89HPES8T5AZBBCGI Equivalent & Substitute Parts

Part Overview

The 89HPES8T5AZBBCGI is a specialized interface IC manufactured by Renesas Electronics Corporation, designed for switch interfacing applications using PCI Express protocol. This component is packaged in a 196-CABGA (15x15) ball grid array format and operates at 3.3V supply voltage. The product is classified as obsolete, making identification of functionally equivalent substitute parts essential for system redesign, legacy system maintenance, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 89HPES8T5AZBBCGI are identified based on the following critical parameters:

• Interface Protocol: PCI Express compatibility
• Application Category: Switch interfacing or fanout PCIe switch functionality
• Mounting Type: Surface mount technology
• Compliance Standards: ROHS3 compliance and REACH unaffected status
• Supply Voltage Compatibility: Operating voltage requirements

The substitute parts listed below maintain functional equivalence within the interface IC category while accommodating variations in package form factor and product lifecycle status. Two substitutes (PM8561B-F3EI and PM8532B-F3EI) represent active products from Microchip Technology's Switchtec series, while PCI9052 G represents a legacy alternative from Broadcom Limited.

Parameter Comparison

Engineering Selection Recommendations

PM8561B-F3EI and PM8532B-F3EI are the primary recommended substitutes for new designs and system upgrades. Both parts are manufactured by Microchip Technology and maintain active product status, ensuring long-term availability and supply chain stability. These components are part of the Switchtec series, specifically designed for fanout PCIe switch applications. Both maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The higher moisture sensitivity level (MSL 4) requires appropriate handling during storage and assembly compared to the original part.

PCI9052 G from Broadcom Limited represents a legacy alternative suitable only for direct replacement scenarios where the original 89HPES8T5AZBBCGI cannot be sourced. This part operates at 5V supply voltage and uses PCI protocol rather than PCI Express, making it suitable only for systems with compatible electrical and protocol requirements. Its obsolete status limits its viability for new procurement.

Frequently Asked Questions (FAQ)

Q: Can PM8561B-F3EI directly replace 89HPES8T5AZBBCGI in existing designs?

A: PM8561B-F3EI provides functional equivalence for PCI Express switch interfacing applications. However, the package form factor differs (650-FCBGA versus 196-CABGA), requiring PCB redesign. The higher moisture sensitivity level (MSL 4 versus MSL 3) necessitates updated handling procedures during manufacturing.

Q: What is the primary advantage of PM8532B-F3EI as a substitute?

A: PM8532B-F3EI maintains active product status and PCI Express interface compatibility. Its module package format may simplify integration in certain system architectures, though specific mechanical and electrical interface requirements must be verified against system specifications.

Q: Why is PCI9052 G listed as a substitute if it uses PCI instead of PCI Express?

A: PCI9052 G is included as a legacy alternative for systems where protocol downgrade is acceptable or where the original design accommodates both PCI and PCI Express interfaces. Its 5V supply voltage requirement represents a significant electrical difference from the 3.3V original part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (PM8561B-F3EI, PM8532B-F3EI, and PCI9052 G) maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards.

Q: What handling considerations apply to the substitute parts?

A: PM8561B-F3EI and PM8532B-F3EI have MSL 4 (72 hours) moisture sensitivity, compared to MSL 3 (168 hours) for the original part. This requires stricter moisture control during storage, with components maintained in dry-pack conditions and baked before assembly if exposure limits are exceeded.
