PCI9052 G Equivalent & Substitute Parts

Part Overview

The PCI9052 G is a specialized I/O Accelerator Interface IC manufactured by Broadcom Limited, designed for PCI bus applications. This component operates at 5V supply voltage and is housed in a 160-QFP package (28x28mm). The product is currently classified as obsolete, making identification of suitable substitute components essential for legacy system maintenance and design updates. The PCI9052 series served as a foundational interface solution for I/O acceleration in PCI-based architectures.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCI9052 G requires evaluation based on the following critical parameters:

Interface Protocol Compatibility: The original component operates on PCI protocol. Substitute components must support equivalent or backward-compatible interface standards to maintain system functionality.

Package and Mounting Specifications: The 160-QFP (28x28mm) surface mount package defines the physical footprint. Substitute parts must accommodate the same or compatible package dimensions to ensure PCB layout compatibility.

Supply Voltage: The 5V supply requirement is a fundamental electrical constraint. Substitute components must operate within this voltage specification.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for modern component selection. Substitute parts must meet or exceed these compliance standards.

Product Status and Availability: Given the obsolete status of the original part, substitute components should preferably be active products with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The PM8563B-F3EI from Microchip Technology represents an active substitute option for the obsolete PCI9052 G. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying modern regulatory requirements. The PM8563B-F3EI operates as a Fanout PCIe Switch Interface within the Switchtec series, providing active product status with confirmed inventory availability.

The transition from PCI to PCI Express interface represents a protocol evolution. The PM8563B-F3EI is classified as a module package rather than a discrete 160-QFP, which may require PCB layout and mechanical design modifications. The MSL rating difference (3 versus 4) reflects different moisture sensitivity profiles and handling requirements during assembly.

Selection of the PM8563B-F3EI should be based on system architecture compatibility with PCI Express protocols and physical space availability for module-based packaging.

Frequently Asked Questions (FAQ)

Q: Can the PM8563B-F3EI directly replace the PCI9052 G without PCB modifications?

A: Direct pin-for-pin replacement is not possible. The PM8563B-F3EI uses module packaging while the PCI9052 G uses 160-QFP discrete packaging. PCB layout and mechanical design modifications are required.

Q: What is the primary functional difference between these components?

A: The PCI9052 G operates on PCI protocol, while the PM8563B-F3EI functions as a PCI Express fanout switch. These represent different interface generations and architectural approaches.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the PCI9052 G and PM8563B-F3EI maintain ROHS3 compliance and REACH unaffected status.

Q: What does the MSL rating difference indicate?

A: The PCI9052 G has MSL 3 (168 hours), while the PM8563B-F3EI has MSL 4 (72 hours). This indicates different moisture absorption characteristics and handling requirements during manufacturing and storage.

Q: Is the PM8563B-F3EI currently available?

A: Yes. The PM8563B-F3EI is classified as an active product with confirmed inventory availability, unlike the obsolete PCI9052 G.
