Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3PCIE3413ZHEX is determined by strict alignment of the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 42-TQFN (9x4.6) surface mount package with 42-VFQFN Exposed Pad configuration to ensure PCB layout and thermal management compatibility.
• Electrical Supply: Voltage supply range must match 3V ~ 3.6V single supply specification.
• Operating Temperature Range: Must support -40°C ~ 85°C operating conditions.
• Series Alignment: Both parts must belong to the PCI Express® (PCIe) series.
• Functional Classification: Both parts must function as multiplexer/demultiplexer interface circuits with 3:1 configuration.
• Bi-Directional Capability: Both parts must support bi-directional signal transmission.
• Compliance Standards: RoHS3 compliance, MSL Level 1, and REACH unaffected status must be maintained.

The PI3PCIE3413AZHEX qualifies as a direct substitute based on these parameters, despite differences in channel count and bandwidth specifications, as these variations do not violate the core substitution criteria for this product category.

Parameter Comparison

Engineering Selection Recommendations

The PI3PCIE3413AZHEX is qualified as a direct substitute for the obsolete PI3PCIE3413ZHEX based on matching package geometry, electrical supply specifications, operating temperature range, and regulatory compliance status. Both components maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected designation, ensuring regulatory continuity in applications requiring these certifications.

The substitute part carries Active product status, providing long-term availability and supply chain stability compared to the obsolete main part. Both components share identical base product number designation (PI3PCIE3413), confirming manufacturer-level compatibility within the PCI Express® Switch IC product line.

Frequently Asked Questions (FAQ)

Q: Can PI3PCIE3413AZHEX directly replace PI3PCIE3413ZHEX in existing designs?

A: Yes. Both parts share identical package geometry (42-TQFN 9x4.6), electrical supply requirements (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and mounting type (Surface Mount). PCB layout and thermal design compatibility are maintained.

Q: What are the differences between these two parts?

A: The substitute part (PI3PCIE3413AZHEX) provides 4 channels versus 1 channel in the main part, and operates at 6.8GHz bandwidth versus 8.3GHz. The substitute carries Active product status, ensuring ongoing availability.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, MSL Level 1 rating, REACH unaffected status, EAR99 export classification, and HTSUS code (8542.39.0001).

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part's Active status provides a path forward for applications requiring this component category.

Q: Does the package expose pad configuration differ between parts?

A: No. Both parts use 42-VFQFN Exposed Pad configuration, maintaining identical thermal and electrical interface characteristics.
