Substitute Part Grouping Explanation

Substitution eligibility for the MCP3428T-E/SL is determined by strict equivalence across the following critical parameters:

• Resolution and Architecture: 16-bit Sigma-Delta conversion capability
• Channel Configuration: 4 differential input channels
• Interface Protocol: I2C digital communication
• Signal Conditioning: Integrated MUX-PGA-ADC configuration with internal reference
• Supply Voltage Compatibility: 2.7V to 5.5V operation for both analog and digital supplies
• Package and Pinout: 14-SOIC surface mount package with identical mechanical dimensions
• Temperature Rating: -40°C to 125°C operating range
• Compliance Status: RoHS3 compliance and REACH unaffected classification

The MCP3428-E/SL meets all substitution criteria as a direct equivalent part from the same manufacturer base product family (MCP3428).

Parameter Comparison

Engineering Selection Recommendations

The MCP3428-E/SL is a direct functional equivalent to the MCP3428T-E/SL. Both components share identical electrical specifications, package configuration, and compliance certifications. Selection between these parts may be based on packaging format availability (Tube for MCP3428-E/SL versus standard packaging for MCP3428T-E/SL) and current inventory status. Both parts maintain Active product status with full RoHS3 compliance and REACH unaffected classification, ensuring regulatory compliance for industrial and commercial applications. The choice between these equivalents does not introduce any functional, thermal, or electrical performance differences in circuit implementation.
