AT24C04C-SSPD-T Equivalent & Substitute Parts

Part Overview

The AT24C04C-SSPD-T is a 4Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface operation at 400 kHz with 900 ns access time. This component is classified as Active product status and meets automotive-grade requirements with AEC-Q100 qualification. The device operates across a wide supply voltage range of 2.5V to 5.5V and temperature range of -40°C to 125°C, making it suitable for industrial and automotive applications requiring non-volatile memory storage.

Substitute parts are identified when equivalent electrical parameters and mechanical compatibility are maintained, ensuring direct replacement capability without circuit redesign or performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C04C-SSPD-T is determined by strict equivalence across the following critical parameters:

• Memory capacity: 4Kbit EEPROM
• Interface protocol: I2C at 400 kHz maximum frequency
• Electrical performance: 900 ns access time, 5ms write cycle time
• Supply voltage compatibility: 2.5V to 5.5V operating range
• Temperature rating: -40°C to 125°C minimum
• Package format: 8-SOIC surface mount configuration
• Compliance standards: ROHS3 and automotive-grade qualification

All identified substitute parts maintain these parameters without deviation. Differences in memory organization (512 x 8 versus 256 x 8 x 2) do not affect functional substitution when total capacity and interface remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full compliance with ROHS3 environmental standards. The AT24C04C-SSPD-T and CAV24C04WE-GT3 both carry automotive-grade designation with AEC-Q100 qualification, meeting the highest reliability requirements for automotive applications.

The 24LC04BT-E/SN, while functionally equivalent in electrical and mechanical parameters, does not specify automotive-grade or AEC-Q100 qualification. This part is suitable for industrial and consumer applications where automotive certification is not required.

Moisture sensitivity differs across the group: the AT24C04C-SSPD-T specifies MSL 3 (168 hours), while both substitute parts specify MSL 1 (unlimited). Lower MSL ratings indicate superior moisture resistance and reduced handling constraints during assembly and storage.

Selection should prioritize application requirements: automotive-qualified designs should specify either AT24C04C-SSPD-T or CAV24C04WE-GT3. Non-automotive applications may utilize 24LC04BT-E/SN based on cost and availability considerations.

Frequently Asked Questions (FAQ)

Q: Can 24LC04BT-E/SN replace AT24C04C-SSPD-T in automotive applications?

A: The 24LC04BT-E/SN is electrically and mechanically equivalent but lacks automotive-grade designation and AEC-Q100 qualification. Use in automotive designs requires engineering justification and customer approval. For automotive-qualified designs, specify CAV24C04WE-GT3 or AT24C04C-SSPD-T.

Q: What is the significance of Moisture Sensitivity Level differences?

A: MSL 3 (168 hours) requires controlled storage and handling to prevent moisture absorption. MSL 1 (unlimited) indicates the component tolerates standard warehouse conditions without moisture-related degradation. Substitute parts with MSL 1 offer simplified supply chain management.

Q: Are all three parts pin-compatible?

A: Yes. All parts use identical 8-SOIC package configuration with 0.154" width and 3.90mm body dimension. Pin assignments and functional compatibility are maintained across all three parts.

Q: Does memory organization difference (512 x 8 versus 256 x 8 x 2) affect substitution?

A: No. Both configurations deliver 4Kbit total capacity with identical I2C interface operation. Memory organization is an internal architecture detail that does not affect functional substitution or circuit compatibility.

Q: Which substitute part offers the best availability?

A: The 24LC04BT-E/SN shows highest inventory (5,000,400 pcs) compared to AT24C04C-SSPD-T (3,815 pcs) and CAV24C04WE-GT3 (1,206 pcs). Availability should be confirmed with current supplier inventory at time of procurement.
