Is there a pin-compatible replacement for RT0402BRD0780R6L?

Yes, several 0402 package resistors are pin-compatible. However, none match all key electrical parameters. Review of tolerance, TCR, and resistance value is critical.

What risks should I check before replacing RT0402BRD0780R6L?

Key risks include changes in circuit accuracy due to different resistance values or wider tolerance (±1% vs ±0.1%), and performance drift from a higher TCR (100ppm vs 25ppm) or different resistor technology (Thick vs Thin Film).
