24FC04-E/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24FC04-E/ST is a 4Kbit I2C EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 1 MHz with a 450 ns access time and supports a wide supply voltage range of 1.7V to 5.5V. The component is housed in an 8-TSSOP surface mount package and maintains active product status with full RoHS3 compliance. Substitute parts are identified when electrical specifications, memory organization, interface protocol, and physical packaging remain identical across manufacturers or product variants.

Substitute Part Grouping Explanation

The 24FC04H-E/ST qualifies as a parametric equivalent to the 24FC04-E/ST based on strict alignment of all critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Memory Specifications: Both parts maintain identical 4Kbit capacity with 256 x 8 x 2 organization, I2C interface protocol, and 1 MHz clock frequency.

Timing Characteristics: Access time of 450 ns and write cycle time of 5 ms are identical across both parts.

Electrical Performance: Supply voltage range of 1.7V to 5.5V and operating temperature range of -40°C to 125°C are matched.

Physical Package: Both components use 8-TSSOP surface mount packaging with identical dimensions (0.173", 4.40mm Width).

Compliance & Certifications: RoHS3 compliance, MSL rating of 1, and REACH unaffected status are consistent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC04-E/ST and 24FC04H-E/ST maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts should be based on availability and inventory levels. The 24FC04-E/ST currently maintains 1143 pieces in stock, while the 24FC04H-E/ST has 818 pieces available. Both parts carry MSL rating 1 with unlimited moisture sensitivity protection, suitable for standard PCB assembly processes. No additional qualification or testing is required for direct substitution due to complete parametric alignment.

Frequently Asked Questions (FAQ)

Q: Can the 24FC04H-E/ST replace the 24FC04-E/ST in existing designs?

A: Yes. Both parts are parametric equivalents with identical memory capacity, I2C interface, timing specifications, supply voltage range, operating temperature range, and 8-TSSOP package dimensions. Direct substitution is supported without design modification.

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

A: No. Both the 24FC04-E/ST and 24FC04H-E/ST use the 8-TSSOP package with identical dimensions of 0.173" width and 4.40mm overall width. PCB layouts and assembly processes remain unchanged.

Q: What is the significance of the "H" designation in the 24FC04H-E/ST part number?

A: The "H" variant designation indicates a product line variant within Microchip Technology's 24FC04 series. Both variants maintain identical electrical and mechanical specifications, making them functionally interchangeable.

Q: Do both parts require the same handling and storage conditions?

A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard ESD precautions and normal storage conditions apply to both components.

Q: Is there any compliance difference between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.
