    what is the difference between 4N25 and TLP521??
    Can I simply use 4N25 instead of TLP521

    Most probably, but what is the exact nature of the application?
    One is 6 lead the other 4.

    If the 4N25 meets your circuit requirements, then yes.

    Hello,

    If you can use the TLP521 in stead of the 4N25 depends on the used circuit.
    On the 4N25 the base of the output transistor can be used.
    The breakdown voltage of the 4N25 is higher as that of the TLP521.
