    TCP8127 is a P channel fet and you can replace it with 4407/4835/4409 or similar mosfets.
    Bq737 you can replace with BQ727 or BQ07A

            I know this post is kinda old.
            Replacing BQ737 with BQ727 will make charging slow. BQ727 does not support Boost Charge (mode). HPA02224 is a better alternative.
