Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KS8993FL is determined by the following critical parameters:

Functional Equivalence: Device type must be 10/100 Integrated Switch with identical port switch and network interface application capability.

Package Compatibility: Substitute parts must utilize the 128-BFQFP package configuration with 128-PQFP (14x20) supplier device package specification to ensure PCB footprint and assembly process compatibility.

Mounting Technology: Surface mount mounting type is required for compatibility with existing assembly processes.

Environmental & Compliance Specifications: Moisture Sensitivity Level must be MSL 3 (168 Hours). Export control classification (ECCN 5A991B1) and tariff classification (HTSUS 8542.39.0001) must align.

Manufacturer: Microchip Technology maintains the design and manufacturing specifications for this product family.

Based on these criteria, the KSZ8993FL qualifies as a direct substitute for the KS8993FL.

Parameter Comparison

Engineering Selection Recommendations

The KSZ8993FL is the direct substitute for the obsolete KS8993FL. Both components share identical functional specifications, package configurations, and electrical parameters required for 10/100 integrated switch applications.

Product Status Consideration: The KS8993FL is obsolete with limited remaining inventory (1209 pcs). The KSZ8993FL maintains active product status with significantly higher inventory availability (15413 pcs), ensuring long-term supply chain continuity.

Compliance Advantage: The KSZ8993FL achieves ROHS3 compliance, whereas the KS8993FL is RoHS non-compliant. For new designs or systems subject to RoHS regulatory requirements, the KSZ8993FL provides compliance alignment. Both components maintain identical REACH unaffected status and export control classifications.

Implementation: Direct substitution of KSZ8993FL for KS8993FL requires no design modifications. PCB footprint, assembly process parameters, and electrical interface specifications remain unchanged. Existing test procedures and functional validation protocols apply without revision.
