Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP47FVB28T-E/MQ are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 12-bit conversion capability
• Channel Count: 8 independent D/A converters
• Output Configuration: Voltage output with both buffered and unbuffered modes
• Communication Protocol: I2C data interface
• Supply Voltage Range: 2.7V to 5.5V for both analog and digital supplies
• Settling Time: 7.8µs typical response time
• Linearity Specifications: ±1.5LSB INL and ±0.2LSB DNL
• Temperature Range: -40°C to 125°C operating window
• Package Format: 20-VQFN (5x5) with exposed pad
• Surface Mount Compatibility: Standard PCB assembly processes
• Compliance Standards: RoHS3 and REACH requirements

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in base product number (suffix changes) that do not alter electrical performance or package specifications are acceptable for substitution purposes.
