Substitute Part Grouping Explanation

The S1KB-13-G is directly substituted by the S1KB-13-F, which is manufactured by the same supplier, Diodes Incorporated. The substitution is valid based on the following criteria:

Substitution Basis:

• Identical manufacturer (Diodes Incorporated)
• Same base product number (S1K series)
• Equivalent functional classification (general-purpose rectifier diode)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity rating (MSL 1 - Unlimited)
• Identical REACH status (REACH Unaffected)
• Same package type (SMB/DO-214AA)
• Active product status (S1KB-13-F is currently in production)

The S1KB-13-F provides the same electrical performance envelope required for general-purpose rectification applications while maintaining full compliance with current regulatory requirements.

Engineering Selection Recommendations

The S1KB-13-F is the direct equivalent for the obsolete S1KB-13-G. Selection of the S1KB-13-F is appropriate for the following reasons:

Compliance and Regulatory Status:

• Both components maintain ROHS3 compliance, ensuring compatibility with current environmental regulations
• Both components carry REACH Unaffected status, confirming no restricted substance concerns
• Both components share identical moisture sensitivity classification (MSL 1), eliminating special handling requirement changes

Product Availability:

• The S1KB-13-G is obsolete with limited remaining inventory (779 Pcs)
• The S1KB-13-F is an active product with substantial inventory availability (18,400 Pcs), ensuring long-term procurement viability

Functional Equivalence:

• Both components are manufactured by Diodes Incorporated within the same product series (S1K base number)
• Both utilize identical SMB/DO-214AA surface-mount packaging
• The S1KB-13-F provides documented electrical specifications (800 V reverse voltage, 1 A average rectified current) consistent with general-purpose rectifier applications

Frequently Asked Questions (FAQ)

Q: Can the S1KB-13-F directly replace the S1KB-13-G in existing designs?

A: Yes. The S1KB-13-F is the direct manufacturer-designated equivalent. Both components share identical package geometry (SMB/DO-214AA), mounting type (surface mount), and regulatory compliance status. No PCB layout modifications are required.

Q: What is the primary reason for substitution?

A: The S1KB-13-G is classified as obsolete. The S1KB-13-F is the active equivalent from the same manufacturer, ensuring continued availability and compliance with current manufacturing standards.
