Parametrically similar but lacks the target's AEC-Q200 automotive qualification.
Best Alternatives to AC0402FR-0733KL
AC0402FR-0733KL is a 33kΩ, 1% tolerance, 1/16W thick film chip resistor in a 0402 package, qualified to AEC-Q200 for automotive applications. Finding a direct, qualified replacement requires careful verification.
AI replacement insight
Electrical riskhigh
Using a non-AEC-Q200 part in an automotive design can lead to reliability issues and system failure.
Package risklow
Most candidates match the 0402 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, AEC-Q200 qualified replacement has been identified. All reviewed options are commercial grade and represent a downgrade in qualification.
Best replacement path
For non-automotive use, WR04X3302FTL offers matching electricals. For automotive use, a new search for AEC-Q200 qualified 33kΩ 1% 0402 resistors is required.
Main risk
The primary risk is substituting a commercial-grade resistor for an automotive-grade (AEC-Q200) component, which may lead to premature failure in harsh environments.
