Key Parameters

Substitute Part Grouping Explanation

Substitute eligibility for Zener diodes in this category is determined strictly by direct equivalence in several key parameters: nominal Zener voltage, voltage tolerance, maximum power dissipation, Zener impedance, reverse leakage current, operating temperature, automotive grade and qualification, mounting method, and package compatibility. The substitute must match or specify all compliance and regulatory statuses, such as RoHS3, REACH, AEC-Q101, ECCN, and MSL, with identical or equivalent package outlines.

Parameter Comparison

Engineering Selection Recommendations

For all substitute selections, product status must be active, and each candidate must conform to automotive AEC-Q101 standards, ROHS3 compliance, REACH requirements, ECCN: EAR99, and moisture sensitivity level ratings as specified. Package compatibility and mounting type must match to ensure mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: What determines if a Zener diode can be substituted in this category?
A: Substitution is determined by direct equivalence in Zener voltage, tolerance, maximum power, impedance, reverse leakage current, operating temperature, grade, regulatory qualification, mounting type, and package similarity.

Q: Are all packages within TO-236-3, SC-59, and SOT-23-3 interchangeable?
A: Package / case designations TO-236-3, SC-59, and SOT-23-3 are explicitly listed as compatible for substitution in this context.

Q: What compliance standards are required for automotive Zener diode substitution?
A: Substitute parts must be AEC-Q101 qualified, ROHS3 compliant, REACH unaffected, and meet the specified ECCN and MSL levels.

Q: Can there be differences in nominal Zener voltage?
A: Substitute parts listed must have comparable specified nominal Zener voltage values and tolerances within the parameters provided.

Q: Must the supplier device package naming match exactly?
A: Either SSD3 or SOT-23, as listed, are within the allowed package outlines for substitution.
