Good day
I have a heater that is driven with a mosfet STD30NF06LT4 which is driven by a MCP14E10 mosfet driver . i could not get the mosfet and selected a HUFA75321D3STCT to replace it, but i am having heating issues. i was just wondering of replacement mosfet i selected was the issue,can some one please guide me accordingly . thank you
see attachment for schematic and mosfet datasheets

Please show your requirements, not inadequate solutions.
Why the mosfet driver if you are powering the driver with 5volt and use a 50ohm gate resistor.
An Arduino pin can do about the same.
The STD30N... is a logic level fet, and might be happy with 5volt drive.
The HUFA75... is not, and can't switch a lot (if any) with 5volt at the gate.
If you want to keep the second fet, then power the driver with 12volt.
