Yageo
Automotive-grade alternative with matching package, tolerance, and TCR, but slightly lower resistance (499Ω).
ERA2AEB511X is a high-precision, automotive-grade (AEC-Q200) 510Ω thin film resistor in a 0402 package. Finding a direct drop-in requires matching its tight tolerance, low TCR, and automotive qualification.
Resistance value changes require circuit validation.
Many 0402 package resistors are available.
AEC-Q200 parts may have different supply constraints than commercial grade.
No exact drop-in replacement is identified. The closest options require accepting a small change in resistance or forgoing the AEC-Q200 qualification.
The best path is finding an AEC-Q200 qualified thin film resistor with a close resistance value, like Yageo's AT0402BRD07499RL (499Ω).
The main risk is performance degradation from using a part with different resistance, wider tolerance, higher TCR, or lack of automotive qualification.

| Feature / factor | ERA2AEB511X | AT0402BRD07499RL | RT0402BRD07510RL | ERA2AEB471X | Compatibility / risk |
|---|---|---|---|---|---|
| Resistance | 510 Ω | 499 Ω | 510 Ω | 470 Ω | 499 Ω / 510 Ω / 470 Ω — 2.1% lower than target. Verify circuit sensitivity.; RT0402BRD07510RL: matched; ERA2AEB471X: 7.8% lower than target. Verify circuit tolerance. |
| Application | AEC-Q200 | AEC-Q200 | Commercial | AEC-Q200 | AEC-Q200 / Commercial — Matches automotive qualification.; RT0402BRD07510RL: Candidate is not AEC-Q200 qualified.; ERA2AEB471X: From same automotive series. |
| Tolerance | ±0.1% | ±0.1% | ±0.1% | ±0.1% | ±0.1% — matched; RT0402BRD07510RL: matched; ERA2AEB471X: matched |
| Tcr | ±25 ppm/°C | ±25 ppm/°C | 25 ppm/°C | ±25 ppm/°C | ±25 ppm/°C — matched; RT0402BRD07510RL: matched; ERA2AEB471X: matched |
| Power | 0.063W | 0.0625W | - | - | 0.0625W — Effectively same power rating. |
Yageo's AT0402BRD07499RL is a strong alternative if a 2% resistance change (499Ω vs 510Ω) is acceptable, as it matches the AEC-Q200 rating and other key specs.
