Is there a pin-compatible replacement for MOC3061SR2M?

No pin-compatible replacements were identified in this review. Alternatives exist in different packages (like DIP-6) which are not physically compatible without board changes.

What risks should I check before replacing MOC3061SR2M?

Key risks include package mismatch (SMD vs. DIP), ensuring the replacement has a zero-crossing circuit, and verifying the blocking voltage is at least 600V for your application.

MOC3061SR2M Alternatives, Datasheet & Cross Reference | onsemi

MOC3061SR2M is a popular 600V zero-cross triac driver optocoupler from onsemi in a 6-SMD package. Finding a drop-in replacement requires matching the package, pinout, and zero-crossing feature.

AI replacement insight

Package riskhigh

Alternatives are in different packages (DIP) requiring board redesign.

Electrical risklow

Functional matches exist, but must be verified.

Can it be replaced directly?

No direct, drop-in replacement for MOC3061SR2M has been confirmed. Alternatives require careful review of package and pinout.

Best replacement path

Identify a 600V zero-cross triac driver from another manufacturer available in a compatible 6-SMD/SOP Gull Wing package.

Main risk

The primary risk is physical package incompatibility. Many functional alternatives exist in through-hole (DIP) packages, not the target's surface-mount (SMD) package.

Recommended alternatives

The through-hole (DIP) version of the target part family; electrically compatible but not physically.
