Key Parameters

Substitute Part Grouping Explanation

Substitution for the S-24CS08ADP-1G is determined by the following critical parameters:

• Memory Capacity & Organization: Must be 8Kbit with 1K x 8 organization to maintain functional equivalence
• Interface Protocol: I2C interface is mandatory for system compatibility
• Package & Mounting: 8-DIP through-hole package with 0.300" (7.62mm) pitch ensures mechanical and electrical compatibility
• Voltage Supply Range: Must encompass or be compatible with the 1.8V ~ 5.5V operating range
• Operating Temperature: Must support -40°C ~ 85°C range for equivalent thermal performance
• Memory Type & Technology: Non-volatile EEPROM technology is required

The identified substitute parts AT24C08C-PUM and BR24G08-3 meet these core substitution criteria. Both components maintain identical memory capacity, organization, interface protocol, and package specifications while offering enhanced performance characteristics in clock frequency and access time.

Parameter Comparison

Engineering Selection Recommendations

AT24C08C-PUM is the primary substitute option. This component is manufactured by Microchip Technology with active product status, ensuring long-term availability and supply chain stability. It maintains full compatibility with the S-24CS08ADP-1G across all critical parameters while offering improved performance through higher clock frequency (1 MHz vs. 400 kHz) and faster access time (550 ns vs. 900 ns). The voltage supply range of 1.7V ~ 5.5V is compatible with the original specification. ROHS3 compliance and REACH unaffected status align with the original part's regulatory certifications.

BR24G08-3 is a secondary substitute option manufactured by Rohm Semiconductor. While this component meets all core substitution criteria and maintains identical memory capacity, organization, interface, and package specifications, it carries obsolete product status. The voltage supply range extends to 1.6V, providing broader low-voltage compatibility. This option is suitable for legacy system maintenance where supply continuity is available but not recommended for new designs requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can AT24C08C-PUM directly replace S-24CS08ADP-1G in existing designs?

A: Yes. Both components share identical memory capacity (8Kbit), organization (1K x 8), I2C interface protocol, 8-DIP package dimensions, and operating temperature range (-40°C ~ 85°C). The voltage supply ranges are compatible, with AT24C08C-PUM supporting 1.7V ~ 5.5V. The higher clock frequency and faster access time of AT24C08C-PUM represent performance improvements with no functional incompatibility.

Q: What are the performance differences between the main part and substitutes?

A: The S-24CS08ADP-1G operates at 400 kHz clock frequency with 900 ns access time and 10 ms write cycle time. Both AT24C08C-PUM and BR24G08-3 operate at 1 MHz clock frequency with 5 ms write cycle time, providing faster data access and write operations. AT24C08C-PUM specifies 550 ns access time. These improvements do not create compatibility issues in I2C-based systems.

Q: Are there packaging differences between these parts?

A: All three components use 8-DIP through-hole packaging with 0.300" (7.62mm) pitch. Physical dimensions and pin configurations are identical, ensuring direct mechanical compatibility on printed circuit boards.

Q: Which substitute should be selected for new designs?

A: AT24C08C-PUM is the recommended choice for new designs due to its active product status, ensuring availability and supply chain support. BR24G08-3, while functionally equivalent, carries obsolete status and should be reserved for legacy system maintenance only.

Q: Are regulatory certifications equivalent across all three parts?

A: Yes. All three components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
