Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC04BHT-E/SN is determined by strict alignment of the following critical parameters:

• Memory capacity: 4Kbit
• Interface protocol: I2C serial communication
• Clock frequency: 400 kHz minimum
• Access time: 900 ns or faster
• Supply voltage range: 2.5V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C
• Package: 8-SOIC form factor
• Mounting: Surface mount technology
• Compliance: ROHS3 compliant

Two substitute parts meet these criteria: the 24LC04BT-E/SN from Microchip Technology and the CAV24C04WE-GT3 from onsemi. Both devices maintain identical electrical specifications and package dimensions, with differences limited to packaging format and organizational details.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance, ensuring regulatory alignment for current and future applications. The 24LC04BT-E/SN from Microchip Technology offers the highest inventory availability at 5,000,400 units and is verified for DiGi-Electronics programmability, making it the preferred substitute when supply chain continuity is prioritized. The CAV24C04WE-GT3 from onsemi includes AEC-Q100 automotive qualification, positioning it as the appropriate selection for automotive-grade applications requiring enhanced reliability documentation. Both substitutes are electrically and mechanically interchangeable with the 24LC04BHT-E/SN within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the 24LC04BT-E/SN replace the 24LC04BHT-E/SN in production designs?

A: Yes. Both devices are manufactured by Microchip Technology and share identical electrical specifications, memory organization, I2C interface, clock frequency, access time, supply voltage range, operating temperature range, and 8-SOIC package dimensions. The only difference is packaging format: the 24LC04BHT-E/SN uses Tape & Reel, while the 24LC04BT-E/SN uses Cut Tape and Digi-Reel. Selection depends on assembly line requirements and tape format compatibility.

Q: Is the CAV24C04WE-GT3 suitable for non-automotive applications?

A: Yes. The CAV24C04WE-GT3 meets all electrical and mechanical requirements for standard industrial and consumer applications. The AEC-Q100 automotive qualification is an additional certification that does not restrict use in other markets. This part is appropriate when automotive-grade reliability documentation is required or when sourcing from onsemi is preferred.

Q: What is the difference in memory organization between the main part and substitutes?

A: The 24LC04BHT-E/SN and 24LC04BT-E/SN both use 256 x 8 x 2 organization. The CAV24C04WE-GT3 uses 512 x 8 organization. Both configurations deliver 4Kbit total capacity and are functionally equivalent for I2C EEPROM applications.

Q: Are all three parts pin-compatible?

A: Yes. All three devices use the 8-SOIC package with identical pin assignments and electrical characteristics, ensuring direct PCB-level compatibility without design modifications.

Q: Which substitute offers the best supply availability?

A: The 24LC04BT-E/SN from Microchip Technology has the highest inventory at 5,000,400 units in stock, providing superior supply chain security for high-volume production.
