DZ4J030K0R Equivalent & Substitute Parts

Part Overview

The DZ4J030K0R is a Zener Diode Array manufactured by Panasonic Electronic Components, configured as 2 independent 3 V Zener diodes in a SMini4-F3-B surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The 200 mW power rating and 3 V nominal Zener voltage establish the functional requirements for equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ4J030K0R is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Configuration: 2 Independent Zener diodes
• Voltage - Zener (Nom): 3 V
• Power - Max: 200 mW
• Current - Reverse Leakage @ Vr: 50 µA @ 1 V
• Voltage - Forward (Vf) (Max) @ If: Maximum 1 V @ 10 mA

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

The MMBZ5225BS-7-F meets all electrical equivalence criteria and maintains surface mount compatibility. While the package form differs (SOT-363 versus SMini4-F3-B), both are surface mount configurations suitable for PCB integration with appropriate footprint redesign.

Parameter Comparison

Engineering Selection Recommendations

The MMBZ5225BS-7-F is the qualified substitute for the DZ4J030K0R based on the following factors:

Electrical Performance: The substitute maintains identical Zener voltage (3 V), power rating (200 mW), and reverse leakage current (50 µA @ 1 V). The forward voltage specification of the MMBZ5225BS-7-F (900 mV @ 10 mA) is superior to the original part (1 V @ 10 mA), providing improved performance characteristics.

Product Status: The MMBZ5225BS-7-F is classified as Active, ensuring long-term availability and supply chain continuity. The original DZ4J030K0R is obsolete, necessitating transition to an active equivalent.

Compliance & Certifications: The MMBZ5225BS-7-F carries RoHS3 Compliance and REACH Unaffected status, meeting current regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications.

Package Consideration: PCB layout modification is required due to package transition from SMini4-F3-B (4-SMD, Flat Leads) to SOT-363 (6-TSSOP, SC-88). The substitute provides improved impedance characteristics (30 Ohms versus 120 Ohms), which may enhance circuit performance in voltage regulation applications.

Frequently Asked Questions (FAQ)

Q: Can the MMBZ5225BS-7-F directly replace the DZ4J030K0R without circuit modification?

A: Electrical substitution is valid. However, package geometry differs between SMini4-F3-B and SOT-363, requiring PCB footprint redesign. Functional performance is maintained across all critical electrical parameters.

Q: What is the significance of the impedance difference (120 Ohms vs. 30 Ohms)?

A: Lower impedance in the MMBZ5225BS-7-F indicates improved dynamic response characteristics. This parameter affects transient voltage regulation performance. The substitute provides superior impedance performance for the same Zener voltage and power rating.

Q: Why is the forward voltage specification different between the two parts?

A: The MMBZ5225BS-7-F specifies 900 mV @ 10 mA compared to 1 V @ 10 mA for the DZ4J030K0R. This represents improved forward conduction characteristics in the substitute part and does not prevent substitution.

Q: Are there supply chain advantages to using the MMBZ5225BS-7-F?

A: Yes. The MMBZ5225BS-7-F is classified as Active with 17,100 pieces in stock, compared to the obsolete DZ4J030K0R. Active product status ensures continued availability and manufacturing support.

Q: What packaging format is the MMBZ5225BS-7-F supplied in?

A: The MMBZ5225BS-7-F is supplied in Tape & Reel (TR) format with SOT-363 package configuration, suitable for automated assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications. The MMBZ5225BS-7-F additionally carries RoHS3 Compliance and REACH Unaffected certifications, meeting current environmental regulations.
