Hi guys,
my force sensing resistor sensor I use on my DIY ribbon controller has died. The Eowave which sold all kinds of sensors already wired to 3.5 STEREO jacks (which then go to my Eowave EO-311 SENSOR TO CV module) stopped making them.
Now I have to make my own connections to the sensor now which is probably a piece of cake but I am a complete noob in electronics.
So I took apart the cable which Eowave provided and found this little thing inside:
From my very limited understanding would this wiring look something like this:
Am I getting this right? Am I right that this SMD resistor 5102 between inputs V+ and V- on the board is the same as 51kΩ resistor between ring and ground on my picture. Would 50kΩ resistor also work?
Many thanks for any help since I am completely lost beyond this point.

Power rating (besides for power rating) also usually = Size. The higher the power rating usually, the larger the physical resistor. I'm guessing you don't need anything crazy and 1/4 watt is the defacto rating for most DIY throughhole projects. You could certainly go smaller, but im not sure what the power requirements of your ribbon controller are.
SMD is usually much lower tolerance level than through hole so I would get a 1% transistor.
Mouser: 1/4W, 1%, 51k axial (through hole) resistor

You could also look at the smaller wattage versions:
