Is there a pin-compatible replacement for HoLLR1206-1W-70mR-1%?

Yes, several pin-compatible alternatives in a 1206 package exist, such as YLRY06-1-65F. However, they have slightly different resistance values (e.g., 65mΩ vs 70mΩ), so they are not drop-in replacements and require engineering review.

What risks should I check before replacing HoLLR1206-1W-70mR-1%?

Key risks include resistance deviation affecting current measurement accuracy, a narrower operating temperature range impacting reliability in harsh environments, and different resistor technology which can alter performance.

AI replacement insight

Electrical riskmedium

Resistance deviation affects current measurement accuracy and may require circuit adjustments.

Package risklow

All viable candidates are 1206 package, ensuring form-fit compatibility.

Sourcing risklow

Multiple vendors offer similar current sense resistors in this range.

Can it be replaced directly?

No direct drop-in replacement has been identified; all viable candidates have parametric differences, primarily in resistance value, that require engineering review.

Best replacement path

Parametric alternatives with slightly different resistance values (65mΩ-75mΩ) are available.

Main risk

The primary risk is the change in resistance value, which will directly impact the accuracy of the current sensing circuit.

Recommended alternatives

A 1206 1W resistor with slightly lower resistance (65mΩ) but better temperature stability (TCR ±50ppm/°C).
