A 1206 resistor with same resistance and power, but a wider ±5% tolerance.
Yageo's RL1206FR-070R5L is a popular AEC-Q200 qualified 0.5Ω, 1% tolerance, 0.25W chip resistor in a 1206 package, commonly used for current sensing in automotive and industrial applications. Finding a direct replacement requires careful parametric evaluation.
Resistance values differ by 2-6%, and one candidate has a much wider tolerance (5% vs 1%).
All candidates share the same 1206 package, ensuring form-fit compatibility.
Several candidates are not AEC-Q200 qualified, which is a requirement for automotive applications where the target is often used.
No direct drop-in replacement was found. All suitable alternatives have parametric differences in resistance or tolerance that require engineering review.
Use a part from the same Yageo RL series, such as RL1206FR-070R47L, if a -6% resistance deviation is acceptable for the application.
The primary risk is a change in resistance value, which can affect circuit performance, especially in current sensing applications.

The best alternatives are likely from the same Yageo RL series. RL1206FR-070R47L is a strong choice if a 0.47Ω resistance is acceptable. For a power upgrade, consider RL1206FR-7W0R47L. Both require review due to the resistance difference.
