FOJAN
A 3.3Ω 1% 0402 resistor with a higher TCR; review temperature stability for your application.
The Yageo RC0402FR-073R3L is a common 3.3 Ohm, 1% tolerance, 0402 chip resistor. While direct drop-in replacements are available, several functional alternatives with minor parametric differences require engineering review.
Candidates may have different resistance values or weaker TCR, impacting circuit precision and stability.
All reviewed candidates use the same 0402 package, ensuring physical compatibility.
This is a common resistor value and package, with many alternative manufacturers available.
No datasheet-verified, drop-in replacement has been confirmed. However, parts like FOJAN's FRC0402F3R30TS match key parameters but have a weaker Temperature Coefficient (TCR), requiring review.
The best replacement path is to find a 3.3Ω, ±1%, 0.0625W (or higher), 0402 resistor with a TCR of ±200 ppm/°C or better. Several manufacturers offer parts with these specifications.
The main risk when substituting is accepting a part with a different resistance value, a wider tolerance (e.g., ±5%), or a higher TCR, which can affect circuit performance and stability.

|---|---|---|---|---|---|
| Package | 0402 | 0402 | 0402 | 0402 | 0402 — Same package and pin count.; FRC0402F3R00TS: Same package and pin count.; RC-02U3R00FT: Same package and pin count.; 0402WGJ033JTCE: Same package and pin count. |
| Resistance | 3.3Ω | 3.3Ω | 3.0Ω | 3.0Ω | 3.3Ω / 3.0Ω — matched; FRC0402F3R00TS: Resistance value is ~9% lower.; RC-02U3R00FT: Resistance value is ~9% lower.; 0402WGJ033JTCE: matched |
| Tolerance | ±1% | ±1% | ±1% | ±1% | ±1% / ±5% — matched; FRC0402F3R00TS: matched; RC-02U3R00FT: matched; 0402WGJ033JTCE: Significantly wider tolerance. |
| Tcr | ±200 ppm/°C | ±400 ppm/°C | ±400 ppm/°C | ±400 ppm/°C | ±400 ppm/°C / Not specified — Candidate TCR is higher, less stable with temperature.; FRC0402F3R00TS: Candidate TCR is higher, less stable with temperature.; RC-02U3R00FT: Candidate TCR is higher, less stable with temperature.; 0402WGJ033JTCE: TCR data is missing from available sources. |
| Power | 0.0625W | 0.0625W | - | - | 0.0625W — Power rating matches but lacks recommended 1.5x safety margin. |
The best alternative would be a resistor with identical or better specifications: 3.3Ω, ±1% tolerance, 0.0625W or higher power, 0402 package, and TCR of ±200ppm/°C or lower. Always verify datasheets for full compatibility.
