Teufel One S searching for unknown part.

Hey Guys,

I`m currently trying to repair a Teufel One S speaker.
I think i found the defective part, but can`t find something when searching for the part marking online.
The part has the marking 4202 and is 3mm on the longest side.

The same part beneath the part im searching is functional:
Pin 1 is down left.

Pin 3: 24V
Pin 4: 2.2khz
Pin 5: 6V

Also soldered to the PCB are:

40P13S MOSFET (Power Rail MOSFET i think)
TPA3118
AUDA1701
STM32

Can someone please take the time helping me find the part number?
