Key Parameters

Substitute Part Grouping Explanation

The AT17LV002-10SU qualifies as a direct substitute based on the following critical parameters:

• Memory Capacity: Both devices provide 2MB storage, maintaining functional equivalence for configuration memory applications
• Package Compatibility: Identical 20-SOIC (0.295", 7.50mm Width) surface mount package enables direct PCB layout compatibility
• Programmable Type: Both are Serial EEPROM devices with identical programming interface requirements
• Voltage Supply: The substitute supports the original 3V ~ 3.6V range plus extended 4.5V ~ 5.5V operation
• Moisture Sensitivity Level: Both rated at MSL 3 (168 Hours), ensuring equivalent handling and storage requirements
• Regulatory Compliance: Both share identical ECCN and HTSUS classifications

The AT17LV002-10SU represents an active product with enhanced specifications, including extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV002-10SU is the designated substitute for the obsolete AT17N002-10SC. Selection of this alternative is justified by:

• Functional Equivalence: Identical memory capacity, package footprint, and Serial EEPROM programming interface ensure direct replacement capability
• Product Lifecycle: The substitute is an active product with ongoing manufacturer support, addressing the obsolescence status of the original part
• Regulatory Compliance: RoHS3 compliance of the substitute meets current environmental standards, whereas the original part does not
• Enhanced Operating Range: Extended temperature specification (-40°C ~ 85°C) provides broader application flexibility compared to the original 0°C ~ 70°C range
• Dual Voltage Support: The substitute accommodates both the original 3V ~ 3.6V range and extended 4.5V ~ 5.5V operation

Frequently Asked Questions (FAQ)

Q: Can the AT17LV002-10SU be used as a direct replacement in existing designs using AT17N002-10SC?

A: Yes. Both devices share identical package geometry (20-SOIC), memory capacity (2MB), and Serial EEPROM programming interface. PCB layout and firmware compatibility are maintained without modification.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), voltage supply flexibility (dual range support), and RoHS compliance status (RoHS3 compliant versus non-compliant).

Q: Are there any voltage compatibility concerns when substituting?

A: No. The AT17LV002-10SU supports the original 3V ~ 3.6V supply range as a subset of its broader 3V ~ 3.6V and 4.5V ~ 5.5V capability. Designs operating within the original voltage specification require no modification.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute's extended operating range (-40°C ~ 85°C) encompasses the original specification (0°C ~ 70°C). Designs operating within the original temperature limits experience no compatibility issues.

Q: Are the package and pinout configurations identical?

A: Yes. Both devices use the 20-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout configuration, enabling direct PCB footprint compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The AT17LV002-10SU meets RoHS3 environmental standards, whereas the AT17N002-10SC does not. For applications subject to RoHS requirements or environmental regulations, the substitute provides compliant sourcing.
