Key Parameters

Substitute Part Grouping Explanation

Substitution was performed strictly based on identical or closely compatible parameter values crucial for EEPROM Memory IC applications. The key parameters considered are manufacturer, memory technology, format, size, organization, interface, supply voltage, operating temperature range, package specifications, and compliance attributes. Only verified parameters present in both the main part and substitute parts were compared.

Parameter Comparison

Engineering Selection Recommendations

Both the 24AA044-I/P and its substitute, 24AA04-I/P, are classified as Active and comply with ROHS3, REACH, MSL 1, and ECCN EAR99 certifications as specified. From a compliance and inventory status perspective, substitution can be determined strictly using these criteria. No differences exist in supply chain or regulatory statuses.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for choosing a substitute for the 24AA044-I/P EEPROM Memory IC?
A1: The main criteria are memory size, organization, interface type, supply voltage, operating temperature, package compatibility, and compliance certifications.

Q2: Are the 24AA044-I/P and 24AA04-I/P compatible in terms of package and mounting type?
A2: Both devices are provided in an 8-DIP (0.300", 7.62mm) through-hole package and use the 8-PDIP supplier device package.
