MCP48FVB24-E/MQ Equivalent & Substitute Parts

Part Overview

The MCP48FVB24-E/MQ is a 12-bit digital-to-analog converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications. This device integrates four independent D/A converters in a 20-VQFN surface-mount package with an exposed pad. The part is active in production status and carries automotive-grade qualification under AEC-Q100 standards, making it suitable for demanding industrial and automotive environments.

Substitute parts are identified when equivalent electrical and mechanical specifications allow direct replacement in circuit designs. The MCP48FVB24-E/MQ has documented parametric equivalents that maintain core functionality while offering variations in converter count or reference architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP48FVB24-E/MQ is determined by the following core parameters:

Critical Matching Parameters:

• 12-bit resolution
• SPI data interface
• External reference type
• Voltage supply ranges: 2.7V ~ 5.5V (both analog and digital)
• INL/DNL specifications: ±0.4LSB, ±0.05LSB
• Operating temperature range: -40°C ~ 125°C
• 20-VQFN surface-mount package with exposed pad
• Automotive grade with AEC-Q100 qualification
• ROHS3 compliance and MSL 3 rating

Variable Parameters Allowing Substitution:

• Number of D/A converters (4 or 8 channels)
• Reference architecture (buffered or unbuffered output)

The MCP48FEB24-E/MQ and MCP48FEB28-E/MQ differ from the main part in reference buffer configuration (buffered versus unbuffered). The MCP48FVB28-E/MQ maintains the unbuffered architecture but provides eight converters instead of four. All three substitute parts maintain identical electrical performance, package form factor, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and carry identical automotive-grade qualification under AEC-Q100 standards. Each part is ROHS3 compliant and carries the same REACH unaffected status, ensuring regulatory compliance across applications.

Selection Criteria by Application:

For applications requiring four independent D/A converter channels with unbuffered voltage output, the MCP48FVB24-E/MQ is the primary selection. The MCP48FEB24-E/MQ provides an identical four-channel configuration and serves as a direct functional equivalent.

For applications requiring eight independent D/A converter channels within the same package footprint and electrical specification envelope, the MCP48FVB28-E/MQ is the appropriate selection. This part maintains all electrical performance characteristics while doubling the converter count.

The MCP48FEB28-E/MQ provides eight converter channels and is functionally equivalent to the MCP48FVB28-E/MQ, offering an alternative source option.

All parts operate within the same supply voltage ranges, temperature extremes, and settling time specifications. Selection between these parts depends solely on the required number of converter channels and circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the MCP48FVB24-E/MQ be replaced with the MCP48FEB24-E/MQ in existing designs?

A: Yes. Both parts share identical electrical specifications, package form factor, and compliance certifications. The parts are functionally interchangeable for four-channel DAC applications.

Q: What is the primary difference between the MCP48FVB24-E/MQ and MCP48FVB28-E/MQ?

A: The MCP48FVB28-E/MQ provides eight D/A converter channels compared to four channels in the MCP48FVB24-E/MQ. All other electrical and mechanical specifications remain identical. Both parts use the same 20-VQFN package.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed substitute parts carry automotive-grade designation and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: Do the substitute parts require different PCB layout considerations?

A: No. All substitute parts use the identical 20-VQFN surface-mount package with exposed pad. PCB footprints and layout requirements are identical across all parts.

Q: What is the significance of the MSL 3 rating?

A: MSL 3 indicates a moisture sensitivity level requiring storage at controlled humidity conditions for 168 hours maximum before reflow soldering. This specification applies to the MCP48FVB24-E/MQ, MCP48FEB24-E/MQ, and MCP48FVB28-E/MQ.

Q: Can I use an eight-channel part in a design that only requires four channels?

A: Yes. The MCP48FVB28-E/MQ can be used in applications requiring fewer than eight channels. Unused converter channels can remain unaddressed in firmware. The part maintains identical electrical performance and package compatibility.

Q: Are there supply voltage differences between substitute parts?

A: No. All substitute parts operate within the identical 2.7V to 5.5V supply range for both analog and digital supplies.
