Is there a pin-compatible replacement for AC0402FR-07240RL?

While several candidates share the 0402 package, none are a confirmed pin-to-pin replacement due to differences in electrical parameters or qualifications. The closest is AC0402FR-07220RL, which requires review of its resistance value.

What risks should I check before replacing AC0402FR-07240RL?

The main risk is using a non-automotive (non-AEC-Q200) part, which may not withstand the temperature and stress of an automotive environment. Also, check for differences in resistance, tolerance, and technology (thick vs. thin film).

AC0402FR-07240RL Alternatives, Datasheet & Cross Reference | Yageo

AC0402FR-07240RL is a popular 240Ω, 1% tolerance, AEC-Q200 qualified resistor from Yageo. Finding a substitute requires careful matching of its automotive-grade qualification and key electrical parameters.

AI replacement insight

Electrical riskhigh

Using parts with incorrect resistance, tolerance, or technology (thin film) can alter circuit behavior.

Sourcing riskhigh

Substituting a non-AEC-Q200 part into an automotive design violates qualification standards.

Package risklow

All candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, drop-in replacement has been identified. The closest alternative, AC0402FR-07220RL, has a different resistance (220Ω vs 240Ω) and requires engineering review.

Best replacement path

The best replacement path is another AEC-Q200 qualified resistor, such as Yageo's AC0402FR-07220RL, which only differs slightly in resistance.

Main risk

The primary risk is substituting a commercial-grade resistor for this automotive-grade part, which could lead to premature failure in harsh environments.

Recommended alternatives

AEC-Q200 qualified alternative from the same Yageo series with a slightly lower resistance of 220Ω.
