24AA02HT-I/LT EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24AA02HT-I/LT is a 2Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial communication. This device operates across a wide supply voltage range of 1.7V to 5.5V and maintains active product status with full RoHS3 compliance. Alternative part numbers become necessary when addressing supply chain constraints, inventory availability, or specific packaging preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 24AA02T-I/LT qualifies as a parametric equivalent to the 24AA02HT-I/LT based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

Memory capacity and organization (2Kbit, 256 x 8 configuration), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), supply voltage range (1.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), package designation (SC-70-5), and compliance certifications (ROHS3, REACH Unaffected). Both parts share identical base product number 24AA02 and maintain active product status with equivalent inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both the 24AA02HT-I/LT and 24AA02T-I/LT maintain active product status with full regulatory compliance. Selection between these parts is determined by inventory availability and supply chain considerations rather than technical differentiation. The 24AA02T-I/LT currently maintains higher inventory levels (3800 Pcs versus 3400 Pcs), making it suitable for high-volume procurement scenarios. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and consumer applications. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can 24AA02T-I/LT replace 24AA02HT-I/LT in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, memory capacity, I2C interface characteristics, timing parameters, supply voltage range, operating temperature range, and package designation (SC-70-5). No circuit modifications are required.

Q: Are there any differences in compliance or certifications?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental requirements are equivalent.

Q: What determines substitution eligibility for these parts?

A: Substitution is based on matching memory size (2Kbit), memory organization (256 x 8), I2C interface protocol, clock frequency (400 kHz), access time (900 ns), write cycle time (5ms), supply voltage range (1.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (SC-70-5). All parameters are identical between these parts.

Q: Are there packaging differences between these part numbers?

A: No. Both parts use identical 5-TSSOP, SC-70-5, SOT-353 package designation with surface mount mounting type. Physical footprint and pin configuration are identical.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability, supplier lead times, or existing supply agreements. Both maintain active product status with equivalent long-term availability.
