24LC16BHT-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC16BHT-E/SN is a 16Kbit I2C EEPROM memory IC manufactured by Microchip Technology in 8-SOIC surface mount packaging. This non-volatile memory device operates at 400 kHz clock frequency with 900 ns access time and supports a supply voltage range of 2.5V to 5.5V across an operating temperature range of -40°C to 125°C. The device is ROHS3 compliant and currently in active production status with 896 units in stock.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives from different manufacturers that meet the same functional and electrical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC16BHT-E/SN is determined by the following critical parameters:

Core Functional Parameters:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8
• Interface protocol: I2C
• Clock frequency: 400 kHz minimum
• Access time: 900 ns or faster
• Write cycle time: 5ms or faster

Electrical Compatibility Parameters:

• Supply voltage range must encompass or be compatible with 2.5V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C minimum

Physical Compatibility Parameters:

• Package type: 8-SOIC or equivalent footprint (0.154" width or 3.90mm width)
• Mounting type: Surface mount

Compliance Requirements:

• ROHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and functional specifications) and manufacturer-recommended alternatives (functionally equivalent with minor specification variations that do not impact application compatibility).

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: The 24LC16BT-E/SN from Microchip Technology is a direct parametric equivalent with identical electrical specifications and functional performance. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). This substitute is suitable for applications where the packaging format change does not impact manufacturing processes. Inventory availability is significantly higher at 7550 units.

Manufacturer-Recommended Alternatives (Rohm Semiconductor): The BR24S16FJ-WE2 and BR24S16F-WE2 from Rohm Semiconductor are manufacturer-recommended alternatives. Both devices meet the core functional requirements with identical 16Kbit capacity, 2K x 8 organization, I2C interface, and 400 kHz clock frequency. Key considerations:

• BR24S16FJ-WE2 maintains the 0.154" (3.90mm) package width matching the main part
• BR24S16F-WE2 uses a wider 0.173" (4.40mm) package, requiring PCB layout verification
• Both support extended supply voltage range (1.7V ~ 5.5V) providing greater design flexibility
• Operating temperature range is limited to -40°C ~ 85°C, which is acceptable for non-automotive applications but not suitable for extended temperature requirements
• Rohm parts show highest inventory availability (49944 and 18890 units respectively)

Manufacturer-Recommended Alternative (STMicroelectronics): The M24C16-DRMN3TP/K from STMicroelectronics is a manufacturer-recommended alternative with enhanced performance specifications. This device features:

• Higher clock frequency (1 MHz versus 400 kHz), providing faster data transfer capability
• Faster access time (450 ns versus 900 ns)
• Faster write cycle time (4ms versus 5ms)
• Extended supply voltage range (1.7V ~ 5.5V)
• Full operating temperature range (-40°C ~ 125°C) matching the main part
• AEC-Q100 automotive qualification, suitable for automotive and industrial applications
• Identical 8-SOIC (0.154", 3.90mm) package footprint
• Highest inventory availability at 30300 units

Parametric Equivalent (onsemi): The CAV24C16WE-GT3 from onsemi is a parametric equivalent with identical electrical specifications to the main part:

• Matching 400 kHz clock frequency and 900 ns access time
• Identical 5ms write cycle time
• Matching supply voltage range (2.5V ~ 5.5V)
• Full operating temperature range (-40°C ~ 125°C)
• AEC-Q100 automotive qualification
• Identical 8-SOIC (0.154", 3.90mm) package footprint
• Lower inventory availability at 1360 units

All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use BR24S16F-WE2 as a direct replacement for 24LC16BHT-E/SN?

A: The BR24S16F-WE2 is functionally compatible but requires PCB layout verification. The package width differs (0.173" versus 0.154"), which may impact footprint compatibility depending on PCB design tolerances. The BR24S16FJ-WE2 is preferred if package width matching is required.

Q: What is the difference between 24LC16BT-E/SN and 24LC16BHT-E/SN?

A: Both parts are parametric equivalents from Microchip Technology with identical electrical and functional specifications. The difference is packaging format: 24LC16BT-E/SN uses Cut Tape & Digi-Reel® format while 24LC16BHT-E/SN uses Tape & Reel format. Selection depends on manufacturing equipment compatibility.

Q: Is M24C16-DRMN3TP/K suitable for my application if I need 400 kHz operation?

A: Yes. The M24C16-DRMN3TP/K operates at 1 MHz, which is backward compatible with 400 kHz I2C bus speeds. The device will function correctly on a 400 kHz bus. The higher clock frequency capability provides design flexibility for future upgrades without component replacement.

Q: Can I use CAV24C16WE-GT3 in automotive applications?

A: Yes. The CAV24C16WE-GT3 carries AEC-Q100 automotive qualification, making it suitable for automotive applications. It provides identical electrical specifications to the main part with added automotive-grade reliability assurance.

Q: What are the temperature range limitations for Rohm alternatives?

A: Both BR24S16FJ-WE2 and BR24S16F-WE2 operate from -40°C to 85°C, which is 40°C lower than the main part's upper limit of 125°C. These alternatives are suitable for commercial and industrial applications but not for extended temperature or high-temperature industrial environments requiring the full -40°C to 125°C range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard lead-free manufacturing processes and storage requirements.

Q: Which substitute offers the best inventory availability?

A: The BR24S16FJ-WE2 from Rohm Semiconductor offers the highest inventory availability at 49944 units, followed by M24C16-DRMN3TP/K at 30300 units. Both provide excellent supply security for production requirements.
