MCP48CVB24T-E/ML Equivalent & Substitute Parts

Part Overview

The MCP48CVB24T-E/ML is a 12-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications. This integrated circuit features four independent D/A converters with voltage-buffered outputs, operating across a wide supply voltage range of 1.8V to 5.5V. The device is housed in a 20-QFN (4x4) surface-mount package with an exposed pad and is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the product line, ensuring functional interchangeability within specified design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP48CVB24T-E/ML are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

• 12-bit resolution with 4 independent D/A converters
• 16µs typical settling time
• Voltage-buffered output configuration
• SPI serial data interface
• External, internal, and supply reference type support
• 1.8V to 5.5V dual supply voltage range (both analog and digital)
• ±1 LSB maximum INL/DNL specification
• R-2R converter architecture
• -40°C to 125°C operating temperature range
• 20-QFN (4x4) surface-mount package with exposed pad
• ROHS3 compliance and REACH unaffected status

All substitute parts listed maintain identical electrical performance characteristics and physical packaging specifications, ensuring direct functional interchangeability in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—MCP48CVB24T-E/ML, MCP48CMB24T-E/ML, and MCP48CVB24-E/ML—are functionally equivalent and maintain active production status with Microchip Technology. Each part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on availability and packaging format requirements. The MCP48CMB24T-E/ML currently maintains the highest inventory level at 4,283 pieces, followed by MCP48CVB24-E/ML at 1,192 pieces, and MCP48CVB24T-E/ML at 830 pieces. All parts are supplied in tape and reel (TR) packaging suitable for automated assembly processes.

The identical electrical specifications across all three parts ensure that circuit designs developed for one part number will function identically when populated with any of the substitute parts, provided that the 20-QFN (4x4) surface-mount package and MSL 3 moisture sensitivity handling requirements are accommodated in manufacturing and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MCP48CMB24T-E/ML be used as a direct replacement for MCP48CVB24T-E/ML?

A: Yes. Both parts are 12-bit, 4-channel digital-to-analog converters with identical electrical specifications, including 16µs settling time, SPI interface, and 1.8V to 5.5V supply voltage range. They share the same 20-QFN (4x4) package and are both ROHS3 compliant.

Q: What is the difference between MCP48CVB24T-E/ML and MCP48CVB24-E/ML?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format designation within the part number structure. Both are supplied in tape and reel (TR) packaging and are suitable for identical applications.

Q: Are all three parts suitable for the same PCB layout and assembly process?

A: Yes. All three parts use the 20-QFN (4x4) surface-mount package with exposed pad and share identical pin configurations. PCB layouts and reflow profiles developed for one part are directly applicable to the others. All parts have MSL 3 moisture sensitivity rating with 168-hour floor life.

Q: Which part should be selected based on availability?

A: Selection should prioritize inventory availability for project timelines. MCP48CMB24T-E/ML offers the highest stock level, making it suitable for high-volume production runs. MCP48CVB24-E/ML and MCP48CVB24T-E/ML are available in lower quantities and may be selected based on specific supply chain or procurement requirements.

Q: Do these parts require different reference voltage configurations?

A: No. All three parts support identical reference type options: external, internal, and supply references. Circuit designs utilizing any reference configuration are directly transferable between parts.

Q: Are there any temperature or compliance differences between the substitute parts?

A: No. All parts operate across the identical -40°C to 125°C temperature range and maintain ROHS3 compliance and REACH unaffected status. Environmental and regulatory requirements are equivalent across all three parts.
