Yageo RC2512FK-7W1RL is a pin-compatible upgrade with 2W power rating and improved TCR.
Find reliable substitutes for the RC-12L1R00FT, a 1W, 1Ω, 1% resistor in a 2512 package. This page provides verified pin-compatible alternatives and parametric options to meet your design and sourcing needs.
Key parameters like resistance and tolerance are matched or improved in top candidates. Power rating is upgraded.
All viable candidates use the same 2512 package, ensuring physical compatibility.
Candidates from major manufacturers like Yageo offer broad availability.
Direct replacement for RC-12L1R00FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path is RC2512FK-7W1RL by Yageo. It matches the package, resistance, tolerance, and technology while offering a higher 2W power rating and better TCR for increased reliability.
The main risk when substituting is ensuring the replacement's characteristics, such as tolerance and pulse handling capability (related to film technology), meet the specific application's requirements.

| Feature / factor | RC-12L1R00FT | RC2512FK-7W1RL | HoLRT2512-2W-1R-1% | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 2512 | 2512 | 2512 | 2512 — Same EIA package ensures form-fit compatibility.; HoLRT2512-2W-1R-1%: Same EIA package ensures form-fit compatibility. | |
| Resistance | 1.0Ω | 1.0Ω | 1.0Ω | 1.0Ω — Resistance value is identical.; HoLRT2512-2W-1R-1%: Resistance value is identical. | |
| Power | 1.0W | 2.0W | 2.0W | 2.0W — Higher power rating provides greater design margin.; HoLRT2512-2W-1R-1%: Higher power rating provides greater design margin. | |
| Tolerance | ±1.0% | ±1.0% | - | ±1.0% — Resistance tolerance is identical. | |
| Tcr | ±250ppm/℃ | ±200ppm/°C | ±50ppm/℃ | ±200ppm/°C / ±50ppm/℃ — Lower TCR provides better stability over temperature.; HoLRT2512-2W-1R-1%: Significantly lower TCR improves stability. | |
| Technology | Thick Film | Thick Film | Alloy Thin-Film | Thick Film / Alloy Thin-Film — Matching technology suggests similar pulse handling.; HoLRT2512-2W-1R-1%: Different technology may affect pulse/surge behavior. |
Verified drop-in options for RC-12L1R00FT are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
