PCF8582C-2P/03,112 EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The PCF8582C-2P/03,112 is a 2Kbit I2C EEPROM memory IC manufactured by NXP Semiconductors in 8-DIP through-hole packaging. This component operates at 100 kHz I2C clock frequency with a supply voltage range of 2.5V to 6.0V and temperature range of -40°C to 85°C. The part is classified as obsolete, making equivalent substitute components necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCF8582C-2P/03,112 is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory Size: 2Kbit (256 x 8 organization)
• Memory Interface: I2C protocol
• Package Type: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Memory Format: EEPROM (Non-Volatile)

Operational Compatibility Criteria:

• I2C Clock Frequency: Substitute parts must support 100 kHz minimum operation
• Voltage Supply Range: Substitute parts must overlap with 2.5V ~ 6.0V range
• Operating Temperature: Substitute parts must support -40°C ~ 85°C range or compatible subset
• RoHS Compliance: ROHS3 Compliant status maintained

All substitute parts listed meet these core requirements. Differences in maximum clock frequency (400 kHz vs. 100 kHz), access time specifications, and write cycle times do not prevent substitution, as these represent enhanced or alternative performance characteristics within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components from Microchip Technology, providing continuity for designs currently using the obsolete PCF8582C-2P/03,112. Selection among substitutes depends on specific application requirements:

For applications requiring full temperature range (-40°C ~ 85°C): 24C02C-I/P, 24LC024-I/P, or 24LC02B-I/P are suitable. The 24LC02B-I/P offers verified programmability status and highest inventory availability (5310 units).

For applications with reduced temperature range (0°C ~ 70°C): 24C02C/P, 24LC024/P, or 24LC02B/P are suitable. The 24LC02B/P provides the highest inventory level (15100 units) among this group.

For applications requiring extended voltage range (2.5V ~ 5.5V or wider): 24LC024-I/P, 24LC024/P, 24LC02B-I/P, and 24LC02B/P support 2.5V minimum supply voltage. The 24C02C variants support 4.5V minimum only.

All substitute parts maintain ROHS3 compliance and are electrically compatible with I2C bus operation at 100 kHz and above.

Frequently Asked Questions (FAQ)

Q: Can the 24C02C-I/P directly replace the PCF8582C-2P/03,112 in all applications?

A: The 24C02C-I/P is electrically compatible for I2C EEPROM functionality. However, its supply voltage range (4.5V ~ 5.5V) is narrower than the original part (2.5V ~ 6.0V). Verify your application's supply voltage falls within 4.5V ~ 5.5V before selection.

Q: What is the difference between 24LC02B-I/P and 24LC02B/P?

A: Both parts are functionally identical 2Kbit I2C EEPROM devices. The primary difference is operating temperature range: 24LC02B-I/P supports -40°C ~ 85°C, while 24LC02B/P supports 0°C ~ 70°C. Select based on your application's temperature requirements.

Q: Are all substitute parts pin-compatible with the original PCF8582C-2P/03,112?

A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout for I2C EEPROM operation.

Q: Why do substitute parts operate at 400 kHz I2C frequency when the original operates at 100 kHz?

A: The substitute parts support higher maximum I2C clock frequencies (400 kHz) but are fully backward compatible with 100 kHz operation. Your application will function at 100 kHz with any substitute part listed.

Q: Which substitute part has the best inventory availability?

A: The 24LC02B/P has the highest inventory level at 15100 units in stock. The 24LC02B-I/P provides 5310 units with extended temperature range (-40°C ~ 85°C).

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original PCF8582C-2P/03,112.
