24FC04H-E/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24FC04H-E/P 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-PDIP through-hole package and maintains active product status with ROHS3 compliance. Substitute parts are identified when electrical parameters, memory specifications, interface protocols, and physical packaging remain identical across the product line.

Key Parameters

Substitute Part Grouping Explanation

The 24FC04-E/P qualifies as a parametric equivalent to the 24FC04H-E/P based on strict alignment of the following critical parameters:

• Memory capacity: 4Kbit with identical 256 x 8 x 2 organization
• Interface protocol: I2C at 1 MHz clock frequency
• Electrical performance: 450 ns access time and 5 ms write cycle time
• Supply voltage compatibility: 1.7V ~ 5.5V operating range
• Temperature specification: -40°C ~ 125°C
• Physical packaging: 8-PDIP through-hole configuration
• Compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99 classification

Both parts share the same base product number (24FC04) and maintain active product status. Substitution is valid when circuit design requirements match these specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC04H-E/P and 24FC04-E/P maintain active product status and identical compliance certifications. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation. The 24FC04-E/P currently maintains higher inventory levels (1356 Pcs) compared to the 24FC04H-E/P (769 Pcs), making it a viable alternative when supply constraints exist. Both parts satisfy ROHS3 compliance requirements and REACH regulatory obligations, ensuring compatibility with current manufacturing and environmental standards.
