Resistance deviation in some candidates requires circuit analysis.

Package riskhigh

Some alternatives have different footprints requiring board changes.

Can it be replaced directly?

No direct drop-in replacement was found that meets the strict 1.5x power safety margin. The closest options require reviewing parametric or package differences.

Best replacement path

RC1206FR-7W470RL offers a similar form factor with a higher power rating, but its resistance is 9% higher. For new designs, 0402WGF4300TCE is an option if a smaller package is acceptable.

Main risk

The main risks are package incompatibility and resistance deviation. No direct replacement meets all criteria including a 1.5x power margin.

Recommended alternatives

A 1206 resistor with a higher power rating but slightly different resistance (470Ω vs 430Ω).
