W971GG6JB-25 – DDR2 SDRAM – Winbond

About this part

The Winbond W971GG6JB-25 is a 1-gigabit DDR2 SDRAM from Winbond’s specialty DRAM family, internally organized as 8,388,608 words x 8 banks x 16 bits (64M x 16). The -25 speed-grade variant is compliant with the JEDEC DDR2-800 (5-5-5) specification and operates over the commercial temperature range of 0°C to 85°C (T_CASE). Built on a low-power 1.8V SSTL_18 interface and housed in a lead-free, RoHS-compliant 84-ball WBGA package, this device is widely used as a long-lifecycle memory in embedded, industrial, networking, and consumer designs.

As a mature DDR2 component, the W971GG6JB-25 is increasingly difficult to source through authorized channels. Pacific Component Xchange specializes in locating and supplying exactly this kind of end-of-life and hard-to-find memory.

Key Features

• 1Gb DDR2 SDRAM, organized as 8,388,608 words x 8 banks x 16 bits (64M x 16)

Applications

• Networking and telecom equipment (routers, switches, line cards)
• Industrial control and automation systems
• Embedded computing and single-board computers
• Set-top boxes, digital signage, and consumer multimedia
• Printers, point-of-sale, and office equipment
• Legacy system maintenance and end-of-life product builds

Why Source W971GG6JB-25 from Pacific Component Xchange

DDR2 specialty DRAM like the W971GG6JB-25 has reached end-of-life status, making authorized-distributor stock scarce. Pacific Component Xchange is an independent distributor focused on obsolete and hard-to-find memory, giving engineers and procurement teams a reliable path to keep mature designs in production.

• Hard-to-find & obsolete sourcing: Deep access to specialty DRAM inventory other distributors no longer carry.
• Authenticity & quality: Inspection and verification processes to mitigate counterfeit risk on legacy parts.
• Global shipping: Fast, worldwide fulfillment to support production lines and field-service needs.
