Equivalent & Substitute Parts for 24LC08BHT-I/MS

Part Overview

The 24LC08BHT-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 device is packaged in 8-MSOP surface mount configuration and is currently in active production status with ROHS3 compliance. Alternative equivalent parts may be required due to inventory availability, packaging format preferences, or performance specification requirements in system design.

Substitute Part Grouping Explanation

Substitution of the 24LC08BHT-I/MS is determined by the following critical parameters: 8Kbit memory capacity, EEPROM non-volatile memory format, I2C serial interface, surface mount packaging in 8-pin configuration, and operating temperature range of -40°C to 85°C. The substitute parts are grouped into two categories based on allowed parameter variations:

Parametric Equivalent (Same Manufacturer): The 24LC08BT-I/MS from Microchip Technology maintains identical electrical specifications including 400 kHz clock frequency, 900 ns access time, and 2.5V to 5.5V supply voltage. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel).

Manufacturer Recommended Equivalents (Cross-Manufacturer): The BR24G08FVJ-3AGTE2 and BR24G08FVM-3AGTTR from Rohm Semiconductor provide functional equivalence with modified specifications. These parts maintain 8Kbit capacity, EEPROM format, I2C interface, and identical write cycle time. Allowable parameter variations include: clock frequency increased to 1 MHz (backward compatible with 400 kHz systems), supply voltage range expanded to 1.6V to 5.5V, and memory organization changed to 1K x 8. Package variations include 8-TSSOP-BJ and 8-MSOP configurations.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: The 24LC08BT-I/MS is the primary substitute for the 24LC08BHT-I/MS when identical electrical performance is required. Both devices are manufactured by Microchip Technology, maintain all core specifications including 400 kHz clock frequency and 900 ns access time, and are ROHS3 compliant with active product status. Selection between these parts depends solely on packaging format requirements: Tape & Reel for the 24LC08BHT-I/MS versus Cut Tape & Digi-Reel for the 24LC08BT-I/MS.

Cross-Manufacturer Alternatives: The BR24G08FVJ-3AGTE2 and BR24G08FVM-3AGTTR from Rohm Semiconductor are manufacturer-recommended equivalents suitable for applications where higher clock frequency (1 MHz) and extended low-voltage operation (1.6V minimum) provide system advantages. Both devices maintain ROHS3 compliance and active production status. The BR24G08FVJ-3AGTE2 is packaged in 8-TSSOP configuration, while the BR24G08FVM-3AGTTR uses 8-MSOP packaging matching the original device footprint.

Frequently Asked Questions (FAQ)

Q: Can the BR24G08FVM-3AGTTR replace the 24LC08BHT-I/MS in existing designs without modification?

A: The BR24G08FVM-3AGTTR is functionally compatible for I2C memory applications. Both devices use 8-MSOP packaging with identical pin assignments for I2C interface (SDA, SCL, WP, VSS, VCC). The higher clock frequency (1 MHz versus 400 kHz) is backward compatible with systems designed for 400 kHz operation. No circuit modifications are required for direct substitution.

Q: What is the difference between the 24LC08BT-I/MS and 24LC08BHT-I/MS?

A: These devices are electrically identical with all core parameters matching: 8Kbit capacity, 400 kHz I2C clock frequency, 900 ns access time, 2.5V to 5.5V supply voltage, and -40°C to 85°C operating temperature. The sole difference is packaging format: 24LC08BHT-I/MS is supplied in Tape & Reel format, while 24LC08BT-I/MS is supplied in Cut Tape & Digi-Reel format.

Q: Are the Rohm Semiconductor BR24G08 parts suitable for low-voltage applications below 2.5V?

A: Yes. The BR24G08FVJ-3AGTE2 and BR24G08FVM-3AGTTR support supply voltage down to 1.6V, extending operation below the 2.5V minimum of the Microchip 24LC08BHT-I/MS. This expanded voltage range makes Rohm parts suitable for battery-powered or low-power systems requiring operation at reduced supply levels.

Q: Does the package size difference between 8-MSOP and 8-TSSOP affect PCB layout?

A: Yes. The 24LC08BHT-I/MS and BR24G08FVM-3AGTTR both use 8-MSOP packaging (0.118" width, 3.00mm), allowing direct footprint compatibility. The BR24G08FVJ-3AGTE2 uses 8-TSSOP packaging (0.118" width, 3.00mm), which shares identical width but different pin pitch and body length. PCB layout modification is required when substituting with the 8-TSSOP variant.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts—24LC08BHT-I/MS, 24LC08BT-I/MS, BR24G08FVJ-3AGTE2, and BR24G08FVM-3AGTTR—are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.32.0051. All devices maintain active product status with unlimited moisture sensitivity level (MSL 1).
