Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP4231T-104E/ST is determined by strict equivalence across the following critical parameters: resistance value (100k Ohm), circuit count (2), tap resolution (129), interface protocol (SPI), supply voltage range (1.8V ~ 5.5V), operating temperature range (-40°C ~ 125°C), package configuration (14-TSSOP), and compliance certifications (ROHS3). The primary distinction between the main part and substitute relates to packaging format: the MCP4231T-104E/ST is supplied in Tape & Reel format, while the MCP4231-104E/ST is supplied in Tube format. Both variants maintain identical electrical specifications, mechanical dimensions, and functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP4231T-104E/ST and MCP4231-104E/ST are active production components from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The Tape & Reel format (MCP4231T-104E/ST) is optimized for automated assembly processes, while the Tube format (MCP4231-104E/ST) is suitable for manual handling and smaller volume applications. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Are MCP4231T-104E/ST and MCP4231-104E/ST electrically interchangeable?

A: Yes. Both parts are manufactured by Microchip Technology with identical electrical specifications, including 100k Ohm resistance, 2 circuits, 129 taps, SPI interface, 1.8V to 5.5V supply voltage, and -40°C to 125°C operating temperature range.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. MCP4231T-104E/ST is supplied in Tape & Reel format, while MCP4231-104E/ST is supplied in Tube format. The "T" designation in the main part number indicates Tape & Reel packaging.

Q: Can I use the Tube packaged version in automated assembly?

A: Tube packaging is designed for manual handling and smaller volume applications. For high-volume automated assembly, Tape & Reel format is the standard choice.

Q: Are both parts RoHS compliant?

A: Yes. Both MCP4231T-104E/ST and MCP4231-104E/ST are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Do these parts have the same pin configuration?

A: Yes. Both parts use the 14-TSSOP package with identical pin assignments and mechanical dimensions (0.173" width, 4.40mm).

Q: What is the memory type for these digital potentiometers?

A: Both parts feature volatile memory, meaning resistance settings are not retained after power loss.
