Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full ROHS3 compliance. The M24C04-DRDW3TP/K and NV24C04DTVLT3G substitute parts carry AEC-Q100 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The 24FC04HT-E/ST remains suitable for general industrial and consumer applications. Selection between these parts should be based on supply chain availability, packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel), and any specific automotive qualification requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can M24C04-DRDW3TP/K replace 24FC04HT-E/ST directly on the PCB?

A: Yes. Both parts share identical electrical specifications (4Kbit I2C EEPROM, 1 MHz, 450 ns access time, 1.7V–5.5V supply) and the same 8-TSSOP package footprint. No PCB modifications are required.

Q: What is the difference between the memory organization values (256 x 8 x 2 versus 512 x 8)?

A: Memory organization notation differs between manufacturers but represents the same 4Kbit capacity. Both configurations deliver identical functional performance in I2C EEPROM applications.

Q: Are the substitute parts suitable for automotive applications?

A: M24C04-DRDW3TP/K and NV24C04DTVLT3G carry AEC-Q100 automotive qualification. The 24FC04HT-E/ST does not list automotive qualification. For automotive designs, the qualified substitutes are preferred.

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

A: Both are surface mount tape formats suitable for automated assembly. Tape & Reel is continuous reel packaging; Cut Tape & Digi-Reel is pre-cut tape on a reel. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Do all three parts have the same write cycle time?

A: The 24FC04HT-E/ST specifies 5ms write cycle time, while M24C04-DRDW3TP/K and NV24C04DTVLT3G specify 4ms. Both values are within acceptable margins for I2C EEPROM applications and do not affect functional interchangeability.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
