Substitute Part Grouping Explanation

The KSZ8993ML qualifies as a direct substitute for the KS8993ML based on the following alignment of critical parameters:

Functional Equivalence: Both parts are 10/100 Integrated Switches with identical device type classification and application scope (Port Switch/Network Interface).

Package Compatibility: Both parts utilize the 128-BFQFP package (128-PQFP 14x20 form factor) with surface mount mounting type, ensuring PCB layout and assembly process compatibility without modification.

Environmental Specifications: Both parts share identical Moisture Sensitivity Level (MSL 3, 168 Hours), ECCN classification (5A991B1), and HTSUS code (8542.39.0001), confirming equivalent handling and regulatory treatment.

Compliance Differences: The primary distinction is RoHS status. The KS8993ML is RoHS non-compliant, while the KSZ8993ML is ROHS3 compliant. Both maintain REACH Unaffected status.

Product Availability: The KS8993ML is obsolete with limited inventory (718 Pcs). The KSZ8993ML is active with substantial inventory (1,000,199 Pcs), providing long-term procurement security.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The KSZ8993ML is the recommended substitute for the KS8993ML in all new designs and procurement activities.

Justification:

1. Product Status: The KSZ8993ML maintains active product status with Microchip Technology, ensuring continued manufacturing support, technical documentation availability, and long-term supply chain stability. The KS8993ML is obsolete, presenting procurement risk and limited inventory availability.

2. Regulatory Compliance: The KSZ8993ML is ROHS3 compliant, meeting current environmental and material composition requirements for most markets and applications. The KS8993ML's non-compliant status may restrict use in regulated industries and regions with RoHS enforcement.

3. Functional and Mechanical Compatibility: Both parts are functionally identical 10/100 Integrated Switches in the same 128-BFQFP package with identical electrical and environmental specifications. No circuit redesign or PCB layout modification is required.

4. Inventory and Availability: The KSZ8993ML has substantial inventory (1,000,199 Pcs), supporting both immediate procurement and long-term production requirements without supply constraints.

Implementation: Direct substitution of KSZ8993ML for KS8993ML requires no design changes, PCB modifications, or firmware updates. The parts are pin-compatible and functionally equivalent.
