Substitute Part Grouping Explanation

The PI3PCIE3442AZLEX qualifies as a direct substitute for the PI3PCIE3442ZLE based on the following critical parameters:

• Identical base product number (PI3PCIE3442)
• Matching package geometry: 40-WFQFN Exposed Pad (3x6mm)
• Identical electrical specifications: 8-channel PCIe switch, 6.5 GHz bandwidth, 3V ~ 3.6V supply voltage
• Equivalent operating temperature range: -40°C ~ 85°C
• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99
• Same moisture sensitivity level: MSL 1 (Unlimited)

The primary distinction is product status: PI3PCIE3442ZLE is obsolete, while PI3PCIE3442AZLEX is active. The substitute part is supplied in Tape & Reel packaging format, suitable for automated assembly processes.

Parameter Comparison
