• Circuit configuration: 2 circuits (identical)
• Tap resolution: 256 taps (identical)
• Control interface: SPI (identical)
• Supply voltage range: 2.7V ~ 5.5V (identical)
• Package type: 14-TSSOP (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Tolerance: ±20% (identical)
• Temperature coefficient: 800ppm/°C (identical)
• Wiper resistance: 73Ω typical (identical)
• Cascade pin feature: Present (identical)

The only difference between these parts is the packaging format: MCP42010-I/ST is supplied in Tube packaging, while MCP42010T-I/ST is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are manufactured by Microchip Technology and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both MCP42010-I/ST and MCP42010T-I/ST are electrically and functionally identical components from Microchip Technology, both maintaining active product status. Selection between these parts should be based on packaging and supply requirements:

MCP42010-I/ST (Tube Packaging): Select this variant when tube packaging is specified in procurement requirements or when component handling and storage procedures require tube format.

MCP42010T-I/ST (Cut Tape & Digi-Reel® Packaging): Select this variant for automated assembly processes that require tape-and-reel format, or when cut tape packaging is preferred for component dispensing systems.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part. Current inventory levels support both options, with MCP42010-I/ST showing higher stock availability at 1664 units compared to 1306 units for MCP42010T-I/ST.

Frequently Asked Questions (FAQ)

Q: Can MCP42010T-I/ST be used as a direct replacement for MCP42010-I/ST?

A: Yes. Both parts are electrically and functionally identical with matching specifications across all critical parameters including resistance value, tap count, interface protocol, voltage range, temperature range, and package dimensions. The only difference is packaging format (Tube vs. Cut Tape & Digi-Reel®).

Q: What is the difference between Tube and Cut Tape & Digi-Reel® packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and storage. Cut Tape & Digi-Reel® packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance.

Q: Are there any compatibility issues when switching between these packaging formats?

A: No compatibility issues exist at the component level. The electrical and mechanical specifications are identical. Compatibility considerations apply only to assembly process requirements—verify that your assembly equipment can accommodate the selected packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MCP42010-I/ST and MCP42010T-I/ST are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that these components have no moisture sensitivity constraints. Standard moisture control procedures during storage and handling are not required, simplifying logistics and inventory management.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, from an electrical and functional standpoint. Both parts operate identically in circuit applications. Verify that your assembly process can accommodate the selected packaging format before implementation.
