Functional Equivalence: Both the original part and substitute maintain identical pulse transformer functionality, ensuring circuit performance remains unchanged during component replacement.

Manufacturer Consistency: Both components are manufactured by Würth Elektronik, guaranteeing design compatibility and adherence to the same manufacturing standards and specifications.

Part Family Relationship: The substitute part number 749010017A represents a direct evolution within the same product line, indicated by the alphanumeric suffix designation standard in Würth Elektronik's naming convention.

Supply Chain Status: The transition from obsolete (749010017) to active production status (749010017A) ensures continued availability and long-term procurement viability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The 749010017A is the appropriate selection. This component carries active production status, ensuring availability throughout the design lifecycle and into production phases. The part meets ROHS3 compliance requirements and carries REACH unaffected status, satisfying modern regulatory requirements for electronic components in regulated markets.

For Existing Inventory Management: The original 749010017 remains available with 1006 units in stock. However, transition planning to 749010017A is recommended to align with active product lines and ensure compliance with evolving environmental and regulatory standards.

Compliance Advantage: The 749010017A provides documented RoHS3 compliance and REACH unaffected status, eliminating compliance verification requirements and reducing regulatory risk in supply chain documentation.

Moisture Handling: The MSL rating of 1 (Unlimited) for the 749010017A indicates no moisture sensitivity constraints, simplifying storage, handling, and logistics procedures compared to components with higher MSL ratings.

Frequently Asked Questions (FAQ)

Q: Can the 749010017A directly replace the 749010017 in existing circuit designs?

A: Yes. Both components are pulse transformers manufactured by Würth Elektronik with identical functional classification. The alphanumeric suffix in the part number indicates a direct product line evolution rather than a functional redesign.

Q: What is the significance of the obsolete status for the 749010017?

A: Obsolete status indicates the manufacturer has discontinued active production. While existing inventory remains available, long-term procurement cannot be guaranteed. The 749010017A represents the active replacement within the product family.

Q: Does the 749010017A require different handling procedures than the original part?

A: No. The MSL rating of 1 (Unlimited) for the 749010017A actually simplifies handling by eliminating moisture sensitivity constraints. Standard electronic component storage and handling practices apply.

Q: Are there compliance differences between the two parts?

A: The 749010017A includes documented ROHS3 compliance and REACH unaffected status. The original 749010017 does not specify these certifications. For applications requiring regulatory compliance documentation, the 749010017A is the appropriate choice.

Q: What inventory considerations should guide component selection?

A: The 749010017 has 1006 units available; the 749010017A has 764 units available. For immediate requirements, either part may be sourced. For long-term projects, the 749010017A is recommended due to active production status.
