The 1N4007 is a widely used 1A, 1000V general-purpose rectifier. This page details verified alternatives, including pin-compatible upgrades and functional alternates in different packages for the SMA variant.

AI replacement insight

Package riskhigh

Many package variants use the 1N4007 name. SMA, DO-41, and SOD-123 are common but not interchangeable.

Electrical risklow

The 1A, 1000V rating is a well-defined standard.

Sourcing risklow

Extremely common part with many manufacturers and high availability.

Can it be replaced directly?

Yes, the M7 is a direct, pin-compatible replacement for the SMA-packaged 1N4007.

Best replacement path

For a drop-in replacement, use M7. For an upgrade in the same footprint, use S2M.

Main risk

The primary risk is selecting a part with the same '1N4007' number but in a different package (e.g., through-hole DO-41 or smaller SOD-123FL). Always verify the package code.

Questions & answers

The M7 diode is widely considered the direct SMD equivalent to the through-hole 1N4007 and is a strong pin-compatible match for other SMA-packaged 1N4007 variants. For higher current needs in the same package, the S2M is an excellent upgrade.
