Equivalent & Substitute Parts for 24LC08BH-I/MS

Part Overview

The 24LC08BH-I/MS is an 8Kbit EEPROM memory IC manufactured by Microchip Technology, designed for I2C serial communication applications. 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. The component is housed in an 8-MSOP surface mount package and maintains active product status with ROHS3 compliance. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, higher clock frequency operation, or different packaging configurations while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC08BH-I/MS is determined by the following critical parameters: 8Kbit memory capacity, EEPROM technology, I2C interface protocol, 5 ms write cycle time, and surface mount packaging. Substitute parts must maintain these core specifications to ensure functional compatibility within existing circuit designs.

Two substitution categories are identified:

Parametric Equivalent (24LC08B-I/MS): Identical electrical and mechanical specifications with verified programmability status and higher inventory availability.

Manufacturer Recommended Alternatives (BR24G08FVJ-3AGTE2, BR24G08FVM-3AGTTR): Rohm Semiconductor parts offering enhanced clock frequency (1 MHz versus 400 kHz) and extended lower voltage support (1.6V minimum versus 2.5V minimum). These parts maintain 8Kbit capacity, I2C interface, and compatible packaging while providing performance headroom for timing-critical applications.

Parameter Comparison

Engineering Selection Recommendations

24LC08B-I/MS is the direct parametric equivalent for applications requiring identical electrical performance and Microchip Technology sourcing. This part maintains all specifications of the primary part with verified programmability status and superior inventory availability (13,841 units versus 1,172 units).

BR24G08FVM-3AGTTR is recommended for designs requiring identical 8-MSOP packaging with enhanced clock frequency capability (1 MHz). This Rohm Semiconductor part supports lower minimum supply voltage (1.6V) and provides performance margin for I2C bus timing requirements while maintaining surface mount compatibility.

BR24G08FVJ-3AGTE2 is suitable for applications where 8-TSSOP packaging is acceptable and 1 MHz clock frequency operation is required. This part offers the same voltage and temperature performance as the BR24G08FVM variant with alternative package geometry.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can 24LC08B-I/MS be used as a direct replacement for 24LC08BH-I/MS?

A: Yes. The 24LC08B-I/MS is a parametric equivalent with identical memory capacity (8Kbit), I2C interface, clock frequency (400 kHz), write cycle time (5 ms), voltage range (2.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and 8-MSOP package. Both parts are manufactured by Microchip Technology and maintain ROHS3 compliance.

Q: What is the primary difference between Microchip and Rohm substitute options?

A: Microchip 24LC08B-I/MS maintains identical electrical specifications. Rohm BR24G08 series parts (BR24G08FVM-3AGTTR and BR24G08FVJ-3AGTE2) offer enhanced I2C clock frequency (1 MHz versus 400 kHz) and extended lower voltage support (1.6V minimum versus 2.5V minimum). Both manufacturers provide ROHS3 compliant, active status products.

Q: Are the Rohm BR24G08 parts pin-compatible with the 24LC08BH-I/MS?

A: Both BR24G08 variants maintain 8-pin surface mount packages compatible with I2C EEPROM pinout standards. BR24G08FVM-3AGTTR uses 8-MSOP packaging (identical to the primary part). BR24G08FVJ-3AGTE2 uses 8-TSSOP packaging. Physical footprint verification is required for PCB layout compatibility.

Q: Can I use a 1 MHz clock frequency part in a 400 kHz I2C bus design?

A: Yes. The BR24G08 series parts rated for 1 MHz operation are backward compatible with 400 kHz I2C bus designs. Higher frequency capability does not prevent operation at lower bus speeds.

Q: What packaging formats are available for these parts?

A: 24LC08BH-I/MS and 24LC08B-I/MS are supplied in Tube packaging. BR24G08FVM-3AGTTR and BR24G08FVJ-3AGTE2 are supplied in Tape & Reel format. Packaging format selection depends on assembly process requirements and order quantity.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts (24LC08BH-I/MS, 24LC08B-I/MS, BR24G08FVJ-3AGTE2, BR24G08FVM-3AGTTR) maintain ROHS3 compliance and REACH unaffected status.
