Substitute Part Grouping Explanation

The MCP47CMB21-E/MG has one identified parametric equivalent: MCP47CVB21-E/MG. This substitution is valid based on strict parameter matching across all critical electrical and mechanical specifications. Both parts maintain identical performance characteristics in the following key areas:

• 12-bit resolution with single D/A converter channel
• Buffered voltage output configuration
• I2C digital interface protocol
• Dual external and internal reference capability
• Identical supply voltage ranges (1.8V to 5.5V for both analog and digital)
• Matching linearity specifications (±1 LSB INL/DNL)
• Identical settling time of 16µs typical
• Full operating temperature range from -40°C to 125°C
• Identical 16-VFQFN exposed pad package with surface mount configuration
• Matching RoHS3 compliance and MSL rating

The substitution is based on parametric equivalence within the Microchip MCP47 DAC family, where both parts share the same functional architecture and electrical performance envelope.
