PI7C9X2G808PRNJEX Equivalent & Substitute Parts

Part Overview

The PI7C9X2G808PRNJEX is an 8-port, 8-lane packet switch interface IC manufactured by Diodes Incorporated. This GreenPacket™ series component operates as a specialized interface device in the 196-PBGA package format. The part is currently in active production status with 1,172 units available in inventory. Finding equivalent substitute parts may be necessary due to supply constraints, lead time requirements, or design flexibility needs in PCI Express-based packet switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI7C9X2G808PRNJEX are qualified based on the following critical parameters:

• Interface Type: PCI Express compatibility
• Functional Category: Fanout PCIe Switch Interface
• Mounting Type: Surface Mount
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status
• Product Status: Active production status

The two qualified substitutes (PM8534B-FEI and PM8562B-F3EI) are both manufactured by Microchip Technology under the Switchtec series. Both parts maintain PCI Express interface compatibility and active product status. While package formats differ from the original 196-PBGA specification, both substitutes are designed for fanout PCIe switch applications and meet the same regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both PM8534B-FEI and PM8562B-F3EI are active production parts that maintain full ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original PI7C9X2G808PRNJEX. All three parts are surface mount interface devices designed for PCI Express applications.

The primary distinction between the original part and substitutes is the package format transition from 196-PBGA to Module configuration. This change requires PCB layout and mechanical assembly evaluation during design integration. Both Microchip substitutes demonstrate higher inventory availability (2,100 and 2,200 units respectively) compared to the original part (1,172 units).

The MSL rating difference (original MSL 3 versus substitute MSL 4) reflects different moisture sensitivity specifications and should be considered in storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can PM8534B-FEI and PM8562B-F3EI be used interchangeably with PI7C9X2G808PRNJEX?

A: Both parts share PCI Express interface compatibility and active product status. However, the package format change from 196-PBGA (15x15) to Module configuration requires PCB redesign and mechanical assembly modifications. Electrical functionality for fanout PCIe switch applications is maintained across all three parts.

Q: What is the impact of the MSL rating difference?

A: The original part carries MSL 3 (168 hours), while both substitutes carry MSL 4 (72 hours). MSL 4 indicates a shorter allowable time at elevated temperature and humidity before soldering. Storage and handling procedures must account for the more stringent moisture sensitivity of the substitute parts.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. PI7C9X2G808PRNJEX, PM8534B-FEI, and PM8562B-F3EI are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by PCI Express interface compatibility, surface mount mounting type, active product status, and matching regulatory compliance (ROHS3 and REACH). Package format differences require design consideration but do not prevent functional substitution in fanout PCIe switch applications.

Q: Which substitute part should be selected?

A: Selection between PM8534B-FEI and PM8562B-F3EI depends on specific application requirements and design constraints. Both parts are functionally equivalent for PCI Express packet switching applications and maintain identical compliance certifications. Inventory availability is comparable for both options (2,100 and 2,200 units respectively).
