Is there a pin-compatible replacement for HoLRT2512-2W-1R-1%?

While several resistors share the 2512 package, no pin-compatible replacements with identical key electricals (especially TCR) were found. Any alternative requires careful datasheet comparison.

What risks should I check before replacing HoLRT2512-2W-1R-1%?

The main risk is performance degradation. Check the Temperature Coefficient (TCR), resistance tolerance, and technology (e.g., Thin vs. Thick Film). A higher TCR can cause resistance to drift with temperature, affecting circuit accuracy.

Finding a substitute for the HoLRT2512-2W-1R-1% 1Ω 1% 2W resistor requires careful attention to its low TCR of ±50ppm/°C. Alternatives exist but may require trade-offs in temperature stability or precision.

AI replacement insight

Electrical riskhigh

TCR and tolerance mismatches can significantly impact circuit accuracy and stability.

Package risklow

Candidates share the same 2512 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, drop-in replacement with identical performance was found. All candidates require a review of parametric trade-offs.

Best replacement path

Parametric relaxation. Accept a substitute with a weaker TCR, like Yageo's RC2512FK-7W1RL, after verifying its impact on circuit performance.

Main risk

The primary risk is a loss of precision due to a higher Temperature Coefficient of Resistance (TCR) or wider tolerance.

Recommended alternatives

A 1Ω, 1%, 2W resistor in a 2512 package with a higher temperature coefficient (TCR).
