SD103AWS Equivalent & Substitute Parts

Part Overview

The SD103AWS is a 40 V, 350 mA small signal Schottky diode manufactured by ANBON SEMICONDUCTOR (INT'L) LIMITED. This component is a surface mount rectifier in the SOD-323 package, designed for fast recovery applications with a reverse recovery time of 10 ns. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required for production processes, or when sourcing from different manufacturers is preferred for supply chain optimization. All substitute parts listed maintain identical electrical performance and mechanical compatibility with the SD103AWS.

Substitute Part Grouping Explanation

All substitute parts for the SD103AWS are classified as parametric equivalents. Substitution is valid based on the following criteria:

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
Reverse Recovery Time (trr): 10 ns
Current - Reverse Leakage @ Vr: 5 µA @ 30 V
Capacitance @ Vr, F: 50 pF @ 0V, 1MHz

Mechanical Parameters (Must Match):

Package / Case: SC-76, SOD-323
Mounting Type: Surface Mount
Supplier Device Package: SOD-323

Compliance Parameters (Must Match):

Technology: Schottky
Operating Temperature - Junction: -55°C to 125°C
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts may differ in packaging format (Cut Tape vs. Tape & Reel) and manufacturer identity. Two substitute parts include automotive-grade qualification (AEC-Q101), which represents an additional certification level beyond the base requirements.

Frequently Asked Questions (FAQ)

Q: Can SD103AWS-E3-08 be used as a direct replacement for SD103AWS?

A: Yes. SD103AWS-E3-08 is a parametric equivalent with identical electrical specifications, operating temperature range, and package type (SOD-323). The difference is packaging format: SD103AWS-E3-08 is supplied in Tape & Reel format, while SD103AWS is supplied in Cut Tape & Digi-Reel format. Both are suitable for surface mount assembly.

Q: What is the difference between SD103AWS-HE3-18 and SD103AWS-G3-18?

A: Both parts are identical in electrical performance and package type. SD103AWS-HE3-18 includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring formal qualification documentation. SD103AWS-G3-18 does not carry automotive qualification. Both are supplied in Cut Tape format.

Q: Are the automotive-qualified parts (SD103AWS-HE3-18 and SD103AWSHE3-TP) required for non-automotive applications?

A: No. Automotive qualification is an additional certification level. For non-automotive applications, any of the listed substitute parts with matching electrical and mechanical parameters are suitable. Automotive-qualified parts can be used in non-automotive applications without issue.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) is supplied in individual tape segments, typically for lower-volume or manual assembly processes. Tape & Reel (TR) is supplied on continuous reels, optimized for high-volume automated assembly. Both formats contain the same component in the same SOD-323 package. Selection depends on assembly equipment and production volume requirements.

Q: Can I substitute SD103AWSHE3-TP (Micro Commercial Co) for SD103AWS (ANBON SEMICONDUCTOR)?

A: Yes. SD103AWSHE3-TP is a parametric equivalent with identical electrical specifications, operating temperature range, and SOD-323 package type. The manufacturer differs (Micro Commercial Co vs. ANBON SEMICONDUCTOR), and SD103AWSHE3-TP includes AEC-Q101 automotive qualification. Both are ROHS3 compliant with unlimited MSL rating.

Q: Are all substitute parts in active production status?

A: Yes. All substitute parts listed (SD103AWS-E3-08, SD103AWS-E3-18, SD103AWS-G3-18, SD103AWS-HE3-18, and SD103AWSHE3-TP) are in active production status with current inventory availability.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) rating, matching the compliance profile of the SD103AWS.
