Engineering Selection Recommendations

The GD5F2GM7REWIGY is available as an active product from the same manufacturer, providing supply continuity for applications currently using the GD5F2GQ4RF9IGR. Both parts share identical memory capacity, interface protocol, voltage specifications, and operating temperature range.

The substitute part operates at a lower clock frequency (104 MHz versus 120 MHz) and features a different memory organization (512M x 4 versus 256M x 8). The package footprint differs between the two parts: the main part uses an 8-LGA (6x8) form factor while the substitute uses an 8-WSON (5x6) form factor. These differences require PCB layout and firmware evaluation to confirm compatibility with the target application.

The GD5F2GM7REWIGY's active product status ensures ongoing availability and support, whereas the GD5F2GQ4RF9IGR is in Last Time Buy status. Both parts maintain identical moisture sensitivity levels and comply with RoHS3 requirements.

Frequently Asked Questions (FAQ)

Q: Can the GD5F2GM7REWIGY directly replace the GD5F2GQ4RF9IGR without PCB modifications?

A: No. The package form factors differ (8-LGA versus 8-WSON), requiring PCB layout changes. Pin compatibility must be verified against the respective datasheets before implementation.

Q: What is the impact of the 16 MHz clock frequency difference?

A: The substitute operates at 104 MHz compared to the main part's 120 MHz. Applications must confirm that this lower frequency meets timing requirements. Firmware may require adjustment to accommodate the reduced clock speed.

Q: Are both parts compatible with the same firmware?

A: Both parts support SPI Quad I/O interface and identical voltage specifications. However, differences in memory organization (256M x 8 versus 512M x 4) and clock frequency may require firmware validation and potential modifications.

Q: What are the packaging considerations for this substitution?

A: The main part uses 8-LGA (6x8) packaging while the substitute uses 8-WSON (5x6) packaging. The substitute has a smaller footprint. PCB redesign is necessary, including trace routing and component placement adjustments.

Q: Is the GD5F2GM7REWIGY suitable for long-term production?

A: Yes. The substitute part maintains Active product status, ensuring continued availability and manufacturer support, unlike the main part which is in Last Time Buy status.

Q: Do both parts have identical supply voltage requirements?

A: Yes. Both parts operate within the 1.7V to 2V supply voltage range and maintain the same operating temperature range of -40°C to 85°C.
