Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC16BT-I/MS are qualified based on the following critical parameters that determine functional compatibility:

Core Substitution Criteria:

• Memory capacity: 16Kbit (2K x 8 organization)
• Interface protocol: I2C at 400 kHz
• Access time: 900 ns maximum
• Write cycle time: 5ms
• Package: 8-MSOP or 8-TSSOP (mechanically compatible)
• Mounting: Surface mount
• RoHS compliance: ROHS3 Compliant

Voltage Supply Compatibility: Substitute parts must support the minimum 2.5V supply requirement of the main part. Parts with extended lower voltage ranges (1.7V or 1.6V minimum) are compatible as they encompass the 2.5V ~ 5.5V operating window.

Temperature Range Consideration: The main part operates -40°C to 85°C. Substitute parts with equal or extended temperature ranges maintain full compatibility.

Packaging Variance: Both 8-MSOP and 8-TSSOP packages are mechanically and electrically compatible within the specified dimensions (0.118", 3.00mm width).

Parameter Comparison

Engineering Selection Recommendations

24LC16B-I/MS (Microchip Technology): Direct functional equivalent with identical electrical specifications and 8-MSOP package. Differs only in packaging format (Tube vs. Tape & Reel). Suitable for applications where packaging format flexibility is acceptable. Active product status with ROHS3 compliance maintained.

24AA16T-I/MS (Microchip Technology): Manufacturer-recommended substitute with extended lower voltage range (1.7V minimum vs. 2.5V minimum). Fully compatible with 24LC16BT-I/MS supply requirements. Tape & Reel packaging matches the main part. Active product status. MSL rating of 2 (1 Year) versus MSL 1 (Unlimited) for the main part requires consideration in moisture-sensitive storage environments.

24LC16BT-E/MS (Microchip Technology): Manufacturer-recommended substitute with extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). Identical electrical and package specifications. Active product status with ROHS3 compliance. Suitable for applications requiring higher temperature operation margin.

BR24G16FVJ-3GTE2 (Rohm Semiconductor): Cross-manufacturer substitute with 8-TSSOP package (mechanically compatible with 8-MSOP). Extended lower voltage range (1.6V minimum). Carries "Not For New Designs" product status, indicating end-of-life trajectory. Use only in legacy system maintenance or when supply of Microchip alternatives is unavailable. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can 24LC16B-I/MS replace 24LC16BT-I/MS directly? A: Yes. Both parts share identical electrical specifications, memory capacity, interface, and package type. The only difference is packaging format (Tube vs. Tape & Reel). Verify your assembly process accommodates the tube format.

Q: What is the difference between 24LC16BT-I/MS and 24AA16T-I/MS? A: The 24AA16T-I/MS has a lower minimum supply voltage (1.7V vs. 2.5V) and different MSL rating (2 vs. 1). All other electrical parameters and memory specifications are identical. The 24AA16T-I/MS is suitable for low-power applications and is fully compatible with 2.5V ~ 5.5V systems.

Q: Why is 24LC16BT-E/MS listed as a substitute if it has a different temperature range? A: The 24LC16BT-E/MS extends the upper operating temperature to 125°C while maintaining all other specifications. It is a direct functional substitute for applications operating within -40°C to 85°C and provides additional thermal margin for designs requiring higher temperature capability.

Q: Is BR24G16FVJ-3GTE2 recommended for new designs? A: No. This part carries "Not For New Designs" status, indicating manufacturer end-of-life planning. Use only for legacy system support or when Microchip alternatives are unavailable. For new designs, select from active Microchip Technology options.

Q: Are 8-MSOP and 8-TSSOP packages interchangeable? A: Both packages are mechanically and electrically compatible within the specified dimensions (0.118", 3.00mm width). Verify PCB footprint compatibility with your design before substitution. Pin assignments remain identical across both package types.

Q: What does MSL rating mean for EEPROM selection? A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. MSL 1 (Unlimited) allows indefinite storage without baking. MSL 2 (1 Year) requires baking if stored beyond one year in standard conditions. Select based on your supply chain and storage practices.

Q: Can I use 24AA16T-I/MS in a 2.5V system? A: Yes. The 24AA16T-I/MS operates across 1.7V ~ 5.5V, which encompasses the 2.5V ~ 5.5V range of the main part. It is fully compatible with 2.5V supply systems.
