66140CBI vs. 66144CBI

Did some searching, and from what I could find, people were suggesting the DS1 bulbs to get were the 66144CBI's, however that model # doesn't show up on Osram's website, nor over at TRS, the only CBI available is the 66140. Is that just an updated # and essentially the same thing?
