MCP42010T-E/ST Equivalent & Substitute Parts

Part Overview

The MCP42010T-E/ST is a digital potentiometer manufactured by Microchip Technology, classified as a data acquisition component. This integrated circuit provides 10kΩ resistance with 256 taps across 2 circuits, controlled via SPI interface. The device is currently in active production status with 1015 units available in tape & reel packaging. Alternative part sourcing becomes necessary due to packaging availability, inventory constraints, or supply chain requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MCP42010T-E/ST is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ (exact match required)
• Circuit configuration: 2 circuits (exact match required)
• Tap count: 256 taps (exact match required)
• Control interface: SPI (exact match required)
• Supply voltage range: 2.7V ~ 5.5V (exact match required)
• Package type: 14-TSSOP (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)

The substitute part MCP42010-E/ST meets all electrical and mechanical criteria for direct substitution. The primary difference is packaging format: the main part is supplied in tape & reel configuration, while the substitute is supplied in tube packaging. Both variants share identical device specifications, performance characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both MCP42010T-E/ST and MCP42010-E/ST are active production components from Microchip Technology with identical electrical specifications and compliance certifications. Selection between these parts should be based on packaging requirements and supply availability:

• MCP42010T-E/ST: Tape & reel packaging, 1015 units in stock. Suitable for automated assembly processes requiring continuous reel feed.
• MCP42010-E/ST: Tube packaging, 1900 units in stock. Suitable for manual assembly, lower-volume production, or applications where reel packaging is not required.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings. No functional or performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Can MCP42010-E/ST replace MCP42010T-E/ST in my application?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tube versus tape & reel). Functional performance, electrical characteristics, and compliance certifications are identical.

Q: What is the difference between tape & reel and tube packaging?

A: Tape & reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Tube packaging supplies components in a cylindrical container suitable for manual handling or lower-volume assembly processes. Both formats contain the same component.

Q: Are there any PCB layout or soldering differences between these parts?

A: No. Both parts use the 14-TSSOP package with identical pin configuration, spacing, and soldering requirements. PCB layouts are fully interchangeable.

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

A: Yes. Both MCP42010T-E/ST and MCP42010-E/ST operate across 2.7V to 5.5V supply voltage range with identical performance characteristics.

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

A: Both parts operate across -40°C to 125°C. Temperature coefficient is 800ppm/°C for both variants.

Q: Are both parts RoHS compliant?

A: Yes. Both MCP42010T-E/ST and MCP42010-E/ST are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).
