AI replacement insight

Electrical risklow

Upgrades have better or equal electrical specifications.

Package risklow

All recommended parts are in the same 1206 package.

Sourcing riskmedium

Target and candidates are from less common manufacturers; check distributor stock.

Can it be replaced directly?

No direct 1W replacements meet the required 1.5x power safety margin. The best path is to use a 2W or 3W rated part like HoSRX1206-2W-1mR-1%, which is an upgrade.

Best replacement path

Upgrade to a higher power rated part like HoSRX1206-2W-1mR-1% for increased robustness and better TCR.

Main risk

The primary consideration is thermal management, as the upgrades have higher power ratings (2W/3W vs 1W).

Recommended alternatives

A 1206 1mΩ resistor with higher 2W power rating and better ±50ppm/°C TCR, offering a robust upgrade.
