An excellent alternative from the same manufacturer series with a minor resistance difference.
FRC0603F6652TS is a general-purpose 66.5kΩ 1% 0.1W thick film resistor in a standard 0603 package. Several strong, pin-compatible alternatives from manufacturers like Yageo and FOJAN are available, typically requiring only validation of a minor resistance difference.
Minor resistance change is the main factor. Power, voltage, and TCR are well-matched by top candidates.
All top candidates use the same standard 0603 package, ensuring form and fit compatibility.
Direct replacement for FRC0603F6652TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path is to select a thick film 0603 resistor with a resistance value as close to 66.5kΩ as possible, such as 68kΩ or 68.1kΩ, while matching the 0.1W power rating and 1% tolerance.
The primary risk is the slight change in resistance value, which could affect the behavior of precision analog circuits like voltage dividers, filters, or feedback networks.
