AT17C010-10JC Equivalent & Substitute Parts

Part Overview

The AT17C010-10JC is a Serial EEPROM memory integrated circuit manufactured by Microchip Technology with 1Mb storage capacity. This component is classified as obsolete, which necessitates identification of functionally compatible alternatives for new designs and ongoing system support. The part operates within a 4.75V to 5.25V supply voltage range and is housed in a 20-PLCC surface mount package. Due to its obsolete status, equivalent parts with extended availability and active product support are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17C010-10JC is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 20-PLCC (9x9) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Programmable Type: Serial EEPROM functionality must be maintained across all substitute candidates.

Voltage Supply Range: The substitute part must support operation within the 4.75V to 5.25V range specified for the original component, or provide overlapping voltage compatibility.

Memory Architecture: While memory capacity may differ, the serial interface protocol and pin configuration must remain compatible with system requirements.

The AT17LV002-10JU meets these substitution criteria through identical package specifications, matching programmable type, and extended voltage supply range that encompasses the original operating window.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV002-10JU is the designated substitute for the obsolete AT17C010-10JC based on the following engineering criteria:

Product Status: The substitute part maintains active product status with Microchip Technology, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Regulatory Compliance: The AT17LV002-10JU achieves ROHS3 compliance, meeting current environmental and regulatory requirements for electronic component procurement and deployment.

Voltage Compatibility: The substitute's dual voltage supply range (3V ~ 3.6V and 4.5V ~ 5.5V) encompasses the original 4.75V ~ 5.25V operating window, enabling direct substitution in 5V-based systems.

Package Equivalence: Identical 20-PLCC surface mount packaging ensures mechanical fit and electrical pin compatibility with existing PCB designs.

Expanded Operating Range: The extended temperature range (-40°C ~ 85°C) provides broader environmental operating capability compared to the original specification (0°C ~ 70°C).

Frequently Asked Questions (FAQ)

Q: Can the AT17LV002-10JU be used as a direct replacement for the AT17C010-10JC?

A: Yes. Both components share identical 20-PLCC package specifications, matching Serial EEPROM programmable type, and overlapping voltage supply ranges. The substitute's 4.5V ~ 5.5V range encompasses the original 4.75V ~ 5.25V specification.

Q: What is the primary advantage of substituting to the AT17LV002-10JU?

A: The substitute part is in active production status with extended availability, whereas the AT17C010-10JC is obsolete. Additionally, the AT17LV002-10JU provides ROHS3 compliance and expanded operating temperature range.

Q: Does the increased memory capacity (2MB vs 1Mb) affect compatibility?

A: Memory capacity increase does not affect pin-level compatibility or package fit. System firmware and software must be evaluated to determine if the additional capacity provides functional benefit.

Q: Are there any voltage supply considerations when substituting?

A: The AT17LV002-10JU supports dual voltage ranges (3V ~ 3.6V and 4.5V ~ 5.5V). For 5V systems using the original part, operation within the 4.5V ~ 5.5V range ensures full compatibility.

Q: What is the moisture sensitivity level for both parts?

A: Both the AT17C010-10JC and AT17LV002-10JU carry MSL 2 (1 Year) rating, indicating identical moisture handling and storage requirements.
