FOJAN
Functionally similar with same resistance and tolerance, but lacks automotive qualification.
Finding a substitute for the Yageo AC0402FR-0713KL involves matching its 13kΩ resistance, 1% tolerance, and critical AEC-Q200 automotive qualification in a 0402 package.
Using a non-automotive part in an automotive system is a critical risk.
Several candidates have resistance values that deviate from the target.
All candidates share the same 0402 package, ensuring physical compatibility.
No direct, drop-in replacement has been identified. All candidates have parametric or qualification differences requiring engineering review.
For automotive use, AC0402FR-0712KL is a strong choice if the circuit tolerates 12kΩ. For non-automotive use, FRC0402F1302TS is a functional match.
The primary risk is substituting a non-AEC-Q200 qualified part into an automotive application, which can compromise reliability and safety.

| Feature / factor | AC0402FR-0713KL | FRC0402F1302TS | AC0402FR-0712KL | RT0402BRD0713KL | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0402 | 0402 | - | - | 0402 — Form factor matches. |
| Resistance | 13kΩ | 13kΩ | 12kΩ | - | 13kΩ / 12kΩ / 12.4kΩ — Resistance value matches.; AC0402FR-0712KL: Resistance differs by -7.7%.; FRC0402F1242TS: Resistance differs by -4.6%. |
| Tolerance | ±1% | ±1% | - | ±0.1% | ±1% / ±0.1% — Tolerance matches.; RT0402BRD0713KL: Tighter tolerance is an upgrade. |
| Application | AEC-Q200 | None | AEC-Q200 | None | None / AEC-Q200 — Candidate is general purpose, target is automotive grade.; AC0402FR-0712KL: Both are AEC-Q200 qualified.; RT0402BRD0713KL: Lacks AEC-Q200 automotive qualification.; FRC0402F1242TS: Candidate is general purpose, not automotive. |
| Technology | Thick Film | - | - | Thin Film | Thin Film — Candidate is Thin Film, offering higher precision. |
| Tcr | ±100 ppm/°C | - | - | 25 ppm/°C | 25 ppm/°C — Lower TCR provides better stability. |
For automotive uses, AC0402FR-0712KL is a strong candidate if a 12kΩ resistance is acceptable. For general-purpose applications, FRC0402F1302TS offers the same electrical parameters but lacks AEC-Q200 qualification.
