MCP47CMB28-E/ML Equivalent & Substitute Parts

Part Overview

The MCP47CMB28-E/ML is a 12-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring multiple voltage output channels. This device integrates eight independent DAC channels in a compact 20-QFN surface-mount package with an exposed pad. The part is currently in active production status with 985 units available in inventory.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative part numbers within the same product family. Identifying suitable alternatives ensures design flexibility, supply chain continuity, and cost optimization without compromising system performance.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP47CMB28-E/ML is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 12-bit resolution with 8 independent DAC channels
• Output Configuration: Voltage-buffered output topology
• Communication Protocol: I2C digital interface
• Supply Voltage Compatibility: Dual supply rails (analog and digital) operating within 1.8V to 5.5V range
• Accuracy Specifications: INL/DNL performance of ±1 LSB maximum
• Thermal Performance: Operating temperature range of -40°C to 125°C
• Physical Form Factor: 20-QFN (4x4) surface-mount package with exposed pad
• Regulatory Compliance: ROHS3 compliance and MSL 3 rating

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The MCP47CMB28-E/ML and MCP47CVB28-E/ML share identical electrical specifications and mechanical compatibility, differing only in internal temperature grade binning or manufacturing lot designation.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP47CMB28-E/ML and MCP47CVB28-E/ML are active production parts from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation.

The MCP47CMB28-E/ML is suitable for applications requiring immediate availability with 985 units in stock. The MCP47CVB28-E/ML provides an alternative with higher inventory levels (1085 units), supporting larger production volumes or extended procurement timelines.

Both parts are qualified for industrial and commercial temperature ranges (-40°C to 125°C) and maintain identical performance characteristics across all specified electrical parameters. PCB layout, firmware integration, and system-level testing require no modification when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are MCP47CMB28-E/ML and MCP47CVB28-E/ML electrically interchangeable?
