Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT24C02C-SSPD-T are qualified based on the following critical parameters:

• Memory Capacity: 2Kbit with 256 x 8 organization
• Interface Protocol: I2C serial communication
• Package Type: 8-SOIC surface mount configuration
• Supply Voltage Compatibility: Overlapping operating voltage ranges
• Write Cycle Time: 5ms specification
• Compliance Standards: RoHS3 compliance and automotive qualification

The BR24L02FJ-WE2 from Rohm Semiconductor meets these substitution criteria with identical memory capacity, I2C interface, and 8-SOIC package footprint. Functional equivalence is established through matching memory organization, write cycle performance, and package mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the AT24C02C-SSPD-T and BR24L02FJ-WE2 are active products with current inventory availability and full RoHS3 compliance. The Microchip device carries AEC-Q100 automotive qualification, establishing its suitability for automotive applications. The Rohm substitute provides extended lower voltage operation (1.8V minimum) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3), making it suitable for applications with relaxed temperature requirements up to 85°C. Clock frequency differences (1 MHz versus 400 kHz) do not affect functional substitution for standard I2C memory applications, as both devices support the I2C protocol specification. Selection between these parts should be based on specific application temperature range requirements and supply voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can the BR24L02FJ-WE2 directly replace the AT24C02C-SSPD-T in existing designs?

A: Yes, for applications operating within the BR24L02FJ-WE2 temperature range (-40°C to 85°C) and supply voltage range (1.8V to 5.5V). Both devices share identical 2Kbit capacity, 256 x 8 organization, I2C interface, and 8-SOIC package footprint. The 400 kHz clock frequency of the substitute is compatible with I2C protocol requirements.

Q: What are the key differences between these two parts?

A: The primary differences are clock frequency (1 MHz versus 400 kHz), maximum operating temperature (125°C versus 85°C), minimum supply voltage (2.5V versus 1.8V), and moisture sensitivity level (MSL 3 versus MSL 1). Memory capacity, interface protocol, package type, and write cycle time are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the AT24C02C-SSPD-T and BR24L02FJ-WE2 are ROHS3 compliant and REACH unaffected.

Q: Which part should I select for automotive applications?

A: The AT24C02C-SSPD-T carries AEC-Q100 automotive qualification. If automotive qualification is a design requirement, this part is the specified choice. The BR24L02FJ-WE2 may be used in non-automotive or less stringent applications.

Q: Does the lower clock frequency of the BR24L02FJ-WE2 affect performance?

A: No. Both 1 MHz and 400 kHz clock frequencies support standard I2C communication. The 400 kHz frequency is within the I2C specification range and does not impact functional performance for typical memory access patterns.

Q: What is the significance of the MSL rating difference?

A: MSL 3 (168 hours) indicates the AT24C02C-SSPD-T requires controlled moisture exposure during storage and handling. MSL 1 (unlimited) for the BR24L02FJ-WE2 indicates no moisture sensitivity restrictions, providing greater flexibility in storage and handling conditions.
