MCP47CMB02-E/UN Equivalent & Substitute Parts

Part Overview

The MCP47CMB02-E/UN is an 8-bit digital-to-analog converter (DAC) with dual output channels, manufactured by Microchip Technology. This active product features I2C interface control, buffered voltage output, and operates across a wide supply voltage range of 1.8V to 5.5V for both analog and digital domains. The component is housed in a 10-MSOP surface mount package and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The MCP47CVB02-E/UN qualifies as a parametric equivalent to the MCP47CMB02-E/UN based on strict alignment of the following critical parameters:

• 8-bit resolution with dual D/A converter channels
• Identical I2C digital interface
• Buffered voltage output configuration
• Matching supply voltage ranges (1.8V ~ 5.5V for both analog and digital)
• Identical settling time specification (16µs typical)
• Equivalent INL/DNL performance (±0.1 LSB)
• Identical operating temperature range (-40°C ~ 125°C)
• Identical package and pinout (10-MSOP surface mount)
• Same base product architecture (Current Source)

Both parts share the same functional classification, electrical performance envelope, and mechanical compatibility, enabling direct substitution in circuit designs without modification to PCB layout or firmware control sequences.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP47CMB02-E/UN and MCP47CVB02-E/UN are active products from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on moisture sensitivity requirements for storage and handling conditions. The MCP47CMB02-E/UN carries MSL 2 rating (1 Year shelf life), while the MCP47CVB02-E/UN carries MSL 3 rating (168 Hours shelf life). For applications requiring extended storage without baking or in high-humidity environments, the MCP47CMB02-E/UN is preferred. For applications with controlled storage conditions and shorter lead times, the MCP47CVB02-E/UN provides equivalent electrical and mechanical performance. Both parts are suitable for industrial temperature range applications (-40°C to 125°C) and support identical I2C control protocols without firmware modification.

Frequently Asked Questions (FAQ)

Q: Can MCP47CVB02-E/UN replace MCP47CMB02-E/UN in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including resolution, converter count, interface protocol, output type, supply voltage ranges, settling time, and package configuration. Direct substitution is possible without PCB redesign or firmware changes.

Q: What is the difference between these two parts?

A: The primary difference is moisture sensitivity level (MSL). MCP47CMB02-E/UN is MSL 2 with 1-year shelf life, while MCP47CVB02-E/UN is MSL 3 with 168-hour shelf life. All electrical specifications and package dimensions are identical.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the full industrial temperature range of -40°C to 125°C with identical performance specifications.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the identical 10-MSOP surface mount package with 0.118" width (3.00mm). PCB layouts are fully compatible.

Q: Which part should I select for high-humidity storage environments?

A: The MCP47CMB02-E/UN with MSL 2 rating is recommended for extended storage in high-humidity conditions without baking. The MCP47CVB02-E/UN with MSL 3 rating requires more frequent baking cycles if stored beyond 168 hours in humid conditions.

Q: Are both parts ROHS3 compliant?

A: Yes. Both MCP47CMB02-E/UN and MCP47CVB02-E/UN are ROHS3 compliant and REACH unaffected.
