Substitute Part Grouping Explanation

The S1MB-13-G has been identified with one direct substitute: the S1MB-13-F. This substitution is valid based on the following alignment criteria:

Manufacturer Consistency: Both parts are manufactured by Diodes Incorporated, ensuring design validation and quality standards remain consistent.

Package Compatibility: Both components utilize the SMB (DO-214AA) surface mount package, enabling direct physical and electrical integration into existing PCB layouts without modification.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity level (MSL 1), satisfying regulatory and environmental requirements.

Electrical Classification: Both are general-purpose rectifier diodes within the same product family (base product number S1M), confirming functional equivalence for standard rectification applications.

The S1MB-13-F is the active production equivalent, with significantly higher inventory availability (30,200 pcs) and confirmed active product status, making it the primary substitute for the obsolete S1MB-13-G.

Engineering Selection Recommendations

The S1MB-13-F is the appropriate substitute for the obsolete S1MB-13-G based on the following engineering criteria:

Product Status Transition: The S1MB-13-F maintains active production status with confirmed inventory availability of 30,200 units, ensuring long-term supply chain viability compared to the obsolete S1MB-13-G.

Regulatory Compliance: Both components satisfy identical compliance requirements (ROHS3, REACH unaffected, EAR99 ECCN classification), eliminating compliance risk during substitution.

Physical Integration: The SMB package specification is identical between both parts, enabling direct PCB layout compatibility without redesign or rework.

Manufacturer Continuity: Diodes Incorporated manufactures both components, maintaining consistent quality standards, device characterization, and technical support resources.

For applications where the S1MB-13-G was previously specified, the S1MB-13-F provides equivalent functionality with the advantage of active production status and superior inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the S1MB-13-F be used as a direct replacement for the S1MB-13-G without PCB modification?

A: Yes. Both components use the identical SMB (DO-214AA) surface mount package, enabling direct substitution on existing PCB layouts without physical modification or rework.

Q: What is the primary reason for substituting the S1MB-13-G?

A: The S1MB-13-G is classified as obsolete and no longer in active production. The S1MB-13-F is the active equivalent from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between the S1MB-13-G and S1MB-13-F?

A: No. Both components maintain identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), and EAR99 ECCN classification.

Q: What are the electrical specifications of the S1MB-13-F?

A: The S1MB-13-F is rated for 1000 V DC reverse voltage with 1 A average rectified current. Forward voltage is 1.1 V maximum at 1 A, with 3 µs reverse recovery time and 5 µA reverse leakage current at 1000 V.

Q: Is the S1MB-13-F available in the same packaging options as the S1MB-13-G?

A: The S1MB-13-F is available in Cut Tape (CT) and Digi-Reel® packaging formats, both utilizing the SMB surface mount package specification.

Q: What is the operating temperature range for the S1MB-13-F?

A: The S1MB-13-F operates across a junction temperature range of -65°C to 150°C, suitable for standard industrial and commercial applications.

Q: Are both parts from the same manufacturer product family?

A: Yes. Both the S1MB-13-G and S1MB-13-F share the base product number S1M, confirming they are part of the same Diodes Incorporated product family.
