Key Parameters

Substitute Part Grouping Explanation

Substitution of the KS8993I is determined by strict alignment of the following critical parameters:

Functional Equivalence Criteria:

• Identical device type: 10/100 Integrated Switch
• Identical package format: 128-BFQFP / 128-PQFP (14x20)
• Identical mounting technology: Surface Mount
• Identical application category: Port Switch / Network Interface
• Identical manufacturer: Microchip Technology

Compliance & Environmental Criteria:

• Moisture Sensitivity Level: MSL 3 (168 Hours)
• ECCN classification: 5A991B1
• REACH regulatory status: REACH Unaffected

The KSZ8995MAI meets all functional and environmental parameters required for direct substitution. This part maintains identical electrical specifications, mechanical compatibility, and regulatory classification while offering the advantage of Active product status and improved RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance: The KSZ8995MAI is the direct functional equivalent for KS8993I replacement in existing designs. Both components share identical electrical specifications, package geometry, and pin configuration, enabling direct PCB-level substitution without design modification.

Product Status Consideration: The KS8993I is classified as Obsolete, indicating discontinued manufacturing and end-of-life status. The KSZ8995MAI maintains Active product status with ongoing manufacturer support, ensuring long-term availability and supply chain stability for production and field service applications.

Compliance Advantage: While the KS8993I is RoHS non-compliant, the KSZ8995MAI achieves ROHS3 compliance. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating compliant component sourcing.

Environmental Handling: Both parts maintain identical MSL 3 (168 Hours) moisture sensitivity classification, requiring equivalent storage, handling, and reflow procedures. No changes to manufacturing process parameters are necessary.
