Trying to repair a Hyperkin Duke Xbox controller where the left trigger doesn't respond. Found that the resistance of this potentiometer doesn't change when it's moved, so I'm looking to replace it. I'm a novice with this stuff though and I'm having trouble identifying it. Any help is appreciated.
How many pins does it have in the circuit board?
Someone said it might be an encoder but I see "103" on it which is used on potentiometers to indicate 10k ohm (10 x 10^3)
It has 3 pins, and I found that it's a linear (B), 10k ohm (130, as you said), potentiometer. I found similar ones, but the 9 and 5 at the top concern me. The others that I found have a 60 and a 6 there instead.
Linear checks out for this kind of application.
Potentiometers are pretty basic things. About the only thing I can think of that would be specified electrically is value (10k), wattage rating (but I doubt much current is sent through these in this application), linear/logarithmic taper, tolerance (often 5%, or 10%) and maybe the type of contact/track or something (probably doesn't matter).
Those numbers could be manufactured date or lot codes or similar.
How does the thumb "wheel" attach? Or is it built in? I can't tell from the single pic.
Other things to consider are the pin spacing and physical dimensions.
