Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24C02CT-E/SN are grouped based on the following critical parameters that determine functional compatibility:

Core Compatibility Requirements:

• Memory capacity: 2Kbit (256 x 8 organization)
• Interface protocol: I2C serial communication
• Package type: 8-SOIC surface mount configuration
• Pin count and pinout: 8-pin SOIC standard

Performance Variation Parameters:

• I2C clock frequency: 100 kHz (main part) to 1 MHz (enhanced substitutes)
• Access time: 4.6 µs to 450 ns
• Write cycle time: 1.5 ms to 4 ms
• Supply voltage range: 4.5V ~ 5.5V (main part) to 1.6V ~ 5.5V (extended range substitutes)
• Operating temperature: -40°C ~ 125°C (main part) to -40°C ~ 85°C (standard substitutes)

Substitutes are classified into three categories: direct equivalents (identical specifications), performance-enhanced variants (higher clock frequency, faster access), and extended-capability versions (wider voltage or temperature ranges, automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): The 24C02C-E/SN from Microchip Technology is a direct functional equivalent with identical electrical and performance characteristics. The only difference is packaging format (Tube versus Tape & Reel). This part is suitable for direct substitution when packaging format is not a constraint.

Performance-Enhanced Substitutes (Higher Clock Frequency): The 24LC02BT-E/SN, M24C02-FMN6TP, M24C02-RMN6P, and M24C02-RMN6TP offer 400 kHz I2C clock frequency compared to the 100 kHz specification of the main part. These parts provide faster data access (900 ns versus 4.6 µs) and are backward compatible in systems designed for the 24C02CT-E/SN. All are active products with ROHS3 compliance.

Extended Voltage Range Substitutes: The BR24G02F-3GTE2 (1.6V ~ 5.5V), CAT24C03WI-GT3 (1.8V ~ 5.5V), M24C02-DRMN3TP/K (1.8V ~ 5.5V), M24C02-FMN6TP (1.7V ~ 5.5V), and M24C02-RMN6P/RMN6TP (1.8V ~ 5.5V) support lower minimum supply voltages than the main part. These are applicable in systems requiring operation below 4.5V.

Automotive-Qualified Substitutes: The CAV24C02WE-GT3 and M24C02-DRMN3TP/K carry automotive qualification (AEC-Q100) and are suitable for automotive applications. The CAV24C02WE-GT3 maintains the full -40°C ~ 125°C temperature range of the main part.

Parts Not Recommended for New Designs: The BR24C02-MN6TP is marked "Not For New Designs" and should be avoided in new product development. The CAT24C03WI-GT3 is obsolete and should not be selected for new applications.

Highest Performance Option: The M24C02-DRMN3TP/K offers the highest I2C clock frequency (1 MHz) with the fastest access time (450 ns), extended voltage range (1.8V ~ 5.5V), full temperature range (-40°C ~ 125°C), and automotive qualification. This part is suitable for applications requiring maximum performance and environmental robustness.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 kHz I2C part as a substitute for the 100 kHz 24C02CT-E/SN? A: Yes. Parts operating at higher I2C clock frequencies (400 kHz, 1 MHz) are backward compatible with systems designed for 100 kHz operation. The I2C protocol allows devices to operate at lower clock speeds than their maximum specification. Verify that your system controller supports the higher frequency if you intend to utilize it.

Q: What is the difference between the 24C02CT-E/SN and 24C02C-E/SN? A: These parts are electrically and functionally identical. The difference is packaging format: 24C02CT-E/SN is supplied in Tape & Reel format, while 24C02C-E/SN is supplied in Tube format. Select based on your assembly process requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part.

Q: Which substitute offers the widest voltage operating range? A: The BR24G02F-3GTE2 supports 1.6V ~ 5.5V, the widest minimum voltage specification among all listed substitutes. The M24C02-DRMN3TP/K, CAT24C03WI-GT3, M24C02-FMN6TP, and M24C02-RMN6P/RMN6TP support 1.8V ~ 5.5V.

Q: Can I use the CAT24C03WI-GT3 in a new design? A: No. The CAT24C03WI-GT3 is marked as obsolete and should not be selected for new product development. Use active alternatives such as the CAV24C02WE-GT3 or M24C02 series from STMicroelectronics.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging? A: Both are tape-based packaging formats suitable for automated assembly. Cut Tape & Digi-Reel is pre-cut for pick-and-place equipment, while standard Tape & Reel is continuous tape. Select based on your assembly equipment compatibility.

Q: Which substitute is recommended for automotive applications? A: The CAV24C02WE-GT3 and M24C02-DRMN3TP/K both carry AEC-Q100 automotive qualification. The CAV24C02WE-GT3 maintains the full -40°C ~ 125°C temperature range, while the M24C02-DRMN3TP/K also offers 1 MHz I2C frequency and extended voltage range.

Q: Is the 24LC02BT-E/SN a suitable substitute? A: Yes. The 24LC02BT-E/SN is a Microchip Technology part with 400 kHz I2C frequency, 900 ns access time, and extended voltage range (2.5V ~ 5.5V). It maintains the full -40°C ~ 125°C operating temperature range and is actively produced.

Q: What is the inventory status of substitute parts? A: Inventory levels vary. The M24C02-RMN6TP has the highest inventory (705,200 pcs), followed by M24C02-FMN6TP (27,113 pcs) and CAV24C02WE-GT3 (19,357 pcs). Verify current availability with your supplier for production requirements.
