MCP47FVB12A2-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FVB12A2-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 device is housed in an 8-TSSOP surface mount package with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters that ensure direct functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP47FVB12A2-E/ST are qualified based on the following critical parameters that determine functional equivalence:

Resolution and Channel Count: All substitute parts maintain 10-bit resolution with dual D/A converters, ensuring identical digital conversion capability and output channel configuration.

Electrical Specifications: Substitute parts match the settling time (6µs typical), INL/DNL performance (±0.4, ±0.05 LSB), and R-2R architecture, guaranteeing equivalent analog performance characteristics.

Supply Voltage Range: All parts operate across 2.7V to 5.5V for both analog and digital supplies, enabling direct replacement in existing power distribution designs.

Interface and Reference: I2C data interface and support for external, internal, and supply-based reference types are maintained across all substitute parts.

Package and Mounting: All parts use the 8-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm width), allowing direct PCB footprint compatibility.

Compliance and Environmental: All parts maintain ROHS3 compliance, unlimited MSL rating, and active product status, ensuring regulatory and supply chain consistency.

Parameter Comparison

Engineering Selection Recommendations

All four parts—MCP47FVB12A2-E/ST, MCP47FEB12A0-E/ST, MCP47FEB12A2-E/ST, and MCP47FVB12A0-E/ST—are active products from Microchip Technology with identical electrical and mechanical specifications. Selection among these parts is based on availability and supply chain considerations rather than functional differences. All parts maintain ROHS3 compliance and unlimited MSL rating, ensuring regulatory consistency and environmental robustness across applications. The parts differ only in base product number designation (MCP47FVB12 versus MCP47FEB12) and temperature grade suffix (A0 versus A2), which do not affect core operational parameters within the specified -40°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can MCP47FEB12A0-E/ST, MCP47FEB12A2-E/ST, and MCP47FVB12A0-E/ST be used interchangeably with MCP47FVB12A2-E/ST?

A: Yes. All four parts share identical electrical specifications, including 10-bit resolution, dual D/A converters, 6µs settling time, I2C interface, and R-2R architecture. They are housed in the same 8-TSSOP package with matching pin configurations and supply voltage requirements (2.7V to 5.5V). Direct substitution is supported without circuit modification.

Q: What is the difference between the MCP47FVB12 and MCP47FEB12 base product numbers?

A: The base product number designation does not affect the electrical or mechanical parameters provided in this specification. Both variants maintain identical performance characteristics, package dimensions, and operational ranges. Selection between them is determined by availability and supply chain factors.

Q: Are there any temperature grade differences between the A0 and A2 suffixes?

A: Both A0 and A2 variants operate across the full -40°C to 125°C temperature range. The suffix designation does not alter the operating temperature specification or performance characteristics within this range.

Q: Is the 8-TSSOP package footprint identical across all substitute parts?

A: Yes. All parts use the 8-TSSOP surface mount package with dimensions of 0.173" × 4.40mm width. PCB footprints and land patterns are directly compatible without modification.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All parts are ROHS3 compliant with unlimited MSL rating (1), REACH unaffected status, and EAR99 ECCN classification. Regulatory and environmental compliance is consistent across all substitute options.

Q: What reference voltage options are available across all substitute parts?

A: All parts support external, internal, and supply-based reference types, providing identical flexibility in reference voltage configuration for different application requirements.
