Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3PCIE3442ZLEX is determined by strict alignment of the following critical parameters:

• Package / Case: 40-WFQFN Exposed Pad (40-TQFN 3x6)
• Number of Channels: 8
• Multiplexer/Demultiplexer Circuit: 1:1
• Features: Bi-Directional
• Voltage - Supply, Single (V+): 3V ~ 3.6V
• Series: PCI Express® (PCIe)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The PI3PCIE3442AZLEX qualifies as a direct substitute based on full alignment with these parameters. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the substitute part is active, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The PI3PCIE3442AZLEX is a direct functional and mechanical equivalent to the PI3PCIE3442ZLEX. Both components are manufactured by Diodes Incorporated and share identical electrical specifications, package geometry, and regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99 classification).

The primary advantage of selecting the PI3PCIE3442AZLEX is its active product status, which ensures ongoing availability and supply chain support. The obsolete status of the PI3PCIE3442ZLEX presents supply constraints and potential discontinuation risks.

Both parts meet identical compliance requirements and are suitable for direct substitution in PCIe interface applications requiring 8-channel 1:1 multiplexing with bi-directional signal routing at 3V to 3.6V supply voltage.

Frequently Asked Questions (FAQ)

Q: Can the PI3PCIE3442AZLEX be used as a direct replacement for the PI3PCIE3442ZLEX?
