| You happen to have chosen an example that really winds me up. EMI emission testing of individual part is fairly meaningless unless you don't intend to connect anything up to it. The only meaningful way of testing EMI emission is in an entire system. It is quite possible to throw together a bunch of components that pass EMI emission testing on their own, and end up with a system that will fail EMI emission testing. Likewise, it's quite possible to build a system with components that fail EMI emission testing on their own and end up with a system that will easily pass EMI emission testing.
Secondly any change in the components (even if it's just a connector) on the board, despite their supposed equivalences, can be sufficient to change the EMI emissions profile of a board.
I note there's no comment on EMI acceptance...
