Substitute Part Grouping Explanation

Substitution of the Würth Elektronik 749020016 pulse transformer is based on the following criteria:

Primary Substitution Logic:

• Functional category equivalence: Both components must be classified as pulse transformers
• Manufacturer consistency: Würth Elektronik maintains design and performance standards across product lines
• Product status transition: Active status substitute ensures ongoing availability and manufacturing support
• Compliance alignment: Substitute parts must meet current regulatory requirements (RoHS3, REACH)

Key Parameters Determining Substitution:

• Component type: Pulse transformer
• Electrical function: Signal coupling and pulse transmission
• Manufacturing status: Transition from obsolete to active product line
• Regulatory compliance: RoHS3 and REACH compliance status

Engineering Selection Recommendations

Primary Substitute: Würth Elektronik 7490200101

The 7490200101 serves as the direct active substitute for the obsolete 749020016 pulse transformer. Selection rationale:

• Product Status: The 7490200101 maintains active manufacturing status, ensuring continued availability and supply chain stability
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status satisfy current environmental and safety requirements for new designs and production
• Moisture Sensitivity: MSL 1 rating indicates unlimited shelf life and minimal moisture-related handling constraints
• Manufacturer Continuity: Both components originate from Würth Elektronik, ensuring design philosophy and quality standards alignment
• Inventory Availability: Sufficient stock of 903 units supports immediate procurement requirements

For applications currently utilizing the 749020016, transition to the 7490200101 is supported by functional equivalence within the pulse transformer category and enhanced compliance posture.

Frequently Asked Questions (FAQ)

Q: Why is the 749020016 being phased out?

A: The 749020016 has reached obsolete status in Würth Elektronik's product lifecycle. The 7490200101 represents the active equivalent within the current product portfolio, offering improved compliance certifications and manufacturing continuity.

Q: Are the 749020016 and 7490200101 electrically interchangeable?

A: Both components are classified as pulse transformers from Würth Elektronik and function within the same product category. Electrical interchangeability is determined by circuit-specific requirements including impedance, frequency response, and coupling characteristics, which are not differentiated in the provided specifications.

Q: What is the significance of ROHS3 compliance on the 7490200101?

A: ROHS3 compliance indicates the 7490200101 meets current European Union Restriction of Hazardous Substances directives, restricting specified hazardous materials. This certification is required for components entering new production and markets with environmental compliance mandates.

Q: What does MSL 1 (Unlimited) mean for the 7490200101?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without moisture-related degradation concerns. This eliminates special storage, handling, and baking requirements associated with higher MSL ratings.

Q: Can I continue using existing stock of the 749020016?

A: Existing inventory of the 749020016 remains functional for current applications. However, new designs and long-term production should transition to the 7490200101 to ensure supply continuity and compliance with evolving regulatory requirements.

Q: What does REACH Unaffected status mean?

A: REACH Unaffected status indicates the 7490200101 does not contain substances of very high concern (SVHC) listed under the EU REACH regulation, eliminating compliance documentation and notification requirements for this component.
