Needs validationhigh risk
Functionally equivalent but in an SMD package, requiring a different board layout.
Best Alternatives to MOC3052M
MOC3052M is a popular 600V random-phase triac driver optocoupler from onsemi in a 6-pin DIP package. Finding a substitute requires matching the package, off-state voltage, and random-phase control feature.
AI replacement insight
Package riskhigh
Choosing an SMD part like MOC3052SR2M requires a board redesign.
Electrical riskmedium
Using a part with different trigger current (IFT) may require circuit adjustments.
Can it be replaced directly?
Direct replacement for MOC3052M should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a drop-in replacement, consider Vishay's VO3052. For new designs using surface-mount, onsemi's MOC3052SR2M is the same part in an SMD package.
Main risk
The main risk is selecting a part with a different package (SMD vs. DIP) or a lower blocking voltage (VDRM < 600V).
