Substitute Part Grouping Explanation

Substitute parts for the MCP47FVB21A2-E/ST are determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit DAC architecture
• Channel Count: Single D/A converter
• Output Configuration: Voltage output with buffering
• Communication Protocol: I2C interface
• Supply Voltage Range: 2.7V to 5.5V (both analog and digital)
• Linearity Specifications: INL/DNL of ±1.5 LSB and ±0.2 LSB
• Settling Performance: 6µs typical settling time
• Package Format: 8-TSSOP surface mount
• Thermal Range: -40°C to 125°C operating temperature
• Compliance: ROHS3 and REACH compliance status

The MCP47FVB21A0-E/ST meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (MCP47FVB21) and differ only in internal configuration codes that do not affect functional performance in standard applications.
