Hello people!

We are working on a battery monitor circuit. We are using bq2060a for the same. The circuit has certain Semitec103AT ntc thermistor. due to unavailability of this thermistor, we wish to replace this by NHQ103B375T ntc thermistor.

What factors do we need to consider for replacing one ntc thermistor by another? I know some resistor arrangement needs to be done for this purpose but do not know what exactly.

Both thermistors have data sheets showing the average device response curve to temperature. They may be very closely matched. Alternatively, you could make the change to an LM35. That device has a linear output and requires no correction table.
