Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC024HT-E/SN is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory Size: 2Kbit (256 x 8 organization)
• Memory Interface: I2C protocol
• Voltage Supply Range: Minimum 2.5V support required
• Operating Temperature: Minimum -40°C to 125°C range required
• Package Type: 8-SOIC or 8-SOP footprint compatibility
• Write Cycle Time: 5 ms maximum

Variable Parameters Allowing Substitution:

• Clock Frequency: 400 kHz or 1 MHz operation acceptable
• Access Time: 400 ns to 900 ns acceptable
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Tube acceptable
• Temperature Range: Extended ranges (-40°C to 85°C or -40°C to 105°C) acceptable if minimum requirements met
• Voltage Range: Extended ranges (1.6V to 5.5V or 1.8V to 5.5V) acceptable if 2.5V minimum maintained

Substitute parts are grouped by manufacturer (Microchip Technology, Rohm Semiconductor, onsemi) and by operational characteristics (clock frequency, temperature range, voltage range).

Frequently Asked Questions (FAQ)

Q: Can I substitute 24LC024HT-E/SN with 24LC024H-E/SN? A: Yes. Both parts are identical in electrical specifications and operate at 1 MHz with 400 ns access time. The only difference is packaging format: 24LC024HT-E/SN uses Tape & Reel while 24LC024H-E/SN uses Tube. Both maintain Active product status and full temperature range (-40°C to 125°C).

Q: What is the impact of using a 400 kHz part instead of 1 MHz? A: The 400 kHz variants (24LC02BT-E/SN, BR24A02F series, BR24L02F series, CAV24C02WE-GT3) operate at half the clock frequency. This results in extended access time (900 ns versus 400 ns). Substitution is valid only if your system design accommodates the slower clock speed and extended access time. I2C protocol compatibility is maintained.

Q: Are 8-SOIC and 8-SOP packages interchangeable? A: No. While both are 8-pin surface mount packages, they have different physical dimensions and pin spacing. 8-SOIC (0.154" width) and 8-SOP (0.173" width) require different PCB footprints. Verify your board design before selecting a substitute with different package type.

Q: Which substitute part has the best availability? A: BR24L02F-WE2 has the highest inventory at 39,785 pcs. This Rohm Semiconductor part operates at 400 kHz with extended low-voltage support (1.8V minimum) and is verified for DiGi-Electronics programmability.

Q: Can I use automotive-grade parts in non-automotive applications? A: Yes. Automotive-grade parts (BR24A02F-WME2, BR24A02FJ-WME2, CAV24C02WE-GT3) with AEC-Q100 qualification exceed standard requirements and are suitable for non-automotive use. They provide additional reliability assurance but may have higher cost.

Q: What is the difference between MSL 1 and MSL 3 ratings? A: MSL 1 (Unlimited) indicates the part has unlimited shelf life without moisture baking. MSL 3 (168 Hours) requires moisture baking within 168 hours of package opening. 24LC02BT-E/SN has MSL 3 rating; most other substitutes have MSL 1 rating.

Q: Which substitute maintains the full -40°C to 125°C temperature range? A: Only 24LC024H-E/SN (Microchip, Tube packaging) and CAV24C02WE-GT3 (onsemi, automotive-grade) maintain the full -40°C to 125°C operating range. All Rohm Semiconductor substitutes are limited to -40°C to 85°C or -40°C to 105°C.

Q: Is the 24LC024HT-E/SN programmable through DiGi-Electronics? A: The 24LC024HT-E/SN programmability status is Not Verified. The 24LC02BT-E/SN, BR24L02F-WE2, and BR24L02FJ-WE2 are Verified for DiGi-Electronics programmability.
