Substitute Part Grouping Explanation

Substitution eligibility for the 24LC08BHT-I/SN is determined by the following critical parameters:

Memory capacity (8Kbit) and organization (256 x 8 x 4 or 1K x 8)
I2C interface with 400 kHz clock frequency
Access time of 900 ns
Write cycle time of 5 ms
Supply voltage range compatibility (minimum 2.5V)
8-SOIC package format
Surface mount technology
Operating temperature range (-40°C minimum, 85°C or higher maximum)

Substitute parts are grouped into three categories: direct packaging alternatives, manufacturer-recommended equivalents with extended specifications, and parametric equivalents from alternative manufacturers. All listed substitutes maintain electrical and mechanical compatibility within the specified parameter tolerances.

Engineering Selection Recommendations

For active production designs, select from Microchip Technology parts with Active product status: 24LC08BH-I/SN, 24AA08T-I/SN, 24LC08BT-E/SN, or 24LC08BT-I/SN. All are ROHS3 compliant and REACH unaffected.

The 24LC08BT-E/SN offers extended operating temperature range (-40°C ~ 125°C) compared to the primary part, suitable for high-temperature applications. The 24AA08T-I/SN provides lower minimum supply voltage (1.7V) for low-power applications.

The CAT24C208WI-GT3 from onsemi carries Obsolete product status and should not be selected for new designs. The M24C08-WMN6TP from STMicroelectronics is marked Not For New Designs and should be avoided for new product development.

Packaging format selection depends on assembly requirements: Tape & Reel for high-volume automated assembly, Cut Tape & Digi-Reel for mixed-volume production, and Tube for lower-volume or manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can 24LC08BT-I/SN replace 24LC08BHT-I/SN directly?

A: Yes. Both parts share identical electrical specifications (8Kbit, 400 kHz I2C, 900 ns access time, 2.5V ~ 5.5V supply, -40°C ~ 85°C operating range) and 8-SOIC package. The difference is packaging format: Tape & Reel versus Cut Tape & Digi-Reel. Electrical and mechanical compatibility is complete.

Q: What is the difference between 24LC08BT-E/SN and 24LC08BT-I/SN?

A: The 24LC08BT-E/SN operates across -40°C ~ 125°C, while 24LC08BT-I/SN operates across -40°C ~ 85°C. All other electrical parameters are identical. Select 24LC08BT-E/SN for applications requiring extended high-temperature operation.

Q: Why is CAT24C208WI-GT3 listed as Obsolete?

A: CAT24C208WI-GT3 carries Obsolete product status, indicating it is no longer manufactured. While electrically equivalent, it should not be selected for new designs due to limited availability and potential supply discontinuation.

Q: Can 24AA08T-I/SN be used in place of 24LC08BHT-I/SN?

A: Yes, with one advantage: 24AA08T-I/SN operates at lower minimum supply voltage (1.7V versus 2.5V). All other parameters match. This part is suitable for low-power applications requiring operation below 2.5V.

Q: Is M24C08-WMN6TP a suitable replacement?

A: M24C08-WMN6TP is electrically equivalent but carries Not For New Designs status from STMicroelectronics. It should not be selected for new product development. Use Microchip Technology or onsemi alternatives instead.

Q: What packaging format should I select?

A: Tape & Reel (24LC08BHT-I/SN) is standard for high-volume automated assembly. Cut Tape & Digi-Reel formats (24LC08BT-E/SN, 24LC08BT-I/SN, 24AA08T-I/SN) support mixed-volume production. Tube packaging (24LC08BH-I/SN) is used for lower-volume or manual assembly. All formats contain identical components; selection depends on assembly process requirements.
