Substitute Part Grouping Explanation

Substitute parts for the 24LC04BHT-I/MS are classified based on electrical parameter compatibility and packaging equivalence. The primary substitution criteria are: identical memory capacity (4Kbit), matching memory format (EEPROM), compatible I2C interface, and equivalent surface mount 8-MSOP packaging. Parts are grouped into two categories:

Category 1 - Parametric Equivalents: Parts maintaining identical electrical specifications including 400 kHz clock frequency, 900 ns access time, and 2.5V to 5.5V supply voltage range. These parts are direct functional replacements with no performance trade-offs.

Category 2 - Enhanced Performance Substitutes: Parts with upgraded electrical characteristics including higher clock frequency (1 MHz) and improved access time (400 ns), combined with extended supply voltage range (1.6V or 1.7V minimum). These parts provide superior performance while maintaining backward compatibility through I2C interface standardization and identical memory capacity.

Packaging variations between Tape & Reel (TR) and Cut Tape (CT) with Digi-Reel® do not affect electrical compatibility and represent alternative distribution formats only.

Parameter Comparison

Engineering Selection Recommendations

24LC04BT-I/MS is the primary parametric equivalent, offering identical electrical specifications to the 24LC04BHT-I/MS with matching 400 kHz clock frequency, 900 ns access time, and 2.5V to 5.5V supply voltage range. This part differs only in packaging format (Cut Tape with Digi-Reel® versus Tape & Reel) and carries verified DiGi-Electronics Programmable status. Selection of this part maintains full functional compatibility with no design modifications required.

24AA044T-I/MS provides enhanced performance characteristics with 1 MHz clock frequency and 400 ns access time, supporting extended supply voltage operation down to 1.7V. This part is suitable for applications requiring higher I2C bus speeds or lower voltage operation while maintaining identical memory capacity and interface compatibility.

BR24G04FVM-3AGTTR from Rohm Semiconductor offers 1 MHz clock frequency operation with extended supply voltage range (1.6V minimum) and represents a cross-manufacturer alternative. Memory organization differs at 512 x 8 versus 256 x 8 x 2, though total capacity remains 4Kbit. All parts maintain ROHS3 compliance, unlimited MSL rating, and active product status.

Frequently Asked Questions (FAQ)

Q: Can 24AA044T-I/MS replace 24LC04BHT-I/MS in existing designs?

A: Yes. The 24AA044T-I/MS maintains identical memory capacity (4Kbit), memory format (EEPROM), interface (I2C), and package type (8-MSOP). Enhanced specifications including 1 MHz clock frequency and 400 ns access time provide superior performance. The extended supply voltage range (1.7V minimum versus 2.5V) offers additional design flexibility. No circuit modifications are required.

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

A: Tape & Reel (TR) and Cut Tape (CT) with Digi-Reel® represent alternative distribution and handling formats only. Both formats contain identical electronic components with no electrical or functional differences. Selection between formats depends on assembly process requirements and component handling equipment compatibility.

Q: Is BR24G04FVM-3AGTTR from a different manufacturer compatible?

A: Yes. BR24G04FVM-3AGTTR from Rohm Semiconductor maintains I2C interface compatibility, identical 4Kbit memory capacity, and equivalent 8-MSOP surface mount packaging. Memory organization differs (512 x 8 versus 256 x 8 x 2) but total capacity remains identical. All compliance certifications (ROHS3, unlimited MSL) match the primary part.

Q: Which substitute part offers the best performance?

A: Both 24AA044T-I/MS and BR24G04FVM-3AGTTR provide 1 MHz clock frequency operation with improved access characteristics compared to the 400 kHz specification of 24LC04BHT-I/MS. Selection depends on supply voltage requirements and manufacturer preference within your supply chain strategy.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts maintain active product status with ROHS3 compliance and unlimited moisture sensitivity level rating, ensuring long-term availability and consistent quality standards.
