Parameter Comparison

Engineering Selection Recommendations

Both the 24LC04BH-E/SN and 24LC04B-E/SN are active production components from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical and mechanical parameters are identical. The 24LC04B-E/SN carries verified programmability status through DiGi-Electronics, while the 24LC04BH-E/SN status is not verified. Both components meet the same regulatory and environmental compliance requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 24LC04B-E/SN directly replace the 24LC04BH-E/SN in existing designs?

A: Yes. Both parts share identical memory capacity, I2C interface specifications, timing parameters, supply voltage requirements, operating temperature range, and 8-SOIC package dimensions. Direct substitution is electrically and mechanically compatible.

Q: Are there any differences in the package footprint between these parts?

A: No. Both components use the 8-SOIC package with 0.154" width and 3.90mm dimensions. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 24LC04BH-E/SN and 24LC04B-E/SN are ROHS3 compliant, REACH unaffected, and classified under EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the significance of the "H" designation in the 24LC04BH-E/SN part number?

A: The "H" designation is a Microchip Technology internal code that does not affect electrical performance or functional compatibility. The 24LC04B-E/SN variant without the "H" designation provides identical specifications.

Q: Are there any temperature or voltage operating differences?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and support the same supply voltage range of 2.5V to 5.5V.

Q: Can these parts be used interchangeably in I2C bus applications?

A: Yes. Both parts implement the I2C protocol at 400 kHz with 900 ns access time and 5 ms write cycle time, ensuring full compatibility in I2C bus configurations.
