MCP48FVB24T-E/MQ Equivalent & Substitute Parts

Part Overview

The MCP48FVB24T-E/MQ 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 output, unbuffered configuration, and SPI data interface. The device operates across a supply voltage range of 2.7V to 5.5V for both analog and digital supplies, with a typical settling time of 7.8µs. The MCP48FVB24T-E/MQ is classified as an active product with automotive-grade qualification (AEC-Q100) and is RoHS3 compliant.

Substitute parts are identified when equivalent electrical performance, functional specifications, and mechanical compatibility are maintained across the product line, allowing for design flexibility and supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP48FVB24T-E/MQ is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• 12-bit resolution with 4 independent D/A converters
• Identical settling time of 7.8µs (typical)
• Voltage output, unbuffered configuration
• SPI serial data interface
• External reference type
• Matching supply voltage ranges: 2.7V to 5.5V (analog and digital)
• Identical INL/DNL specifications: ±0.4LSB and ±0.05LSB

Mechanical & Environmental Specifications:

• 20-VQFN (5x5) package with exposed pad
• Surface mount mounting type
• Automotive-grade classification
• AEC-Q100 qualification
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance

Packaging Variation: The primary distinction between the main part and its substitute is the packaging format: the MCP48FVB24T-E/MQ is supplied in Cut Tape (CT), while the MCP48FEB28T-E/MQ is supplied in Tape & Reel (TR). Both parts share identical electrical performance and physical package specifications, making them functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP48FVB24T-E/MQ and MCP48FEB28T-E/MQ are active products from Microchip Technology with identical electrical specifications and automotive-grade qualification. Selection between these parts is determined by packaging and supply requirements rather than functional performance.

MCP48FVB24T-E/MQ (Cut Tape): Suitable for applications requiring smaller order quantities, prototype development, or component-level procurement where individual unit handling is preferred.

MCP48FEB28T-E/MQ (Tape & Reel): Appropriate for high-volume production environments where automated pick-and-place assembly processes are utilized. Tape & Reel packaging provides improved handling efficiency and cost optimization for large-scale manufacturing.

Both parts maintain full compliance with AEC-Q100 automotive qualification standards and RoHS3 environmental requirements. The identical 20-VQFN (5x5) package footprint ensures direct PCB layout compatibility without design modification. No electrical performance degradation or functional limitation occurs when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Are the MCP48FVB24T-E/MQ and MCP48FEB28T-E/MQ electrically identical?

A: Yes. Both parts share identical electrical specifications, including 12-bit resolution, 4 D/A converters, 7.8µs settling time, SPI interface, and matching supply voltage ranges (2.7V to 5.5V). INL/DNL performance is identical at ±0.4LSB and ±0.05LSB.

Q: What is the only difference between these two parts?

A: The packaging format. The MCP48FVB24T-E/MQ is supplied in Cut Tape (CT), while the MCP48FEB28T-E/MQ is supplied in Tape & Reel (TR). The physical package dimensions and pin configuration remain identical.

Q: Can I use MCP48FEB28T-E/MQ in place of MCP48FVB24T-E/MQ on my PCB?

A: Yes. Both parts use the identical 20-VQFN (5x5) package with exposed pad. No PCB layout modification is required for direct substitution.

Q: Are both parts automotive-qualified?

A: Yes. Both the MCP48FVB24T-E/MQ and MCP48FEB28T-E/MQ carry automotive-grade classification with AEC-Q100 qualification and operate across the -40°C to 125°C temperature range.

Q: Which part should I select for high-volume production?

A: The MCP48FEB28T-E/MQ (Tape & Reel) is optimized for high-volume automated assembly processes. Cut Tape format (MCP48FVB24T-E/MQ) is more suitable for lower-volume or prototype applications.

Q: Do both parts comply with environmental regulations?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Is there a performance difference in settling time between the two parts?

A: No. Both parts have identical settling time specifications of 7.8µs (typical).

Q: Can I mix Cut Tape and Tape & Reel parts in the same production run?

A: Yes, from an electrical and functional standpoint. However, assembly process compatibility should be evaluated based on your manufacturing equipment and handling procedures.
