small differences in nominal dimensions of the packages.  One problem is 
that evidentially there is no standard that fully defines what a '1005' 
(aka 0402 in imperial units) package is.

You might get some amusement (or you may be disgusted) from this:

It mentions the lack of standards for SMT resistors but really shows the 
problem with SOT-23's...
