A strong parametric match in a 1206 package, but lacks the target's AEC-Q200 automotive qualification.
Finding a substitute for the Yageo AC1206FR-073K3L, an AEC-Q200 qualified 3.3kΩ 1% 1206 resistor, requires careful review. Key considerations are matching the automotive qualification and electrical parameters.
Using a non-AEC part in an automotive design poses a high reliability risk.
Several candidates match the 1206 package, ensuring physical compatibility.
No, a direct, fully-qualified drop-in replacement for AC1206FR-073K3L was not identified. All candidates lack the AEC-Q200 automotive qualification.
No direct AEC-Q200 drop-in replacement was found. The best path is to evaluate general-purpose resistors like FRC1206F3301TS for non-automotive use, verifying all parameters.
The primary risk is using a non-automotive grade component in an application requiring AEC-Q200 reliability standards.

| Feature / factor | AC1206FR-073K3L | FRC1206F3301TS | RC1206JR-073K3L | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1206 | 1206 | 1206 | 1206 — Package size matches.; RC1206JR-073K3L: Package size matches. | |
| Resistance | 3.3 kΩ | 3.3 kΩ | - | 3.3 kΩ — Resistance value matches. | |
| Tolerance | ±1% | ±1% | ±5% | ±1% / ±5% — Tolerance matches.; RC1206JR-073K3L: Wider tolerance may affect circuit precision. | |
| Power | 0.25 W | 0.25 W | - | 0.25 W — Power rating matches but lacks engineering safety margin. | |
| Application | AEC-Q200 | Not specified | Not specified | Not specified — Candidate is not AEC-Q200 qualified.; RC1206JR-073K3L: Candidate is general purpose, not AEC-Q200 qualified. | |
| Tcr | ±100 ppm/°C | - | ±200 ppm/°C | ±200 ppm/°C — Higher temperature coefficient indicates less stability. |
For non-automotive applications, FRC1206F3301TS is a strong parametric match. However, it lacks AEC-Q200 qualification, which must be acceptable for your design.
