part numbers like 71BDF30-01QAJN or 71ADF30-01PAJN?


#2

This is a shortened part number. Grayhill got a new computer system many years ago that would not handle the longer part numbers. So in this case the “Q or P” shortens the number. 71ADF30-01-2-AJN changed to 71ADF30-01QAJN 71ADF30-01-1-AJN changed to 71ADF30-01PAJN
