MA2ZD180GL Equivalent & Substitute Parts

Part Overview

The MA2ZD180GL is a Schottky diode manufactured by Panasonic Electronic Components, rated for 20V DC reverse voltage with 500mA average rectified current. This component is packaged in the SMini2-F3 surface mount configuration and features fast recovery characteristics with a 7 nanosecond reverse recovery time. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the MA2ZD180GL is determined by equivalence in the following critical parameters: Schottky diode technology, 20V maximum reverse voltage rating, surface mount packaging compatibility, and fast recovery characteristics. The SD103CWS-7-F qualifies as a substitute based on matching voltage classification and technology type. However, the average rectified current rating differs between the main part (500mA) and the substitute (350mA), which represents a functional limitation in the substitute component. Both components maintain fast recovery operation with reverse recovery times within acceptable ranges for high-frequency switching applications. Moisture sensitivity classification and operating temperature maximum ratings are equivalent across both parts.

Engineering Selection Recommendations

The SD103CWS-7-F from Diodes Incorporated serves as an active substitute for the obsolete MA2ZD180GL. Both components share identical 20V reverse voltage ratings and Schottky diode technology, with equivalent fast recovery performance and moisture sensitivity classifications. The substitute maintains active product status with established supply chain availability, addressing the obsolescence constraint of the original part.

Design consideration: The SD103CWS-7-F carries a reduced average rectified current rating of 350mA compared to the MA2ZD180GL's 500mA specification. Circuit designs operating at or near the 500mA threshold require thermal and current distribution analysis to confirm compatibility with the lower-rated substitute. The substitute exhibits superior reverse leakage characteristics (5µA at 10V versus 200µA at 20V) and reduced junction capacitance (28pF versus 100pF), which may provide performance benefits in high-frequency switching applications.

The SD103CWS-7-F is RoHS3 compliant and REACH unaffected, meeting contemporary regulatory requirements. Both components are classified under identical ECCN and HTSUS codes.

Frequently Asked Questions (FAQ)

Q: Can the SD103CWS-7-F directly replace the MA2ZD180GL in all applications?

A: Direct replacement is possible for applications operating below 350mA average rectified current. Applications requiring the full 500mA rating of the original part require circuit redesign or parallel device configuration to maintain current capacity.

Q: What are the package compatibility considerations?

A: Both components use SOD-323 surface mount packaging. The MA2ZD180GL is supplied in SMini2-F3 configuration while the SD103CWS-7-F uses standard SOD-323 format. Physical footprint compatibility should be verified against PCB layout specifications, as minor dimensional variations may exist between supplier device packages.

Q: How do the forward voltage characteristics compare?

A: The MA2ZD180GL specifies 420mV forward voltage at 500mA, while the SD103CWS-7-F specifies 600mV at 200mA. Direct comparison at identical current levels is not available from the provided specifications. Circuit designs sensitive to forward voltage drop require detailed analysis of operating current conditions.

Q: Are there compliance or certification differences?

A: The SD103CWS-7-F carries RoHS3 compliance and REACH unaffected status. Both components share EAR99 ECCN classification and identical HTSUS codes. The substitute meets current regulatory requirements for commercial and industrial applications.

Q: What is the significance of the reverse recovery time difference?

A: The MA2ZD180GL exhibits 7ns reverse recovery time while the SD103CWS-7-F exhibits 10ns. Both remain within fast recovery classification for switching frequencies below 100MHz. High-frequency switching applications above 50MHz should evaluate the 3ns difference for potential performance impact.
