Parametrically similar 249Ω 1% 0.25W resistor in a 1206 package, but lacks automotive AEC-Q200 qualification.
Finding a substitute for the Yageo AC1206FR-07249RL, a 249Ω 1% 0.25W 1206 resistor, requires careful attention to its AEC-Q200 qualification for automotive use. While parametric matches exist, they may not meet the same reliability standards.
Lack of AEC-Q200 qualification makes candidates unsuitable for automotive use without extensive testing.
All candidates share the same 1206 package, ensuring physical compatibility.
No, there are no direct drop-in replacements in this list because none of the candidates are AEC-Q200 qualified like the target part.
For non-automotive applications, FRC1206F2490TS is a strong parametric match. For automotive use, a different AEC-Q200 qualified part is required.
The primary risk is using a non-automotive qualified component in an application that requires AEC-Q200 reliability standards.
