Thermistor replacement for a 100k 3950

I don’t understand thermistor data sheets and am having trouble finding a replacement for what I was told was a 100kΩ β-3950 on Mouser.

This is for a water temperature sensor that typically sees 150*F – 230*F
can I replace it with any 100kΩ ? accuracy isn’t that big of an issue.

hi,:)

Problem with thermistors is that there so many temperature sensitivity curves and if you dont replace the faulty one with same spec the temperature indication could be well out.

Can you post the datasheet for the sick one, someone may suggest a close fit.

I don’t understand these specks, what do they mean?
B0/50 B25/100 B25/50 B25/75 B25/85

That’s all the info the company was willing to give out, no datasheet.

There are to LED’s that light up one “danger” and “hot” I can manually set those so if it reads 10*F hotter or cooler then actual temperature that’s fine
as long as it’s consistent. I would like better accuracy, think I could settle for 10*+- though

The 100kΩ β-3950 is pretty much all you need. Did you check the links I gave?
 
Guess I should have posted not edited

The second link I gave is a part that is 100K at 25 deg C and has a B3950.
