Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KS8993M is determined by strict alignment of the following critical parameters:

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

Package Compatibility: The substitute must use the 128-BFQFP package type with 128-PQFP (14x20mm) supplier device package specifications to ensure PCB footprint and assembly process compatibility.

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

Environmental & Compliance Alignment: RoHS3 compliance, MSL 3 rating (168 hours), and REACH Unaffected status must be maintained to ensure regulatory and operational consistency.

Manufacturer: Microchip Technology as the original manufacturer ensures design continuity and technical support consistency.

The KSZ8993M meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support: The KSZ8993M is the appropriate substitute for KS8993M applications. Both components share identical electrical specifications, package geometry, and compliance certifications. The KSZ8993M maintains Active product status with Microchip Technology, ensuring continued availability and technical support.

Compliance Verification: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for existing designs. MSL 3 moisture sensitivity ratings are equivalent, requiring identical handling and storage protocols.

Inventory Considerations: The KSZ8993M is available in Tray packaging with 1256 units in current stock, compared to the obsolete KS8993M. Selection of the active substitute ensures long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can KSZ8993M directly replace KS8993M in existing designs?

A: Yes. Both parts are 10/100 Integrated Switch ICs with identical 128-PQFP (14x20) package specifications, surface mount mounting type, and functional applications. PCB footprint and assembly compatibility are maintained.

Q: Are there differences in packaging format between these parts?

A: The KS8993M original part is listed with standard packaging, while the KSZ8993M substitute is supplied in Tray format. Both use the same 128-BFQFP package type and 128-PQFP (14x20) device package. Tray packaging is standard for active production parts and does not affect component functionality or performance.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both KS8993M and KSZ8993M are ROHS3 compliant, carry MSL 3 (168 hours) moisture sensitivity ratings, and maintain REACH Unaffected status. Handling, storage, and assembly requirements are identical.

Q: Why is KS8993M marked as Obsolete?

A: The KS8993M has reached end-of-life status with Microchip Technology. The KSZ8993M represents the active production equivalent, ensuring continued availability and manufacturer support for new and legacy applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching device type (10/100 Integrated Switch), package specification (128-BFQFP / 128-PQFP 14x20), mounting technology (Surface Mount), functional application (Port Switch / Network Interface), and compliance certifications (ROHS3, MSL 3, REACH Unaffected).
