AI replacement insight
Application riskhigh
Lack of AEC-Q200 qualification on all candidates is a major risk for automotive or high-reliability applications.
Electrical risklow
Minor power rating differences exist. Some candidates have wider tolerance, which is a downgrade risk.
Can it be replaced directly?
No direct drop-in replacement has been identified that matches all key parameters, including AEC-Q200 qualification. All candidates require engineering review.
Best replacement path
For precision, RT0402BRD0733RL offers upgraded tolerance/TCR. For general use, WR04X33R0FTL is a close match. Both require checking AEC-Q200 needs.
Main risk
The primary risk is the lack of AEC-Q200 qualification in all reviewed candidates, making them unsuitable for automotive applications without requalification.
