Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25DF011-SSHN-T is determined by strict equivalence in the following parameters:

• Memory capacity: 1Mbit
• Memory organization: 128K x 8 bit configuration
• Interface protocol: SPI
• Clock frequency: 104 MHz operation
• Supply voltage compatibility: 1.65V ~ 3.6V range
• Operating temperature range: -40°C ~ 85°C
• Package form factor: 8-SOIC with 0.154" (3.90mm) width
• Surface mount compatibility
• RoHS3 compliance status

The AT25XE011-SSHN-T meets all substitution criteria within these parameters. Variations in write cycle timing do not affect substitution eligibility, as these are performance characteristics that remain within acceptable operational bounds for the specified interface and memory class.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25DF011-SSHN-T and AT25XE011-SSHN-T are active production devices from Renesas Electronics Corporation with identical RoHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and application-specific write cycle requirements. The AT25DF011-SSHN-T offers faster word write performance at 8µs, while the AT25XE011-SSHN-T provides faster page write performance at 3ms. Both devices maintain full electrical and mechanical compatibility within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can AT25XE011-SSHN-T be used as a direct replacement for AT25DF011-SSHN-T?

A: Yes. Both devices share identical memory capacity (1Mbit), organization (128K x 8), 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 form factor. No circuit modifications are required.

Q: What are the differences between these substitute parts?

A: The primary differences are write cycle times. AT25DF011-SSHN-T specifies 8µs word write and 4.6ms page write cycles. AT25XE011-SSHN-T specifies 12µs word write and 3ms page write cycles. These timing variations do not affect pin compatibility or functional operation within the SPI memory interface.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical 8-SOIC surface mount packaging with 0.154" (3.90mm) width, enabling use with the same pick-and-place equipment and reflow soldering profiles.

Q: Do these parts have the same compliance certifications?

A: Yes. Both AT25DF011-SSHN-T and AT25XE011-SSHN-T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected based on availability?

A: Selection should prioritize current inventory levels and project lead time requirements. AT25DF011-SSHN-T has 15,697 units in stock, while AT25XE011-SSHN-T has 3,723 units available. Both are active production parts from the same manufacturer.
