Substitute Part Grouping Explanation

Substitute parts for the 24LC16BH-I/MS are qualified based on the following core parameters that determine functional compatibility:

Memory capacity: 16Kbit with 2K x 8 organization
Interface protocol: I2C at 400 kHz clock frequency
Access time: 900 ns maximum
Write cycle time: 5ms
Package compatibility: 8-MSOP or 8-TSSOP surface mount packages
Supply voltage range: Minimum 2.5V operation required

Engineering Selection Recommendations

24AA16-I/MS is the primary MFR recommended substitute. This Microchip part maintains identical memory capacity, I2C interface, and access time specifications while offering extended lower supply voltage operation (1.7V minimum versus 2.5V). Active production status and higher inventory availability (1512 Pcs) support production continuity.

24LC16B-E/MS is an MFR recommended alternative with extended operating temperature range (-40°C to 125°C) compared to the base part (-40°C to 85°C). This part is suitable for applications requiring higher temperature operation while maintaining identical electrical specifications. Highest inventory level (2300 Pcs) ensures supply availability.

24LC16B-I/MS is a parametric equivalent offering identical electrical and thermal specifications to the main part. This variant provides an alternative sourcing option with substantial inventory (2000 Pcs).

BR24G16FVJ-3GTE2 is a Rohm Semiconductor equivalent with matching 16Kbit capacity and I2C interface. This part carries "Not For New Designs" status and is supplied in 8-TSSOP packaging (versus 8-MSOP). Selection of this part should be limited to legacy design maintenance or where 8-TSSOP package compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can 24AA16-I/MS replace 24LC16BH-I/MS in existing designs?

A: Yes. Both parts share identical memory capacity (16Kbit), I2C interface (400 kHz), access time (900 ns), and operating temperature range (-40°C to 85°C). The 24AA16-I/MS offers lower minimum supply voltage (1.7V versus 2.5V), making it compatible with designs operating at or above 2.5V.

Q: What is the difference between 24LC16B-E/MS and 24LC16BH-I/MS?

A: The primary difference is operating temperature range. The 24LC16B-E/MS supports -40°C to 125°C, while the 24LC16BH-I/MS supports -40°C to 85°C. All other electrical parameters (memory size, I2C clock, access time, supply voltage) are identical. Select 24LC16B-E/MS for applications requiring extended high-temperature operation.

Q: Is BR24G16FVJ-3GTE2 suitable for new designs?

A: No. This Rohm Semiconductor part carries "Not For New Designs" status. It should be used only for legacy design maintenance or where existing designs specifically require the 8-TSSOP package variant.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the main part.

Q: Does package type affect substitution compatibility?

A: Package type affects PCB layout and assembly compatibility. The 24LC16BH-I/MS, 24AA16-I/MS, 24LC16B-E/MS, and 24LC16B-I/MS use 8-MSOP packaging. The BR24G16FVJ-3GTE2 uses 8-TSSOP packaging. Both packages are surface mount with identical pin counts and I2C signal compatibility, but PCB footprints differ. Verify footprint compatibility before substitution.

Q: Which substitute offers the best supply availability?

A: The 24LC16B-E/MS offers the highest inventory level at 2300 Pcs, followed by 24AA16-I/MS at 1512 Pcs and 24LC16B-I/MS at 2000 Pcs.
