GD25VE40CSIGR Equivalent & Substitute Parts

Part Overview

The GD25VE40CSIGR is a 4Mbit NOR Flash memory IC manufactured by GigaDevice Semiconductor with SPI and Quad I/O interface capabilities. This Surface Mount device operates at 104 MHz and is housed in an 8-SOIC package. The part is currently in Active product status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent memory capacity, interface type, and electrical specifications align within acceptable operational parameters, enabling design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GD25VE40CSIGR is determined by the following critical parameters:

Memory capacity must equal 4Mbit with 512K x 8 organization
Interface must support SPI with Quad I/O capability
Operating temperature range must encompass -40°C to 85°C
Supply voltage range must be compatible with system requirements
Package must be 8-SOIC form factor for PCB compatibility
RoHS3 compliance required for regulatory alignment

The MX25R4035FM1IH1 meets these substitution criteria. Both devices share identical memory capacity, organization, interface type, temperature range, and package classification. Voltage supply ranges overlap within the 2.1V to 3.6V window. Clock frequency variance (104 MHz vs. 108 MHz) represents a performance enhancement rather than a limitation.

Engineering Selection Recommendations

The GD25VE40CSIGR is the primary selection for new designs due to its Active product status. This designation ensures ongoing manufacturer support, availability, and process continuity.

The MX25R4035FM1IH1 serves as a substitute for existing designs or legacy applications. Its Not For New Designs status indicates that Macronix has transitioned this product line, making it suitable only for maintenance, repair, or continuation of established applications. Both devices maintain ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.32.0071).

Physical package dimensions differ between the two devices. The GD25VE40CSIGR measures 5.30mm in width, while the MX25R4035FM1IH1 measures 3.90mm. This dimensional variance requires PCB layout verification before substitution in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can MX25R4035FM1IH1 replace GD25VE40CSIGR in new product designs?

A: No. The MX25R4035FM1IH1 carries a Not For New Designs status. New designs should specify the GD25VE40CSIGR to ensure long-term availability and manufacturer support.

Q: Are the memory capacities and interfaces identical?

A: Yes. Both devices provide 4Mbit capacity with 512K x 8 organization and SPI Quad I/O interface. They are functionally equivalent in memory architecture.

Q: What is the significance of the clock frequency difference?

A: The MX25R4035FM1IH1 operates at 108 MHz compared to the GD25VE40CSIGR at 104 MHz. This represents a performance increase and does not create compatibility issues in systems designed for the lower frequency.

Q: Do the voltage supply ranges differ?

A: The MX25R4035FM1IH1 supports 1.65V to 3.6V, while the GD25VE40CSIGR supports 2.1V to 3.6V. The MX25R4035FM1IH1 offers extended low-voltage capability. Both operate within the overlapping 2.1V to 3.6V range.

Q: Are there package dimension considerations?

A: Yes. The GD25VE40CSIGR package width is 5.30mm; the MX25R4035FM1IH1 is 3.90mm. Both use 8-SOIC form factor. PCB layout and footprint compatibility must be verified before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant, REACH Unaffected, and share identical ECCN and HTSUS classifications.
