Equivalent & Substitute Parts: MA2J73200L

Part Overview

The MA2J73200L is a Schottky diode manufactured by Panasonic Electronic Components, rated for 30V DC reverse voltage and 30mA average rectified current in a surface mount SMini2-F1 package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility while meeting current manufacturing and supply chain standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA2J73200L is based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Voltage rating equal to or greater than 30V DC reverse voltage
• Schottky diode technology
• Surface mount package compatibility (SOD-323F / SC-90)
• Small signal classification (≤200mA)

Acceptable Parameter Variations:

• Current rating may exceed the original 30mA specification, provided the substitute operates within the same small signal category (≤200mA)
• Forward voltage characteristics may differ within the small signal operating range
• Reverse leakage current may vary within acceptable limits for the voltage class
• Capacitance values may differ due to different semiconductor geometries

The PMEG3002EJ,115 meets all primary substitution criteria and operates within the defined small signal category, making it a valid electrical equivalent despite higher current rating and different secondary characteristics.

Engineering Selection Recommendations

PMEG3002EJ,115 as Primary Substitute:

The PMEG3002EJ,115 is the designated substitute for the obsolete MA2J73200L. This selection is based on:

1. Electrical Compatibility: Both components share identical 30V reverse voltage ratings and Schottky technology. The substitute's 200mA current rating exceeds the original 30mA specification, providing design margin for applications operating at or below the original current level.

2. Package Compatibility: Both components use SOD-323F surface mount packages, ensuring mechanical and thermal compatibility with existing PCB layouts.

3. Product Status: The PMEG3002EJ,115 maintains active production status with established supply chain availability (51,201 pieces in stock), eliminating obsolescence risk.

4. Compliance and Certification: The substitute carries AEC-Q100 automotive qualification and ROHS3 compliance, meeting modern regulatory requirements. The original MA2J73200L carries no specified automotive qualification.

5. Thermal Performance: The substitute's 150°C maximum junction temperature exceeds the original 125°C rating, providing enhanced thermal margin.

Design Considerations:

Applications requiring the exact 30mA current specification and 1ns reverse recovery time of the original component must evaluate the substitute's higher current rating (200mA) and longer recovery time (5ns) within circuit-level performance requirements. The substitute's higher capacitance (18pF versus 1.5pF) may affect high-frequency switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can the PMEG3002EJ,115 directly replace the MA2J73200L in all applications?

A: The PMEG3002EJ,115 is electrically compatible for applications operating at or below 30mA. The substitute's higher current rating and capacitance do not prevent substitution in circuits designed for the original 30mA specification. Circuit-level validation is required for applications sensitive to reverse recovery time or capacitance characteristics.

Q: Are the package dimensions identical between MA2J73200L and PMEG3002EJ,115?

A: Both components use SOD-323F surface mount packages (SC-90 designation). Package footprints and land patterns are compatible for direct PCB substitution.

Q: What is the difference between SMini2-F1 and SOD-323F package designations?

A: SMini2-F1 is Panasonic's proprietary package designation for the SOD-323F industry-standard package. Both designations refer to the same physical package form factor used in surface mount applications.

Q: Does the higher reverse leakage current (40µA versus 30µA) of the substitute affect circuit performance?

A: The 10µA difference in reverse leakage current at 30V is within acceptable tolerance for small signal Schottky diode applications. This parameter variation does not typically impact circuit functionality in standard rectification or switching applications.

Q: Why does the substitute have higher capacitance (18pF versus 1.5pF)?

A: Capacitance differences result from different semiconductor junction geometries and current ratings. The PMEG3002EJ,115's higher current capability produces larger junction capacitance. For applications sensitive to capacitive effects at high frequencies, circuit-level analysis is required.

Q: Is the PMEG3002EJ,115 suitable for automotive applications?

A: Yes. The PMEG3002EJ,115 carries AEC-Q100 qualification, meeting automotive industry reliability standards. The original MA2J73200L carries no automotive qualification designation.

Q: What is the impact of the 5ns reverse recovery time versus the original 1ns specification?

A: The 4ns difference in reverse recovery time affects switching speed in high-frequency applications. For circuits operating below 1MHz, this difference is negligible. High-frequency switching applications must evaluate the impact on circuit performance.
