Please help me find the SMD code 12p and 1ss i think they are FETs the way they are used in the circuit, package is SOT23
kind regards

The nearest I could find was Rohm DTA123 which is marked 12 but is a digital PNP. I don't know if the add the "p" as a date code. For 12p I can only find a 5 pin SOT-23 device.
Similarly for the 1ss - only 5 pin SOT23. There are devices with 1S but no 1s or 1ss in SOT23 that I can find.
They are always tricky. The codebooks don't contain everything, unfortunately.

If you can find out what the device needs to do then replacement probably isn't that difficult. Most SOT23 MOSFETs follow a standard pattern of connections.
The only transistors starting 1S in SOT23 I found were MMBT2369A, MSC3130 which are NPN and UNRF1AM, UNRF1AT which are Panasonic digital transistors. They aren't markedd 1SS though, as far as I can tell.
