24LC024H-E/ST EEPROM Equivalent & Substitute Parts

Part Overview

The 24LC024H-E/ST is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, housed in an 8-TSSOP surface mount package. This non-volatile memory device operates at 1 MHz clock frequency with 400 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 2300 units in stock.

Equivalent and substitute parts are identified when they maintain functional compatibility through matching memory capacity (2Kbit), memory organization (256 x 8), I2C interface protocol, identical package form factor (8-TSSOP), and compatible electrical operating parameters. Substitutes may vary in clock frequency, access time, voltage supply range, and operating temperature specifications while maintaining core functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 24LC024H-E/ST is determined by the following mandatory parameters:

• Memory capacity of 2Kbit with 256 x 8 organization
• I2C serial interface protocol
• 8-TSSOP surface mount package form factor (0.173", 4.40mm Width)
• Non-volatile EEPROM technology
• ROHS3 compliance

Substitute parts may differ in the following parameters without affecting functional compatibility:

• Clock frequency (1 MHz vs. 400 kHz)
• Access time (400 ns, 450 ns, or 900 ns)
• Write cycle time (4ms or 5ms)
• Voltage supply range (minimum 1.6V to 2.5V; maximum 5.5V)
• Operating temperature range (-40°C to 85°C, 105°C, or 125°C)
• Manufacturer and base product number
• Packaging format (Tape & Reel vs. Cut Tape)

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes with Identical Performance Envelope:

M24C02-DRDW3TP/K and M24C02-DRDW8TP/K from STMicroelectronics maintain the 1 MHz clock frequency and comparable access time (450 ns vs. 400 ns) of the original part. Both are AEC-Q100 qualified automotive-grade components with ROHS3 compliance and active product status. M24C02-DRDW3TP/K supports the full -40°C to 125°C temperature range matching the 24LC024H-E/ST, while M24C02-DRDW8TP/K operates to 105°C. Both feature reduced write cycle time (4ms vs. 5ms) and extended voltage supply range (1.8V minimum).

Substitutes with Reduced Clock Frequency:

CAV24C02YE-GT3 (onsemi), M34E02-FDW6TP (STMicroelectronics), BR24G02FVT-3GE2 and BR34E02FVT-3E2 (Rohm Semiconductor), and R1EX24002ATAS0I#U0 (Renesas) operate at 400 kHz clock frequency. These parts are suitable for applications where reduced I2C bus speed is acceptable. CAV24C02YE-GT3 maintains the full -40°C to 125°C operating range and 2.5V to 5.5V supply voltage matching the original specification. M34E02-FDW6TP is verified as DiGi-Electronics programmable. All 400 kHz variants feature 900 ns access time and are ROHS3 compliant with active product status.

Automotive-Grade Options:

CAV24C02YE-GT3 and both M24C02 variants (M24C02-DRDW3TP/K and M24C02-DRDW8TP/K) carry AEC-Q100 qualification, suitable for automotive applications requiring enhanced reliability screening.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 kHz substitute in place of the 1 MHz 24LC024H-E/ST?

A: Yes, provided your application does not require the higher I2C bus speed. The 400 kHz variants (CAV24C02YE-GT3, M34E02-FDW6TP, BR24G02FVT-3GE2, BR34E02FVT-3E2, R1EX24002ATAS0I#U0) maintain identical memory capacity, organization, and interface protocol. Verify that your system timing requirements accommodate the reduced clock frequency and longer access times (900 ns vs. 400 ns).

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

A: Both package variants are physically compatible 8-pin thin shrink small outline packages with 0.173" width and 4.40mm body dimensions, suitable for surface mount assembly. The "-B" designation indicates a variant from Rohm Semiconductor. Pin configuration and footprint compatibility should be verified against your PCB design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts carry ROHS3 compliance certification, matching the environmental compliance status of the 24LC024H-E/ST.

Q: Which substitute offers the widest voltage supply range?

A: M24C02-DRDW3TP/K and M24C02-DRDW8TP/K from STMicroelectronics support 1.8V to 5.5V, providing the lowest minimum supply voltage among all substitutes. BR24G02FVT-3GE2 supports 1.6V minimum. The original 24LC024H-E/ST requires 2.5V minimum.

Q: Can I use a substitute with a narrower operating temperature range?

A: Substitutes with -40°C to 85°C range (BR24G02FVT-3GE2, BR34E02FVT-3E2, M34E02-FDW6TP, R1EX24002ATAS0I#U0) are suitable only if your application does not require operation above 85°C. The original part and CAV24C02YE-GT3, M24C02-DRDW3TP/K support the extended -40°C to 125°C range.

Q: Which substitute has the fastest access time?

A: M24C02-DRDW3TP/K and M24C02-DRDW8TP/K offer 450 ns access time, closest to the original 400 ns specification. All other substitutes feature 900 ns access time.

Q: Are automotive-qualified parts available?

A: Yes, CAV24C02YE-GT3 (onsemi) and M24C02-DRDW3TP/K and M24C02-DRDW8TP/K (STMicroelectronics) are AEC-Q100 qualified for automotive applications.
