Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17C020-10JC is determined by the following critical parameters:

• Memory capacity: 2MB (must match exactly)
• Package type: 20-PLCC (9x9) with J-Lead configuration (physical and electrical compatibility)
• Programmable type: Serial EEPROM (functional equivalence)
• Manufacturer: Microchip Technology (same product family)

The AT17LV002-10JU qualifies as a substitute based on identical memory size, package configuration, and programmable architecture. This part maintains the same 20-PLCC footprint and serial EEPROM functionality while offering extended voltage and temperature operating ranges and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV002-10JU is the qualified substitute for the obsolete AT17C020-10JC. Selection of this alternative is supported by the following factors:

• Identical 2MB memory capacity and 20-PLCC package configuration ensure direct functional and physical compatibility
• Active product status provides supply chain continuity and availability
• ROHS3 compliance of the substitute addresses regulatory requirements not met by the original part
• Extended voltage operating range (3V ~ 3.6V, 4.5V ~ 5.5V) encompasses the original part's 4.75V ~ 5.25V specification
• Extended temperature range (-40°C ~ 85°C) exceeds the original part's 0°C ~ 70°C specification
• Identical MSL rating, ECCN, and HTSUS classification maintain handling and regulatory consistency

Frequently Asked Questions (FAQ)

Q: Can the AT17LV002-10JU be used as a direct replacement for the AT17C020-10JC?

A: Yes. Both parts share identical memory capacity (2MB), package configuration (20-PLCC), and serial EEPROM architecture. The substitute operates within the original part's voltage and temperature specifications while offering extended operating ranges.

Q: What are the key differences between these parts?

A: The AT17LV002-10JU is an active product with ROHS3 compliance, whereas the AT17C020-10JC is obsolete and RoHS non-compliant. The substitute supports dual voltage ranges (3V ~ 3.6V and 4.5V ~ 5.5V) compared to the original's single 4.75V ~ 5.25V range, and operates across a wider temperature window (-40°C ~ 85°C versus 0°C ~ 70°C).

Q: Are there any package or pinout differences?

A: No. Both parts use the 20-PLCC (9x9) package with J-Lead configuration. Physical and electrical compatibility is maintained.

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

A: Both the AT17C020-10JC and AT17LV002-10JU carry an MSL rating of 2 (1 Year), indicating identical moisture handling requirements.

Q: Does the substitute meet current regulatory standards?

A: The AT17LV002-10JU is ROHS3 compliant and REACH unaffected. The original AT17C020-10JC is RoHS non-compliant. The substitute addresses modern regulatory requirements.
