Is there a pin-compatible replacement for MMA02040D1001FB300?

MMA02040C1001FB300 is likely pin-compatible as it is in the same 0204 MELF package family, but its dimensions should be verified against the datasheet before use. No other candidates are pin-compatible.

What risks should I check before replacing MMA02040D1001FB300?

Key risks include package mismatch requiring board changes, insufficient power rating leading to failure, and weaker temperature coefficient (TCR) or different technology (thick film) affecting circuit precision and stability.

MMA02040D1001FB300 Alternatives, Datasheet & Cross Reference | Vishay Beyschlag/Draloric/BC Components

MMA02040D1001FB300 is a precision 1kΩ thin-film MELF resistor from Vishay, rated for 0.4W with a ±25ppm/K TCR. Finding a direct drop-in replacement requires careful matching of its package, power, and precision characteristics.

AI replacement insight

Electrical riskmedium

Weaker TCR in alternatives will impact circuit precision.

Package riskhigh

Most alternatives are not in a MELF package and require board redesign.

Can it be replaced directly?

No direct, fully equivalent replacement was found. The closest option, MMA02040C1001FB300, is a parametric downgrade and requires review.

Best replacement path

Evaluate MMA02040C1001FB300 from the same Vishay series, but you must accept a weaker temperature coefficient (TCR).

Main risk

The primary risks are package incompatibility requiring board redesign and parametric downgrades in temperature stability (TCR).

Recommended alternatives

A close alternative from the same series, but with a weaker temperature coefficient (TCR) and no power margin.
