34VL02/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 34VL02/P is a 2Kbit I2C EEPROM memory IC manufactured by Microchip Technology, housed in an 8-DIP package. This non-volatile memory device operates at 400 kHz clock frequency with 900 ns access time and supports supply voltages from 1.5V to 3.6V. The part is Active status and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits operation within expanded electrical parameters.

Substitute Part Grouping Explanation

Substitute parts for the 34VL02/P are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (24VL024H/P): Maintains identical electrical specifications including 400 kHz clock frequency, 900 ns access time, 1.5V–3.6V supply voltage range, and -20°C to 85°C operating temperature. Package, memory size, organization, and interface remain unchanged. This part provides direct functional replacement with no design modifications required.

MFR Recommended Substitute (AT24C02D-PUM): Operates at higher clock frequency (1 MHz) with faster access time (4.5 µs) and extended operating temperature range (-40°C to 85°C). Supply voltage range is 1.7V–3.6V. Memory size, organization, interface, and package remain identical. This part is suitable for applications where higher performance and wider temperature operation are acceptable or beneficial.

Engineering Selection Recommendations

24VL024H/P Selection: Use this part when direct parametric equivalence is required. Electrical performance, temperature range, and supply voltage specifications are identical to the 34VL02/P. All design parameters remain unchanged. This part is suitable for applications with no tolerance for performance variation.

AT24C02D-PUM Selection: Use this part when extended operating temperature range (-40°C to 85°C) is required or when higher clock frequency (1 MHz) operation is acceptable. The minimum supply voltage increases to 1.7V; verify that system supply voltage meets this requirement. All parts maintain ROHS3 compliance and REACH unaffected status.

Both substitute parts are Active status products from Microchip Technology with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 24VL024H/P be used as a direct replacement for 34VL02/P? A: Yes. The 24VL024H/P maintains identical electrical specifications, operating temperature range, supply voltage range, clock frequency, access time, and package configuration. No design modifications are required.

Q: What is the primary difference between AT24C02D-PUM and the main part? A: The AT24C02D-PUM operates at 1 MHz clock frequency with 4.5 µs access time, compared to 400 kHz and 900 ns for the 34VL02/P. Operating temperature range extends to -40°C. Minimum supply voltage is 1.7V instead of 1.5V.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) package with identical through-hole mounting configuration. PCB layout modifications are not required.

Q: Which substitute part should be selected for low-temperature applications below -20°C? A: The AT24C02D-PUM supports operating temperatures down to -40°C and is suitable for applications requiring operation below -20°C.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the 34VL02/P.

Q: What is the impact of higher clock frequency in AT24C02D-PUM on system design? A: The 1 MHz clock frequency in AT24C02D-PUM is backward compatible with 400 kHz I2C bus operation. Systems designed for 400 kHz operation will function correctly with AT24C02D-PUM at reduced performance. No design changes are required.
