MCP48CMB28T-E/ML Equivalent & Substitute Parts

Part Overview

The MCP48CMB28T-E/ML is a 12-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring voltage output conversion. This device integrates eight DAC channels in a compact 20-QFN surface-mount package with an exposed pad. The part is currently in active production status with 1067 units available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the product line. Alternative part numbers may be necessary due to packaging format availability, inventory levels, or specific supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP48CMB28T-E/ML are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• 12-bit resolution
• 8 DAC channels
• Voltage-buffered output type
• SPI data interface
• 16µs typical settling time
• 1.8V to 5.5V analog and digital supply voltage range
• ±1 LSB maximum INL/DNL specification
• R-2R architecture
• -40°C to 125°C operating temperature range

Mechanical Parameters (Must Match):

• 20-QFN (4x4) package with exposed pad
• Surface-mount configuration
• ROHS3 compliance
• MSL 3 rating

Packaging Format Variation: The primary distinction among substitute parts is the packaging format: Tape & Reel (TR) versus Cut Tape (CT). Both formats contain identical die and electrical specifications but differ in supply presentation and handling methodology.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MCP48CMB28T-E/ML, MCP48CVB28-E/ML, and MCP48CVB28T-E/ML—are manufactured by Microchip Technology and maintain active product status. Each part carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

The MCP48CVB28T-E/ML offers the highest inventory availability at 4252 units and is supplied in Cut Tape format, suitable for automated pick-and-place assembly operations. The MCP48CVB28-E/ML and MCP48CMB28T-E/ML are both supplied in Tape & Reel format with comparable inventory levels (1002 and 1067 units respectively), appropriate for high-volume production environments.

Selection between these parts should be based on supply chain requirements, assembly methodology, and inventory availability rather than electrical performance, as all three devices are electrically and mechanically equivalent within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Are MCP48CMB28T-E/ML, MCP48CVB28-E/ML, and MCP48CVB28T-E/ML electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 12-bit resolution, 8 DAC channels, SPI interface, voltage-buffered output, and operating parameters. They are direct functional equivalents.

Q: What is the difference between Tape & Reel and Cut Tape packaging formats?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging supplies the same components on cut segments of carrier tape, suitable for smaller production runs or manual assembly processes. Both formats contain identical components.

Q: Can I substitute MCP48CVB28T-E/ML (Cut Tape) for MCP48CMB28T-E/ML (Tape & Reel) in production?

A: Substitution is possible if your assembly equipment supports Cut Tape format. The electrical and mechanical specifications are identical. Verify that your pick-and-place system is configured for the Cut Tape format before implementation.

Q: Are all three parts ROHS3 compliant?

A: Yes. MCP48CMB28T-E/ML, MCP48CVB28-E/ML, and MCP48CVB28T-E/ML all carry ROHS3 compliance certification and are REACH unaffected.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have an MSL rating of 3 with a floor life of 168 hours. This indicates standard moisture sensitivity requiring standard handling and storage procedures for surface-mount components.

Q: Which part should I select for immediate availability?

A: MCP48CVB28T-E/ML offers the highest inventory level at 4252 units. However, all three parts are in active production with available stock.

Q: Are there any differences in operating temperature range among these parts?

A: No. All three parts operate across the identical temperature range of -40°C to 125°C.
