Substitute Part Grouping Explanation

Substitute parts for the USB7252CT-I/KDX are identified based on strict parametric alignment across the following criteria:

Electrical Compatibility: Supply voltage range (1.09V ~ 1.21V, 3V ~ 3.6V) and operating temperature range (-40°C ~ 85°C) must match exactly.

Package Compatibility: Physical package type must be 100-VFQFN Exposed Pad with 12x12mm dimensions to ensure PCB footprint compatibility.

Interface Protocol Support: All auxiliary interfaces (GPIO, I2C, I2S, SPI, SMBus) and primary USB interface must be present.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status must be maintained.

Manufacturer Consistency: Parts must originate from Microchip Technology to ensure design validation and support continuity.

USB Standard Compatibility: USB 2.0 support is mandatory; USB 3.x generation (3.1 or 3.2) variations are acceptable when all other parameters align, as these represent protocol evolution within the same functional category.
