Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AT24C04D-SSHM-T is determined by the following critical parameters:

Core Functional Requirements:

• Memory capacity: 4Kbit
• Memory organization: 512 x 8
• Interface protocol: I2C
• Package type: 8-SOIC
• Mounting type: Surface Mount

Performance Parameters:

• Clock frequency: 1 MHz or lower (backward compatible)
• Access time: 450 ns or faster
• Write cycle time: 5 ms or faster
• Voltage supply range: Must encompass or exceed 1.7V ~ 3.6V

Compliance Requirements:

• RoHS3 compliance
• Operating temperature range: -40°C ~ 85°C minimum

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents: Parts maintaining 1 MHz clock frequency, 450 ns access time, and identical electrical specifications.

Category B - Compatible Alternatives: Parts with reduced clock frequency (400 kHz) or extended voltage ranges that maintain functional compatibility through I2C protocol standardization and identical memory organization.

Parameter Comparison

Engineering Selection Recommendations

M24C04-DRMN3TP/K (STMicroelectronics) is the primary direct substitute. This part maintains identical 1 MHz clock frequency and 450 ns access time specifications. It offers extended voltage supply range (1.7V ~ 5.5V) and extended operating temperature range (-40°C ~ 125°C), providing superior performance margins. The part carries AEC-Q100 automotive qualification, indicating rigorous reliability testing. RoHS3 compliance and identical 8-SOIC packaging ensure drop-in compatibility.

AT24CS04-SSHM-T (Microchip Technology) provides same-manufacturer continuity with identical 1 MHz clock frequency. The 550 ns access time represents a minor performance reduction but remains within acceptable I2C timing margins. Extended voltage supply range (1.7V ~ 5.5V) offers improved design flexibility. Identical packaging and RoHS3 compliance ensure mechanical and electrical compatibility.

M24C04-FMN6TP (STMicroelectronics) operates at reduced 400 kHz clock frequency with 900 ns access time. This part is suitable for applications where lower clock speeds are acceptable. Extended voltage supply range and RoHS3 compliance are maintained. DiGi-Electronics Programmable verification status indicates validated functionality.

BR24G04FJ-3GTE2 and BR24T04FJ-WE2 (Rohm Semiconductor) operate at 400 kHz clock frequency. These parts are compatible with I2C protocol but require system-level verification that reduced clock frequency meets application timing requirements. Extended voltage supply range (1.6V ~ 5.5V) provides broad compatibility.

CAT24C04WI-GT3 (Catalyst Semiconductor Inc.) lacks complete technical specification data in available documentation. Selection of this part requires direct manufacturer datasheet consultation to verify compatibility with voltage, temperature, and timing requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 kHz I2C EEPROM as a direct replacement for the 1 MHz AT24C04D-SSHM-T?

A: Yes, with system-level verification. I2C protocol supports multiple clock frequencies on the same bus. A 400 kHz device operates at reduced speed but maintains full functional compatibility. Verify that your application does not have strict timing requirements that mandate 1 MHz operation. The I2C master must be capable of operating at the lower frequency.

Q: What is the significance of the voltage supply range difference between AT24C04D-SSHM-T (1.7V ~ 3.6V) and substitute parts offering 1.7V ~ 5.5V?

A: The extended voltage range in substitute parts provides greater design flexibility and improved tolerance to supply voltage variations. The original part specification (1.7V ~ 3.6V) is more restrictive. Substitute parts with extended ranges are fully compatible with the original specification range and offer additional operational margin. This is a beneficial characteristic for system reliability.

Q: Are all substitute parts in 8-SOIC packaging identical in physical dimensions?

A: Yes. All parts listed use 8-SOIC (0.154", 3.90mm Width) packaging. Physical dimensions are standardized across manufacturers for this package type, ensuring PCB footprint compatibility and drop-in replacement capability.

Q: What does RoHS3 compliance mean for component substitution?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. All listed substitute parts carry RoHS3 compliance, ensuring regulatory equivalence and environmental compatibility with the original part.

Q: Does the M24C04-DRMN3TP/K automotive qualification (AEC-Q100) affect its use in non-automotive applications?

A: No. AEC-Q100 qualification indicates the part has undergone additional reliability testing beyond standard requirements. This qualification is beneficial for any application requiring high reliability. The part is fully compatible with non-automotive designs and offers superior reliability margins.

Q: How do I verify that a substitute part will work in my existing design?

A: Verify the following parameters match or exceed your design requirements: memory capacity (4Kbit), memory organization (512 x 8), I2C interface, clock frequency (1 MHz or lower), voltage supply range (encompasses your supply voltage), operating temperature range (encompasses your operating conditions), and 8-SOIC package type. Consult the substitute part datasheet for complete electrical specifications.
