Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPD23749DREP is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 16-SOIC (0.154", 3.90mm Width) package to ensure PCB footprint compatibility
• Functional Classification: Both components must operate as driver/receiver interface circuits within the same electrical category
• Regulatory Compliance: Substitute parts must maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements
• Supply Voltage Range: Operating voltage specifications must be compatible with system requirements

The AM26C31MDREP meets these substitution criteria as an active alternative component.
