Key Parameters

Substitute Part Grouping Explanation

Substitution of the W25Q256FVFIF is determined by strict equivalence across the following critical parameters:

Memory Capacity & Organization: All substitute parts maintain 256Mbit capacity with 32M x 8 organization, ensuring direct data storage compatibility.

Package & Mounting: All substitutes use identical 16-SOIC (0.295", 7.50mm Width) Surface Mount packaging, enabling direct PCB placement without layout modifications.

Memory Interface: All substitutes support SPI - Quad I/O protocol, maintaining communication protocol compatibility with host systems designed for the original part.

Voltage Supply Range: All substitutes operate within the 2.7V ~ 3.6V range, ensuring compatibility with existing power delivery systems.

Operating Temperature Range: All substitutes maintain the -40°C ~ 85°C operating window, preserving thermal performance specifications.

Compliance Standards: All substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute parts W25Q256JVFIM and W25Q256JVFIQ operate at 133 MHz clock frequency, exceeding the original 104 MHz specification while remaining backward compatible with systems designed for the lower frequency.

Parameter Comparison

Engineering Selection Recommendations

W25Q256JVFIM: This substitute part is Active in product status and maintains full electrical and mechanical compatibility with the W25Q256FVFIF. The 133 MHz clock frequency provides enhanced performance over the original 104 MHz specification. This part is suitable for applications where the original part is no longer available and performance improvement is acceptable.

W25Q256JVFIQ: This substitute part is Active in product status with verified programmability certification. The 133 MHz clock frequency and Tray packaging provide enhanced performance and supply chain advantages. This part offers the highest inventory availability (55,400 Pcs) and is suitable for high-volume production requirements. The verified programmability status provides additional assurance for system integration.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met. Selection between W25Q256JVFIM and W25Q256JVFIQ should be based on packaging requirements (Tray vs. standard) and programmability verification needs.

Frequently Asked Questions (FAQ)

Q: Can W25Q256JVFIM or W25Q256JVFIQ be used as direct replacements for W25Q256FVFIF?

A: Yes. Both substitute parts maintain identical memory capacity (256Mbit), organization (32M x 8), package type (16-SOIC), mounting method (Surface Mount), voltage supply range (2.7V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The 133 MHz clock frequency of the substitutes exceeds the original 104 MHz specification and is backward compatible with systems designed for the lower frequency.

Q: What is the difference between W25Q256JVFIM and W25Q256JVFIQ?

A: Both parts are electrically identical with 256Mbit capacity, 133 MHz clock frequency, and identical package specifications. The primary differences are packaging format (W25Q256JVFIQ is supplied in Tray) and programmability verification status (W25Q256JVFIQ has verified programmability certification). W25Q256JVFIQ offers significantly higher inventory availability.

Q: Are there any protocol differences between the main part and substitutes?

A: The W25Q256FVFIF supports SPI - Quad I/O and QPI protocols. The substitute parts W25Q256JVFIM and W25Q256JVFIQ support SPI - Quad I/O protocol. Both substitutes are compatible with SPI - Quad I/O applications. Applications requiring QPI protocol should verify compatibility with the substitute parts.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All parts including W25Q256FVFIF, W25Q256JVFIM, and W25Q256JVFIQ are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the impact of the higher clock frequency in the substitute parts?

A: The 133 MHz clock frequency in W25Q256JVFIM and W25Q256JVFIQ exceeds the original 104 MHz specification. This provides enhanced data transfer rates while maintaining full backward compatibility with systems designed for 104 MHz operation. No system modifications are required.

Q: Which substitute part should be selected for new designs?

A: W25Q256JVFIQ is recommended for new designs due to Active product status, verified programmability certification, and superior inventory availability (55,400 Pcs). The Tray packaging is standard for production environments.
