MCP3428T-E/ST Equivalent & Substitute Parts

Part Overview

The MCP3428T-E/ST is a 16-bit Sigma-Delta analog-to-digital converter manufactured by Microchip Technology, designed for multi-channel data acquisition applications. This device features 4 differential inputs, integrated programmable gain amplifier (PGA), and I2C digital interface, operating across a wide supply voltage range of 2.7V to 5.5V. The component is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or distribution channel requirements differ while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The MCP3428T-E/ST and MCP3428-E/ST are direct equivalents from Microchip Technology. Substitution eligibility is determined by the following critical parameters that remain identical across both parts:

• 16-bit resolution with Sigma-Delta architecture
• 4 differential input channels
• I2C communication protocol
• 15 samples per second sampling rate
• 2.7V to 5.5V supply voltage range (both analog and digital)
• -40°C to 125°C operating temperature range
• 14-TSSOP surface mount package with identical physical dimensions
• Internal voltage reference
• Integrated PGA with selectable address configuration

The only difference between these parts is the packaging format: MCP3428T-E/ST is supplied in Tape & Reel (TR) format, while MCP3428-E/ST is supplied in Tube format. Both maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MCP3428T-E/ST and MCP3428-E/ST are active production components from Microchip Technology with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on procurement and assembly requirements:

• MCP3428T-E/ST (Tape & Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging is required for pick-and-place equipment.
• MCP3428-E/ST (Tube): Suitable for lower-volume applications, manual assembly, or when tube packaging is specified in procurement requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across industrial and commercial applications. The unlimited MSL rating (MSL 1) indicates these components have no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can MCP3428-E/ST be used as a direct replacement for MCP3428T-E/ST?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube vs. Tape & Reel). Substitution is valid for any application where the packaging format does not conflict with assembly or procurement specifications.

Q: Are there any differences in electrical performance between these two part numbers?

A: No. Both parts have identical 16-bit resolution, 4 differential inputs, I2C interface, 15 SPS sampling rate, and 2.7V to 5.5V supply voltage range. Electrical performance is equivalent across all operating conditions.

Q: What is the significance of the packaging difference?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume manufacturing. Tube packaging is used for manual assembly, lower-volume production, or when components are handled individually. The physical component and pinout remain identical.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes, provided the assembly equipment is compatible with the respective packaging format. Both use the same 14-TSSOP surface mount package with identical pin configuration and spacing.

Q: Do these parts have the same compliance certifications?

A: Yes. Both MCP3428T-E/ST and MCP3428-E/ST are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the base product number for these parts?

A: The base product number is MCP3428. Both MCP3428T-E/ST and MCP3428-E/ST are variants of this base product, differentiated only by packaging format and temperature/packaging suffix designations.
