Suggested component alternatives

[PetteriAimonen]

Some of the parts are not available on e.g. Digikey.
Here are some alternate components in case someone finds it useful:

• Pushbutton TS24CA can be replaced with TS31-46-35-BK-B-260-RA-SMT-TR
• LED driver FAN5331 can be replaced with TPS61040DBVR
• Battery charger ME4055-N can be replaced with TP4057
• USB connector KH-TYPE-C-16P can be replaced with U262-161N or USB4105

Thanks @PetteriAimonen - that's super useful.
Do i understand it right - since JLCPCB doesn't have FAN5331SX I can replace it with TPS61040DBVR without other modifications? Are they pin compatible, etc?

[PetteriAimonen]

@TapuGithub They seem compatible to me, but I haven't received my boards yet so I'm not 100% sure it will work. At least the pinout, feedback voltage and suggested schematic look the same in the datasheets.

Great! Thanks @PetteriAimonen! If you don't mind let me know when you'll be done with testing. I'm hesitant to sped 200$ on boards with unknown result and no way to fix it.

@TapuGithub I assembled two units now with the part replacements I listed, they seem to work perfectly!

Thanks, ordered my batch with TPS61040DBVR.
