Hi,

I need some technical assistance on PC844A and PC844, The only difference in both the parts is CTR (Current Transfer Ratio) as per datasheet.

PFA!!

I want to know whether we can replace PC844 with PC844A??

Does the circuit works fine?

How to proceed if we need to do any analysis?

Please share any reference technical documents if you can.
