Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C01CT-I/MS is determined by the following critical parameters:

Core Functional Parameters (Must Match):

• Memory Size: 1Kbit
• Memory Organization: 128 x 8
• Memory Interface: I2C
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-MSOP or 8-TSSOP (mechanically compatible)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Clock Frequency: 400 kHz or higher (backward compatible)
• Voltage Supply Range: Equal to or wider than 4.5V ~ 5.5V
• Write Cycle Time: Equal to or faster than 1 ms
• Access Time: Equal to or faster than 900 ns
• Packaging Format: Tube, Tape & Reel, or alternative compatible packaging

Product Status Consideration:

• Active status preferred; Not For New Designs acceptable only for legacy applications

The following parts meet substitution criteria based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications): The 24C01C-I/MS is a direct substitute for the 24C01CT-I/MS, offering identical electrical and mechanical specifications with equivalent Active product status and RoHS3 compliance. Both parts are Microchip Technology products with matching 1Kbit capacity, 400 kHz I2C operation, and 8-MSOP packaging. Selection between these parts depends solely on packaging format availability (Tube vs. alternative formats).

Extended Voltage Range Substitutes: The 24LC014T-I/MS and 24LC01BT-I/MS both provide extended voltage supply ranges (2.5V ~ 5.5V) compared to the main part (4.5V ~ 5.5V), enabling operation in lower voltage applications. Both maintain 1Kbit capacity, 400 kHz I2C interface, and 8-MSOP packaging. These parts are supplied in Tape & Reel format and carry Active product status. Write cycle time increases to 5 ms, which is acceptable for non-time-critical applications.

Higher Clock Frequency Substitute: The BR24G01FVM-3AGTTR from Rohm Semiconductor operates at 1 MHz clock frequency, providing enhanced performance for applications requiring faster I2C communication. This part maintains 1Kbit capacity, 8-MSOP packaging, and Active product status with extended voltage range (1.6V ~ 5.5V). RoHS3 compliance and identical operating temperature range ensure regulatory and thermal compatibility.

Legacy Applications Only: The BR24G01FVJ-3GTE2 carries Not For New Designs status and should be used only in legacy or maintenance applications. While functionally equivalent in memory capacity and I2C interface, this Rohm Semiconductor part uses 8-TSSOP packaging (mechanically compatible with 8-MSOP) and extended voltage range (1.6V ~ 5.5V). New designs should prioritize Active status parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute 24LC014T-I/MS for 24C01CT-I/MS in my design? A: Yes. The 24LC014T-I/MS is functionally compatible, maintaining 1Kbit capacity and 400 kHz I2C operation in 8-MSOP packaging. The extended voltage range (2.5V ~ 5.5V) provides additional design flexibility. The increased write cycle time (5 ms vs. 1 ms) is acceptable unless your application requires faster write operations.

Q: What is the difference between 8-MSOP and 8-TSSOP packaging? A: Both are surface mount packages with 8 pins and compatible mechanical footprints (0.118" width, 3.00mm). The BR24G01FVJ-3GTE2 uses 8-TSSOP-BJ variant, which is mechanically interchangeable with 8-MSOP for PCB layout purposes.

Q: Why does BR24G01FVM-3AGTTR have 1 MHz clock frequency instead of 400 kHz? A: The BR24G01FVM-3AGTTR is designed for applications requiring faster I2C communication. The 1 MHz clock frequency is backward compatible with 400 kHz systems, as I2C devices operate at the lower negotiated speed. This part is suitable for high-speed I2C bus implementations.

Q: Is the BR24G01FVJ-3GTE2 suitable for new product designs? A: No. This part carries Not For New Designs status, indicating it is in end-of-life phase. For new designs, select from Active status parts: 24C01C-I/MS, 24LC014T-I/MS, 24LC01BT-I/MS, or BR24G01FVM-3AGTTR.

Q: What voltage range should I use for maximum compatibility? A: The 24C01CT-I/MS operates at 4.5V ~ 5.5V. If your application requires lower voltage operation, the 24LC014T-I/MS, 24LC01BT-I/MS, or BR24G01FVM-3AGTTR support 2.5V ~ 5.5V or 1.6V ~ 5.5V ranges respectively. Verify your power supply specifications before selection.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry RoHS3 Compliant status, ensuring compliance with hazardous substance restrictions for both new and legacy applications.
