Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT45DB161E-SHD-T is determined by strict alignment of the following critical parameters:

• Memory capacity: 16Mbit
• Memory technology: FLASH
• Interface protocol: SPI
• Clock frequency: 85 MHz
• Memory organization: 528 Bytes x 4096 pages
• Package type: 8-SOIC with 5.30mm width
• Supply voltage range: 2.5V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part AT45DB161E-SHD-T from Renesas Electronics Corporation meets all critical electrical and mechanical parameters. Variations in write cycle time for page operations (4ms versus 6ms) represent improved performance characteristics and do not preclude substitution. Both parts maintain identical pinout, package footprint, and functional interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AT45DB161E-SHD-T from Renesas Electronics Corporation is a direct substitute for the Microchip AT45DB161E-SHD-T. Both parts maintain identical electrical specifications, package geometry, and interface protocols. The Renesas variant demonstrates improved page write cycle performance (4ms versus 6ms), which represents a performance enhancement without introducing compatibility concerns.

The original Microchip part carries Obsolete product status, while the Renesas equivalent is classified as Not For New Designs. Both parts maintain ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on current inventory availability and supply chain considerations, as electrical and mechanical compatibility is fully established.

Frequently Asked Questions (FAQ)

Q: Can the Renesas AT45DB161E-SHD-T replace the Microchip AT45DB161E-SHD-T in existing designs?

A: Yes. Both parts share identical memory capacity, SPI interface, clock frequency, supply voltage range, operating temperature range, and 8-SOIC package footprint. Pin-to-pin compatibility is established.

Q: What is the significance of the different page write cycle times (6ms vs 4ms)?

A: The Renesas part achieves faster page write operations. This represents improved performance and does not create compatibility issues. Designs accommodating the original 6ms specification will function correctly with the faster 4ms variant.

Q: Are both parts suitable for new production designs?

A: The Microchip part is Obsolete; the Renesas part is Not For New Designs. For new production, alternative 16Mbit SPI FLASH memory devices with current product status should be evaluated.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both parts use 8-SOIC packaging with 0.209" (5.30mm) width, ensuring identical PCB layout compatibility.
