Electrical riskmedium
Substitutes may have different resistance, TCR, or technology.
Package risklow
All suggested alternatives are in the same 0603 package.
Sourcing risklow
This is a common resistor value with multiple vendors.
Can it be replaced directly?
Direct replacement for FRC0603F3403TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a direct replacement, find a 340kΩ, 1%, 0.1W, 0603 thick film resistor like 0603WAF3403T5E. For higher precision, consider a thin film upgrade like RT0603BRD07340KL.
Main risk
The main risk is using a part with a different resistance value or technology (thin film) without verifying its impact on circuit performance.
