L-Adapter

Good morning,
I would like to create a psu with the L-adapter schematic for a Raspberry PI4b, could you please help me in choosing alternatives to the NJW0302G and MJE15030G transistors, as I can't find them?
If I use single LEDs instead of the LED bar could I run into problems?
Thanks so much for your help.

You would likely need a small number of LEDs to reach 5V with a little help from the trimmer. You could try TIP2955 and BD243C. Same size but not directly equivalent spec parts, it will possibly work on those too, but no guarantees. By the way, the MJE15028G is also applicable as it is just an 120V rated MJE15030G.
