Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17C010A-10JC is determined by the following critical parameters:

• Memory capacity (1Mb Serial EEPROM)
• Package type (20-PLCC with 9x9mm dimensions)
• Mounting configuration (Surface Mount, J-Lead)
• Functional compatibility (Serial EEPROM architecture)

The AT17LV010A-10JU qualifies as a substitute based on matching memory size, package footprint, and mounting type. While this substitute operates across an extended voltage range (3V ~ 3.6V, 4.5V ~ 5.5V) and temperature range (-40°C ~ 85°C), it maintains electrical and mechanical compatibility with the original part's 5V operating window and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV010A-10JU is the designated substitute for the obsolete AT17C010A-10JC. Selection of this alternative is supported by:

• Active product status, ensuring continued availability and manufacturing support
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Identical memory capacity and package specifications, enabling direct mechanical and electrical substitution
• Extended operating temperature range, providing broader application flexibility
• Dual voltage operation capability, including the original 5V specification window

Frequently Asked Questions (FAQ)

Q: Can the AT17LV010A-10JU be used as a direct replacement for the AT17C010A-10JC?

A: Yes. Both parts share identical memory capacity (1Mb), package type (20-PLCC, 9x9mm), and mounting configuration (Surface Mount, J-Lead). The substitute operates within the original part's 5V specification range and maintains full electrical compatibility.

Q: What are the key differences between these parts?

A: The AT17LV010A-10JU offers an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and dual voltage operation (3V to 3.6V and 4.5V to 5.5V). It also carries ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical MSL ratings.

Q: Does the substitute part require circuit modifications?

A: No circuit modifications are required. The AT17LV010A-10JU maintains pin-for-pin compatibility and operates within the original part's 5V supply voltage specification, enabling direct substitution in existing designs.

Q: What is the packaging difference between these parts?

A: Both parts use identical 20-PLCC (9x9mm) surface mount packages with J-Lead configuration. Packaging is functionally equivalent.

Q: Why is the original part obsolete?

A: The AT17C010A-10JC is classified as obsolete by the manufacturer. The AT17LV010A-10JU represents the current active alternative, offering improved compliance and extended operational specifications.
