Yes there is, the first part (in this case MS-012) specifies the package wi=
dth and pin spacing (in this case it is a 0.3" package with 0.05" pin spaci=
ng), and the second part specifies the number of pins, here AA is 8 pins, A=
B is 14 pins, AC is 16 pins.

MS-013 is the 0.4" package, and IIRC AA is 20 pins, AB is 24 pins, AC is 28=
 pins.

I think the situation does change once you go to the square packages, but I=
 haven't had much to do with those.
