Best Alternatives to RC0603FR-0776K8L

Package: 0603 (1608 Metric)YageoChip Resistor - Surface MountSeries: RC_LPackage: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Resistance: 76.8 kOhmsTolerance: ±1%Composition: Thick Film

Finding a substitute for the Yageo RC0603FR-0776K8L 76.8kΩ resistor involves balancing resistance value, tolerance, and technology. Several parametric alternatives exist but require careful engineering review.

AI replacement insight

Electrical riskhigh

All candidates have different resistance values and some have different technology (Thin Film vs. Thick Film).

Package risklow

All recommended candidates share the same 0603 package.

Sourcing risklow

All parts are from major manufacturers and have an Active lifecycle status.

Can it be replaced directly?

No, a direct, 1-to-1 replacement for RC0603FR-0776K8L is not available among the candidates. All options are parametric alternatives requiring review.

Best replacement path

Select a candidate based on whether staying with Thick Film technology (e.g., FRC0603F6982TS) or upgrading to higher precision Thin Film (e.g., RT0603BRD0780K6L) is more critical, then validate the resistance change.

Main risk

The primary risk is the combination of resistance deviation and, for some candidates, a change from Thick Film to Thin Film technology, which can affect circuit performance.
