Best Alternatives to MOC3061M

Package: 6-DIP (0.300", 7.62mm)onsemiSCR OutputPackage: TubeProduct Status: ActiveNumber of Channels: 1Voltage - Isolation: 4170VrmsVoltage - Off State: 600 V

The onsemi MOC3061M is a 600V zero-crossing triac driver in a 6-DIP package. While no exact 1-to-1 replacement exists, several functional and pin-compatible alternatives are available, requiring careful review of isolation voltage and package type.

AI replacement insight

Electrical riskmedium

Most alternatives have a lower isolation voltage (5kV or less vs 7.5kV), which must be verified against system safety requirements.

Package riskhigh

Some alternatives like MOC3061SR2M are in SMD packages and require a complete PCB layout change.

Sourcing risklow

Alternatives exist from multiple vendors, but qualification is needed for cross-vendor parts.

Can it be replaced directly?

Direct replacement for MOC3061M should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

OR-MOC3062 is the most promising path for a near drop-in replacement, provided its lower 5000Vrms isolation voltage is acceptable for the application.

Main risk

The primary risk across all viable alternatives is a lower isolation voltage rating compared to the onsemi MOC3061M's 7500V.
