Ask everyone, if the optocoupler 817 in my circuit diagram is changed to 816, what will be the impact? What is the difference between the two.

The withstand voltage Vce0 of the output part of PC817 is 35V.
The withstand voltage Vce0 of the output part of PC816 is 70V.
Their CTR is 50% minimum and 600% maximum.
Can be used instead, the main difference lies in the individual CTR value.

There is no problem with this. I used it once in an emergency.

There should be no difference, but the voltage and current details are a bit different. You can check the parameters for details.
