Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT25DF011-SSHNGU-B is based on strict equivalence of the following critical parameters:

• Memory capacity: 1Mbit
• Memory organization: 128K x 8
• Interface protocol: SPI
• Operating frequency: 104 MHz
• Supply voltage range: 1.65V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Package footprint: 8-SOIC (0.154", 3.90mm Width)
• Compliance standards: ROHS3, REACH Unaffected

The AT25XE011-SSHN-T meets all functional and electrical requirements for direct substitution. The primary difference is packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share identical electrical specifications and pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25DF011-SSHNGU-B and AT25XE011-SSHN-T are active production parts from Renesas Electronics Corporation with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on:

1. Packaging requirements: Choose Tube format for manual assembly or small-volume applications; select Tape & Reel format for automated pick-and-place assembly or high-volume production.

2. Write cycle performance: The AT25DF011-SSHNGU-B offers faster word write cycles (8µs vs. 12µs), while the AT25XE011-SSHN-T provides faster page write cycles (3ms vs. 4.6ms). Evaluate application timing requirements to determine which specification is critical.

3. Inventory availability: The AT25XE011-SSHN-T currently has higher stock availability (3723 units vs. 1100 units).

Both parts are electrically and mechanically compatible for direct substitution in 8-SOIC surface mount applications requiring 1Mbit SPI FLASH memory.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts use the 8-SOIC package with identical pinout and electrical interface specifications. They are direct pin-for-pin substitutes.

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

A: Tube packaging is suitable for manual handling and small-quantity applications. Tape & Reel packaging is designed for automated assembly equipment and high-volume production runs. The electrical and functional specifications of the components are identical.

Q: Can I use AT25XE011-SSHN-T as a drop-in replacement for AT25DF011-SSHNGU-B?

A: Yes, for applications where write cycle timing is not a critical constraint. Both parts meet the same electrical specifications, voltage range, temperature range, and interface requirements. Verify that the slightly different write cycle times (word: 8µs vs. 12µs; page: 3ms vs. 4.6ms) are acceptable for your application.

Q: Are both parts RoHS compliant?

A: Yes. Both AT25DF011-SSHNGU-B and AT25XE011-SSHN-T are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
