I am planning to use MT3608 schematic for my project to boost the voltage from 3.7V to 5V. I am planning on making a customized PCB with all the requirements that are needed for the project.
In the MT3608 module, which is available mostly in the outside market, the inductor used is 22uH. Below are the MT3608 module and the Inductor component that is used in the MT3608 module.
Link to the Inductor component
However, it is difficult to procure this component as it is not that frequently available everywhere.
In the datasheet, they have mentioned the inductor specifications as seen in the image below.
Can I use any other Inductor of same value of 22uH? Or is there an exact alternative that can be used for this component?
It will be helpful if I can get a component that can be used instead of this one.
Thanks in advance.

No -- in fact, that "Inductor Selection" thing that you quote is pretty specific that the series resistance and core loss matter, as well as the inductance.
The three things that matter the most are the series resistance, the core loss, and the saturation current. If you can get your hands on a datasheet for that inductor, then go looking for inductors available more locally to you (i.e. TDK, MuRata, etc.)
If you have a favorite distributor, look through their catalog. Chances are that an inductor in the same package with the same value will work, but you really want to double check the specifications.
