PI3PCIE3413ZHE Equivalent & Substitute Parts

Part Overview

The PI3PCIE3413ZHE is a PCI Express® Switch IC manufactured by Diodes Incorporated, designed for high-speed signal routing in PCIe applications. This component features a 3:1 multiplexer/demultiplexer configuration with 1 channel in a 42-TQFN (9x4.6) surface mount package. The device operates at 3V to 3.6V supply voltage with an 8.3GHz -3dB bandwidth and bi-directional switching capability.

The PI3PCIE3413ZHE is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage, package form factor, bandwidth performance, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3PCIE3413ZHE is determined by strict alignment with the following critical parameters:

Mandatory Compatibility Criteria:

• Supply voltage range: 3V ~ 3.6V (single supply)
• Package form factor: 42-TQFN (9x4.6) with exposed pad
• Mounting type: Surface mount
• Operating temperature range: -40°C ~ 85°C
• Series classification: PCI Express® (PCIe)
• Multiplexer/Demultiplexer circuit type: 3:1
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Performance Parameters:

• -3dB Bandwidth: Must support minimum 6.8GHz or higher
• Features: Bi-directional switching capability
• Moisture Sensitivity Level: MSL 1 or equivalent

The PI3PCIE3413AZHEX qualifies as a direct substitute based on identical supply voltage, package dimensions, mounting type, operating temperature range, series classification, and regulatory compliance. Both components share the same base product number (PI3PCIE3413) and are manufactured by Diodes Incorporated.

Parameter Comparison

Engineering Selection Recommendations

The PI3PCIE3413AZHEX is a qualified substitute for the obsolete PI3PCIE3413ZHE. Both components share identical electrical supply requirements, package dimensions, thermal operating range, and regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The PI3PCIE3413AZHEX maintains active product status with Diodes Incorporated, ensuring continued availability and manufacturing support. The substitute part provides 4 channels compared to the main part's 1 channel configuration, offering expanded functionality within the same physical package footprint. The -3dB bandwidth of 6.8GHz on the substitute part remains within acceptable performance parameters for PCIe switching applications, though 0.5GHz lower than the original specification.

Both components are classified as MSL 1 (Unlimited moisture sensitivity level), indicating no special moisture handling requirements during storage or assembly. The identical package form factor (42-TQFN with 9x4.6mm dimensions and exposed pad) ensures direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the PI3PCIE3413AZHEX be used as a direct replacement for the PI3PCIE3413ZHE?

A: Yes. Both components share identical supply voltage (3V ~ 3.6V), package dimensions (42-TQFN 9x4.6mm), mounting type (surface mount), operating temperature range (-40°C ~ 85°C), and regulatory compliance status. The substitute part is electrically and mechanically compatible.

Q: What is the difference in channel count between these parts?

A: The PI3PCIE3413ZHE provides 1 channel, while the PI3PCIE3413AZHEX provides 4 channels. Both use a 3:1 multiplexer/demultiplexer circuit topology. The increased channel count in the substitute part does not affect physical compatibility or electrical interface requirements.

Q: How does the bandwidth difference affect substitution?

A: The main part specifies 8.3GHz -3dB bandwidth, while the substitute specifies 6.8GHz. The substitute part's bandwidth remains suitable for PCI Express® applications. The 0.5GHz difference reflects manufacturing variations within the same product family and does not indicate functional incompatibility.

Q: Are there any moisture sensitivity or handling differences?

A: No. Both parts are classified as MSL 1 (Unlimited), meaning neither component requires special moisture control during storage, handling, or assembly. Standard ESD precautions apply to both.

Q: What is the product status difference, and does it matter?

A: The PI3PCIE3413ZHE is obsolete, while the PI3PCIE3413AZHEX is active. Active status means the substitute part is currently manufactured and supported by Diodes Incorporated, ensuring long-term availability and supply chain reliability.

Q: Are the regulatory certifications identical?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both share the same HTSUS code (8542.39.0001). No regulatory re-qualification is required for substitution.

Q: Can I use the PI3PCIE3413AZHEX in existing PCB designs without modification?

A: Yes. The identical 42-TQFN (9x4.6mm) package with exposed pad ensures direct footprint compatibility. No PCB layout changes are required for mechanical or electrical interface purposes.
