Key Parameters

Substitute Part Grouping Explanation

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

Package Compatibility: Both devices utilize the identical 20-SOIC (0.295", 7.50mm Width) surface mount package, ensuring mechanical and electrical pin compatibility without PCB redesign.

Memory Interface: Both components are Serial EEPROM devices from Microchip Technology, maintaining functional equivalence in configuration memory applications.

Voltage Supply Range: The AT17LV002-10SU supports 3V to 3.6V operation, which encompasses the original device's supply voltage specification. The substitute additionally supports 4.5V to 5.5V operation, providing extended voltage flexibility.

Operating Temperature: The substitute operates across -40°C to 85°C, which exceeds the original device's 0°C to 70°C range, offering broader environmental compatibility.

Memory Capacity: The AT17LV002-10SU provides 2Mb capacity, representing a functional upgrade from the 1Mb original specification while maintaining backward compatibility in applications not requiring the full expanded capacity.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV002-10SU is the designated substitute for the obsolete AT17N010-10SC based on product lifecycle status and regulatory compliance. The substitute maintains identical package geometry and pinout compatibility, eliminating PCB redesign requirements. The AT17LV002-10SU holds active product status with Microchip Technology, ensuring continued availability and manufacturing support.

The substitute achieves ROHS3 compliance, whereas the original device is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component procurement and environmental standards.

The expanded operating temperature range (-40°C to 85°C) and dual voltage supply capability (3V to 3.6V and 4.5V to 5.5V) of the substitute provide enhanced flexibility for diverse application environments compared to the original device's narrower specifications.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV002-10SU directly replace the AT17N010-10SC without PCB modifications?

A: Yes. Both devices share identical 20-SOIC package dimensions and pinout configuration, enabling direct substitution without circuit board redesign.

Q: What is the memory capacity difference between these devices?

A: The AT17N010-10SC provides 1Mb storage capacity, while the AT17LV002-10SU provides 2Mb capacity. The substitute's increased capacity is backward compatible with applications designed for the original 1Mb device.

Q: Are there voltage supply differences that affect circuit design?

A: The original device operates at 3V to 3.6V. The substitute supports both 3V to 3.6V and 4.5V to 5.5V ranges. Existing designs operating within the 3V to 3.6V window require no modification. The substitute's extended voltage range provides additional design flexibility for new implementations.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates ongoing manufacturing, quality assurance, and technical support from Microchip Technology. This ensures component availability, consistent supply chain access, and manufacturer backing for the substitute part.

Q: How do the RoHS compliance statuses differ?

A: The AT17N010-10SC is RoHS non-compliant, while the AT17LV002-10SU achieves ROHS3 compliance. ROHS3 compliance indicates the substitute meets current environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

Q: What is the Moisture Sensitivity Level difference?

A: The original device has MSL 1 (Unlimited moisture exposure tolerance), while the substitute has MSL 3 (168-hour moisture exposure limit). MSL 3 requires standard moisture control during storage and handling but does not impact operational performance in deployed applications.
