Is there a pin-compatible replacement for RT0603BRE0780K6L?

Yes, several 0603 package resistors are pin-compatible. RT0603BRD0780K6L is a strong candidate. Other parts may have different resistance or tolerance and require engineering review.

What risks should I check before replacing RT0603BRE0780K6L?

Key risks include changes in resistance value, tolerance (target is ±0.1%), and TCR. The target is a precision thin-film resistor; using a thick-film part will increase noise and reduce stability.
