Hi ,

 I saw that the substitute of STR y6766 is TOP257ny, i have a question regarding the pinout, the only diference is that TOP257 is in mirror ?

Regards

they are similar not a direct cross , you will have electrical changes and the pin out changes , I do not see any direct cross for the part.

STR y6766 have the drain at pin 1 and TOP 257 at pin 6. So it is not a 100% substitute ( you don’t remove str y6766 and solder back top 257)

This is a similar cross, not a direct cross, pin spacing is mirrored however the pin out is not mirrored. As seen below the drain on STR Y6766 is at pin 1, while the drain on the TOP 257YN is on pin 7 but the other pins do not follow the same pattern please check the datasheets carefully if using this cross.
