Needs validationlow risk
An automotive-grade upgrade from the same manufacturer with a higher voltage rating and identical package.
Best Alternatives to MRA4004T3G
Finding a replacement for the MRA4004T3G standard recovery diode involves matching the SMA package, 1A current, and 400V or higher voltage rating. Key alternatives include direct upgrades with higher ratings and automotive-grade options.
AI replacement insight
Package risklow
The SMA (DO-214AC) package is standard and widely available.
Electrical riskmedium
Risk is low if matching diode type (standard recovery), but medium if using a fast recovery diode.
Sourcing risklow
Many manufacturers produce suitable alternatives for this common diode type.
Can it be replaced directly?
Direct replacement for MRA4004T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
S2MA as a direct, higher-spec replacement or NRVA4007T3G as a high-reliability upgrade from the original manufacturer.
Main risk
The primary risk is substituting a standard recovery diode with a fast or ultrafast one, which can affect circuit performance, especially in switching applications.
