MCP47FEB12A3-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FEB12A3-E/ST is a 10-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, with I2C interface control and external, internal, or supply-based reference options. The component is packaged in an 8-TSSOP surface-mount configuration with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the product family, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP47FEB12A3-E/ST is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 10-bit resolution with dual D/A converters
• Interface Protocol: I2C communication standard
• Output Configuration: Buffered voltage output with no differential output requirement
• Supply Voltage Range: 2.7V to 5.5V for both analog and digital supplies
• Accuracy Specifications: INL/DNL performance of ±0.4 and ±0.05 LSB
• Thermal Performance: 6µs typical settling time and -40°C to 125°C operating range
• Physical Form Factor: 8-TSSOP package with identical 0.173" width and 4.40mm dimensions
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

All substitute parts maintain identical electrical and mechanical specifications, differing only in internal reference architecture variants or speed grade designations that do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with Microchip Technology, ensuring continued availability and technical support. Each part carries ROHS3 compliance and REACH unaffected certification, meeting regulatory requirements for industrial and commercial applications.

Selection between MCP47FEB12A3-E/ST, MCP47FEB12A0-E/ST, MCP47FEB12A2-E/ST, and MCP47FVB12A0-E/ST is based on inventory availability and internal reference architecture variants. The MCP47FVB12A0-E/ST variant uses a different base product designation (MCP47FVB12 versus MCP47FEB12) but maintains identical electrical performance and package specifications. All parts are suitable for direct PCB substitution without circuit redesign.
