SD103AWSL-TP Equivalent & Substitute Parts

Part Overview

The SD103AWSL-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 40 V DC reverse voltage and 350 mA average rectified current in a surface mount SOD-323FL package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameters. Alternative sources for the SD103AWSL-TP are necessary to support supply chain flexibility, inventory availability, and design continuity in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD103AWSL-TP is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 350 mA
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 200 mA
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: SC-90, SOD-323F
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core parameters. Secondary parameters such as reverse recovery time, reverse leakage current at specific voltages, and capacitance values may vary within acceptable ranges for the diode category without affecting functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical equivalence to the SD103AWSL-TP across all critical parameters. Selection between the main part and substitutes is based on the following factors:

SD103AWSL-TP (Micro Commercial Co): Primary source component with 2,622 units in stock. Maintains all specified electrical characteristics and compliance requirements.

SD103AWS-AU_R1_000A1 (Panjit International Inc.): Parametric equivalent with automotive-grade qualification (AEC-Q101) and 17,083 units in stock. Includes additional automotive qualification certification. Reverse leakage current measured at 40 V instead of 30 V. Capacitance specified at 10pF @ 4V, 1MHz.

SD103AWS_R1_00001 (Panjit International Inc.): Parametric equivalent with 29,610 units in stock. Reverse leakage current measured at 30 V, matching the main part specification. Capacitance value not specified in available data.

All three parts are RoHS3 compliant, Active product status, and suitable for direct substitution in applications requiring 40 V, 350 mA Schottky rectifier diodes in SOD-323F surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can SD103AWS-AU_R1_000A1 and SD103AWS_R1_00001 be used interchangeably with SD103AWSL-TP?

A: Yes. Both Panjit parts are parametric equivalents meeting the core electrical specifications: 40 V reverse voltage, 350 mA average rectified current, 600 mV forward voltage at 200 mA, and fast recovery characteristics. All three parts use identical SOD-323F surface mount packages and are RoHS3 compliant.

Q: What is the difference between the two Panjit substitute parts?

A: SD103AWS-AU_R1_000A1 includes AEC-Q101 automotive qualification and specifies reverse leakage current at 40 V with capacitance data (10pF @ 4V, 1MHz). SD103AWS_R1_00001 specifies reverse leakage current at 30 V and does not include capacitance specification. Both maintain identical electrical performance for the primary diode function.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the SC-90, SOD-323F surface mount package with identical mechanical dimensions and land pattern requirements. Direct PCB substitution is supported without layout modifications.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). ECCN and HTSUS classifications are identical across all parts.

Q: What is the significance of the reverse leakage current measurement voltage difference?

A: Reverse leakage current is measured at different voltages (30 V for SD103AWSL-TP and SD103AWS_R1_00001; 40 V for SD103AWS-AU_R1_000A1) but all specify 5 µA maximum. This represents normal variation in manufacturer test conditions and does not affect functional equivalence for circuit applications.

Q: Which substitute part should be selected for automotive applications?

A: SD103AWS-AU_R1_000A1 is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive-grade requirements. The other parts are suitable for general industrial and commercial applications.
