AT25DF011-SSHN-B Equivalent & Substitute Parts

Part Overview

The AT25DF011-SSHN-B is a 1Mbit Serial Peripheral Interface (SPI) FLASH memory IC manufactured by Renesas Electronics Corporation. This non-volatile memory device operates at 104 MHz and is housed in an 8-SOIC surface mount package. The part is currently in active production status with 3033 units available in new original stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and interface protocol.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25DF011-SSHN-B is determined by the following critical parameters:

• Memory Capacity & Organization: 1Mbit capacity with 128K x 8 organization
• Interface Protocol: SPI communication standard
• Clock Frequency: 104 MHz operation
• Supply Voltage: 1.65V ~ 3.6V compatibility
• Operating Temperature: -40°C ~ 85°C range
• Package Footprint: 8-SOIC form factor with 0.154" width (3.90mm)
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The AT25XE011-SSHN-T meets all electrical and mechanical substitution criteria. Packaging format differs (Tape & Reel versus Tube), but this represents a supply chain variation rather than a functional incompatibility. Both parts share identical pin configurations, voltage specifications, temperature ratings, and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25DF011-SSHN-B and AT25XE011-SSHN-T are active production parts from Renesas Electronics Corporation with identical ROHS3 compliance and MSL Level 1 ratings. The parts are electrically and mechanically interchangeable at the PCB level. The primary distinction is packaging format: the main part is supplied in Tube packaging while the substitute is supplied in Tape & Reel format. This difference affects procurement and assembly processes but does not impact functional performance or reliability in the application circuit.

Write cycle timing shows minor variations (word write: 8µs versus 12µs; page write: 4.6ms versus 3ms), which remain within acceptable tolerances for most SPI FLASH memory applications. System designers should confirm that application timing requirements accommodate these specifications.

Frequently Asked Questions (FAQ)

Q: Are AT25DF011-SSHN-B and AT25XE011-SSHN-T pin-compatible?

A: Yes. Both parts use the 8-SOIC package with identical pin assignments and electrical characteristics. Direct PCB substitution is supported without circuit modification.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous carrier tape for automated assembly processes. Electrical and mechanical specifications are identical; the difference is supply chain format only.

Q: Do the write cycle time differences affect compatibility?

A: The AT25XE011-SSHN-T has slightly longer word write times (12µs versus 8µs) and slightly shorter page write times (3ms versus 4.6ms). Applications must confirm that firmware and timing loops accommodate these specifications. For most standard SPI FLASH implementations, these variations are within acceptable operating margins.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both AT25DF011-SSHN-B and AT25XE011-SSHN-T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use AT25XE011-SSHN-T as a direct replacement in production?

A: Yes, provided your supply chain and assembly process support Tape & Reel packaging format. Electrical and mechanical compatibility is confirmed. Verify that your automated assembly equipment is configured for the Tape & Reel format if transitioning from Tube packaging.
