24LC16BHT-I/MS Equivalent & Substitute Parts

Part Overview

The 24LC16BHT-I/MS is a 16Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 900 ns access time. This device is housed in an 8-MSOP surface mount package and operates across a supply voltage range of 2.5V to 5.5V with an operating temperature range of -40°C to 85°C. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC16BHT-I/MS is determined by strict alignment of the following critical parameters: 16Kbit memory capacity, 2K x 8 organization, I2C interface protocol, 400 kHz clock frequency, 900 ns access time, and 5ms write cycle time. All substitute parts must maintain identical memory specifications and interface characteristics. Package compatibility includes both 8-MSOP and 8-TSSOP variants, as both are mechanically and electrically compatible within the specified footprint dimensions of 0.118" width and 3.00mm height. Voltage supply range and operating temperature range variations are permitted only when the substitute part range encompasses or matches the original specification. Surface mount mounting type is mandatory for all substitutes.

Engineering Selection Recommendations

For applications requiring direct replacement of the 24LC16BHT-I/MS, the 24LC16BT-I/MS and 24LC16BT-E/MS are preferred substitutes, as both maintain identical electrical specifications and Active product status. The 24LC16BT-I/MS provides parametric equivalence with matching voltage supply range and operating temperature specifications. The 24LC16BT-E/MS extends the operating temperature range to -40°C to 125°C, suitable for applications requiring enhanced thermal performance.

The 24AA16T-I/MS is a manufacturer-recommended substitute offering expanded voltage supply range (1.7V ~ 5.5V) while maintaining all core memory specifications. This part is suitable for low-voltage applications where the original 2.5V minimum is insufficient.

The BR24G16FVJ-3GTE2 from Rohm Semiconductor is a manufacturer-recommended alternative with compatible memory specifications and expanded voltage supply range (1.6V ~ 5.5V). However, this part carries a "Not For New Designs" product status, limiting its application to legacy system maintenance or inventory supplementation only. The 8-TSSOP package variant requires PCB layout verification for mechanical compatibility despite electrical equivalence.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 24AA16T-I/MS replace the 24LC16BHT-I/MS in all applications?

A: The 24AA16T-I/MS is electrically equivalent with identical memory specifications and I2C interface characteristics. The expanded voltage supply range (1.7V ~ 5.5V) provides broader operational flexibility. Direct substitution is supported for applications operating within the original 2.5V ~ 5.5V range. Applications requiring operation below 2.5V require design verification.

Q: What is the difference between 8-MSOP and 8-TSSOP packages?

A: Both packages are mechanically compatible within the specified footprint dimensions (0.118" width, 3.00mm height) and are electrically equivalent. PCB layout and solder reflow profiles may require minor adjustment due to package body geometry differences. Consult component datasheets for specific thermal and mechanical handling requirements.

Q: Why is the BR24G16FVJ-3GTE2 marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While electrically equivalent and suitable for legacy system maintenance, new product designs should prioritize Active status parts such as the 24LC16BT-I/MS or 24LC16BT-E/MS to ensure long-term availability and manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with environmental and hazardous substance restrictions.

Q: What determines whether a part is a valid substitute?

A: Valid substitutes must match the following parameters: 16Kbit memory capacity, 2K x 8 organization, I2C interface protocol, 400 kHz clock frequency, 5ms write cycle time, surface mount mounting type, and compatible package footprint. Voltage supply range and operating temperature range may vary provided the substitute range encompasses the original specification or meets specific application requirements.
