Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KS8993MI is determined by the following critical parameters:

Functional Equivalence: Both parts must operate as 10/100 Integrated Switch ICs with identical port switch and network interface applications.

Package Compatibility: Both parts must use the 128-BFQFP package type with 128-PQFP (14x20) supplier device package specifications to ensure PCB footprint and assembly compatibility.

Mounting Technology: Both parts must employ surface mount technology for consistent manufacturing processes.

Electrical Specifications: Moisture Sensitivity Level (MSL) rating of 3 (168 Hours) must be maintained to ensure equivalent handling and storage requirements.

Manufacturer Consistency: Parts must originate from Microchip Technology to guarantee design compatibility and technical support alignment.

The KSZ8993MI meets all substitution criteria and is classified as a direct equivalent to the KS8993MI.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: KSZ8993MI is the direct substitute for KS8993MI applications.

Justification: The KSZ8993MI maintains identical electrical, mechanical, and functional specifications while offering active product status from Microchip Technology. This ensures ongoing technical support, documentation availability, and supply chain continuity.

Compliance Consideration: The KSZ8993MI achieves ROHS3 compliance, whereas the KS8993MI is RoHS non-compliant. Systems requiring RoHS compliance must use the KSZ8993MI. Legacy systems with RoHS non-compliance requirements may use either part based on procurement availability.

Regulatory Alignment: Both parts share identical ECCN (5A991B1) and HTSUS (8542.39.0001) classifications, ensuring consistent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can KSZ8993MI directly replace KS8993MI in existing designs?

A: Yes. The KSZ8993MI is a direct functional and mechanical equivalent. Both parts share identical package specifications (128-PQFP 14x20), mounting technology (surface mount), and application scope (10/100 port switch and network interface). No PCB redesign or layout modification is required.

Q: What is the primary difference between these parts?

A: The KSZ8993MI is an active product with ROHS3 compliance, while the KS8993MI is obsolete and RoHS non-compliant. Both maintain identical electrical performance and physical specifications.

Q: Are there packaging differences between KS8993MI and KSZ8993MI?

A: Both parts use 128-BFQFP package type with 128-PQFP (14x20) supplier device package. The KS8993MI is supplied in standard packaging, while KSZ8993MI is supplied in Tray packaging. Both are compatible with standard surface mount assembly processes.

Q: Does moisture sensitivity differ between these parts?

A: No. Both parts maintain MSL 3 (168 Hours) rating, requiring identical handling, storage, and reflow conditions.

Q: Which part should be selected for new designs?

A: KSZ8993MI is the appropriate selection for new designs due to active product status and ROHS3 compliance. This ensures long-term availability and regulatory alignment with current environmental standards.

Q: Are there supply chain differences?

A: KS8993MI is obsolete with limited inventory availability. KSZ8993MI is an active product with established supply channels through Microchip Technology and authorized distributors.
