ALPS 2.1K Potentiometer <br> The OEM side trim pot resistor was made by ALPS. It fits PS5 DualSense and some rare PlayStation 4 DualShock 4 wireless controllers with 2.1K ohm ALPS joysticks inside <br><br> <b>Solve most of joystick problems: <br></b> 1.According to some estimates, 80% chances of joystick problems were caused by the potentiometer. In another words, the rotary mechanism and the tactile switches are not the problem. You can simply replace the side potentiometer sensor alone to solve most of the problems<br> 2.De-soldering the unit with only 3 prongs will be much more easier than replacing the 14Pin joystick assembly <br><br> <b>Compatibility Notes: <br></b> 1.ALPS version is not interchangeable with the orange version made by Favor Union<br> 2.ALPS potentiometers come in two different resistance values. Never judge its value by its color. Please make sure the resistance value is 2.1K ohm before ordering<br> 3.Please choose 10K ohm for most PS3, PS4 DualShock 4, Xbox One, Elite Series 1 and 2, Xbox Series S|X and Switch Pro controllers <br>
