What risks should I check before replacing SDNT1608X103F3450FTF?

The main risk is the difference in the B-value constant, which defines the thermistor's resistance-temperature curve. A mismatch can lead to inaccurate temperature readings. Always verify the alternative's R-T curve against your system's requirements.
