Is there a pin-compatible replacement for ARG03DTC1000?

Yes, RT0603BRB07100RL from Yageo is a strong candidate for a pin-compatible replacement. It has the same 0603 package, pinout, resistance, and power rating, with the added benefit of better precision.

What risks should I check before replacing ARG03DTC1000?

The primary risks are electrical. When replacing a precision resistor, you must verify that the substitute's tolerance and Temperature Coefficient of Resistance (TCR) meet your circuit's requirements. Using a part with wider tolerance or a higher TCR can degrade performance and stability.
