Equivalent & Substitute Parts for 24AA014H-I/P

Part Overview

The 24AA014H-I/P is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 900 ns access time. This component is designed for non-volatile data storage applications requiring low-voltage operation across 1.7V to 5.5V supply range. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent memory capacity, interface protocol, voltage specifications, and package configuration are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

The 24AA01-I/P qualifies as a direct substitute for the 24AA014H-I/P based on the following critical parameters:

Memory capacity, organization, and interface protocol remain identical (1Kbit, 128 x 8, I2C 400 kHz). Both devices operate within the same voltage supply range (1.7V ~ 5.5V) and temperature range (-40°C ~ 85°C). Package configuration, mounting type, and physical dimensions are equivalent (8-DIP, Through Hole, 0.300" spacing). Compliance certifications match across RoHS3, REACH, and moisture sensitivity specifications. The primary difference is access time specification: 24AA014H-I/P specifies 900 ns while 24AA01-I/P specifies 3500 ns. This variance does not prevent substitution in applications where the slower access time is acceptable within system timing requirements.

Parameter Comparison

Engineering Selection Recommendations

Both 24AA014H-I/P and 24AA01-I/P are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on access time requirements within the application circuit. The 24AA014H-I/P provides 900 ns access time, suitable for time-critical I2C read operations. The 24AA01-I/P provides 3500 ns access time and remains compatible with standard I2C protocol timing at 400 kHz clock frequency. Both devices maintain identical electrical characteristics for supply voltage, operating temperature, and write cycle performance. Package compatibility ensures direct PCB footprint interchangeability without layout modification.

Frequently Asked Questions (FAQ)

Q: Can 24AA01-I/P replace 24AA014H-I/P in existing designs?

A: Yes, provided the application timing requirements accommodate 3500 ns access time instead of 900 ns. I2C protocol operation at 400 kHz remains valid for both devices. PCB footprint and electrical interface are identical.

Q: What is the primary difference between these two parts?

A: Access time specification differs. 24AA014H-I/P specifies 900 ns; 24AA01-I/P specifies 3500 ns. All other electrical and mechanical parameters are equivalent.

Q: Are both parts available in the same package configuration?

A: Yes. Both devices use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pin assignments and physical dimensions.

Q: Do compliance certifications differ between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited).

Q: What supply voltage range do these devices support?

A: Both 24AA014H-I/P and 24AA01-I/P operate across 1.7V to 5.5V supply voltage range with identical operating temperature range of -40°C to 85°C.

Q: Are these parts pin-compatible?

A: Yes. Both devices use 8-DIP package with identical pin configuration, enabling direct socket substitution without circuit modification.
