Needs validationlow risk
Pin-compatible upgrade from the same manufacturer with a higher voltage rating.
Best Alternatives to MOCD217M
MOCD217M is a dual-channel phototransistor optocoupler in an 8-SOIC package from onsemi, featuring 2500Vrms isolation and a 30V collector-emitter voltage. It is ideal for high-density applications requiring signal isolation.
AI replacement insight
Electrical risklow
Candidates offer equal or better voltage ratings.
Package risklow
All suggested alternatives use the same 8-SOIC package.
Sourcing risklow
Multiple compatible options exist from onsemi and Vishay.
Can it be replaced directly?
Direct replacement for MOCD217M should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Upgrade within the onsemi MOCD2xx series to MOCD213R2M or MOCD207M for a higher voltage rating.
Main risk
The primary risk is with cross-vendor parts, where subtle differences in dynamic performance (e.g., switching speed) may exist.
