Even with the same manufacturer, a part may be moved to a new process changing its unguaranteed characteristics significantly.
Subject of the new topic: I do the same thing when drawing up parts lists and spend some time qualifying alternative parts and sources. I’m guessing that at switching speeds, the load capacitance was enough that it was necessary to have indefinite current output from datasgeet buffer.
Unfortunately I don’t have any references. Do you have a reference for this? If you used, say, ait would be made by one of those manufacturers. Thursday, October 31, 9: I doubt Tektronix was pushing the edge so much as just running their own quality control program on incoming parts.

The characteristic curves for old parts and new parts like the 2N could be compared to see if the processes was changed but that will not be reliable if newer published data was not updated to reflect changes.
This cannot be undone. OnSemi makes some inferior versions of some transistors, Fairchild makes other inferiors of some other transistor. I’ve got a few NOS if anyone needs a replacement. At the same time, tubes were still used in this scope, so perhaps Tek was really pushing the edge at this time and it makes sense they may have selected their transistors in order to do that. The parts list in the service manual says “Selected from 2N”. The difference between two different part numbers may be just the time spent on the automated test equipment which directly translates into an additional cost of tens of cents per second.
This is great, since the BC is a sort of rugged monster of a TO, and it even has a complementary part. Parts made in different factories can very well be different. I was not able to find any current Fairchild process documentation. I spent all night studying the LT and LM and that leaked over into seeing Q as a current source instead of follower: On Thu, 31 Oct The Group moderators are responsible for maintaining their community and can address these issues. The 2N looks like a good bet.
What are the odds that Fairchild is still using anything approximating NS Process 12? My sources are of an anecdotal nature, so I mostly consider them as indications I should do my own tests. At any rate, do compare datasheets between manufacturers. You can reject cookies by changing your browser settings. Friday, November 01, I found some audio related discussions about matching between Fairchild and On Semiconductor BC and BC series transistors which mentioned the large Ft variation but nothing detailed.
I’m very hesitant to use this part number in any design for that reason, as it’s likely builders will just use whatever is available at the cheapest cost.

Here is data on the 2N which matches the specifications Tektronix gives for the Click here to access our new inquiry page. Almost all of the transistors in the parts list dataseet selected. Other transistors are marked “Replaceable by” or just list the non-Tektronix part number. The data I have on the calls it a “bulk” device.
I sure can because a quick search turned up a good electronic scan of the paper National Semiconductor Discrete Databook that I have although mine may be a slightly different year: Actually, this circuit is a class AB follower.
In a triggering circuit I’ll bet 2b3251 could cause all sorts of weird behavior.
