Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC014-E/SN are grouped based on the following substitution criteria:

Primary Matching Parameters:

• Memory capacity: 1Kbit
• Memory organization: 128 x 8
• Interface protocol: I2C
• Package type: 8-SOIC or 8-SOP (mechanically compatible)
• Write cycle time: 5ms

Secondary Compatibility Factors:

• Clock frequency: 400 kHz (primary) or higher frequencies (1 MHz) with backward compatibility
• Voltage supply range: Must encompass or overlap with 2.5V ~ 5.5V
• Operating temperature: Must support -40°C minimum and 85°C or higher maximum
• Access time: Performance specification that may vary between substitutes

Substitutes are divided into two categories:

Category A - Direct Replacements (400 kHz I2C): Parts maintaining 400 kHz clock frequency with compatible voltage and temperature ranges.

Category B - Enhanced Performance Substitutes (1 MHz I2C): Parts operating at higher clock frequency (1 MHz) with reduced voltage supply range (1.7V ~ 3.6V) but maintaining core memory specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (8-SOIC 3.90mm Package):

The 24LC01B-E/SN from Microchip Technology provides the most direct substitution with identical package dimensions, voltage range (2.5V ~ 5.5V), and extended temperature range (-40°C ~ 125°C). This part carries verified programmable status and maintains 400 kHz I2C operation. The primary difference is increased access time (4.6 µs versus 900 ns), which does not affect functional compatibility in standard I2C applications.

The M24C01-RMN6TP from STMicroelectronics offers equivalent electrical performance with 900 ns access time matching the original part. This substitute operates across 1.8V ~ 5.5V supply range and -40°C ~ 85°C temperature range with verified programmable status. The reduced maximum operating temperature (85°C versus 125°C) must be evaluated against application requirements.

For Enhanced Performance or Extended Voltage Range:

The AT24C01D-SSHM-T and AT24C01D-SSHM-B from Microchip Technology operate at 1 MHz clock frequency with verified programmable status. These parts are suitable for applications requiring higher I2C bus speeds. The reduced voltage range (1.7V ~ 3.6V) and maximum operating temperature (85°C) must be confirmed compatible with system specifications.

For Alternative Package Consideration (8-SOP 4.40mm):

Rohm Semiconductor BR24 series parts (BR24A01AF-WLBH2, BR24A01AF-WME2, BR24G01F-3GTE2, BR24L01AF-WE2, BR24T01F-WE2) maintain 1Kbit capacity and 400 kHz I2C operation in 8-SOP packaging. The BR24L01AF-WE2 carries verified programmable status. These substitutes require PCB layout modification to accommodate the 4.40mm package width versus the original 3.90mm width. The BR24A01AF-WME2 includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 24LC014-E/SN with a part operating at 1 MHz instead of 400 kHz?

A: Yes. The AT24C01D-SSHM-T and AT24C01D-SSHM-B operate at 1 MHz and maintain full I2C protocol compatibility. Higher clock frequency provides backward compatibility with 400 kHz bus operation. Verify that your system voltage supply (1.7V ~ 3.6V for these parts) and maximum operating temperature (85°C) meet application requirements.

Q: What is the difference between 8-SOIC and 8-SOP packaging?

A: Both are 8-pin surface mount packages with different body widths. The original 24LC014-E/SN uses 8-SOIC with 3.90mm width. Rohm Semiconductor BR24 series substitutes use 8-SOP with 4.40mm width. This 0.50mm difference requires PCB layout modification and cannot be used as a direct drop-in replacement without board redesign.

Q: Which substitute part has the widest voltage supply range?

A: The BR24G01F-3GTE2 and BR24T01F-WE2 from Rohm Semiconductor operate across 1.6V ~ 5.5V, providing the widest lower voltage limit. The BR24L01AF-WE2 operates across 1.8V ~ 5.5V. These extended lower voltage ranges support low-power applications. Confirm compatibility with your system's minimum supply voltage specification.

Q: Is the 24LC01B-E/SN a direct replacement for the 24LC014-E/SN?

A: Yes, the 24LC01B-E/SN is a direct replacement. It maintains identical 8-SOIC packaging (3.90mm width), voltage range (2.5V ~ 5.5V), and extended temperature range (-40°C ~ 125°C). The access time increases from 900 ns to 4.6 µs, which does not affect I2C protocol compliance or functional operation in standard applications.

Q: What does "Programmable Status - Verified" mean?

A: Verified programmable status indicates that the part has been tested and confirmed to support in-circuit programming or reprogramming operations. Not Verified status means this capability has not been confirmed by the supplier. For applications requiring field programming, select parts with Verified status.

Q: Can I use the M24C01-RMN6TP if my application operates at 125°C?

A: No. The M24C01-RMN6TP maximum operating temperature is 85°C. The 24LC01B-E/SN supports -40°C ~ 125°C and is the appropriate choice for extended temperature applications. Verify all substitute parts against your application's maximum operating temperature requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the original 24LC014-E/SN specification. All parts are also REACH Unaffected and classified as EAR99 for export control purposes.
