AI replacement insight

Electrical riskmedium

Power rating must be >= 1.5W. Resistance changes require circuit analysis.

Package risklow

All suggested candidates use the same 2512 package.

Can it be replaced directly?

Yes, Yageo RC2512JK-7W200RL is a strong pin-compatible candidate, offering a higher power rating of 2W while matching resistance, tolerance, and package.

Best replacement path

The best path is an upgrade to a higher power rating, like the Yageo RC2512JK-7W200RL (2W), which matches other key specs.

Main risk

The main risk is selecting a part with an insufficient power rating or a resistance value outside the circuit's tolerance.

Recommended alternatives

Pin-compatible upgrade with a 2W power rating, double the target's 1W rating.
