jfet j309 by Interfet

I am building the Fumble boost. I need to know how to read the jfet pins on the schematic.

Interfet n-channel j309 data sheet has
1 source
2 drain
3 gate

How does one determine the jfet pinout on the schematic?
Is it safe to assume schematic is
1drain
2 source
3 gate?

thank out

The Drain and Source are interchangeable so it's a direct fit, but you are correct about the PCB pinout.

Interfet's datasheets have caused this confusion before with the J201.

Correct.

Thank you, l. google has a lot of contradictions on jfets!
