MCP47FEB02A2-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FEB02A2-E/ST is an 8-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring dual voltage output channels. This active product operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains, making it suitable for battery-powered and standard logic-level systems. The device communicates via I2C interface and features buffered voltage outputs with external, internal, or supply-based reference options. Substitute parts may be required due to inventory constraints, regional availability, or procurement lead time considerations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MCP47FEB02A2-E/ST is based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitute part MCP47FEB02A0-E/ST shares identical characteristics in the following key parameters that determine functional interchangeability:

• 8-bit resolution with dual D/A converter channels
• 6µs typical settling time
• Buffered voltage output configuration
• I2C serial communication interface
• Flexible reference voltage options (external, internal, supply)
• Identical supply voltage ranges (2.7V ~ 5.5V for both analog and digital)
• Matching INL/DNL specifications (±0.1, ±0.0125 LSB)
• R-2R converter architecture
• Full operating temperature range (-40°C ~ 125°C)
• 8-TSSOP surface mount package with identical physical dimensions
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

Both the MCP47FEB02A2-E/ST and MCP47FEB02A0-E/ST are active products from Microchip Technology with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The MCP47FEB02A0-E/ST offers higher current inventory availability (1536 pcs versus 1085 pcs), which may provide advantages for procurement timelines and supply chain continuity. Selection between these parts should be based on inventory availability and delivery requirements, as all electrical performance, thermal characteristics, and mechanical specifications are identical. Both devices are suitable for direct substitution in existing designs without circuit modification or re-qualification.
