Is there a pin-compatible replacement for RT0603BRD073KL?

Yes, several 0603 chip resistors are pin-compatible. However, you must verify key electrical parameters like resistance, tolerance, and TCR. For example, RT0603BRD073K3L is pin-compatible but has a 3.3kΩ resistance.

What risks should I check before replacing RT0603BRD073KL?

Key risks include changes in resistance value, tolerance, and Temperature Coefficient (TCR). The target is a precision part (0.1%, 25ppm), so using a general-purpose resistor can impact circuit performance.
