Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB7216T/KDX is determined by the following critical parameters:

• Package Compatibility: Identical 100-VFQFN Exposed Pad package (100-VQFN 12x12 footprint)
• Manufacturer Consistency: Same manufacturer (Microchip Technology) to ensure design validation and support continuity
• Interface Protocol: SPI interface capability required for host system integration
• USB Standards Support: Minimum USB 3.0 compliance; USB 3.1 support acceptable
• Compliance Certifications: ROHS3 compliance and REACH unaffected status maintained
• Moisture Sensitivity: MSL 3 (168 Hours) classification for handling and storage requirements

The USB7216CT/KDX qualifies as a direct substitute based on these parameters. It maintains identical packaging, manufacturer origin, and compliance certifications while offering enhanced interface capabilities and active product status.
