Goodbye TO92 bipolars. It's been nice.

What is a a distributor that stops stocking something supposed to say other than discontinued?

I suppose it would ideally be nicer to specify "No Longer Stocked" vs "Discontinued by Manufacturer."

Which is exactly what they do: “obsolete” is when the manufacturer obsoletes it. “Discontinued at Digi-Key” is for when they choose to stop carrying a non-obsolete part. jmelson is probably confusing another distributor’s slowness in updating their part status.

The other thing is that DK meticulously keeps manufacturer part numbers separate. So if the manufacturer decides to, say, change from reels of 2500 to reels of 3000, which will have a different part number, then the 2500 will become obsolete even though the part as such hasn’t changed status.

What is the basis for that statement?  Can you link the 'different datasheets"?  I don't see these as anything other than packaging options.

Motorola: http://www.farnell.com/datasheets/1758684.pdf
Fairchild: http://www.farnell.com/datasheets/1880984.pdf

They are similar and both no doubt meet the registered specs of the part number, but on close inspection you may see some differences in typical specifications. Notably, Fairchild has flat beta with collector currrent and it appears to extend down to very low currents. AFAIK technology for that has been developed by the Japanese for analog applications like Hi-Fi and then spread to Korea and Fairchild ended up buying a bunch of fabs there in the '90s.

Exactly. These terms describe the intent in a better fashion.

Replying to my own post here, of course, but...   ::)

What I would really like to see more careful attention payed to is the "superseded by" aspect, which would quite often provide a more obvious path to possible replacements, other variants or substitutes.  (Obviously without getting too far down the substitution rabbit hole like NTE or something, that is...)

Like, yesterday I was looking up the TOP247Y switching controller in my Ryobi P125 charger.  The TOP247Y is obsolete and discontinued so there are none in stock anywhere of course, but when I go back up into the main category and do a complete search, of course I can easily find that the TOP247YN (No Lead, ROHS) is still available just "not recomended for new designs" as there is a newer HX series 257 with better parameters for new designs, but the old series 247Y or beefer 248Y and 249Y are still readily available if I do end up needing to change it out.  There is just nothing on the 247Y page that points me to the 247YN page, which would be a convenient direct link to have to prevent the essentially wasteful time spent sleuthing the other "obvious" variant.

It is very correct and actually critical for them to be careful to not intermingle manufacturers' part numbers which are different whether that be ROHS compliance on the lead finish or lead spacing or reel size or whatever.  Sometimes these things matter and they are not always necessarily equivalent but it would sometimes be potentially useful to have an obvious link to similar familial parts in some cases if implemented properly, especially on "manufacturer discontinued" parts.

Yeah, that I don't understand; if properly placed on the page and maintained with relevant hits, having related links are really effective to increase sales.
