I need a 2sk170 jfet for a project. it seems to be discontinued. does anyone know of a substitute that would be in stock at digikey.com? thank you.

Hello,

Do you have a schematic where this 2sk170 is used?

Wich version of the 2sk170 do you need?
There are three versions:
GR : Idss 2.6 - 6.5 mA
BL : Idss 6.0 - 12 mA
and V : Idss 10 - 20 mA
The letters stand for the colors on the top of the FET.

PS I have attached the complete datasheet for the FET

the schematic is located here:

It is an auto wah effects pedal. one schematic calls for the 2SK170 the other layout calls for a 2N5457. neither of these are in stock at digikey.

Hello,

Looking at the 2N5457, you need the an FET with a low Idss at Vgs=0 Volts.
See the datasheet of the 2N5457.

Using the parameter search to digikey, you might find something.
