Winbond Electronics W25R
W25R variants from Winbond Electronics
W25R Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
Key Features
- Footprint / package: 8-WDFN Exposed PadSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 256JWEIQ, 256JWPIQ. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- general-purpose circuits — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 W25R part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| W25R256JWEIQ | Package: 8-WDFN Exposed Pad | Mounting Type: Surface Mount | Supply Voltage: 1.7V ~ 1.95V | Memory Size: 256Mb (32M x 8) | Operating Temperature: -40°C ~ 85°C | 8-WDFN Exposed Pad | Winbond Electronics | Active | Compliant | In Stock | |
| W25R256JWPIQ | Package: 8-WDFN Exposed Pad | Mounting Type: Surface Mount | Supply Voltage: 1.7V ~ 1.95V | Memory Size: 256Mb (32M x 8) | Operating Temperature: -40°C ~ 85°C | 8-WDFN Exposed Pad | Winbond Electronics | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on W25R map to package, grade, and reel options.
How to Choose the Right W25R Variant
Match the footprint first
Packages here: 8-WDFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For W25R, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "W25R" — include the full suffix (e.g. 256JWEIQ, 256JWPIQ). RFQ with reel/tube preference and required date code.
