AT25DL161-SSHN-B Equivalent & Substitute Parts

Part Overview

The AT25DL161-SSHN-B is a 16Mbit FLASH memory IC manufactured by Renesas Electronics Corporation, designed for SPI interface applications operating at 100 MHz. This non-volatile memory device is packaged in 8-SOIC surface mount configuration and operates across the industrial temperature range of -40°C to 85°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same memory category, interface protocol, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25DL161-SSHN-B is determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Mbit
• Memory technology: FLASH (non-volatile)
• Interface protocol: SPI
• Operating frequency: 100 MHz
• Memory organization: 256 Bytes x 8192 pages
• Supply voltage range: 1.65V ~ 1.95V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SOIC surface mount
• Pin configuration: Identical mechanical and electrical pinout

The primary distinction between the main part and its substitute relates to packaging format (Tube versus Tape & Reel) and inventory availability, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

AT25DL161-SSHN-T is the primary substitute for AT25DL161-SSHN-B. Both parts are manufactured by Renesas Electronics, maintain identical electrical specifications, and are packaged in 8-SOIC surface mount configuration. The sole difference is packaging format: AT25DL161-SSHN-B is supplied in Tube packaging, while AT25DL161-SSHN-T is supplied in Tape & Reel format. Both parts carry Active product status and ROHS3 compliance. Selection between these two should be based on assembly process requirements and packaging handling procedures.

LE25S161MDTWG is not recommended as a substitute. This onsemi part carries Obsolete product status, and insufficient technical specifications are provided to confirm electrical and functional equivalence with the AT25DL161-SSHN-B. Obsolete parts present supply chain risk and should not be selected for new designs or ongoing production.

Frequently Asked Questions (FAQ)

Q: Can AT25DL161-SSHN-T be used as a direct replacement for AT25DL161-SSHN-B?

A: Yes. Both parts are electrically and functionally identical. The difference is packaging format only: Tube versus Tape & Reel. Substitution is valid provided your assembly process accommodates the Tape & Reel format.

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

A: Tube packaging supplies components in individual plastic tubes suitable for manual handling and small-volume assembly. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance.

Q: Is LE25S161MDTWG a viable alternative?

A: No. This part is marked Obsolete and lacks complete technical specifications necessary to confirm compatibility. Obsolete components present supply continuity risks and should not be used for new designs.

Q: What parameters must remain identical for substitution?

A: Memory capacity (16Mbit), memory format (FLASH), interface protocol (SPI), operating frequency (100 MHz), supply voltage range (1.65V–1.95V), operating temperature range (-40°C to 85°C), and 8-SOIC package configuration must all remain unchanged.

Q: Are there any compliance differences between the substitute parts?

A: No. Both AT25DL161-SSHN-B and AT25DL161-SSHN-T carry identical ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.
