Using MOC3022/MOC3023 instead of MOC3020 Optocoupler

I am planning to make PID temperature control AC 220v Nichrome coil heater. I have seen lots of tutorial videos & everyone is using either MOC3020 /MOC3021 optocoupler to detect the zero-cross, measure the temperature, calculate the delay of the firing pulse with the PID control .But unfortunately these two components is not available in our country . According to data sheet the only difference is LED trigger current. So my question is , Can I just use MOC3022 / MOC3023 ? Do I just have to change the resistor to use these components?
