AT25DF011-XMHNGU-T Equivalent & Substitute Parts

Part Overview

The AT25DF011-XMHNGU-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 housed in an 8-TSSOP surface mount package. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address packaging availability, inventory requirements, and specific application timing parameters while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

All three parts maintain active production status with full RoHS3 compliance and identical electrical specifications for core memory functionality. Selection between AT25DF011-XMHNGU-T, AT25DF011-XMHN-T, and AT25XE011-XMHN-T should be based on:

Packaging Requirements: Choose AT25DF011-XMHN-T for cut tape or reel delivery formats, or AT25XE011-XMHN-T for tape and reel packaging when bulk quantities are required.

Write Cycle Timing: AT25DF011 variants (both XMHNGU-T and XMHN-T) specify 8µs word write and 4.6ms page write cycles. AT25XE011-XMHN-T specifies 12µs word write and 3ms page write cycles. Applications with strict write timing requirements must account for these differences.

Inventory Availability: Current stock levels vary across packaging formats. AT25DF011-XMHN-T offers 8043 units and AT25XE011-XMHN-T offers 8182 units in standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can AT25DF011-XMHN-T directly replace AT25DF011-XMHNGU-T?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: XMHNGU-T uses tube packaging while XMHN-T uses cut tape and Digi-Reel formats. Pin configuration, memory capacity, interface protocol, and operating parameters are identical.

Q: Is AT25XE011-XMHN-T compatible with designs specified for AT25DF011-XMHNGU-T?

A: Electrical and mechanical compatibility is maintained. However, write cycle timing differs: AT25XE011-XMHN-T specifies 12µs word write time versus 8µs for AT25DF011 variants. Applications performing sequential write operations must account for this timing difference in firmware or hardware timing calculations.

Q: What is the significance of the packaging format differences?

A: Packaging format affects supply chain logistics and assembly processes. Tube packaging (XMHNGU-T) suits lower-volume or manual assembly operations. Cut tape and Digi-Reel (XMHN-T) support automated pick-and-place assembly. Tape and Reel (AT25XE011-XMHN-T) is optimized for high-volume production. Functional performance is identical across all formats.

Q: Are all three parts RoHS3 compliant?

A: Yes. AT25DF011-XMHNGU-T, AT25DF011-XMHN-T, and AT25XE011-XMHN-T all carry ROHS3 compliance certification with unlimited moisture sensitivity rating (MSL 1).

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on matching memory capacity (1Mbit), organization (128K x 8), interface type (SPI), clock frequency (104 MHz), voltage range (1.65V ~ 3.6V), temperature range (-40°C ~ 85°C), package type (8-TSSOP), and compliance certifications. Write cycle timing and packaging delivery format are allowed to vary.
