Key Parameters

Substitute Part Grouping Explanation

The MCP4341-104E/ST qualifies as a direct substitute for the MCP4341T-104E/ST based on identical electrical specifications and mechanical parameters. Both parts share the same base product number (MCP4341), resistance value (100kΩ), circuit configuration (4 circuits), tap count (129), interface protocol (SPI), memory architecture (non-volatile), supply voltage range (1.8V ~ 5.5V), tolerance (±20%), temperature coefficient (150ppm/°C), operating temperature range (-40°C ~ 125°C), and package form factor (20-TSSOP). The substitution is valid across all functional and performance criteria. The only difference is packaging configuration: the main part is supplied in Tape & Reel format, while the substitute is supplied in Tube format.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP4341T-104E/ST and MCP4341-104E/ST are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain availability. The Tape & Reel format (MCP4341T-104E/ST) is optimized for automated assembly processes, while the Tube format (MCP4341-104E/ST) is suitable for manual handling and smaller volume applications. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. Current inventory levels support both configurations, with the Tube format offering higher stock availability (1650 pcs vs. 815 pcs).

Frequently Asked Questions (FAQ)

Q: Can MCP4341-104E/ST replace MCP4341T-104E/ST in production? A: Yes. Both parts are electrically and mechanically identical. The substitution is valid for all functional applications. The difference is packaging format only.

Q: What is the difference between Tape & Reel and Tube packaging? A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Tube packaging is used for manual component handling and lower-volume applications. Both formats contain the same component.

Q: Are there any compliance differences between these parts? A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity ratings (MSL 1 - Unlimited).

Q: Which part should I select for high-volume manufacturing? A: The Tape & Reel format (MCP4341T-104E/ST) is recommended for automated assembly lines. The Tube format (MCP4341-104E/ST) is suitable for lower-volume or manual assembly processes.

Q: Are the electrical specifications identical? A: Yes. Both parts have identical resistance (100kΩ), tap count (129), circuit configuration (4 circuits), interface (SPI), supply voltage range (1.8V ~ 5.5V), tolerance (±20%), temperature coefficient (150ppm/°C), and operating temperature range (-40°C ~ 125°C).
