24LC04BHT-E/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC04BHT-E/MS is a 4Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial interface communication. This device operates at 400 kHz clock frequency with a 900 ns access time and supports supply voltages from 2.5V to 5.5V across an operating temperature range of -40°C to 125°C. The component is housed in an 8-MSOP surface mount package and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified when they maintain functional equivalence through matching memory capacity, interface protocol, package type, and critical electrical parameters while potentially offering enhanced performance characteristics or alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC04BHT-E/MS is determined by the following mandatory parameters:

Primary Matching Criteria:

• Memory capacity: 4Kbit
• Memory format: EEPROM technology
• Serial interface: I2C protocol
• Package type: 8-MSOP or 8-VSSOP (mechanically compatible)
• Mounting: Surface mount configuration

Secondary Compatibility Parameters:

• Supply voltage range must encompass or overlap with 2.5V ~ 5.5V
• Write cycle time: 5 ms (standard for this memory class)
• RoHS3 compliance status
• Operating temperature range must support minimum -40°C to 125°C or equivalent industrial specification

The identified substitute BR24G04FVM-3AGTTR from Rohm Semiconductor satisfies all primary matching criteria with enhanced clock frequency capability (1 MHz versus 400 kHz) and maintains functional compatibility through identical memory organization and I2C interface protocol.

Parameter Comparison

Engineering Selection Recommendations

Both the 24LC04BHT-E/MS and BR24G04FVM-3AGTTR maintain Active product status with full RoHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory compliance for industrial applications.

The BR24G04FVM-3AGTTR offers enhanced I2C clock frequency capability at 1 MHz compared to the 400 kHz specification of the primary part, enabling faster data transfer rates in applications where communication speed is not constrained by the original design specification. The substitute part extends supply voltage operation to 1.6V minimum, providing additional flexibility for low-power applications.

Package dimensions differ slightly between the two devices (0.118" versus 0.110" width), requiring verification of PCB layout constraints and solder reflow profile compatibility during implementation. Both components utilize identical 8-MSOP surface mount technology and maintain equivalent write cycle timing.

The operating temperature range of the substitute part extends to 85°C maximum versus 125°C for the primary part. Applications requiring full -40°C to 125°C operation must retain the 24LC04BHT-E/MS specification.

Frequently Asked Questions (FAQ)

Q: Can BR24G04FVM-3AGTTR directly replace 24LC04BHT-E/MS in existing designs?

A: Direct replacement is possible for applications operating within -40°C to 85°C temperature range and where I2C clock frequency of 1 MHz is compatible with system timing requirements. PCB layout verification is required due to minor package width differences (0.118" versus 0.110").

Q: What are the key differences between these two EEPROM devices?

A: The primary differences are clock frequency (400 kHz versus 1 MHz), maximum operating temperature (125°C versus 85°C), and minimum supply voltage (2.5V versus 1.6V). Memory capacity, interface protocol, write cycle time, and package type remain functionally equivalent.

Q: Are both parts suitable for industrial temperature applications?

A: The 24LC04BHT-E/MS supports the full industrial temperature range of -40°C to 125°C. The BR24G04FVM-3AGTTR is rated to -40°C to 85°C, limiting its use to commercial and extended industrial applications below 85°C.

Q: Do package dimension differences affect PCB compatibility?

A: Both devices use 8-MSOP surface mount packaging with compatible pin configurations. The width difference (0.118" versus 0.110") requires verification against PCB footprint specifications and solder reflow thermal profiles to ensure manufacturing compatibility.

Q: What compliance certifications apply to both parts?

A: Both the 24LC04BHT-E/MS and BR24G04FVM-3AGTTR maintain RoHS3 compliance, REACH unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compliance for industrial and commercial applications.
