Key Parameters

Substitute Part Grouping Explanation

Substitution of the KS8893MQL is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 128-BFQFP package with 128-PQFP (14x20) supplier device package specification. This ensures mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Manufacturer Consistency: Microchip Technology manufactures both the obsolete KS8893MQL and its active equivalent. Maintaining manufacturer consistency ensures design validation and supply chain continuity.

Functional Classification: The substitute part must operate as a 10/100 Integrated Switch with equivalent switching and network interface capabilities.

Compliance Standards: Both parts must maintain ROHS3 compliance, identical MSL rating of 3 (168 Hours), and REACH Unaffected status to ensure regulatory and environmental compatibility.

Base Product Number: The KS8893 base product number identifies the core product family, with variant designations (KS8893MQL vs. KSZ8893MQL) representing different product lifecycle stages.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: KSZ8893MQL is the direct equivalent for KS8893MQL applications.

Justification: The KSZ8893MQL maintains identical package specifications (128-BFQFP, 128-PQFP 14x20), identical compliance certifications (ROHS3, REACH Unaffected), and identical MSL rating (3, 168 Hours). The substitute part is manufactured by the same supplier (Microchip Technology) and operates within the same product family (KS8893/KSZ8893 base product numbers).

Product Status Advantage: The KSZ8893MQL holds active product status, ensuring long-term availability, ongoing technical support, and supply chain stability compared to the obsolete KS8893MQL.

Compliance Continuity: Both parts satisfy identical regulatory requirements, eliminating the need for design re-validation or compliance re-certification when transitioning from the main part to the substitute.

Frequently Asked Questions (FAQ)

Q: Why is the KS8893MQL classified as obsolete?

A: The KS8893MQL has reached end-of-life status within Microchip Technology's product portfolio. The KSZ8893MQL represents the active continuation of this product line with equivalent functionality and identical package specifications.

Q: Are the KS8893MQL and KSZ8893MQL pin-compatible?

A: Both parts utilize the 128-BFQFP package with 128-PQFP (14x20) dimensions. Pin compatibility is ensured by identical package specifications. PCB layouts designed for KS8893MQL can accommodate KSZ8893MQL without modification.

Q: What is the difference between the KS8893MQL and KSZ8893MQL part numbers?

A: The designation change from KS8893 to KSZ8893 reflects Microchip Technology's product lifecycle management. The KSZ8893MQL is the active equivalent with enhanced specifications and ongoing support. Both parts share the same functional classification as 10/100 Integrated Switches.

Q: Do both parts meet the same compliance standards?

A: Yes. Both KS8893MQL and KSZ8893MQL are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours). No compliance re-validation is required when substituting between these parts.

Q: What packaging options are available for the KSZ8893MQL?

A: The KSZ8893MQL is supplied in Tray packaging. The KS8893MQL packaging specification was not provided in the available documentation.

Q: Can I use KSZ8893MQL as a direct replacement in existing designs?

A: Yes. The KSZ8893MQL is a direct substitute for KS8893MQL applications. Identical package specifications, compliance certifications, and MSL ratings ensure compatibility with existing PCB designs and assembly processes without design modification.

Q: What is the supply status for these parts?

A: KS8893MQL inventory is limited (1076 Pcs available). KSZ8893MQL is actively manufactured with higher inventory availability (4868 Pcs available), making it the recommended choice for new designs and ongoing procurement.
