MCP3301T-CI/MS Equivalent & Substitute Parts

Part Overview

The MCP3301T-CI/MS is a 13-bit Analog to Digital Converter (ADC) manufactured by Microchip Technology, designed for single-channel differential input applications. This SAR (Successive Approximation Register) architecture device operates at a 100 kHz sampling rate with SPI digital interface and external voltage reference configuration. The component is actively produced and ROHS3 compliant, making it suitable for modern industrial and consumer electronics applications requiring precision analog signal acquisition.

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, inventory optimization, or specific packaging requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP3301T-CI/MS is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: Both main and substitute parts must maintain 13-bit resolution at 100 kHz sampling rate
• Input Configuration: Single differential input channel with identical signal conditioning
• Digital Interface: SPI protocol compatibility
• Supply Voltage Requirements: 5V analog and digital supply voltages
• Package and Pinout: 8-MSOP surface mount package with identical pin configuration
• Temperature Range: -40°C to 85°C operating specification
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The MCP3301-CI/MS qualifies as a direct substitute based on identical electrical specifications and package configuration. The only distinction is packaging format (Tube versus standard supplier packaging), which does not affect component functionality or performance.

Parameter Comparison

Engineering Selection Recommendations

The MCP3301-CI/MS is a direct functional equivalent to the MCP3301T-CI/MS. Both components share identical electrical specifications, pin configuration, and compliance certifications. Selection between these parts should be based on:

• Product Status: Both parts are actively manufactured by Microchip Technology
• Compliance Requirements: Both maintain ROHS3 compliance and MSL Level 1 rating, suitable for standard and moisture-sensitive applications
• Packaging Format: The MCP3301-CI/MS is supplied in Tube packaging, while the MCP3301T-CI/MS uses standard supplier packaging. This distinction affects handling and storage procedures but not component performance
• Inventory Availability: Selection may be driven by stock levels and supply chain requirements

No performance degradation or functional compromise occurs when substituting between these parts in applications requiring 13-bit differential analog-to-digital conversion at 100 kHz sampling rate with SPI interface.
