MCP47FVB02A2-E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FVB02A2-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 supplies, making it suitable for battery-powered and standard logic-level systems. The device features I2C interface communication, external/internal/supply reference options, and buffered voltage outputs with R-2R architecture. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across all critical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP47FVB02A2-E/ST is determined by strict equivalence across the following critical parameters:

• Resolution & Channel Count: 8-bit resolution with 2 D/A converters
• Interface Protocol: I2C communication standard
• Output Configuration: Buffered voltage output with no differential output requirement
• Supply Voltage Compatibility: 2.7V to 5.5V range for both analog and digital supplies
• Accuracy Specifications: INL/DNL values of ±0.1 and ±0.0125 LSB
• Settling Performance: 6µs typical settling time
• Package Specification: 8-TSSOP surface mount package with 0.173" width (4.40mm)
• Reference Architecture: Support for external, internal, and supply reference types
• Temperature Range: -40°C to 125°C operating window

The substitute part MCP47FEB02A0-E/ST meets all these criteria, differing only in internal die revision and manufacturing date code, which do not affect functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP47FVB02A2-E/ST and MCP47FEB02A0-E/ST are active products from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain considerations rather than technical performance differences.

The MCP47FEB02A0-E/ST offers higher inventory availability (1536 pcs vs. 808 pcs), making it the preferred choice for applications where supply continuity is a priority. Both devices maintain full compliance with ROHS3 and REACH regulations, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

For applications requiring the 8-bit dual DAC functionality with I2C interface in the 8-TSSOP package, either part number provides equivalent performance across all specified electrical parameters and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can MCP47FEB02A0-E/ST be used as a direct replacement for MCP47FVB02A2-E/ST?

A: Yes. Both parts are functionally equivalent across all electrical specifications, including resolution, settling time, supply voltage range, accuracy (INL/DNL), and I2C interface protocol. The package, pinout, and mounting type are identical.

Q: Are there any differences in the reference voltage options between these parts?

A: No. Both parts support identical reference type options: external, internal, and supply references. The reference architecture and performance are equivalent.

Q: What is the significance of the different part number suffixes (VB vs. EB)?

A: The suffix indicates internal die revision or manufacturing date code. These differences do not affect functional performance, electrical characteristics, or compatibility. Both parts meet the same specification requirements.

Q: Is the 8-TSSOP package compatible with standard PCB assembly equipment?

A: Yes. The 8-TSSOP package is a standard surface mount package with 0.173" width (4.40mm). Both parts use identical package specifications and are compatible with conventional SMT assembly processes.

Q: Do both parts require the same PCB layout and decoupling considerations?

A: Yes. Since the electrical specifications, supply voltage requirements (2.7V to 5.5V), and package are identical, the PCB layout, decoupling capacitor values, and signal routing requirements are the same for both parts.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL rating of 1 (Unlimited), meaning they have no moisture sensitivity constraints. Standard storage and handling procedures are sufficient without special desiccant packaging requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MCP47FVB02A2-E/ST and MCP47FEB02A0-E/ST are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for industrial and commercial applications.
