24LC04BH-I/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC04BH-I/MS is a 4Kbit I2C EEPROM memory IC manufactured by Microchip Technology, designed for non-volatile data storage applications requiring serial communication. This device operates at 400 kHz clock frequency with 900 ns access time and is housed in an 8-MSOP surface mount package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are available from the same or alternative manufacturers, enabling design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC04BH-I/MS is determined by the following critical parameters: memory size (4Kbit), memory interface (I2C), package type (8-MSOP), and surface mount compatibility. Substitute parts are classified into two categories based on parameter alignment:

MFR Recommended Substitutes: Parts meeting all critical electrical parameters including memory size, interface type, and package specification. These parts maintain full functional equivalence within the specified operating conditions.

Parametric Equivalents: Parts with identical core memory specifications but differing in secondary parameters such as clock frequency, access time, or voltage supply range. These parts provide functional compatibility with potential performance or environmental trade-offs.

The following key parameters determine substitution validity:

• Memory Size: 4Kbit (mandatory)
• Memory Interface: I2C (mandatory)
• Package Type: 8-MSOP (mandatory)
• Mounting Type: Surface Mount (mandatory)
• Memory Organization: 256 x 8 x 2 or 512 x 8 (acceptable variation)

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for the 24LC04BH-I/MS should be based on the following engineering criteria:

Voltage Supply Compatibility: The main part operates within 2.5V ~ 5.5V. Substitute parts 24AA04-I/MS, 24AA044-I/MS, and BR24G04FVM-3AGTTR offer extended lower voltage support (1.7V or 1.6V minimum), providing broader supply range compatibility. Part 24LC04B-E/MS and 24LC04B-I/MS maintain the same 2.5V minimum specification.

Temperature Range: Part 24LC04B-E/MS extends the upper operating temperature to 125°C, compared to 85°C for the main part and other substitutes. This extended range is applicable for high-temperature environments.

Clock Frequency and Access Time: Parts 24AA044-I/MS and BR24G04FVM-3AGTTR operate at 1 MHz clock frequency with improved access times (400 ns), compared to the main part's 400 kHz and 900 ns specification. These parts provide enhanced performance for timing-critical applications.

Packaging and Compliance: All substitute parts maintain 8-MSOP surface mount packaging, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring mechanical and environmental compatibility.

Manufacturer Availability: Microchip Technology substitutes (24AA04-I/MS, 24AA044-I/MS, 24LC04B-E/MS, 24LC04B-I/MS) provide same-manufacturer continuity. Rohm Semiconductor alternative (BR24G04FVM-3AGTTR) offers cross-manufacturer substitution with equivalent I2C EEPROM functionality.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical memory size (4Kbit), clock frequency (400 kHz), access time (900 ns), and 8-MSOP package specification. The 24AA04-I/MS offers extended lower voltage support (1.7V minimum vs. 2.5V), making it compatible with a broader range of supply voltages while maintaining full functional equivalence.

Q: What is the difference between 24AA044-I/MS and the main part 24LC04BH-I/MS?

A: The 24AA044-I/MS operates at 1 MHz clock frequency with 400 ns access time, compared to the main part's 400 kHz and 900 ns specification. Both maintain 4Kbit memory size and 8-MSOP packaging. The higher clock frequency and faster access time make 24AA044-I/MS suitable for applications requiring improved performance, while maintaining I2C interface compatibility.

Q: Is 24LC04B-E/MS suitable for high-temperature applications?

A: Yes. The 24LC04B-E/MS extends the upper operating temperature to 125°C, compared to 85°C for the main part. All other electrical parameters remain identical, including 4Kbit memory size, 400 kHz clock frequency, and 8-MSOP package. This part is specified for extended temperature range environments.

Q: Can BR24G04FVM-3AGTTR from Rohm Semiconductor be used as a substitute?

A: Yes. The BR24G04FVM-3AGTTR maintains 4Kbit memory size, I2C interface, and 8-MSOP package compatibility. It operates at 1 MHz clock frequency with extended lower voltage support (1.6V minimum). The primary difference is the alternative manufacturer (Rohm Semiconductor vs. Microchip Technology) and the memory organization (512 x 8 vs. 256 x 8 x 2), which does not affect functional equivalence for I2C EEPROM applications.

Q: What packaging format is used for these parts?

A: All listed parts use 8-MSOP (8-pin Micro Small Outline Package) with 0.118" width (3.00mm for Microchip parts, 2.80mm for Rohm part). This is a surface mount package suitable for automated assembly. Microchip parts are available in Tube packaging, while BR24G04FVM-3AGTTR is supplied in Tape & Reel format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring environmental and regulatory compatibility with the main part specification.
