You'd really hate working in aerospace where every part, COTS or not, is effectively the same way.

I really get annoyed when I see things like "MJE371K? selected" in parts lists. HP, Tek and even Heathkit has lots of them with separate numbers. Problem is that they never tell you what it is selected for such as gain, leakage, input capacitance, or maybe frequency response. Worse is that the selected part might actually be a non-selected off the shelf part which might be more expensive or harder to get. Decision might have been made by a parts buyer controlling costs. Really makes repair tricky.? It would be nice to get scans of the microfiche for the selected parts so we can see what they were selected for.
Just my opinion here...
