Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the W25M02GVTCIT is determined by strict equivalence across the following critical parameters:

Memory Capacity & Organization: The substitute part must provide identical 2Gbit capacity with 256M x 8 memory organization to ensure functional compatibility with existing firmware and memory mapping schemes.

Interface Specification: SPI Quad I/O interface is mandatory. The substitute must support identical signaling protocols and clock frequency of 104 MHz to maintain timing compatibility with host controllers.

Electrical Characteristics: Supply voltage range (2.7V ~ 3.6V) and operating temperature range (-40°C ~ 85°C) must be identical or encompassing to ensure operation across all specified environmental conditions.

Package & Mounting: The 24-TFBGA (8x6) surface mount package is required for PCB layout compatibility. Pin count, pitch, and footprint must be identical.

Compliance Standards: RoHS3 compliance and MSL rating of 3 (168 Hours) must be maintained for manufacturing and environmental requirements.

The W25N02KVTCIU meets all substitution criteria and is classified as a direct equivalent.
