Parameter Comparison

Engineering Selection Recommendations

All three parts—MCP48FEB28-20E/ST, MCP48FEB24-20E/ST, and MCP48FVB24-20E/ST—are active production components from Microchip Technology with identical electrical specifications and mechanical compatibility. Each part carries automotive-grade qualification and AEC-Q100 certification, confirming suitability for demanding industrial and automotive applications.

Selection between these parts is based on availability and supply chain considerations rather than functional differences. The MCP48FEB28-20E/ST and MCP48FEB24-20E/ST share identical specifications and differ only in base product designation. The MCP48FVB24-20E/ST provides an alternative source with the same electrical and mechanical characteristics.

All parts comply with ROHS3 environmental standards and carry REACH unaffected status, meeting regulatory requirements for global deployment. The 20-TSSOP surface mount package ensures compatibility with standard PCB assembly processes and automated placement equipment.

Frequently Asked Questions (FAQ)

Q: Can MCP48FEB24-20E/ST be used as a direct replacement for MCP48FEB28-20E/ST?

A: Yes. Both parts share identical electrical specifications, including 12-bit resolution, 4 D/A converters, 7.8µs settling time, SPI interface, and 2.7V to 5.5V supply range. The 20-TSSOP package and pin configuration are identical, enabling direct PCB substitution without design modification.

Q: What is the difference between MCP48FEB24-20E/ST and MCP48FVB24-20E/ST?

A: Both parts are electrically and mechanically equivalent with identical performance specifications. The difference lies in the base product designation (FEB versus FVB series). Both are automotive-grade, AEC-Q100 qualified, and ROHS3 compliant. Selection is based on supply availability.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry automotive-grade classification and AEC-Q100 qualification, confirming compliance with automotive reliability and quality standards. Operating temperature range of -40°C to 125°C supports automotive environmental conditions.

Q: Is the 20-TSSOP package compatible with standard PCB assembly equipment?

A: Yes. The 20-TSSOP surface mount package is a standard industry format compatible with automated pick-and-place and reflow soldering processes. The 0.173" width and 4.40mm package dimensions conform to established PCB assembly specifications.

Q: Do these parts require firmware changes when substituting one for another?

A: No. All three parts implement identical SPI serial interfaces and external reference architectures. Firmware and software interfaces remain unchanged during substitution.

Q: What is the moisture sensitivity level for these parts?

A: MCP48FEB28-20E/ST and MCP48FEB24-20E/ST specifications do not include MSL data in the provided parameters. MCP48FVB24-20E/ST carries MSL 3 (168 Hours) rating, indicating standard moisture handling requirements for surface mount components.

Q: Are these parts REACH compliant?
