Substitute Part Grouping Explanation

The GD25WD20CTIGR qualifies as a direct substitute for the GD25VE20CTIGR based on the following critical parameters:

Memory Capacity & Organization: Both devices provide 2Mbit capacity with 256K x 8 organization
Interface Protocol: Both support SPI with Quad I/O functionality
Package & Mounting: Identical 8-SOIC surface mount package (0.154", 3.90mm Width)
Temperature Range: Both operate across -40°C to 85°C
Compliance Standards: Both are ROHS3 compliant with identical MSL rating of 3 (168 Hours)
Manufacturer: Both manufactured by GigaDevice Semiconductor (HK) Limited

The primary distinction is the voltage supply range, where the substitute part extends lower voltage operation capability.
