Substitute Part Grouping Explanation

Substitute parts for the MCP48FVB24T-20E/ST are determined by equivalence in the following critical parameters: 12-bit resolution, SPI data interface, external reference type, identical supply voltage ranges (2.7V ~ 5.5V for both analog and digital), matching INL/DNL specifications (±0.4LSB, ±0.05LSB), identical settling time (7.8µs typical), voltage-unbuffered output type, 20-TSSOP package configuration, surface mount mounting type, automotive grade classification, and AEC-Q100 qualification.

Substitutes are grouped into two categories based on D/A converter count:

Category 1: 4 D/A Converters (Direct Equivalents)

• MCP48FEB24T-20E/ST: Identical electrical specifications and D/A converter count with Cut Tape packaging
• MCP48FEB28T-20E/ST: Identical electrical specifications and D/A converter count with Cut Tape packaging

Category 2: 8 D/A Converters (Extended Functionality)

• MCP48FVB28T-20E/ST: Identical electrical specifications with doubled D/A converter count (8 vs. 4), available in Tape & Reel packaging

All substitute parts maintain Active product status, automotive-grade qualification, AEC-Q100 compliance, ROHS3 compliance, and REACH unaffected status.

Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the primary part.

For Extended Functionality (8 D/A Converters):

MCP48FVB28T-20E/ST provides identical electrical performance with doubled D/A converter count (8 converters versus 4). This part is suitable for applications requiring additional analog output channels within the same package footprint and electrical specifications. The MCP48FVB28T-20E/ST is available in Tape & Reel packaging with 1906 units in stock and includes Moisture Sensitivity Level (MSL) 3 specification (168 Hours). This part maintains all automotive-grade qualifications and compliance certifications.

All substitute parts are Active status products from Microchip Technology, ensuring continued manufacturing support and availability.

Frequently Asked Questions (FAQ)

Q: Can MCP48FEB24T-20E/ST be used as a direct replacement for MCP48FVB24T-20E/ST?

A: Yes. MCP48FEB24T-20E/ST is a direct electrical equivalent with identical 12-bit resolution, 4 D/A converter count, SPI interface, supply voltage ranges (2.7V ~ 5.5V), settling time (7.8µs typical), INL/DNL specifications (±0.4LSB, ±0.05LSB), operating temperature range (-40°C ~ 125°C), and 20-TSSOP package configuration. Both parts carry automotive-grade classification and AEC-Q100 qualification. The primary difference is packaging format: MCP48FVB24T-20E/ST is supplied in Cut Tape, while MCP48FEB24T-20E/ST is also supplied in Cut Tape.

Q: What is the difference between MCP48FVB24T-20E/ST and MCP48FVB28T-20E/ST?

A: The primary difference is the number of D/A converters: MCP48FVB24T-20E/ST contains 4 converters, while MCP48FVB28T-20E/ST contains 8 converters. All other electrical specifications are identical, including 12-bit resolution, SPI interface, external reference type, supply voltage ranges, settling time, and INL/DNL performance. Both parts use the 20-TSSOP package and maintain automotive-grade AEC-Q100 qualification. MCP48FVB28T-20E/ST is available in Tape & Reel packaging and includes MSL 3 specification.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the identical 20-TSSOP package configuration (0.173" width, 4.40mm). Pin-to-pin compatibility is maintained across MCP48FVB24T-20E/ST, MCP48FEB24T-20E/ST, and MCP48FEB28T-20E/ST for 4-converter configurations. MCP48FVB28T-20E/ST also uses the same 20-TSSOP package and is pin-compatible for PCB placement, though the 8-converter configuration may require firmware or software modifications to utilize the additional output channels.
