If it was replaced by a ford dealer, under warranty, yes it is stock. There is no official factory 'Upgrade' to the EGR cooler, they just put another of the same one on. The Square body means it is the later version, as the earlier one, used in '03 only IIRC, was round. In Ford's defense, the problem isn't the cooler itself, it holds pressure just fine at it's designated operating temperatures and pressures. It merely is one part that suffers due to a much larger problem. Fix the larger problem (Coolant Silicates clogging the oil cooler), and the Stock EGR Cooler works perfectly fine, and will not fail under normal usage.
I hope they flushed your coolant system and replaced your oil cooler (in that order) when they replaced the EGR, if not, they'll be doing it again quite shortly.
If you want to upgrade it, you can either delete it in some way, or replace it with a BulletProof Diesel EGR Cooler, which is specifically re manufactured to hold MUCH higher pressures without problems.
There are a few different ways of deleting the EGR cooler. Mine was done via welding the scoop in the up pipe closed.
The solution to the overall problem, is to change to a coolant that doesn't gunk up the oil cooler.
