What is the difference between TQFP44 adapter SA245A and QFP44 adapter SA675?

They have the same pin-outs, but different in height. SA245A is used for thin (ceramic)
QFP and the thickness of the IC is about 1.4mm. SA675 is used for Plastic (thick) QFP
and the thickness of the IC is normally more than 2mm. One chip will not fit into other
adapter due to height difference.
