I am replacing a GFI breaker. The old breaker has 2 white wires (one
striped). The new breaker has only one white wire.

Is the new breaker compatible?

If you at the electrical service then the two wires end up on the same bus
the neutral/ground bus.
If you are in a sub panel then the two wires would go to different buses.

If your breaker is made by the same company that the panel is made by your
fine. I am not a fan of mixing manufactures.
