Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI2PCIE2422ZHEX is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 42-TQFN (9x4.6) package with exposed pad configuration to ensure PCB layout compatibility and reflow soldering process alignment.

Interface Standard: Both components must support PCI Express interface functionality to maintain system-level signal integrity and protocol compliance.

Mounting Technology: Surface mount technology is required for both parts to match existing assembly processes.

Electrical Characteristics: The substitute must support PCI Express signal switching with comparable bandwidth and on-state resistance specifications to ensure signal fidelity in high-speed applications.

Regulatory Compliance: Both components must maintain ROHS3 compliance and MSL Level 1 rating to meet manufacturing and environmental standards.

The PI3PCIE3442AZHEX qualifies as a manufacturer-recommended substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The PI3PCIE3442AZHEX is the manufacturer-recommended substitute for the obsolete PI2PCIE2422ZHEX. Both components share identical package geometry (42-TQFN 9x4.6), mounting technology, and regulatory compliance status (ROHS3, MSL Level 1, REACH Unaffected, EAR99 classification).

The substitute part maintains active product status with Diodes Incorporated, ensuring long-term availability and supply chain stability. Both components are classified under the same HTSUS code (8542.39.0001), confirming functional equivalence in the interface IC category.

The identical package footprint and exposed pad configuration enable direct PCB layout reuse without redesign. Surface mount assembly processes remain unchanged between the two components.

Frequently Asked Questions (FAQ)

Q: Can the PI3PCIE3442AZHEX be used as a direct replacement for the PI2PCIE2422ZHEX?

A: Yes. Both components use the identical 42-TQFN (9x4.6) package with exposed pad configuration, identical mounting technology, and equivalent regulatory compliance. The substitute is manufacturer-recommended by Diodes Incorporated.

Q: Are there PCB layout changes required when switching to the PI3PCIE3442AZHEX?

A: No. The identical package footprint and pin configuration eliminate the need for PCB redesign. Existing assembly processes and reflow profiles remain applicable.

Q: What is the difference in supply voltage between these parts?

A: The PI2PCIE2422ZHEX operates at 1.5V ~ 1.8V single supply. The PI3PCIE3442AZHEX operates at 3V ~ 3.6V supply. Circuit design must account for this voltage difference during implementation.

Q: Are both parts compliant with current environmental and trade regulations?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain MSL Level 1 (unlimited moisture sensitivity) rating.

Q: Why is the PI2PCIE2422ZHEX marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The PI3PCIE3442AZHEX maintains active status, ensuring continued availability for new designs and production support.
