AT25DF256-SSHNGU-T Equivalent & Substitute Parts

Part Overview

The AT25DF256-SSHNGU-T is a 256Kbit Serial Peripheral Interface (SPI) FLASH memory IC manufactured by Renesas Electronics Corporation. This non-volatile memory device operates at 104 MHz with a supply voltage range of 1.65V to 3.6V and is housed in an 8-SOIC surface mount package. The part is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified when packaging configuration or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the AT25DF256-SSHNGU-T is limited to the AT25DF256-SSHN-T based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical parameters: memory capacity (256Kbit), organization (32K x 8), interface protocol (SPI), clock frequency (104 MHz), write cycle times (8µs word, 2.5ms page), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and physical package dimensions (8-SOIC, 0.154" width, 3.90mm). The sole difference between these parts is the packaging configuration: the main part (AT25DF256-SSHNGU-T) is supplied in tube packaging, while the substitute (AT25DF256-SSHN-T) is supplied in Tape & Reel (TR) format. Both maintain identical RoHS3 compliance, MSL rating of 1, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25DF256-SSHNGU-T and AT25DF256-SSHN-T are functionally equivalent for circuit design and application requirements. Selection between these parts should be based on procurement and assembly process requirements. The tube-packaged variant (AT25DF256-SSHNGU-T) is suitable for lower-volume manual assembly or hand-pick operations. The Tape & Reel packaged variant (AT25DF256-SSHN-T) is optimized for automated pick-and-place assembly processes and higher-volume production runs. Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance. The choice between these variants does not affect circuit functionality, signal integrity, or system reliability.

Frequently Asked Questions (FAQ)

Q: Are AT25DF256-SSHNGU-T and AT25DF256-SSHN-T electrically interchangeable? A: Yes. Both parts are electrically identical with matching memory capacity, interface protocol, clock frequency, voltage specifications, and operating temperature range. They produce identical circuit behavior.

Q: What is the difference between tube and Tape & Reel packaging? A: Tube packaging supplies individual components in a plastic tube suitable for manual handling and small-quantity assembly. Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated assembly equipment. The components themselves are identical.

Q: Can I use AT25DF256-SSHN-T in place of AT25DF256-SSHNGU-T in my design? A: Yes, provided your assembly process supports Tape & Reel format. The electrical and mechanical specifications are identical, and the component will function identically in the circuit.

Q: Are there any compliance or certification differences between these parts? A: No. Both parts carry identical RoHS3 compliance, REACH status, and Moisture Sensitivity Level ratings. Regulatory and environmental compliance is equivalent.

Q: Which part should I specify for high-volume production? A: The AT25DF256-SSHN-T (Tape & Reel format) is recommended for high-volume automated assembly due to compatibility with standard pick-and-place equipment and reduced handling costs.
