Yageo
A close parametric match from the same series, but with a 33kΩ resistance instead of 30kΩ.
The Yageo RT0603BRD0730KL is a precision 30 kΩ thin-film chip resistor in a 0603 package, featuring ±0.1% tolerance and a 25 ppm/°C TCR. Finding a direct replacement requires matching these tight specifications.
High risk if using a thick-film part or one with different resistance in a precision application.
Low risk as all viable candidates share the same 0603 package.
No direct, drop-in replacement with identical key parameters has been identified among the candidates. All proposed alternatives require engineering review.
The closest option is RT0603BRD0733KL, which has a 10% higher resistance. If the circuit cannot tolerate this, a new search for a 30kΩ, 0.1%, 25ppm/°C thin-film resistor is required.
The main risk is performance degradation due to mismatched precision parameters (tolerance, TCR) or a shift in resistance value.

| Feature / factor | RT0603BRD0730KL | RT0603BRD0733KL | RC0603FR-0730KL | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 | 0603 | 0603 | 0603 — Package size matches.; RC0603FR-0730KL: Package size matches. | |
| Resistance | 30kΩ | 33kΩ | 30kΩ | 33kΩ / 30kΩ — Resistance is 10% higher than target.; RC0603FR-0730KL: Resistance value matches. | |
| Tolerance | ±0.1% | ±0.1% | ±1% | ±0.1% / ±1% — Precision tolerance matches.; RC0603FR-0730KL: Tolerance is 10x wider, a significant precision downgrade. | |
| Tcr | 25 ppm/°C | 25 ppm/°C | ±100 ppm/°C | 25 ppm/°C / ±100 ppm/°C — Temperature coefficient matches.; RC0603FR-0730KL: TCR is 4x higher, indicating lower stability over temperature. | |
| Technology | Thin Film | Thin Film | Thick Film | Thin Film / Thick Film — Technology matches.; RC0603FR-0730KL: General purpose thick film vs precision thin film. |
The best alternative depends on circuit tolerance. Yageo's RT0603BRD0733KL is a close match with 33kΩ resistance. For general use, RC0603FR-0730KL has the same resistance but is a lower-precision thick-film part.
