Substitute Part Grouping Explanation

The E2144CS021 qualifies as a direct substitute for the E1144CS021 based on the following critical parameters:

• Display Technology: Both parts utilize TFT - Electronic Paper Display (EPD) technology with reflective black-and-white operation
• Resolution: Identical pixel configuration of 128 x 96 dots
• Interface Protocol: Both employ SPI communication interface
• Viewing Area: Matching dimensions of 29.31mm W x 21.98mm H
• Dot Pitch: Identical pitch specification of 0.23mm W x 0.23mm H
• Color Specification: Both feature black graphics on white background
• Backlight Configuration: Both operate without backlight
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The E2144CS021 represents an active product status variant within the same Aurora MB series, providing functional and mechanical compatibility with the obsolete E1144CS021.
