FOJAN
This FOJAN resistor is a strong match with identical resistance, tolerance, power, TCR, and package.
Finding a substitute for the RC-02K4532FT 45.3kΩ resistor involves matching its 0402 package, 1% tolerance, and thick film technology. Several alternatives exist, from direct pin-compatible matches to parametric alternatives requiring review.
All candidates share the same 0402 package, ensuring physical compatibility.
Some candidates have different resistance values or technology, which requires circuit analysis before substitution.
Direct replacement for RC-02K4532FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for RC-02K4532FT, then review parametric alternatives for package and electrical fit.
The main risk is using a part with a different resistance value or technology (Thin Film vs. Thick Film) without evaluating the impact on circuit performance.
