Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3EQX8908ZFEX is determined by strict equivalence across the following critical parameters:

• Manufacturer & Base Product Number: Same manufacturer (Diodes Incorporated) and identical base product number (PI3EQX8908)
• Functional Specifications: 8-channel configuration, 8Gbps data rate, input equalization and output de-emphasis signal conditioning
• Electrical Specifications: 3V to 3.6V supply voltage range
• Physical Package: 54-WFQFN Exposed Pad (54-TQFN 10x5.5mm form factor)
• Compliance & Certifications: ROHS3 Compliant, REACH Unaffected, MSL 1

The PI3EQX8908AZFEX qualifies as a direct substitute based on identical electrical, functional, and mechanical specifications. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison
