Replacing a TIP112 transistor with a TIP122 transistor should generally be fine, as they are both Da
Replacing a TIP112 transistor with a TIP122 transistor should generally be fine, as they are both Darlington transistors with similar characteristics. However, it's always a good idea to double-check the datasheets and ensure that the TIP122 can handle the required voltage, current, and power ratings of your circuit.
