Microchip 24VL014/SN EEPROM 1Kbit I2C Memory IC - Equivalent & Substitute Parts

Part Overview

The Microchip 24VL014/SN is a 1Kbit EEPROM memory IC with I2C interface operating at 400 kHz, packaged in 8-SOIC surface mount configuration. This non-volatile memory device is designed for applications requiring low-power data storage with I2C serial communication. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original packaging format (Tube) is unavailable, when higher clock frequency operation is required, or when alternative manufacturer sourcing is needed for supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24VL014/SN is determined by the following critical parameters:

Primary Compatibility Criteria:

• Memory Size: 1Kbit (128 x 8 organization)
• Memory Interface: I2C protocol
• Package Type: 8-SOIC or 8-SOP (mechanically compatible pin configurations)
• Mounting Type: Surface Mount

Secondary Compatibility Criteria:

• Clock Frequency: 400 kHz minimum (higher frequencies are backward compatible)
• Voltage Supply Range: Must encompass or exceed 1.5V ~ 3.6V
• Write Cycle Time: 5ms maximum
• Operating Temperature: Must support -20°C minimum and 85°C maximum

Substitute Categories:

Category A - Direct Microchip Equivalents (Same Manufacturer, Identical Electrical Specifications):

• 24VL014HT/SN: Identical specifications, Tape & Reel packaging
• AT24C01D-SSHM-T: Enhanced clock frequency (1 MHz), Cut Tape packaging
• AT24C01D-SSHM-B: Enhanced clock frequency (1 MHz), Bulk packaging

Category B - Cross-Manufacturer Alternatives (Rohm Semiconductor, Compatible Specifications):

• BR24T01F-WE2: 400 kHz operation, 8-SOP package
• BR24G01F-3GTE2: 400 kHz operation, 8-SOP package
• BR24L01AF-WE2: 400 kHz operation, 8-SOP package

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (8-SOIC Package): Select 24VL014HT/SN when Tape & Reel packaging is required instead of Tube format. This part maintains identical electrical specifications and operating parameters as the original 24VL014/SN.

For Enhanced Performance (Higher Clock Frequency): The AT24C01D series (AT24C01D-SSHM-T or AT24C01D-SSHM-B) operates at 1 MHz clock frequency with faster access time (4.5 µs), providing backward compatibility with 400 kHz I2C bus speeds. These parts extend the operating temperature range to -40°C and are verified as DiGi-Electronics programmable.

For Cross-Manufacturer Sourcing (Rohm Semiconductor): BR24T01F-WE2, BR24G01F-3GTE2, and BR24L01AF-WE2 provide equivalent 1Kbit I2C EEPROM functionality with 400 kHz operation. These parts use 8-SOP packaging (0.173", 4.40mm width) instead of 8-SOIC, requiring PCB layout verification. Rohm parts support extended voltage range (1.6V ~ 5.5V or 1.8V ~ 5.5V) and wider operating temperature (-40°C ~ 85°C).

Compliance Considerations: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status. MSL ratings vary: Microchip parts are MSL 1 (unlimited), while AT24C01D-SSHM-T is MSL 3 (168 hours). Rohm parts are MSL 1 (unlimited).

Frequently Asked Questions (FAQ)

Q: Can I use AT24C01D-SSHM-T as a direct replacement for 24VL014/SN? A: Yes, with design considerations. The AT24C01D-SSHM-T maintains 1Kbit capacity and I2C interface compatibility. The 1 MHz clock frequency is backward compatible with 400 kHz bus speeds. However, the minimum supply voltage is 1.7V (versus 1.5V for the original), and the package is 8-SOIC but with different MSL rating (MSL 3 vs MSL 1).

Q: What is the difference between 8-SOIC and 8-SOP packages? A: Both are 8-pin surface mount packages with identical pin counts and I2C signal assignments. The primary difference is package width: 8-SOIC is 0.154" (3.90mm) while 8-SOP is 0.173" (4.40mm). PCB footprints differ and are not interchangeable without layout modification.

Q: Are Rohm BR24 series parts compatible with Microchip 24VL014? A: Yes, functionally compatible. Both manufacturers' 1Kbit I2C EEPROM devices with 400 kHz operation meet the same electrical interface requirements. Package differences (8-SOP vs 8-SOIC) require PCB footprint verification. Rohm parts support wider voltage ranges (1.6V ~ 5.5V) and extended temperature operation (-40°C minimum).

Q: Which substitute has the highest inventory availability? A: BR24L01AF-WE2 (Rohm) has 28,200 pieces in stock, followed by AT24C01D-SSHM-T (Microchip) with 11,150 pieces.

Q: Can I substitute 24VL014/SN with 24VL014HT/SN without any design changes? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: 24VL014/SN is supplied in Tube, while 24VL014HT/SN is supplied in Tape & Reel. No PCB or firmware modifications are required.

Q: What are the key parameters that determine substitution eligibility? A: The critical parameters are: 1Kbit memory capacity, 128 x 8 organization, I2C interface protocol, 400 kHz minimum clock frequency, 5ms write cycle time, and 8-SOIC or 8-SOP surface mount package. Voltage supply range must support the application's operating voltage, and temperature range must encompass the system's thermal requirements.
