Substitute Categories:

Direct Equivalents match all primary criteria without functional or mechanical deviation. These parts are pin-compatible and electrically interchangeable.

Upgrade Substitutes exceed the original specifications in power rating or include additional certifications (such as AEC-Q200 automotive qualification) while maintaining all other parameters. These parts are functionally superior and backward-compatible.

Similar Substitutes match all electrical and mechanical parameters but include enhanced features (automotive qualification, anti-sulfur treatment, or moisture resistance enhancements) or minor dimensional variations within tolerance. These parts are compatible for applications requiring additional environmental protection.
