Key Parameters

Substitute Part Grouping Explanation

Substitution for the AT24C08-10PC-2.5 is determined by the following critical parameters: 8Kbit memory capacity, EEPROM non-volatile memory format, I2C serial interface, 8-DIP through-hole package, and compatible voltage supply range. The clock frequency of 400 kHz and access time of 900 ns establish the baseline performance specification.

Substitute parts are grouped into two categories:

MFR Recommended Substitutes: Parts that maintain full compatibility with the original specification while offering improved product status or compliance certifications.

Parametric Equivalents: Parts that meet the core functional requirements but may differ in secondary parameters such as operating temperature range or clock frequency, provided the primary electrical and mechanical characteristics remain compatible.

Parameter Comparison

Engineering Selection Recommendations

24LC08B-I/P is the primary recommended substitute. This part is manufactured by Microchip Technology with active product status, ROHS3 compliance, and verified programmability. It maintains identical electrical specifications for memory capacity, interface, clock frequency, and write cycle time. The extended operating temperature range (-40°C to 85°C) provides broader environmental coverage compared to the original part.

24LC08B/P serves as a parametric equivalent with active product status and ROHS3 compliance. It matches the original operating temperature range (0°C to 70°C) and all core electrical parameters. Higher inventory availability (5300 pcs) supports production continuity.

BR24G08-3 is classified as obsolete and should be avoided for new designs. While it maintains 8Kbit EEPROM capacity and I2C interface compatibility, its obsolete status and lack of verified programmability make it unsuitable as a long-term substitute despite its higher clock frequency (1 MHz) and lower minimum supply voltage (1.6V).

Frequently Asked Questions (FAQ)

Q: Can 24LC08B-I/P directly replace AT24C08-10PC-2.5 in existing designs?

A: Yes. Both parts share identical memory capacity (8Kbit), EEPROM format, I2C interface, 400 kHz clock frequency, 900 ns access time, 5ms write cycle time, and 8-DIP through-hole package. The 24LC08B-I/P operates across a wider temperature range and carries active product status with ROHS3 compliance.

Q: What is the difference between 24LC08B-I/P and 24LC08B/P?

A: Both are Microchip Technology EEPROM devices with identical electrical specifications and active product status. The primary difference is operating temperature range: 24LC08B-I/P operates from -40°C to 85°C, while 24LC08B/P operates from 0°C to 70°C. Select based on your application's thermal requirements.

Q: Why is BR24G08-3 listed if it is obsolete?

A: BR24G08-3 is included for reference as a parametric equivalent that meets core functional requirements (8Kbit EEPROM, I2C interface, 8-DIP package). However, its obsolete status and unverified programmability make it unsuitable for new production. Use 24LC08B-I/P or 24LC08B/P instead.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and electrical compatibility with existing PCB designs without layout modifications.

Q: Does the higher clock frequency of BR24G08-3 (1 MHz vs 400 kHz) provide an advantage?

A: The higher clock frequency does not provide functional advantage for this application. The original specification requires 400 kHz operation. BR24G08-3's obsolete status and unverified programmability outweigh any performance consideration.
