24LC014H-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC014H-I/P is a 1Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for I2C serial communication applications. This non-volatile memory device operates at 1 MHz clock frequency with 400 ns access time, housed in an 8-DIP through-hole package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent memory capacity, interface protocol, package type, and operating voltage ranges align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC014H-I/P are qualified based on the following critical parameters:

Memory Capacity & Organization: All substitutes maintain 1Kbit capacity with 128 x 8 organization, ensuring direct functional equivalence in data storage applications.

Interface Protocol: All substitutes use I2C serial communication, maintaining protocol compatibility with existing circuit designs.

Package & Mounting: All substitutes are housed in 8-DIP through-hole packages with identical 0.300" (7.62mm) pitch, enabling direct socket compatibility.

Operating Voltage Range: Substitutes must support the application's supply voltage requirements. The 24LC014H-I/P operates from 2.5V to 5.5V; substitute 24AA01-I/P extends the lower range to 1.7V, while 24LC01B-I/P maintains the 2.5V minimum.

Temperature Range: All substitutes operate across the identical -40°C to 85°C temperature range.

Compliance & Status: All substitutes are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

24AA01-I/P: This substitute is suitable for applications requiring extended low-voltage operation down to 1.7V. The reduced clock frequency (400 kHz) and increased access time (3500 ns) are acceptable in non-time-critical applications. All compliance certifications match the primary part. This option provides maximum voltage flexibility for battery-powered or low-power designs.

24LC01B-I/P: This substitute maintains the same voltage supply range as the primary part (2.5V ~ 5.5V) while operating at reduced clock frequency (400 kHz) and increased access time (4.6 µs). All compliance certifications are equivalent. This option is suitable for applications where the lower clock frequency does not impact system performance.

Both substitutes are active products with verified programmability status and full RoHS3 compliance, making them suitable for production applications requiring equivalent 1Kbit I2C EEPROM functionality in 8-DIP packages.

Frequently Asked Questions (FAQ)

Q: Can 24AA01-I/P or 24LC01B-I/P be used as direct replacements for 24LC014H-I/P?

A: Yes, both parts are direct substitutes for socket compatibility and functional equivalence. All three devices share identical memory capacity (1Kbit), organization (128 x 8), I2C interface, 8-DIP package, and operating temperature range. The primary differences are clock frequency and access time, which do not affect pin compatibility or basic I2C protocol operation.

Q: What is the impact of reduced clock frequency in substitute parts?

A: The 24AA01-I/P and 24LC01B-I/P operate at 400 kHz compared to the 24LC014H-I/P's 1 MHz. This reduces data transfer speed but does not affect I2C protocol compatibility. Applications with timing-critical requirements should evaluate whether the lower clock frequency impacts system performance.

Q: Which substitute should be selected for low-voltage applications?

A: The 24AA01-I/P supports operation down to 1.7V, making it suitable for low-voltage designs. The 24LC014H-I/P and 24LC01B-I/P both require minimum 2.5V supply voltage.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts—24LC014H-I/P, 24AA01-I/P, and 24LC01B-I/P—are ROHS3 compliant with unlimited moisture sensitivity rating and REACH unaffected status.

Q: What is the difference between access time specifications (400 ns vs. 3500 ns vs. 4.6 µs)?

A: Access time represents the delay from address input to data output availability. The 24LC014H-I/P provides the fastest access at 400 ns, while both substitutes operate at approximately 3500 ns (4.6 µs). This difference is negligible in most I2C applications but should be considered in time-critical systems.
