Equivalent & Substitute Parts for 24FC04HT-I/MUY

Part Overview

24FC04HT-I/MUY by Microchip Technology is a non-volatile EEPROM memory IC in the memory category, featuring a capacity of 4Kbit, an I2C interface, a 1 MHz clock frequency, and an 8-UDFN (2x3) package for surface mount applications. The device features a 450 ns access time and supports operation over a voltage range of 1.7V to 5.5V, with an operating temperature of -40°C to 85°C. With an active part status, it satisfies ROHS and REACH requirements. Alternative models are sought primarily for inventory flexibility, supply assurance, and to maintain continuity in production when specific part numbers are unavailable.

Engineering Selection Recommendations

All listed substitute parts share an active product status and meet the key regulatory requirements, such as ROHS and REACH. Select among them strictly based on product status and required compliance fields. Inventory considerations and packaging (Tape & Reel, Cut Tape) are provided for logistics planning and should be matched according to assembly line requirements and moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

What parameters are used to qualify substitute parts for 24FC04HT-I/MUY?
Substitution is qualified by matching the manufacturer, memory type, memory size, memory organization, interface (I2C), clock frequency, operating temperature, voltage supply range, package/case, mounting type, and product status.

Are all substitute parts compatible in terms of electrical and mechanical interface?
Yes. All listed substitutes meet the identical specification for electrical and mechanical interface, including package, mounting type, and interface standards.

How does packaging affect part selection?
Packaging (Tape & Reel or Cut Tape) is relevant for automated assembly and handling. Ensure the packaging type matches equipment requirements and moisture sensitivity level (MSL).

Is RoHS and REACH compliance maintained in all substitutes?
For those parts where compliance is provided, ROHS3 and REACH statuses match that of the main part. Confirm based on the compliance field in the comparison table.

Is there any difference in performance or reliability among substitutes?
All listed parametric equivalents have identical performance characteristics according to the specified parameters and part status.
