Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC01BH-E/SN are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Memory Size: 1Kbit
• Memory Organization: 128 x 8
• Memory Interface: I2C
• Clock Frequency: 400 kHz
• Write Cycle Time: 5ms
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

Allowable Variations:

• Voltage Supply Range: Substitute parts may have extended or narrower ranges provided the main part's range (2.5V ~ 5.5V) is fully contained within or overlaps with the substitute's range
• Operating Temperature: Substitute parts may have different temperature ranges; the main part range (-40°C ~ 125°C) defines the operational envelope
• Access Time: Variations permitted as long as performance meets or exceeds the main part specification
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters align

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the main part 24LC01BH-E/SN.

24LC01B-E/SN (Microchip Technology): Direct Microchip equivalent with identical electrical specifications and temperature range. Differs only in access time specification (4.6 µs vs. 900 ns), which does not restrict substitution as the slower access time remains within acceptable performance parameters for I2C EEPROM applications.

M24C01-RMN6P (STMicroelectronics): Cross-manufacturer substitute with matching core electrical parameters. Voltage supply range extends to 1.8V minimum, providing broader low-voltage compatibility. Operating temperature range is narrower (-40°C ~ 85°C), which may restrict use in applications requiring operation above 85°C.

M24C01-RMN6TP (STMicroelectronics): Functionally equivalent to M24C01-RMN6P with identical electrical specifications. Packaging format differs (Cut Tape & Digi-Reel® vs. Bulk), affecting supply chain and handling considerations only.

Frequently Asked Questions (FAQ)

Q: Can 24LC01B-E/SN replace 24LC01BH-E/SN in all applications?

A: Yes. Both parts share identical memory capacity (1Kbit), interface protocol (I2C 400 kHz), write cycle time (5ms), voltage supply range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and 8-SOIC package specifications. The access time difference (4.6 µs vs. 900 ns) does not restrict substitution.

Q: What are the limitations when using STMicroelectronics M24C01 variants?

A: M24C01-RMN6P and M24C01-RMN6TP operate within a narrower temperature range (-40°C ~ 85°C) compared to the main part (-40°C ~ 125°C). Applications requiring operation above 85°C must use Microchip parts. Voltage supply range is extended to 1.8V minimum, which is compatible with the main part's 2.5V minimum specification.

Q: Are there packaging differences between substitute parts?

A: M24C01-RMN6P is supplied in Bulk packaging, while M24C01-RMN6TP uses Cut Tape & Digi-Reel® format. Both maintain identical 8-SOIC mechanical specifications. 24LC01B-E/SN is supplied in Tube packaging. Packaging format affects procurement and assembly handling but does not impact electrical or mechanical compatibility.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8542.32.0051, matching the main part's regulatory status.

Q: Can I use M24C01 parts in applications designed for 24LC01BH-E/SN?

A: Yes, provided the application operates within the temperature range -40°C ~ 85°C and voltage supply range 1.8V ~ 5.5V. If the application requires operation above 85°C, use Microchip 24LC01 variants instead.
