CY22150FZXI is the replacement, device webpage - https://www.cypress.com/part/cy22150fzxi
The only difference is CY22150FZXI is lead-free(the letter X indicates lead free) while CY22150FI is leaded.
For your more reference.
Usually,Cypress device replacement information is provided in PCN - https://www.cypress.com/pcn/
Take CY22150FI as an example:
When you search CY22150FI in https://www.cypress.com/pcn/ you will find the repalcement for it is CY22150KFI from PCN084725 - https://www.cypress.com/documentation/product-termination-notice-ptn/pcn084725
You will find CY22150KFI is EOL, search in the ECN webpage using CY22150KFI as keywords, you will find CY22150KFZXI is the replacement as lead free version for CY22150KFI from https://www.cypress.com/documentation/product-termination-notice-ptn/pcn115096
CY22150KFZXI is EOL again and the drop in repalcement is CY22150FZXI per https://www.cypress.com/documentation/product-termination-notice-ptn/ptn145300
Ok, I got it
It's very helpful.
This part number is so special that EOL has been replaced for many times, so that I suspect I made a mistake in finding the method
