Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24VL024/P are classified based on electrical and mechanical parameter compatibility within the I2C EEPROM category. Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

• Memory size: 2Kbit (256 x 8 organization)
• Memory interface: I2C serial protocol
• Package type: 8-DIP through-hole configuration
• Mounting type: Through hole
• Non-volatile EEPROM technology

Secondary Compatibility Parameters:

• Clock frequency: Equal to or greater than 400 kHz
• Access time: Equal to or less than 900 ns
• Supply voltage range: Must encompass or overlap with 1.5V ~ 3.6V
• Write cycle time: 5 ms (standard for this device class)

Parts meeting all primary requirements and maintaining backward compatibility with secondary parameters are classified as direct substitutes. Parts with enhanced specifications (higher clock frequency, extended temperature range, improved access time) remain functionally compatible in applications designed for the 24VL024/P baseline specifications.

Engineering Selection Recommendations

24VL024H/P (Parametric Equivalent)

The 24VL024H/P is a parametric equivalent to the 24VL024/P, offering identical electrical specifications and package configuration. Both devices operate at 400 kHz clock frequency with 900 ns access time, 1.5V ~ 3.6V supply voltage range, and -20°C ~ 85°C operating temperature. The 24VL024H/P maintains full ROHS3 compliance and REACH unaffected status. This part is suitable for direct replacement in applications where the baseline 24VL024/P specifications are required. Selection of this substitute is appropriate when inventory availability of the primary part is limited.

AT24C02D-PUM (MFR Recommended)

The AT24C02D-PUM is a manufacturer-recommended substitute offering enhanced performance specifications while maintaining core functional compatibility. This device operates at 1 MHz clock frequency (2.5x faster than the 24VL024/P) and features a lower access time of 4.5 µs. The AT24C02D-PUM supports an extended operating temperature range of -40°C ~ 85°C compared to the -20°C ~ 85°C of the main part, and maintains supply voltage compatibility within the 1.7V ~ 3.6V range. Both devices share identical 2Kbit memory capacity, 256 x 8 organization, I2C interface, 5 ms write cycle time, 8-DIP package configuration, ROHS3 compliance, and REACH unaffected status. The AT24C02D-PUM is suitable for applications requiring higher clock frequency operation or extended low-temperature performance. Applications designed for the 24VL024/P baseline specifications operate without modification using the AT24C02D-PUM.

Frequently Asked Questions (FAQ)

Q: Can the 24VL024H/P be used as a direct replacement for the 24VL024/P?

A: Yes. The 24VL024H/P is a parametric equivalent with identical electrical and mechanical specifications. Both devices feature 400 kHz clock frequency, 900 ns access time, 1.5V ~ 3.6V supply voltage range, -20°C ~ 85°C operating temperature, and 8-DIP through-hole package. No circuit modifications are required.

Q: What are the advantages of using AT24C02D-PUM over the 24VL024/P?

A: The AT24C02D-PUM provides enhanced clock frequency (1 MHz versus 400 kHz) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 85°C). These specifications enable operation in applications requiring higher data transfer rates or lower temperature environments. The AT24C02D-PUM maintains backward compatibility with 24VL024/P designs.

Q: Are all substitute parts housed in the same package?

A: Yes. The 24VL024/P, 24VL024H/P, and AT24C02D-PUM are all housed in 8-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations. No PCB layout modifications are necessary when substituting between these parts.

Q: Do the substitute parts maintain the same I2C interface protocol?

A: Yes. All listed parts utilize I2C serial communication protocol. The 24VL024H/P operates at 400 kHz I2C frequency, while the AT24C02D-PUM operates at 1 MHz I2C frequency. Both frequencies are backward compatible with 400 kHz I2C bus designs.

Q: What is the memory capacity of each substitute part?

A: All parts, including the main 24VL024/P and substitutes 24VL024H/P and AT24C02D-PUM, provide 2Kbit non-volatile EEPROM memory organized as 256 x 8 bits. Memory capacity and organization are identical across all listed parts.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. The 24VL024H/P and AT24C02D-PUM are both ROHS3 compliant and REACH unaffected, matching the compliance status of the main 24VL024/P part.

Q: What supply voltage ranges are supported by each part?

A: The 24VL024/P and 24VL024H/P support 1.5V ~ 3.6V supply voltage. The AT24C02D-PUM supports 1.7V ~ 3.6V supply voltage. Applications operating at 1.5V ~ 1.7V require the 24VL024/P or 24VL024H/P. Applications operating at 1.7V and above are compatible with all three parts.

Q: Can the AT24C02D-PUM be used in applications designed for 400 kHz I2C operation?

A: Yes. The AT24C02D-PUM operates at 1 MHz I2C frequency but is backward compatible with 400 kHz I2C bus designs. The device automatically adapts to the bus clock frequency. No firmware or software modifications are required.
