@alejandrod I’m afraid Face ID won’t work if this part is replaced. As stated in the introduction, this component is paired to the logic board from the factory (similar to the home button on earlier iPhones). Currently, if you need to replace this part, you’ll have to sacrifice Face ID, or else pay Apple directly to perform the repair. (They have a software calibration tool that pairs the new part to your phone to re-enable Face ID, but they don’t share it with anyone outside of Apple.)
