Complaint pins has a hole (opening) in the middle
on the insertion portion of the pins so it can compress more and
cause less damage to the barrel in the board. Non-compliant has a solid
base so there is more chance the pins will dig-in and damage the
barrels. The hole size has to be more exact for Non-compliant pins. Hope
this
helps
