Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC32AFT-I/MS are classified based on the following substitution criteria:

Direct Substitutes (Identical Electrical and Mechanical Parameters): Parts that maintain all key electrical parameters including 32Kbit memory capacity, I2C 400 kHz interface, 900 ns access time, 5ms write cycle time, 2.5V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 8-MSOP package configuration.

Manufacturer Recommended Substitutes (Extended Voltage or Temperature Range): Parts that exceed the minimum electrical specifications of the main part while maintaining core functionality. These include devices with lower minimum supply voltage (1.7V or 1.8V) or extended maximum operating temperature (125°C), providing broader application flexibility.

Parametric Equivalents (Same Core Specifications, Different Packaging): Parts with identical electrical characteristics but supplied in alternative packaging formats such as Cut Tape or Tube, enabling procurement flexibility without functional changes.

Cross-Manufacturer Alternatives (Different Manufacturer, Equivalent Specifications): Parts from alternative manufacturers such as Rohm Semiconductor that match the 32Kbit capacity, I2C interface, and package footprint, with consideration for product lifecycle status and verification status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): Select 24LC32AF-I/MS, 24LC32AT-I/MS, or 24LC32AFT-E/MS when identical electrical specifications and 8-MSOP package are required. These parts maintain the 2.5V to 5.5V supply voltage and -40°C to 85°C operating temperature range of the main part. The 24LC32AFT-E/MS provides extended temperature operation to 125°C if thermal margin is needed.

For Extended Supply Voltage Range: Select 24AA32AFT-I/MS (1.7V minimum) or 24AA32AT-I/MS (1.8V minimum) when applications require operation below 2.5V supply voltage. Both parts maintain all other electrical parameters and are available in active product status.

For Packaging Format Flexibility: Select 24LC32AF-I/MS for Tube packaging or 24AA32AFT-I/MS and 24AA32AT-I/MS for Cut Tape & Digi-Reel formats when procurement or assembly processes require alternative packaging configurations.

For Cross-Manufacturer Substitution: BR24G32FVJ-3GTE2 from Rohm Semiconductor provides 32Kbit I2C EEPROM functionality with extended supply voltage range (1.6V minimum). However, this part is designated "Not For New Designs" and should be used only for legacy system maintenance or when Microchip alternatives are unavailable.

BR24G32FVM-3AGTTR from Rohm Semiconductor operates at 1 MHz I2C frequency, exceeding the 400 kHz specification of the main part. This higher clock speed may not be compatible with systems designed for 400 kHz operation and should be evaluated for timing compatibility.

Frequently Asked Questions (FAQ)

Q: Can 24LC32AF-I/MS replace 24LC32AFT-I/MS directly? A: Yes. Both parts share identical electrical specifications (32Kbit, 400 kHz I2C, 900 ns access time, 2.5V to 5.5V supply, -40°C to 85°C operation) and 8-MSOP package. The difference is packaging format: 24LC32AF-I/MS is supplied in Tube while 24LC32AFT-I/MS is supplied in Tape & Reel.

Q: What is the difference between 24LC32AFT-I/MS and 24AA32AT-I/MS? A: The 24AA32AT-I/MS has a lower minimum supply voltage (1.8V versus 2.5V) and is supplied in Cut Tape & Digi-Reel format instead of Tape & Reel. All other electrical parameters including memory capacity, I2C frequency, and operating temperature range are identical.

Q: Is BR24G32FVJ-3GTE2 suitable for new designs? A: No. BR24G32FVJ-3GTE2 is designated "Not For New Designs" by the manufacturer. It should be used only for legacy system support or replacement applications where Microchip alternatives are unavailable.

Q: Can BR24G32FVM-3AGTTR operate at 400 kHz I2C frequency? A: BR24G32FVM-3AGTTR is specified for 1 MHz I2C operation. While I2C protocol allows operation at lower frequencies, this part is designed for higher-speed applications. Compatibility with 400 kHz systems requires verification of timing requirements and I2C controller capabilities.

Q: What is the advantage of 24LC32AFT-E/MS over 24LC32AFT-I/MS? A: The 24LC32AFT-E/MS extends the maximum operating temperature to 125°C compared to 85°C for the standard part. All other specifications remain identical. Select this variant for applications requiring higher thermal operating margins.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance status, ensuring compatibility with environmental and regulatory requirements.
