Technetters
 
I have a question for you
 
We are loading a component with a lead diameter of .032 +/-0.002 into a
hole that is .042 +/- 0.003.
 
On page 20 of IPC-2222 it states in tables 9-4 and 9-5 that with a
tolerance of +/-0.004 the max over sizing in respect to the lead
diameter (on the min side of tolerance) is +/-.023.  Can anyone explain
the reason behind these numbers.  
 
We are using an Panasonic AVKII which call for the hole to be oversized
0.019 from the maximum lead tolerance.
 
Why would IPC and Panasonic specs not match, this puts us in a difficult
position.
 
 
Any help would be appreciated.

Thank You
