HP transistor 1853-0357 substitute / replacement?

[TourEasyPilot]

Anyone know of a substitute or replacement for
an HP PNP transistor, part number 1853-0357 ?

It may be a special version of 1853-0218.
How about a substitute or replacement for that one?

Thank you!

From a large HP X-ref that I have:

1853-0218 03406 NS65098

1853-0357 no info

03406 is the mfg. I don't recognize teh part number.

Hi,

As you can see it's not on the list that you can find here:

It's possible that the Nat Semi 65098 might refer to a wafer process
number and package code.

Wafer process #65 produced PNP devices for high-speed saturated
switching applications up to 50mA.Typical commercial type numbers are
2N5771 (TO92)

I've no info on a process 98.

The internal package code '98', however, specified a TO3 outline.
" " " " '65' specifies 14pin DIP ceramic.

Strike three......

Thank you!

Try a 2N2894 - DOD's FEDLOG lists this as a possible substitute for
the 1853-0218 and -0357device. PNP Silicon, TO-18, RF/AF Amp.

Cheers,

your best bet is to chase the circuit and draw a schematic of sort and then re-submit all transistors can bee replaced by something even better as soon as we know what it does with what kind of voltage there is.
