Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT28C010-15JC is determined by strict alignment of the following critical parameters:

• Memory capacity (1Mbit) and organization (128K x 8)
• Parallel interface architecture
• Access time specification (150 ns)
• Write cycle time (10ms)
• Supply voltage range (4.5V ~ 5.5V)
• Package type (32-PLCC with J-Lead configuration)
• Mounting method (Surface Mount)

The AT28C010-15JU qualifies as a direct substitute based on identical electrical specifications, memory architecture, and physical packaging. Differences in product status, operating temperature range, and compliance certifications do not affect functional interchangeability within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The AT28C010-15JU is functionally equivalent to the AT28C010-15JC for applications requiring 1Mbit parallel EEPROM memory with 150 ns access time in a 32-PLCC package. The substitute part maintains identical electrical and timing specifications, ensuring direct compatibility at the circuit level.

The AT28C010-15JU offers advantages in terms of product availability and compliance status. As an active product, it provides superior supply chain continuity compared to the obsolete AT28C010-15JC. The substitute part achieves ROHS3 compliance and supports an extended operating temperature range (-40°C to 85°C), providing greater flexibility for applications operating outside the original 0°C to 70°C specification.

Selection between these parts should be based on application requirements for temperature range, regulatory compliance, and supply chain considerations. Both parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are AT28C010-15JC and AT28C010-15JU pin-compatible?
