Is there a pin-compatible replacement for LMJ25NF2P0R006?

Yes, several resistors share the 2512 package and 2-pin layout. MA251230FR006MZ is a form-fit compatible option. However, true pin-to-pin functional compatibility depends on verifying electrical parameters like technology and thermal performance, which may differ.

What risks should I check before replacing LMJ25NF2P0R006?

Key risks include technology differences (e.g., Metal Foil vs. Metal Alloy), which affect long-term stability and thermal EMF. Also, verify the temperature coefficient (TCR) and power derating curves of any alternative to ensure performance and reliability in your circuit.

Electrical riskmedium

Technology and TCR differences require validation.

Package risklow

Candidates share the same 2512 package.

Can it be replaced directly?

No verified direct drop-in replacement is available. MA251230FR006MZ is a strong functional alternative that requires engineering review due to a different resistor technology.

Best replacement path

The best path is to select a candidate with an equal or higher power rating and matching TCR, like MA251230FR006MZ, but validate the impact of its different resistor technology.

Main risk

The primary risk is the difference in resistor technology (Metal Foil vs. Metal Alloy/Substrate), which can impact precision, stability, and thermal characteristics.
