Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC025T-E/SN are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Memory capacity: 2Kbit (256 x 8 organization)
• Interface protocol: I2C
• Clock frequency: 400 kHz (or higher frequency variants that operate at 400 kHz)
• Package type: 8-SOIC with 0.154" (3.90mm) width
• Memory type: Non-volatile EEPROM
• Mounting: Surface mount

Acceptable Variations:

• Supply voltage range may extend beyond 2.5V ~ 5.5V (lower minimum or higher maximum acceptable)
• Operating temperature range may be narrower (e.g., -40°C ~ 85°C) but must include the application's required range
• Access time may be faster (lower values acceptable)
• Write cycle time may be faster (lower values acceptable)
• Moisture sensitivity level may differ
• Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical equivalence

Substitute parts are grouped by manufacturer and classified as either parametric equivalents or manufacturer-recommended alternatives based on specification alignment.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

24LC02BT-E/SN (Microchip Technology) provides identical electrical and thermal specifications to the 24LC025T-E/SN. Both devices support the full -40°C to 125°C operating range and 2.5V to 5.5V supply voltage window. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel), which does not affect circuit performance. This part is verified for DiGi-Electronics programmability and maintains ROHS3 compliance.

Higher Clock Frequency Alternative:

M24C02-DRMN3TP/K (STMicroelectronics) operates at 1 MHz I2C clock frequency with 450 ns access time and 4ms write cycle time, providing faster performance than the 400 kHz specification. This device qualifies as AEC-Q100 automotive grade and supports the full -40°C to 125°C temperature range. The extended supply voltage range (1.8V ~ 5.5V) provides additional design flexibility. This part is suitable for applications requiring higher I2C bus speeds while maintaining backward compatibility with 400 kHz operation.

Automotive-Qualified Alternatives:

CAV24C02WE-GT3 (onsemi) and BR24G02F-3GTE2 (Rohm Semiconductor) both carry AEC-Q100 automotive qualification. CAV24C02WE-GT3 matches the full temperature range (-40°C ~ 125°C) and supply voltage (2.5V ~ 5.5V) of the main part. BR24G02F-3GTE2 operates within -40°C to 85°C and 1.6V to 5.5V ranges, with package width of 4.40mm (0.173") instead of 3.90mm, requiring PCB layout verification for pin-to-pin compatibility.

Standard Industrial Alternatives:

M24C02-FMN6TP and M24C02-RMN6TP (STMicroelectronics) both provide 400 kHz I2C operation with 900 ns access time matching the main part specifications. M24C02-RMN6TP offers the highest inventory availability (705,200 pcs) and supports 1.8V ~ 5.5V supply range with -40°C ~ 85°C operating temperature. M24C02-FMN6TP supports 1.7V ~ 5.5V with -40°C ~ 85°C range. Both are verified for DiGi-Electronics programmability and ROHS3 compliant.

Selection Criteria by Application:

• Full temperature range requirement (-40°C ~ 125°C): Select 24LC02BT-E/SN, M24C02-DRMN3TP/K, or CAV24C02WE-GT3
• Automotive applications: Select CAV24C02WE-GT3, BR24G02F-3GTE2, or M24C02-DRMN3TP/K
• High-speed I2C bus (1 MHz): Select M24C02-DRMN3TP/K
• Maximum inventory availability: Select M24C02-RMN6TP
• Identical specifications with different packaging: Select 24LC02BT-E/SN

Frequently Asked Questions (FAQ)

Q: Can M24C02-DRMN3TP/K replace 24LC025T-E/SN in a 400 kHz I2C application?

A: Yes. M24C02-DRMN3TP/K operates at 1 MHz I2C clock frequency, which is backward compatible with 400 kHz bus operation. The device will function correctly on a 400 kHz I2C bus. The faster access time (450 ns vs. 900 ns) and write cycle time (4ms vs. 5ms) provide performance margin without affecting compatibility.

Q: What is the difference between 24LC025T-E/SN and 24LC02BT-E/SN?

A: Both parts are manufactured by Microchip Technology with identical electrical specifications: 2Kbit I2C EEPROM, 400 kHz clock frequency, 900 ns access time, 5ms write cycle, 2.5V ~ 5.5V supply, and -40°C ~ 125°C operating range. The difference is packaging format: 24LC025T-E/SN is supplied in Tape & Reel, while 24LC02BT-E/SN is supplied in Cut Tape & Digi-Reel. Both are ROHS3 compliant and in active production.

Q: Can BR24G02F-3GTE2 be used as a direct replacement?

A: BR24G02F-3GTE2 is functionally equivalent for 2Kbit I2C EEPROM applications at 400 kHz. However, the package width differs: 4.40mm (0.173") vs. 3.90mm (0.154") for the main part. PCB layout and footprint compatibility must be verified before substitution. The operating temperature range is limited to -40°C ~ 85°C, which may not suit applications requiring full -40°C ~ 125°C operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (24LC02BT-E/SN, BR24G02F-3GTE2, M24C02-DRMN3TP/K, M24C02-FMN6TP, M24C02-RMN6TP, and CAV24C02WE-GT3) are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the main part.

Q: Which substitute part has the highest inventory availability?

A: M24C02-RMN6TP (STMicroelectronics) has the highest inventory with 705,200 pcs in stock. This part provides 400 kHz I2C operation, 900 ns access time, 5ms write cycle, 1.8V ~ 5.5V supply range, and -40°C ~ 85°C operating temperature in 8-SOIC package.

Q: Can substitute parts with lower operating temperature ranges be used in -40°C ~ 125°C applications?

A: No. Parts with operating temperature ranges limited to -40°C ~ 85°C (BR24G02F-3GTE2, M24C02-FMN6TP, M24C02-RMN6TP) cannot be used in applications requiring operation above 85°C. Select parts with -40°C ~ 125°C rating: 24LC02BT-E/SN, M24C02-DRMN3TP/K, or CAV24C02WE-GT3.

Q: What does "DiGi-Electronics Programmable" mean?

A: DiGi-Electronics Programmable indicates that the part has been verified for programming compatibility with DiGi-Electronics programming equipment and services. Parts marked "Not Verified" have not undergone this specific verification but remain functionally equivalent for standard I2C EEPROM applications.
