My Samsung galaxy F12 mobile is not getting charged with own charger

@madmax94338 "charged with only one another charger" means you've tried multiple chargers. You need to let us know what the voltage outputs on those chargers are. In particular, we'd be interested in the voltages for the one that works. Also, there is a possibility that (if you tried other chargers) the USB-C port is having issues. Double check for that as well.

@madmax94338 this sounds like a daughter board issue. That is your charging board. Something like this one

If that doesn't change anything, follow the Samsung flow chart and measure the components accordingly. The components are the ones the blue arrows are pointing to.
