AT25DF011-SSHNGU-T Equivalent & Substitute Parts

Part Overview

The AT25DF011-SSHNGU-T 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 packaged in an 8-SOIC surface mount configuration. The part is currently in active production status with 735 units available in new original stock. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent functional specifications within the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25DF011-SSHNGU-T is determined by the following critical parameters:

• Memory Capacity & Organization: 1Mbit, 128K x 8 configuration
• Interface Protocol: SPI serial communication
• Clock Frequency: 104 MHz operation
• Supply Voltage: 1.65V ~ 3.6V compatibility
• Operating Temperature: -40°C ~ 85°C range
• Package & Pinout: 8-SOIC form factor with identical mechanical dimensions
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The AT25XE011-SSHN-T meets all substitution criteria within these parameters. Both parts share identical memory capacity, interface type, voltage specifications, temperature range, and physical packaging. Differences in write cycle timing do not preclude substitution when application timing requirements are compatible with the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25DF011-SSHNGU-T and AT25XE011-SSHN-T are active production parts from Renesas Electronics Corporation with ROHS3 compliance and MSL Level 1 ratings. Selection between these parts is based on application-specific write cycle timing requirements. The AT25DF011-SSHNGU-T provides faster word write performance at 8µs compared to the AT25XE011-SSHN-T at 12µs. The AT25XE011-SSHN-T offers faster page write performance at 3ms versus 4.6ms. Both parts maintain identical electrical specifications for supply voltage, operating temperature, memory capacity, and SPI interface operation. Pinout and package compatibility ensure direct substitution at the PCB assembly level.

Frequently Asked Questions (FAQ)

Q: Can AT25XE011-SSHN-T replace AT25DF011-SSHNGU-T in existing designs?

A: Yes. Both parts share identical memory capacity (1Mbit), interface protocol (SPI), clock frequency (104 MHz), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 8-SOIC package configuration. Direct PCB-level substitution is supported.

Q: What are the differences between these parts?

A: Write cycle timing differs. AT25DF011-SSHNGU-T specifies 8µs word write and 4.6ms page write cycles. AT25XE011-SSHN-T specifies 12µs word write and 3ms page write cycles. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both AT25DF011-SSHNGU-T and AT25XE011-SSHN-T are ROHS3 compliant with MSL Level 1 moisture sensitivity rating.

Q: Do these parts have identical pinouts?

A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm dimensions, ensuring identical pinout and mechanical compatibility.

Q: Which part should be selected for time-critical write operations?

A: Application timing requirements determine selection. AT25DF011-SSHNGU-T provides faster word write performance. AT25XE011-SSHN-T provides faster page write performance. Verify application write cycle timing specifications against each part's datasheet values.
