    have you started by checking the datasheet for each device?

    you should be closely matching all parameters if possible - try to filter using digikey.

    filter for the original device and see what other ones make the cut.

    it is also impossible to tell you without knowing how the device is being used (ie - surrounding circuit)

    Well, there are cross reference sheets that could help.
    I don't have one you need.

    The datasheets should be all you need.

    As far as I can tell the 2N2322 has a lower Repetitive Peak Reverse Voltage/ VRRM 25 Volts.
    The 2N1595 is rated at 50 Volts.

    The 2N1595 SCR may or may not be able to be replaced by the 2N2322 type, depending on your circuit and operating voltages. As was said earlier, the main difference is that the 2N1595 has a Repetitive Peak Reverse Voltage/ VRRM of 50V whereas the 2N2322 has a lower Repetitive Peak Reverse Voltage/ VRRM 25 Volts. However, the 2N2323 has the same VRRM as the 2N1595 and therefore, you can replace the 2N1595 with the 2N2323 type. They both have the same metal package, TO-39, and all the characteristics in the data sheet posted are the same. Now, it is possible that there is some obscure parameter that may be different, but all the specs given on the datasheet by Central Semiconductor ( are exactly the same. Samples seem to be available on their website and are normally free, except possible for shipping charges.

    Good luck.
