W25Q128FVFAQ Equivalent & Substitute Parts

Part Overview

The W25Q128FVFAQ is a 128Mbit NOR Flash memory integrated circuit manufactured by Winbond Electronics in a 16-SOIC surface mount package. This device is classified as obsolete and is no longer in active production. The part is designed for non-volatile memory applications requiring SPI interface connectivity.

Due to its obsolete status, locating replacement inventory becomes necessary for ongoing production support, maintenance, and repair operations. Substitute parts must maintain functional equivalence in memory capacity, interface protocol, and package compatibility to ensure direct replacement capability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the W25Q128FVFAQ is determined by the following critical parameters:

Memory Capacity: Both the main part and substitute must provide 128Mbit storage capacity to maintain functional equivalence in data storage applications.

Memory Technology: The substitute must utilize FLASH - NOR technology to ensure compatibility with existing circuit designs and firmware implementations.

Base Product Number: Parts sharing the W25Q128 base product number indicate common core functionality and design lineage within the Winbond product family.

Manufacturer: Winbond Electronics maintains consistent pin configurations and electrical characteristics across the W25Q128 product line, enabling direct substitution.

Moisture Sensitivity Level: Both parts maintain MSL 3 classification, ensuring equivalent handling and storage requirements during manufacturing and assembly processes.

REACH Compliance: Both parts carry REACH Unaffected status, confirming equivalent regulatory compliance for European market applications.

The W25Q128JVJAQ qualifies as a substitute based on these parameters, offering active product status while maintaining the core specifications of the obsolete W25Q128FVFAQ.
