Substitute Part Grouping Explanation

Substitution between MCP4332T-104E/ST and MCP4332-104E/ST is valid based on identical electrical and mechanical parameters. Both parts share the same base product number (MCP4332), resistance value (100kΩ), circuit configuration (4 circuits), tap count (129), interface protocol (SPI), supply voltage range (1.8V ~ 5.5V), tolerance (±20%), temperature coefficient (150ppm/°C), package footprint (14-TSSOP), operating temperature range (-40°C ~ 125°C), and wiper resistance (75Ω typical). The sole distinction is packaging format: MCP4332T-104E/ST is supplied in Tape & Reel format, while MCP4332-104E/ST is supplied in Tube format. Both maintain identical RoHS3 compliance, MSL rating, and product status. Substitution is permissible when packaging format does not constrain assembly or procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

Both MCP4332T-104E/ST and MCP4332-104E/ST are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be determined by packaging and supply chain requirements. MCP4332T-104E/ST in Tape & Reel format is suitable for high-volume automated assembly operations. MCP4332-104E/ST in Tube format accommodates lower-volume applications or manual assembly workflows. Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can MCP4332-104E/ST replace MCP4332T-104E/ST in a circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube versus Tape & Reel). Circuit performance, pin configuration, and electrical specifications are identical.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is optimized for high-speed automated pick-and-place assembly. Tube packaging is used for lower-volume applications or manual assembly. Both formats contain the same component with identical specifications.

Q: Are there any compatibility concerns when switching between these part numbers?

A: No compatibility concerns exist. Both parts use the 14-TSSOP package footprint (0.173", 4.40mm Width) and are pin-for-pin compatible. PCB layout and schematic connections remain unchanged.

Q: Do both parts have the same supply voltage requirements?

A: Yes. Both MCP4332T-104E/ST and MCP4332-104E/ST operate across the identical supply voltage range of 1.8V to 5.5V.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 125°C. Temperature coefficient is 150ppm/°C for both variants.

Q: Are both parts RoHS compliant?

A: Yes. Both MCP4332T-104E/ST and MCP4332-104E/ST are ROHS3 compliant and REACH unaffected.

Q: What is the MSL rating for these components?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
