MA2S1110GL Equivalent & Substitute Parts

Part Overview

The MA2S1110GL is a general-purpose rectifier diode manufactured by Panasonic Electronic Components, rated for 80V DC reverse voltage and 100mA average rectified current. This component is classified as a small-signal diode with surface mount packaging in the SC-79/SOD-523 form factor. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA2S1110GL is determined by equivalence across the following critical electrical parameters:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 80V minimum
• Current - Average Rectified (Io): 100mA minimum
• Voltage - Forward (Vf) (Max) @ If: 1.2V maximum at 100mA
• Operating Temperature - Junction (Max): 150°C minimum
• Mounting Type: Surface Mount
• Technology: Standard

Secondary Compatibility Factors:

• Reverse Recovery Time (trr): Performance within small-signal classification
• Current - Reverse Leakage @ Vr: Acceptable for general-purpose rectification
• Capacitance @ Vr, F: Acceptable for general-purpose rectification
• Moisture Sensitivity Level (MSL): 1 (Unlimited) or equivalent

The substitute part 1SS387CT,L3F meets all primary matching criteria and maintains functional equivalence despite differences in package form factor (CST2 vs. SSMini2-F4) and minor variations in secondary parameters. Both parts operate within the small-signal diode classification and share identical maximum voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

The 1SS387CT,L3F from Toshiba Semiconductor and Storage is a functionally equivalent substitute for the obsolete MA2S1110GL. Both components share identical maximum voltage (80V), current (100mA), and forward voltage (1.2V @ 100mA) specifications, ensuring electrical interchangeability in general-purpose rectification applications.

Compliance and Availability Advantages:

The 1SS387CT,L3F holds Active product status with 20,200 units in stock, compared to the MA2S1110GL's Obsolete status with limited inventory. The substitute part carries RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in restricted substance directives.

Package Form Factor Consideration:

The primary design difference is the package form factor: the MA2S1110GL uses SC-79/SOD-523 (SSMini2-F4), while the 1SS387CT,L3F uses SOD-882 (CST2). Both are surface mount packages suitable for automated assembly. PCB layout modifications may be required to accommodate the different footprint dimensions, but electrical performance remains equivalent.

Secondary Parameter Variations:

The 1SS387CT,L3F exhibits a slightly higher reverse recovery time (4ns vs. 3ns) and higher reverse leakage current (500nA @ 80V vs. 100nA @ 75V), both of which remain acceptable for general-purpose rectification applications. The lower junction capacitance (0.5pF vs. 2pF) of the substitute part provides improved high-frequency performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1SS387CT,L3F directly replace the MA2S1110GL without circuit modifications?

A: Electrical substitution is direct due to identical voltage, current, and forward voltage ratings. However, the different package form factor (SOD-882 vs. SC-79/SOD-523) requires PCB layout redesign to accommodate the new footprint dimensions. No circuit topology changes are necessary.

Q: What is the significance of the different reverse recovery times (3ns vs. 4ns)?

A: Both parts are classified as small-signal diodes with recovery times suitable for general-purpose rectification. The 1ns difference does not impact performance in standard rectification circuits. Applications requiring precise switching characteristics should verify timing requirements against both specifications.

Q: Why does the substitute part have higher reverse leakage current?

A: The 1SS387CT,L3F exhibits 500nA @ 80V compared to the MA2S1110GL's 100nA @ 75V. This difference remains within acceptable limits for general-purpose rectification. Both values are typical for small-signal diodes in this voltage and current class and do not affect circuit functionality in standard applications.

Q: Is the lower capacitance of the substitute part (0.5pF vs. 2pF) advantageous?

A: Lower junction capacitance in the 1SS387CT,L3F provides improved performance at higher frequencies and faster switching transitions. This represents an enhancement over the original part for applications sensitive to capacitive effects.

Q: What are the packaging implications of switching from SSMini2-F4 to CST2?

A: Both packages are surface mount formats suitable for automated pick-and-place assembly. The CST2 package (SOD-882) has different physical dimensions than the SSMini2-F4 (SC-79/SOD-523). Design engineers must update PCB artwork, solder paste stencils, and pick-and-place machine programming to accommodate the new footprint.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: RoHS3 compliance of the 1SS387CT,L3F ensures the part meets current environmental and restricted substance regulations. This is advantageous for new designs and production runs subject to RoHS directives. The obsolete MA2S1110GL may not carry current compliance certifications.

Q: Can both parts be used interchangeably in existing inventory?

A: No. Due to different package form factors, the parts cannot be used interchangeably in existing PCB designs without layout modifications. Separate PCB revisions are required for each part number.
