UNI-ROYAL
Matches resistance and package but has a lower power rating and is not AEC-Q200 qualified. Engineering review is required.
Finding a substitute for the Panasonic ERJ2RKF3243X 324kΩ resistor requires careful review of its 0.1W power rating and AEC-Q200 qualification. While some parts match the 0402 package, key electrical parameters differ.
All candidates have a lower power rating, posing a reliability risk.
All candidates match the 0402 package.
Lack of AEC-Q200 qualification makes candidates unsuitable for automotive applications.
No direct drop-in replacement was found. All candidates have a lower power rating (0.0625W vs 0.1W) and are not specified as AEC-Q200.
The UNI-ROYAL 0402WGF3243TCE matches resistance but has a lower power rating and lacks AEC-Q200 qualification, making it a high-risk downgrade.
The primary risk is the lower power rating of all candidates, which could lead to component failure if the circuit dissipates more than 0.0625W.

| Feature / factor | ERJ2RKF3243X | 0402WGF3243TCE | FRC0402F3303TS | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0402 | 0402 | 0402 | 0402 — Package size matches.; FRC0402F3303TS: Package size matches. | |
| Resistance | 324kΩ | 324kΩ | 330kΩ | 324kΩ / 330kΩ — Resistance value matches.; FRC0402F3303TS: Resistance differs by +1.85%, which may be acceptable. | |
| Power | 0.1W | 0.0625W | 0.0625W | 0.0625W — Power rating is a significant downgrade.; FRC0402F3303TS: Power rating is a significant downgrade. | |
| Tcr | ±100 ppm/°C | Not Specified | ±100 ppm/°C | Not Specified / ±100 ppm/°C — TCR is a key parameter for precision and is missing.; FRC0402F3303TS: Temperature coefficient matches. | |
| Application | AEC-Q200 | No | No | No — Candidate is not AEC-Q200 qualified.; FRC0402F3303TS: Candidate is not AEC-Q200 qualified. |
The closest option is 0402WGF3243TCE, which matches the 324kΩ resistance but has a lower 0.0625W power rating and is not AEC-Q200 qualified. This is a high-risk substitute requiring circuit analysis.
