Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB2250-NU-05 is determined by strict alignment across the following critical parameters:

• Base Product Number: Must be USB2250 to ensure functional equivalence within the same controller family
• Protocol & Standards: USB 2.0 protocol compliance is mandatory
• Electrical Specifications: Voltage supply range (3V ~ 3.6V) and supply current (135mA) must match exactly
• Operating Temperature Range: 0°C ~ 70°C operational window must be maintained
• Package Footprint: 128-TQFP package with 128-VTQFP (14x14) supplier designation ensures mechanical and electrical pin compatibility
• Compliance Standards: RoHS3 compliance and REACH status must be equivalent or superior

The USB2250-NU-06 qualifies as a direct substitute based on complete alignment across all specified parameters.
