    I came across this schematic ( to build a CASIO DATA cable for calculator CFX9850.

    Everything seems to be in the right order. Except the MOSFET transistor. One site ( suggests to use ZVP 3306 or VP0106 (altough it tells the model as SiVP 01069602).

    I can't find any of these in my location. Is there any equivalent easier to find?.:confused:

    Bellow you can see the schematic. Middle, Bottom and Tip, are Ring, Base and Tip in 2.5 mm audio plug.

    Best regards~
