Key Parameters

Substitute Part Grouping Explanation

The substitution logic is strictly based on identical manufacturer, equivalent memory type and size, matching memory organization, parallel interface, equal or faster access and write times, same voltage supply range, identical operating temperature, equivalent mounting type, and identical package/case dimensions. Environmental compliance and product status are included where provided. Substitution is valid only when all listed parameters are congruent between main and substitute parts.

Parameter Comparison

Engineering Selection Recommendations

When selecting substitute EEPROM memory ICs for the AT28C010-12JI, product status and environmental compliance must be considered. AT28C010-12JU is listed as "Active" and ROHS3 compliant, offering updated compliance over the main obsolete and RoHS non-compliant part. Both parts share identical electrical, mechanical, and interface specifications. All certifications provided (REACH, ECCN, HTSUS) are equivalent.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when substituting AT28C010-12JI?
A1: Substitute components must strictly match memory type, memory size and organization, interface, supply voltage range, access and write times, operating temperature, mounting type, and package dimensions.

Q2: Is AT28C010-12JU mechanically compatible with AT28C010-12JI?
A2: Both devices use the 32-LCC (J-Lead) package and 32-PLCC (13.97x11.43) supplier device package, making them mechanically interchangeable.

Q3: Are there any compliance differences between the main and substitute part?
A3: AT28C010-12JU is ROHS3 compliant, whereas AT28C010-12JI is RoHS non-compliant. Both are REACH unaffected and share ECCN and HTSUS classifications.

Q4: What is the significance of the product status field?
A4: "Obsolete" indicates the main part is discontinued. "Active" status for AT28C010-12JU means it is currently available for procurement and ongoing production.

Q5: Can the substitute AT28C010-12JU be directly placed on existing PCBs designed for AT28C010-12JI?
A5: Both parts have identical package and pinout specifications, so they are physically compatible for direct placement.
