Is there a pin-compatible replacement for FRL1206FR180TS?

Yes, several parts like HoLRT1206-1W-180mR-1% share the same 1206 package and pinout. However, always verify key electrical parameters like TCR and power rating for your specific application.

What risks should I check before replacing FRL1206FR180TS?

Key risks include differences in Temperature Coefficient of Resistance (TCR), power derating curves, and pulse withstanding capability. A substitute with a high TCR can cause instability in precision circuits.

AI replacement insight

Electrical riskmedium

TCR and technology differences require review.

Package risklow

1206 is a standard package.

Sourcing risklow

Low-ohmic resistors are widely available.

Can it be replaced directly?

While several 1206 180mΩ resistors exist, many have a much worse Temperature Coefficient (TCR). The best path is an upgrade like HoLRT1206-1W-180mR-1%.

Best replacement path

Upgrade to a current-sense resistor like Milliohm's HoLRT1206-1W-180mR-1% for significantly improved power and TCR performance.

Main risk

The main risk is substituting with a part that has a poor Temperature Coefficient (TCR), which can affect circuit accuracy and stability over temperature.

Recommended alternatives

An upgraded alternative in a 1206 package with 4x the power rating and a much better temperature coefficient.
