Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC04BH-I/P is determined by the following critical parameters: memory size (4Kbit), memory organization (256 x 8 x 2), I2C interface protocol, 400 kHz clock frequency, 900 ns access time, 5ms write cycle time, 8-DIP package configuration, and through-hole mounting type. All substitute parts must maintain identical values for these parameters to ensure functional and mechanical compatibility.

The 24LC04BH-I/P accepts supply voltages from 2.5V to 5.5V. Substitute parts may have different voltage supply ranges provided all other electrical and mechanical parameters remain constant. Product status and programmable verification attributes do not affect substitution eligibility but are documented for procurement and quality assurance purposes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—24LC04BH-I/P, 24AA04-I/P, and 24LC04B-I/P—are manufactured by Microchip Technology and maintain active production status. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The 24AA04-I/P offers an extended lower voltage supply range (1.7V ~ 5.5V) compared to the 24LC04BH-I/P (2.5V ~ 5.5V), making it suitable for low-power applications. The 24LC04B-I/P is verified as programmable through DiGi-Electronics, whereas the 24LC04BH-I/P and 24AA04-I/P are not verified for this attribute. Selection should be based on specific application voltage requirements and programmable verification status when required.

Frequently Asked Questions (FAQ)

Q: Can 24AA04-I/P replace 24LC04BH-I/P in all applications?

A: Yes, provided the application does not require the specific voltage supply range of 2.5V ~ 5.5V. The 24AA04-I/P operates at 1.7V ~ 5.5V, which is compatible with all circuits designed for the 24LC04BH-I/P. All other electrical and mechanical parameters are identical.

Q: What is the difference between 24LC04B-I/P and 24LC04BH-I/P?

A: The 24LC04B-I/P is verified as programmable through DiGi-Electronics, while the 24LC04BH-I/P is not verified for this attribute. All electrical specifications, memory organization, interface protocol, and package configuration are identical.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configurations, ensuring direct mechanical and electrical compatibility on printed circuit boards.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8542.32.0051) codes.

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

A: The 24AA04-I/P is the appropriate choice for applications requiring operation below 2.5V, as it supports supply voltages down to 1.7V while maintaining all other specifications identical to the 24LC04BH-I/P.
