Equivalent & Substitute Parts for UMZ5.6KFHTL Zener Diode Array

Part Overview

UMZ5.6KFHTL from Rohm Semiconductor is an automotive-grade Zener diode array comprising two independent diodes, each rated at 5.61 V nominal Zener voltage, 200 mW power handling, and a reverse leakage current of 1 µA at 2.5 V. It is supplied in a surface-mount SC-82A, SOT-343 (UMD4) package and is AEC-Q101 qualified. The product is currently active and RoHS3 compliant. Identifying alternative models is necessary to provide options for supply continuity or manufacturing flexibility, especially when inventory levels or packaging constraints are a concern.

Key Parameters

Substitute Part Grouping Explanation

For the Zener diode category, substitution is based strictly on electrical characteristics (nominal Zener voltage, tolerance, power rating, reverse leakage current, operating temperature), mechanical parameters (package type, mounting), product grade, and compliance documentation. Only parts matching or closely aligning with these parameters are considered suitable substitutes.

Key parameters used for substitution grouping:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Power - Max
• Current - Reverse Leakage @ Vr
• Operating Temperature
• Grade
• Qualification
• Mounting Type
• Package / Case
• Supplier Device Package
• Product Status
• RoHS Status
• Moisture Sensitivity Level (MSL)
• REACH Status
• ECCN

Parameter Comparison

Engineering Selection Recommendations

Both UMZ5.6KFHTL and EDZVFHT2R5.6B are active components with automotive grade certification and AEC-Q101 qualification. Each is ROHS3 compliant and unaffected by REACH restrictions, with a moisture sensitivity level of 1 (unlimited). Products with matching Zener voltage, tolerance, reverse leakage current, and operating temperature can be considered for direct substitution provided that power rating and package requirements are satisfied according to application needs. Selection should align with compliance standards and product status as indicated.

Frequently Asked Questions (FAQ)

Q1: What are the necessary electrical parameters for substituting UMZ5.6KFHTL in a design?
A1: Substitutes must match the nominal Zener voltage (5.61 V), tolerance, maximum power rating, and reverse leakage current at 2.5 V.

Q2: Does the package type affect substitution eligibility?
A2: Yes. The mounting type, package/case, and supplier device package must be compatible with the design footprint and assembly process.

Q3: Are compliance and qualification parameters important for automotive designs?
A3: Yes, automotive grade and AEC-Q101 qualification are mandatory for automotive applications requiring high reliability.

Q4: Can single-diode arrays replace double-diode configurations?
A4: Only direct electrical, configuration, and packaging equivalence can dictate substitution. Configuration differences must be addressed at the design stage.

Q5: Do both UMZ5.6KFHTL and EDZVFHT2R5.6B have identical compliance statuses?
A5: Both parts are ROHS3 compliant, REACH unaffected, have MSL 1 (unlimited), and are classified as ECCN EAR99.

Q6: What should be considered regarding power rating differences between substitutes?
A6: The substitute's power rating must meet or exceed the requirements of the application or match the main part’s original specification.
