Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based on strict adherence to the key electrical and mechanical parameters required for the Zener diode product category. These parameters include Zener voltage (Vz), tolerance, maximum power dissipation, Zener impedance (Zzt), maximum reverse leakage current, forward voltage, operating temperature range, mounting type, package, and compliance status. Only parts matching these criteria exactly and belonging to the same manufacturer and package category are considered parametric equivalents or substitutes.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and adhere to ROHS3 and REACH compliance. The MMSZ5246BQ-13-F and MMSZ5246BQ-7-F substitutes are additionally qualified to AEC-Q101 and designated as automotive grade, potentially expanding their suitability for automotive environments under existing application requirements. Selection may be driven by inventory levels, qualification status, and specific packaging needs where all key parametric criteria are satisfied.

Frequently Asked Questions (FAQ)

Q1: What are the substitution criteria for Zener diodes in the SOD-123 package?
A1: Substitution strictly requires matching Zener voltage, tolerance, power rating, impedance, reverse leakage current, forward voltage, operating temperature range, mounting type, and package. Compliance with ROHS3 and REACH may also be necessary.

Q2: Do automotive grade or AEC-Q101 qualified substitutes differ in electrical performance?
A2: For these parts, all electrical parameters are identical. The distinction lies in qualification and intended use case certifications.

Q3: Is there a mechanical difference between MMSZ5246B-13-F and its substitutes?
A3: No, all specified parts share the SOD-123 package and surface mount configuration, ensuring mechanical compatibility.

Q4: How should packaging suffixes (e.g., -13-F, -7-F) be considered when choosing a substitute?
A4: Suffixes indicate tape & reel quantity and configuration. Selection should match production requirements but does not affect part electrical or mechanical equivalency.

Q5: Are all substitutes in current active production and compliant with environmental regulations?
A5: Yes, all listed substitutes are active, ROHS3 compliant, and REACH unaffected based on provided status.
