Needs validationlow risk
A potential pin-to-pin replacement with matching resistance and package, but requires review of conflicting power rating data.
Best Alternatives to RTT024023FTH
Find alternatives for the RTT024023FTH, a 402kΩ 1% 0402 resistor. This guide reviews pin-compatible and parametric alternatives from Yageo, FH, and others, focusing on key differences in resistance.
AI replacement insight
Electrical risklow
Resistance value may differ slightly. Power, tolerance, and TCR are generally well-matched.
Package risklow
All suggested alternatives use the same 0402 package, ensuring physical compatibility.
Can it be replaced directly?
Direct replacement for RTT024023FTH should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a near drop-in, consider RC-02K4023FT from FH, which matches all key specs but requires datasheet verification for a power rating data conflict. For a readily available option, RC0402FR-07392KL from Yageo is a close parametric match with a -2.5% resistance difference.
Main risk
The primary risk is minor resistance deviation, as most alternatives are from the E96 series and may not be exactly 402kΩ. This requires circuit tolerance analysis.
