Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT88SC0204CA-PU is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Package compatibility: 8-DIP (0.300", 7.62mm) form factor
• Mounting type: Through Hole
• Manufacturer: Microchip Technology
• RoHS3 compliance
• REACH unaffected status

The AT88SC0204CA-PU is a secure memory device. The substitute parts identified are EEPROM memory ICs from Microchip Technology's standard memory portfolio. These parts share identical physical packaging and electrical interface characteristics (8-DIP through-hole configuration) and maintain equivalent compliance certifications. All substitute parts operate with I2C interface protocol and provide 2Kbit memory capacity with 256 x 8 organization.

Substitute parts are grouped by electrical performance tier:

• Standard Performance (400 kHz I2C): 24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 24AA025-I/P, 24AA02H-I/P, 24AA52-I/P, 24LC024-I/P, 24LC025-E/P
• Enhanced Performance (1 MHz I2C): 24LC024H-E/P, 24LC024H-I/P

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AT88SC0204CA-PU is obsolete. All identified substitute parts maintain Active product status with Microchip Technology, ensuring long-term availability and continued manufacturing support.

Compliance Alignment: All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part. This ensures regulatory continuity in applications subject to environmental and hazardous substance restrictions.

Packaging and Mounting Compatibility: All substitute parts utilize identical 8-DIP (0.300", 7.62mm) through-hole packaging. This enables direct physical replacement without PCB redesign or mechanical rework.

Selection by Application Requirements:

For applications requiring standard I2C clock frequency (400 kHz) operation: Select from 24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 24AA025-I/P, 24AA02H-I/P, 24AA52-I/P, 24LC024-I/P, or 24LC025-E/P.

For applications requiring enhanced I2C clock frequency (1 MHz) operation: Select 24LC024H-E/P or 24LC024H-I/P.

Supply Availability: 24LC024-I/P offers the highest inventory level (2950 Pcs), followed by 24AA024-I/P (1916 Pcs) and 24AA024H-I/P (1784 Pcs), providing optimal supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the AT88SC0204CA-PU be directly replaced with any of the listed substitute parts?

A: Physical replacement is possible due to identical 8-DIP through-hole packaging. However, functional compatibility depends on application-specific requirements. The original part is a secure memory device, while substitutes are standard EEPROM memory ICs. Applications requiring cryptographic or security-specific functionality may require architectural redesign.

Q: What is the primary difference between 400 kHz and 1 MHz I2C variants?

A: The clock frequency determines the maximum data transfer rate. 400 kHz variants (24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 24AA025-I/P, 24AA02H-I/P, 24AA52-I/P, 24LC024-I/P, 24LC025-E/P) provide standard I2C performance with 900 ns access time. 1 MHz variants (24LC024H-E/P, 24LC024H-I/P) provide enhanced performance with 400 ns access time. Selection depends on system timing requirements.

Q: Are there voltage supply differences among substitute parts?

A: Yes. Most parts operate at 1.7V to 5.5V or 2.5V to 5.5V supply range. 24AA52-I/P operates at 1.8V to 5.5V. Verify supply voltage compatibility with your system design before selection.

Q: What is the significance of the temperature rating variants?

A: Standard variants operate -40°C to 85°C. Extended temperature variants (24LC024H-E/P, 24LC025-E/P) operate -40°C to 125°C. Select extended temperature variants for applications requiring operation in elevated temperature environments.

Q: Which substitute part offers the best inventory availability?

A: 24LC024-I/P provides the highest inventory level at 2950 Pcs, ensuring immediate availability and supply chain reliability for production requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original AT88SC0204CA-PU.
