Engineering Selection Recommendations

The FT24C04A-EMR-B is discontinued at DiGi Electronics. Both FT24C04A-KMR-T and FT24C04A-UMR-B are active products with current availability and are direct functional equivalents.

FT24C04A-KMR-T is recommended as the primary substitute, maintaining identical electrical and mechanical specifications with active product status and confirmed inventory.

FT24C04A-UMR-B is an alternative substitute with identical parametric specifications. This part is supplied in Tube packaging, whereas the main part and primary substitute do not specify packaging format. Both parts maintain ROHS3 compliance and REACH unaffected status.

Selection between the two active substitutes should be based on packaging requirements, supplier availability, and lead time considerations specific to your procurement workflow.

Frequently Asked Questions (FAQ)

Q: Can FT24C04A-KMR-T and FT24C04A-UMR-B be used interchangeably with FT24C04A-EMR-B?

A: Yes. Both parts are parametric equivalents with identical memory capacity, interface protocol, timing specifications, voltage range, temperature range, and package type. They are direct functional substitutes.

Q: What is the difference between FT24C04A-KMR-T and FT24C04A-UMR-B?

A: The primary difference is packaging format. FT24C04A-UMR-B is supplied in Tube packaging. Both parts maintain identical electrical specifications and compliance certifications. Selection depends on your packaging and handling requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. FT24C04A-EMR-B, FT24C04A-KMR-T, and FT24C04A-UMR-B are all ROHS3 compliant and REACH unaffected.

Q: What is the pin configuration compatibility?

A: All three parts use the 8-MSOP package with identical pinout. They are pin-for-pin compatible and require no circuit modifications for substitution.

Q: Can I use these parts in applications requiring extended temperature ranges beyond -40°C to 85°C?

A: No. All three parts are specified for -40°C to 85°C operating temperature. Applications requiring extended temperature ranges require alternative components outside this product family.
