RT0402BRD0747KL
Yageo
Needs validationmedium risk
A parametric alternative with matched precision but different resistance (47kΩ) and no automotive qualification.
Best Alternatives to AT0402BRD0745K3L
The Yageo AT0402BRD0745K3L is a precision, AEC-Q200 qualified 45.3kΩ thin film resistor in an 0402 package, ideal for automotive and high-stability applications. Finding a direct replacement is challenging due to its specific parameters.
AI replacement insight
Electrical riskhigh
Candidates may have different resistance, tolerance, or TCR.
Package risklow
All reviewed candidates use the same 0402 package.
Sourcing riskhigh
Lack of AEC-Q200 qualification makes candidates unsuitable for automotive applications.
Can it be replaced directly?
No direct, pin-compatible AEC-Q200 replacement with the exact 45.3kΩ resistance was found. Alternatives require careful review of parametric differences.
Best replacement path
For non-automotive applications, Yageo's RT series offers similar precision but requires checking resistance value differences.
Main risk
The primary risks are the lack of AEC-Q200 qualification in alternatives and deviations in resistance value or precision (tolerance and TCR).

Questions & answers
For high-precision needs, parts like Yageo's RT0402BRD0747KL are close but have a different resistance (47kΩ) and lack AEC-Q200. For cost-sensitive, less precise applications, thick film resistors like FH's RC-02K4532FT match the resistance value but have lower precision.
