Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24AA014H-I/MS is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory Size: 1Kbit (128 x 8 organization)
• Memory Interface: I2C protocol
• Memory Type: Non-Volatile EEPROM
• Write Cycle Time: 5ms
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package Type: 8-MSOP or 8-TSSOP (mechanically compatible)

Allowable Parameter Variations:

• Clock Frequency: 400 kHz or higher (backward compatible)
• Access Time: 900 ns or faster (performance enhancement acceptable)
• Voltage Supply Range: Must encompass or exceed 1.7V ~ 5.5V minimum requirement
• Packaging Format: Tube or Tape & Reel acceptable for equivalent functionality

The identified substitute parts meet these criteria while maintaining functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

24AA01-I/MS (Microchip Technology): This part maintains identical electrical specifications and Active product status. It is suitable for direct substitution where access time tolerance permits operation at 3500 ns instead of 900 ns. Both parts share Microchip Technology manufacturing and identical voltage/temperature operating ranges. MSL rating difference (2 vs. 1) requires consideration for moisture-sensitive storage environments.

BR24G01FVJ-3GTE2 (Rohm Semiconductor): This substitute operates at 400 kHz clock frequency with 8-TSSOP package configuration. Product status is classified as Not For New Designs, limiting its application to legacy system maintenance or replacement scenarios. Voltage supply range extends to 1.6V minimum, providing broader low-voltage compatibility. MSL rating of 1 offers superior moisture handling characteristics.

BR24G01FVM-3AGTTR (Rohm Semiconductor): This part features enhanced clock frequency operation at 1 MHz, providing performance headroom beyond the 400 kHz requirement. Active product status supports new design implementation. The 8-MSOP package matches the primary part's form factor. Voltage supply range of 1.6V ~ 5.5V encompasses the original specification. MSL rating of 1 ensures optimal moisture sensitivity performance.

Frequently Asked Questions (FAQ)

Q: Can 24AA01-I/MS replace 24AA014H-I/MS in all applications?

A: Yes, within the constraint that the application tolerates 3500 ns access time instead of 900 ns. Both parts share identical memory capacity, I2C interface, clock frequency, write cycle time, voltage range, and operating temperature. The primary difference is access time performance and MSL rating.

Q: What is the significance of the 8-TSSOP versus 8-MSOP package difference?

A: Both packages are surface-mount configurations with identical pin counts and I2C interface compatibility. The 8-TSSOP (Thin Shrink Small Outline Package) and 8-MSOP (Mini Small Outline Package) differ in physical dimensions. PCB layout and footprint design must accommodate the specific package type. Mechanical compatibility requires verification against board design specifications.

Q: Why is BR24G01FVJ-3GTE2 marked as "Not For New Designs"?

A: This product status indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. It remains available for existing system support and replacement applications. For new designs, BR24G01FVM-3AGTTR or 24AA01-I/MS are preferred alternatives.

Q: Does the 1 MHz clock frequency of BR24G01FVM-3AGTTR provide backward compatibility?

A: Yes. The 1 MHz clock frequency is a performance enhancement that operates at higher speed than the 400 kHz requirement. I2C protocol implementation ensures backward compatibility with 400 kHz bus operation. The part functions correctly on 400 kHz I2C buses while supporting faster operation when the bus is configured for 1 MHz.

Q: What is the impact of MSL rating differences between substitute parts?

A: MSL (Moisture Sensitivity Level) rating indicates moisture absorption characteristics during storage and handling. MSL 1 (Unlimited) permits indefinite storage without baking requirements. MSL 2 (1 Year) requires component baking before reflow soldering if storage exceeds one year. Selection depends on supply chain management practices and storage conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements equivalent to the primary part.
