What are the hotend thermistor specs for an MK3(S)?

My hotend thermistor cable broke after a blob of death. I'm looking to replace it now, but I'm not sure what to go for, specs-wise. I'm seeing a thermistor set here that's rated up to 280 degrees Celsius, with a Semitec 104GT thermistor inside. It also mentions setting the firmware code "#TEMP_SENSOR_N 5". What setting do the stock Prusa thermistors have? I'd like to stay as close to factory specs as possible with this replacement.
