    hello

    i need help with datasheet comparison. i need to use a KN 2222a for a high power voice transmitter circuit. but, that transistor is not available. so, my vendor told me to use 2N 2222. is 2N 2222 equivalent to KN 2222a? i have used 2N 2222a but the output power is less. i am enclosing the datasheets for the above two transistors. please tell me if they are similar.

    what are the significant parameters? If you know them and have the data sheets, surely you can see if the devices are equivalent?

    Both transistors have a wide range of current gain. Maybe one is low and the other is high. Maybe one has a much higher transition frequency than the other.
    Transistors with the same part number would have the same difference in performance.
