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

Part Overview

The 24FC04-I/ST is a 4Kbit I2C EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 1 MHz clock frequency with 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 identical electrical specifications, memory organization, interface protocol, and physical packaging are maintained across alternative part numbers from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

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

• Memory capacity and organization (4Kbit, 256 x 8 x 2)
• Interface protocol (I2C)
• Clock frequency (1 MHz)
• Access time (450 ns)
• Write cycle time (5 ms)
• Supply voltage range (1.7V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (8-TSSOP with identical dimensions)
• Compliance certifications (RoHS3, REACH Unaffected)
• Moisture sensitivity level (MSL 1)

Both parts are manufactured by Microchip Technology and maintain active product status. Substitution is valid when the application requires identical electrical performance, memory capacity, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC04-I/ST and 24FC04H-I/ST maintain active product status and full compliance with RoHS3 and REACH regulations. Selection between these parts is based on availability and inventory levels rather than electrical or mechanical differentiation. The 24FC04H-I/ST currently maintains higher inventory availability (2026 pcs) compared to the 24FC04-I/ST (1245 pcs). Both components are suitable for direct substitution in applications requiring 4Kbit I2C EEPROM functionality with the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including memory capacity, interface protocol, timing characteristics, voltage range, and package dimensions. Direct substitution is valid without design modification.

Q: Are there differences in the part numbers that affect compatibility?

A: The part numbers differ only in the suffix designation (24FC04-I/ST versus 24FC04H-I/ST). Both share the same base product number (24FC04) and maintain identical electrical specifications and physical packaging. The suffix variation does not affect functional compatibility.

Q: What is the significance of the 8-TSSOP package specification?

A: The 8-TSSOP package is a surface mount thin shrink small outline package with 8 pins. The specified dimensions (0.173" width, 4.40mm) ensure mechanical compatibility with PCB footprints designed for this package type. Both substitute parts use identical package specifications.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both the 24FC04-I/ST and 24FC04H-I/ST operate across the identical temperature range of -40°C to 85°C (TA), supporting applications requiring extended temperature performance.

Q: What compliance certifications apply to both parts?

A: Both parts maintain RoHS3 compliance and REACH Unaffected status. Both carry MSL rating 1 (Unlimited moisture sensitivity level), indicating no moisture sensitivity restrictions during storage and handling.
