24LC08BHT-E/SN EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC08BHT-E/SN is an 8Kbit EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates via I2C interface at 400 kHz clock frequency and is housed in an 8-SOIC surface mount package. The part is currently active in production with 1182 pieces available in inventory.

Substitute parts are identified when they maintain identical or equivalent electrical specifications, mechanical compatibility, and operational parameters. Alternative components may be required due to inventory availability, packaging format preferences, or specific qualification requirements for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC08BHT-E/SN are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Memory capacity: 8Kbit
• Interface protocol: I2C
• Clock frequency: 400 kHz
• Access time: 900 ns
• Write cycle time: 5 ms
• Supply voltage range: 2.5V to 5.5V
• Operating temperature range: -40°C to 125°C

Mechanical Compatibility Criteria:

• Package type: 8-SOIC
• Package dimensions: 0.154" width (3.90mm)
• Mounting type: Surface Mount

Compliance Criteria:

Engineering Selection Recommendations

24LC08BT-E/SN (Microchip Technology)

This substitute maintains complete electrical and mechanical equivalence to the 24LC08BHT-E/SN. The primary distinction is packaging format: Cut Tape (CT) and Digi-Reel® versus Tape & Reel (TR). Both formats are suitable for automated assembly processes. Inventory availability for this part is significantly higher at 24,249 pieces. Product status is active with verified DiGi-Electronics programmability.

CAV24C08WE-GT3 (onsemi)

This substitute provides complete electrical and mechanical equivalence with an additional qualification: AEC-Q100 automotive grade certification. This part is manufactured by onsemi and carries automotive-level reliability qualification. Packaging format is Tape & Reel (TR), matching the main part. Inventory availability is 17,200 pieces. Product status is active. This part is suitable for applications requiring automotive-grade components.

All three parts maintain identical core specifications: 8Kbit EEPROM capacity, I2C interface, 400 kHz operation, 900 ns access time, 5 ms write cycle time, 2.5V to 5.5V supply range, -40°C to 125°C operating temperature, and 8-SOIC surface mount packaging. All parts are ROHS3 compliant with MSL 1 rating and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 24LC08BT-E/SN be used as a direct replacement for the 24LC08BHT-E/SN?

A: Yes. Both parts are manufactured by Microchip Technology and share identical electrical specifications, memory capacity, interface protocol, timing parameters, voltage range, temperature range, and 8-SOIC package dimensions. The only difference is packaging format (Cut Tape versus Tape & Reel), which does not affect functional compatibility.

Q: What is the significance of the CAV24C08WE-GT3 being AEC-Q100 qualified?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. This certification is relevant for applications requiring automotive-grade components. The part maintains identical electrical and mechanical specifications to the main part and other substitutes.

Q: Are all three parts compatible with the same PCB layout and footprint?

A: Yes. All three parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). They are all surface mount components and require the same PCB footprint and solder pad configuration.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® packaging provides components on tape segments or alternative reel formats. Both formats are compatible with standard pick-and-place assembly equipment. Selection depends on production volume and equipment compatibility.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any temperature or voltage operating differences between the parts?

A: No. All three parts operate identically across the -40°C to 125°C temperature range and 2.5V to 5.5V supply voltage range.

Q: Which part should be selected for highest inventory availability?

A: The 24LC08BT-E/SN offers the highest inventory with 24,249 pieces in stock, compared to 17,200 pieces for the CAV24C08WE-GT3 and 1,182 pieces for the main part 24LC08BHT-E/SN.
