Hello, I apologize for if breaking any rules for this question
I am looking for a transformer 220v to 5v 1A for my pcb, I searched for weeks but I could not find a suitable one, so the transformer should be in smaller dimensions due to the project that will be implemented transformer , If anyone can help me with any model or something
Thank you

Did you look at all the major electronic distributors? Digikey, Mouser, lots of others.
If you can't find a transformer, I wonder at your experience designing printed circuit boards using mains voltage. Personal safety is pretty important.

Not surprised. That's a 44:1 ratio.
Did you try Digikey?

I assume you are looking for a "DC power supply" (which is a transformer plus additional components).
A "transformer" has AC input and AC output. A switchmode power supply can use a smaller transformer (for the same current) because it operates at much higher frequency than a transformer running directly from the 50/60Hz power line.
So, you might find a power supply that's smaller than a transformer but the additional components add to the overall size.
If you are looking for 5V 1A DC pcb mounted power supply - https://www.newark.com/w/c/power-line-protection/power-supplies/ac-dc-converters/ac-dc-pcb-mount-power-supplies?output-voltage-output-1=5v&output-current-output-1=1a
I'd recommend this

or one similar, like those shown at Newark.
