Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2401Z is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must be classified as Silicon Serial Number devices with identical base product number (DS2401).

Package Compatibility: The substitute must maintain the same physical package specification: SOT-223-3 supplier device package with TO-261-4 and TO-261AA case designations. This ensures mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Mounting Technology: Surface Mount mounting type must be preserved to maintain compatibility with automated assembly processes and board design specifications.

Application Alignment: The substitute must support the same application domains: PCB integration, Network Node identification, and Equipment Identification/Registration functions.

Electrical Characteristics: Both parts operate within the same electrical parameter set as defined by the DS2401 base product family.

The DS2401Z+ qualifies as a direct substitute based on these criteria. The primary distinction is product status and compliance certification, not functional or mechanical parameters.

Engineering Selection Recommendations

For New Designs and Production: The DS2401Z+ is the appropriate selection. This part maintains identical functional and mechanical specifications while offering Active product status and ROHS3 compliance certification. Active status ensures long-term availability and supply chain stability. ROHS3 compliance aligns with current environmental and regulatory requirements for electronic component manufacturing and distribution.

For Legacy System Maintenance: The DS2401Z remains functionally equivalent for applications where RoHS compliance is not a contractual or regulatory requirement. However, the Obsolete status indicates limited future availability. Transition planning to DS2401Z+ is recommended for sustained production support.

Compliance Considerations: Organizations subject to RoHS3 regulations or customer specifications requiring RoHS compliance must use DS2401Z+. Both parts maintain identical REACH and ECCN classifications, indicating no change in export control or chemical substance restrictions.

Supply Chain Planning: Current inventory levels show DS2401Z+ availability at 1413 pieces, compared to DS2401Z at 16243 pieces. For immediate requirements, DS2401Z stock is available; for ongoing production, DS2401Z+ ensures continued supply.

Frequently Asked Questions (FAQ)

Q: Can DS2401Z+ be used as a direct replacement for DS2401Z in existing designs?

A: Yes. Both parts share identical package specifications (SOT-223-3), mounting type (Surface Mount), and functional classification (Silicon Serial Number). PCB layouts, footprints, and assembly processes require no modification. The primary differences are product status and RoHS compliance certification.

Q: What is the significance of the "+" designation in DS2401Z+?

A: The "+" suffix indicates a product variant with updated compliance certifications. In this case, DS2401Z+ carries ROHS3 compliance, whereas DS2401Z does not. Functionally and mechanically, both parts are equivalent.

Q: Are there any electrical parameter differences between DS2401Z and DS2401Z+?

A: No electrical parameter differences are specified in the provided technical data. Both parts are based on the same DS2401 base product and operate within identical electrical specifications.

Q: Why is DS2401Z classified as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this specific part number. DS2401Z+ represents the current active equivalent, ensuring ongoing availability and manufacturer support.

Q: What packaging formats are available?

A: DS2401Z+ is supplied in Tube packaging. DS2401Z packaging format is not specified in the available data. Confirm packaging requirements with your procurement specification before ordering.

Q: Are moisture sensitivity considerations different between the two parts?

A: No. Both DS2401Z and DS2401Z+ carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can I mix DS2401Z and DS2401Z+ components in the same production batch?

A: Yes, from a functional and mechanical perspective. However, quality assurance and traceability protocols may require component consistency within a single production lot. Consult your quality management procedures and customer specifications.
