S1AB-13-G Equivalent & Substitute Parts

Part Overview

The S1AB-13-G is a general-purpose diode manufactured by Diodes Incorporated in the SMB (DO-214AA) surface mount package. This component is classified as obsolete, indicating it is no longer in active production. The S1AB-13-G remains available in inventory (726 pcs) as new original stock. Due to its obsolete status, identification of functionally equivalent active alternatives is necessary for ongoing design support, production continuity, and long-term component sourcing strategies.

Substitute Part Grouping Explanation

The S1AB-13-G has been identified with one direct substitute: the S1AB-13-F. This substitution is valid based on the following criteria:

Substitution Basis:

• Identical manufacturer (Diodes Incorporated)
• Identical package type (SMB / DO-214AA)
• Identical base product series (S1A)
• Matching compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Identical moisture sensitivity level (MSL 1)
• Identical electrical classification (general-purpose rectifier diode)

The S1AB-13-F is an active product with significantly higher inventory availability (39,697 pcs), providing reliable long-term sourcing compared to the obsolete S1AB-13-G.

Parameter Comparison

Engineering Selection Recommendations

The S1AB-13-F is the direct equivalent for the obsolete S1AB-13-G. Selection of the S1AB-13-F is supported by:

1. Identical Physical Form Factor: Both components use the SMB (DO-214AA) surface mount package, ensuring direct PCB footprint compatibility without layout modifications.

2. Regulatory and Compliance Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity classification, satisfying environmental and regulatory requirements without additional qualification.

3. Active Product Status: The S1AB-13-F is an active product with substantial inventory availability, eliminating obsolescence risk and ensuring long-term procurement viability.

4. Manufacturer Continuity: Both parts are manufactured by Diodes Incorporated, maintaining supply chain consistency and technical support continuity.

5. Electrical Specifications: The S1AB-13-F provides documented electrical parameters (50 V reverse voltage, 1 A average rectified current) consistent with general-purpose rectifier applications in the SMB package category.

Frequently Asked Questions (FAQ)

Q: Can the S1AB-13-F be used as a direct replacement for the S1AB-13-G without PCB modifications?

A: Yes. Both components use the identical SMB (DO-214AA) surface mount package. No PCB layout changes are required for substitution.

Q: What is the primary reason for substituting the S1AB-13-G?

A: The S1AB-13-G is classified as obsolete and no longer in active production. The S1AB-13-F is an active product from the same manufacturer, providing reliable long-term availability and production support.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both the S1AB-13-G and S1AB-13-F maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, and EAR99 export classification.

Q: What are the electrical specifications of the S1AB-13-F?

A: The S1AB-13-F is rated for 50 V DC reverse voltage with 1 A average rectified current. Forward voltage is 1.1 V maximum at 1 A. Reverse recovery time is 3 µs with reverse leakage current of 5 µA at 50 V.

Q: Is the S1AB-13-F available in the same packaging format?

A: Yes. The S1AB-13-F is supplied in Tape & Reel (TR) format in the SMB package, standard for surface mount production environments.

Q: What is the moisture sensitivity level for the S1AB-13-F?

A: The S1AB-13-F has a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Are there any temperature operating range differences?

A: The S1AB-13-F operates across a junction temperature range of -65°C to 150°C, suitable for industrial and commercial applications.
