Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C08N-10SC-2.7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Memory Size: 8Kbit
• Memory Organization: 1K x 8
• Memory Interface: I2C
• Clock Frequency: 400 kHz
• Write Cycle Time: 5ms
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compatible Parameter Ranges:

• Voltage Supply: Substitute must support minimum 2.7V operation
• Operating Temperature: Substitute must support minimum 0°C operation
• Access Time: 900 ns or faster

All identified substitute parts meet these mandatory requirements while offering extended operating ranges and improved compliance certifications compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: M24C08-RMN6TP

The M24C08-RMN6TP from STMicroelectronics is the optimal substitute for the AT24C08N-10SC-2.7. This part maintains identical memory specifications, I2C interface, and 900 ns access time while offering active product status, ROHS3 compliance, and extended operating temperature range (-40°C to 85°C). The part is verified as programmable and maintains 2.7V minimum supply voltage compatibility. High inventory availability (105,200 units) ensures supply continuity.

Secondary Recommendation: CAT24C08WI-G

The CAT24C08WI-G from Catalyst Semiconductor Inc. provides an alternative with active product status and ROHS3 compliance. This part extends the lower voltage limit to 1.7V and operating temperature to -40°C to 85°C. Inventory availability is substantial (4,415 units).

Alternative Options: Rohm Semiconductor BR24 Series

The BR24L08FJ-WE2, BR24S08FJ-WE2, BR24T08FJ-WE2, and BR24G08FJ-3GTE2 from Rohm Semiconductor are active alternatives with ROHS3 compliance and extended temperature ranges. These parts support the required 8Kbit I2C 400 kHz specification and 8-SOIC packaging. BR24L08FJ-WE2 and BR24S08FJ-WE2 are verified as programmable.

Not Recommended for New Designs:

M24C08-WMN6P and M24C08-WMN6TP carry "Not For New Designs" status despite ROHS3 compliance and active inventory. These parts have higher minimum voltage requirements (2.5V) compared to the original specification (2.7V minimum is acceptable, but 2.5V minimum is preferred for new applications).

Frequently Asked Questions (FAQ)

Q: Can I use any 8Kbit I2C EEPROM as a substitute?

A: No. The substitute must match specific parameters: 8Kbit capacity, 1K x 8 organization, I2C interface at 400 kHz, 5ms write cycle time, and 8-SOIC package. Additional parameters such as access time, voltage range, and temperature range must meet or exceed the original specifications.

Q: What is the difference between the Rohm BR24 variants (BR24L08, BR24S08, BR24T08, BR24G08)?

A: These variants differ in minimum supply voltage specifications. BR24G08FJ-3GTE2 and BR24T08FJ-WE2 support 1.6V minimum, BR24S08FJ-WE2 supports 1.7V minimum, and BR24L08FJ-WE2 supports 1.8V minimum. All meet the 2.7V requirement of the original part. Selection depends on your circuit's minimum voltage requirement.

Q: Is the 8-SOIC package identical across all substitutes?

A: Yes. All substitute parts use the 8-SOIC package with 0.154" (3.90mm) width, ensuring direct pin-compatible replacement on existing PCBs without layout modifications.

Q: Why is the AT24C08N-10SC-2.7 marked as obsolete?

A: Microchip Technology has discontinued this part number. Active alternatives from STMicroelectronics, Catalyst Semiconductor, and Rohm Semiconductor provide equivalent or superior functionality with current product support and compliance certifications.

Q: Can I substitute M24C08-WMN6TP for new designs?

A: No. This part carries "Not For New Designs" status. Use M24C08-RMN6TP instead, which is actively supported and offers identical specifications with better long-term availability.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original AT24C08N-10SC-2.7 is non-compliant; all active substitutes are ROHS3 compliant.

Q: Are there inventory concerns with any substitute?

A: M24C08-RMN6TP has the highest inventory (105,200 units), followed by M24C08-WMN6TP (60,184 units). All other active alternatives maintain adequate stock levels (1,087 to 7,700 units). The original part has 1,194 units remaining.
