Need PDTA114 transistors

[Jim]

I need a source for a small quantity (20 or 30) Phillips PDTA114YS
transistor for a small VHF transmitter project. It is evidently an obsolete
part, and I don't find an equivalent part . Here is the data sheet, in case
anyone is interested:

This TO-92-3 transistor has an internal bias resistor, but I am unsure what
makes it special other than that.

Any help would be appreciated.

Look for DTA114Y parts.

Well, gee. The DTA114ysa does seem to be the substitute, but there doesn't
appear to be a source for that either, unless I need a few thousand.

Thanks

Maybe Patrick will show up.

So if it's an obsolete part, why do you want it? The only good reason is
as a replacement part, otherwise find other parts.

In your case, if you're building from some old schematic, you find one
that uses common parts so substitution is easy, or you find a more
recent schematic that uses parts that haven't gone out of style.

There is nothing magical about most schematics. Name any project, and
likely a long string of similar projects were published. Few are unique,
while plenty will be difficult to build up because they do use
special parts.

Look there, in the PNP section.

what you're looking for is a digital PNP transistor
with R1 =10k and R2=47K if I remember..

19 cents shouldn't break you !

Other companies make these devices. Rohm and On-semi come to mind. I think
Farnell may even stock some.

Look for 'digital transistor'.

Very good!, I don't know why Mouser stuff doesn't come up on a Google
search, but I found what I need at Mouser.com

Thanks

FWIW, here is a UK source for the leaded part (DTA114YS):
