MCP47FVB01A3-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FVB01A3-E/ST is an 8-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring voltage output conversion. This active product operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains, with I2C interface compatibility and external, internal, or supply-based reference options. The component is housed in an 8-TSSOP surface mount package and is ROHS3 compliant with unlimited moisture sensitivity rating. Finding equivalent substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility needs while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The MCP47FVB01A3-E/ST has one parametric equivalent substitute: MCP47FVB01A0-E/ST. This substitution is valid based on strict parameter matching across all critical electrical and mechanical specifications. Both parts share identical core parameters that define functional compatibility:

• 8-bit resolution with single D/A converter
• Buffered voltage output with I2C interface
• Identical supply voltage ranges (2.7V ~ 5.5V for both analog and digital)
• Matching settling time of 6µs (Typ)
• Identical INL/DNL specifications (±0.1, ±0.0125 LSB)
• R-2R architecture
• Identical operating temperature range (-40°C ~ 125°C)
• Same 8-TSSOP package with 0.173" width (4.40mm)
• Surface mount configuration
• Matching compliance certifications (ROHS3, REACH Unaffected)

The substitution is based on parametric equivalence within the MCP47FVB01 base product family, where both variants maintain identical functional and mechanical characteristics.
