MCP47FVB22A3-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FVB22A3-E/ST is a 12-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring dual voltage output channels. This surface-mount component operates across a wide supply voltage range and features I2C interface compatibility. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specification, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP47FVB22A3-E/ST are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 12-bit conversion
• Channel count: 2 independent D/A converters
• Output configuration: Voltage-buffered topology
• Interface protocol: I2C digital communication
• Supply voltage range: 2.7V to 5.5V (both analog and digital rails)
• Accuracy specifications: INL/DNL performance (±1.5 LSB / ±0.2 LSB)
• Conversion architecture: R-2R ladder network
• Temperature operating range: -40°C to 125°C
• Physical package: 8-TSSOP form factor with 4.40mm width
• Surface-mount compatibility and RoHS3 compliance

The identified substitutes (MCP47FEB22A0-E/ST and MCP47FEB22A1-E/ST) maintain complete parametric alignment across all these criteria, differing only in internal device revision levels that do not affect functional performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MCP47FVB22A3-E/ST, MCP47FEB22A0-E/ST, and MCP47FEB22A1-E/ST—maintain active production status with identical compliance certifications. Each part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on availability and supply chain considerations, as all three are functionally equivalent for circuit design purposes. The differences in part number suffixes (A3, A0, A1) represent internal device revisions that do not alter electrical performance, pin configuration, or package specifications.

Frequently Asked Questions (FAQ)
