Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC02BH-I/P are classified based on strict parameter equivalence in the following categories:

Manufacturer Recommended Substitutes maintain identical or superior electrical specifications while preserving I2C interface compatibility, 2Kbit capacity, 256 x 8 organization, and 8-PDIP packaging. These parts are selected when the main part becomes unavailable.

Parametric Equivalents share all critical functional parameters including memory capacity, interface protocol, and package form factor, ensuring direct functional replacement in circuit applications.

Key Parameters Determining Substitution:

• Memory Size: 2Kbit (fixed requirement)
• Memory Organization: 256 x 8 (fixed requirement)
• Memory Interface: I2C (fixed requirement)
• Package / Case: 8-DIP (0.300", 7.62mm) (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Clock Frequency: 400 kHz minimum
• Access Time: 900 ns maximum
• Voltage Supply Range: Must encompass 2.5V ~ 5.5V or broader
• Operating Temperature: Must support -40°C ~ 85°C minimum

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical and Mechanical Specifications):

The 24LC02B-I/P and 24LC024-I/P are direct parametric equivalents to the 24LC02BH-I/P, maintaining identical voltage supply range (2.5V ~ 5.5V), clock frequency (400 kHz), access time (900 ns), and operating temperature range (-40°C ~ 85°C). Both are Active status products with ROHS3 compliance. The 24LC02B-I/P offers the highest inventory availability at 5310 units.

Extended Voltage Range Substitutes:

The 24AA02-I/P, 24AA024-I/P, 24AA024H-I/P, 34AA02-I/P, and AT24HC02C-PUM provide extended lower voltage supply capability (1.7V minimum) compared to the main part (2.5V minimum), enabling operation in lower-power applications while maintaining all other critical parameters. These parts are suitable for designs requiring enhanced voltage flexibility.

Higher Performance Alternatives:

The 34LC02-I/P and AT24HC02C-PUM operate at 1 MHz clock frequency with reduced access times (400 ns and 550 ns respectively), providing faster I2C communication capability. These parts are applicable when higher data transfer rates are required within the same 2Kbit capacity and 8-DIP package constraints.

Extended Temperature Range Option:

The 24LC02B-E/P supports operating temperature range of -40°C ~ 125°C, extending the upper temperature limit by 40°C compared to the main part. This variant is suitable for industrial and automotive applications requiring enhanced thermal performance.

Write Cycle Time Consideration:

The 24LCS22A-I/P specifies a 10ms write cycle time compared to 5ms for the main part. This extended write cycle time does not affect functional compatibility but may impact applications with strict timing requirements for sequential write operations.

All substitute parts maintain ROHS3 compliance and Active product status, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can 24AA02-I/P replace 24LC02BH-I/P in existing designs?

A: Yes. The 24AA02-I/P is a direct functional equivalent with identical memory capacity (2Kbit), interface protocol (I2C 400 kHz), access time (900 ns), and 8-DIP package. The extended voltage supply range (1.7V ~ 5.5V) provides additional design flexibility without affecting compatibility.

Q: What is the difference between 24LC02B-I/P and 24LC02BH-I/P?

A: Both parts share identical electrical specifications and 8-DIP packaging. The primary difference is in base product designation. The 24LC02B-I/P is a parametric equivalent suitable for direct substitution with higher inventory availability (5310 units vs. 1007 units).

Q: When should I use 34LC02-I/P instead of 24LC02BH-I/P?

A: The 34LC02-I/P operates at 1 MHz clock frequency with 400 ns access time, compared to 400 kHz and 900 ns for the main part. Select 34LC02-I/P when faster I2C communication is required. Both maintain 2Kbit capacity and 8-DIP packaging.

Q: Is 24LCS22A-I/P compatible with 24LC02BH-I/P?

A: Yes, with timing consideration. The 24LCS22A-I/P is functionally compatible with identical memory capacity, interface, and package. The 10ms write cycle time (vs. 5ms) may affect applications requiring rapid sequential writes but does not impact pin compatibility or electrical interface.

Q: Can I use AT24HC02C-PUM as a drop-in replacement?

A: Yes. The AT24HC02C-PUM maintains 2Kbit capacity, I2C interface, and 8-DIP package compatibility. It provides enhanced performance with 1 MHz operation and 550 ns access time. The extended voltage range (1.7V ~ 5.5V) offers additional design margin.

Q: What is the inventory status for substitute parts?

A: All substitute parts listed are Active status with current inventory: 24AA02-I/P (1260 Pcs), 24AA024-I/P (1916 Pcs), 24AA024H-I/P (1784 Pcs), 24LC02B-E/P (1503 Pcs), 24LC02B-I/P (5310 Pcs), 24LC024-I/P (2950 Pcs), 24LCS22A-I/P (2900 Pcs), 34AA02-I/P (2923 Pcs), 34LC02-I/P (1083 Pcs), and AT24HC02C-PUM (6136 Pcs).
