Cross-reference / replacement · Winbond → GigaDevice
- Density:

Compatibility & sourcing notes
Same SOIC-8 footprint and compatible standard/dual-SPI command set (read, 4KB erase, page-program, JEDEC ID), so GD25Q/GD25D drops onto W25X designs that use standard or dual SPI. Note: W25X is the older Dual-SPI family while GD25Q adds Quad (SR2 QE bit), and the JEDEC manufacturer ID differs (GD 0xC8 vs Winbond 0xEF) — update any ID check and match density; GD25D is the closest non-Quad match.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
