Fortunately ON Semi has introduced a number of new ones that are equivalent or even better, apparently from an old Sanyo process that nobody knew about. The CPH3910 is about 1 dB quieter than the BF862, but has higher I_DSS so it doesn't run as happily at 0V G-S, which is often a convenient point. On the other hand its zero-drift point is in the low noise operating range.
Between the two types I have about 40,000 in stock, so I'm good for awhile.

That's one problem with making lifetime buys of valuable components. You stop buying anymore, contributing to the declining-sales problem.

Well, I bought all of them in the last couple of years, so I plead not guilty. ;)

Or he could make a mini-fortune selling small pacels of them on ebay.
you could use the same as an argument for subscription based software
They also tend to age. It's probably not all that important for small/specialty users/applications but it's not a good thing for volume production. Even I will throw reels away after a few years.
what problems does that cause?

Solder-proof leads. Water is often a problem, too, but can be dealt with for longer than a couple of years.
thank you, glad to see it's nothing more serious
