AI replacement insight

Electrical risklow

Key parameters like resistance and tolerance are easy to match. Focus on power rating and TCR.

Package risklow

The 2512 package is a standard size, ensuring physical compatibility.

Sourcing riskmedium

While the target is from a major brand, some alternatives may have different supply chain availability.

Can it be replaced directly?

Yes, several parts are available. The Yageo RC2512JK-7W100RL is a direct upgrade path with a higher power rating. Cross-vendor options like UNI-ROYAL's AS122WJ0101T4E also exist but require TCR verification.

Best replacement path

Upgrade to a higher power rating like the 2W RC2512JK-7W100RL from the same manufacturer for increased design margin.

Main risk

The main risk is using a replacement with insufficient power or voltage rating, or a different temperature coefficient (TCR) that could affect circuit stability.

Recommended alternatives

A 2W power upgrade from the same Yageo series in an identical 2512 package.
