Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-CTV470M is determined by the following critical parameters:

• Inductance Value: Must be 47 µH with ±20% tolerance
• Core Material & Shielding: Ferrite material with shielded construction required
• Mounting Type: Surface mount configuration mandatory
• Package Footprint: 12.00mm × 12.00mm base dimensions required
• Current Handling: Minimum 1.9 A rating; higher ratings acceptable if DC resistance remains within acceptable limits
• DC Resistance: Target range 60–69 mOhm; lower values preferred for reduced power dissipation
• Compliance: ROHS3 compliance required for regulatory alignment

The Würth Elektronik 7447709470 meets all substitution criteria. It maintains identical inductance, core type, shielding, and footprint while offering superior electrical performance through higher current rating (3.8 A) and lower DC resistance (60 mOhm max), with active product status and AEC-Q200 automotive qualification.

Engineering Selection Recommendations

The 7447709470 from Würth Elektronik is the qualified substitute for the obsolete ELL-CTV470M. Selection is based on the following engineering factors:

• Functional Equivalence: Identical inductance value (47 µH) and tolerance (±20%) ensure circuit performance parity
• Electrical Superiority: Higher current rating (3.8 A vs. 1.9 A) and lower DC resistance (60 mOhm max vs. 69 mOhm) provide improved thermal performance and design margin
• Active Product Status: The substitute is in active production, ensuring long-term availability and supply chain stability
• Compliance Alignment: Both components meet ROHS3 requirements; the substitute additionally carries AEC-Q200 automotive qualification, extending application scope
• Physical Compatibility: Identical footprint (12.00mm × 12.00mm) and surface mount configuration enable direct PCB layout reuse
• Height Consideration: The substitute exhibits greater seated height (10.00mm vs. 4.50mm); verify clearance in confined assembly spaces before implementation

Frequently Asked Questions (FAQ)

Q: Can the 7447709470 be used as a direct replacement for the ELL-CTV470M?

A: Yes. Both components share identical inductance (47 µH), tolerance (±20%), core type (ferrite shielded drum core), footprint (12.00mm × 12.00mm), and surface mount configuration. The substitute offers enhanced electrical performance with higher current rating and lower DC resistance.

Q: What is the primary reason for substitution?

A: The ELL-CTV470M is classified as obsolete. The 7447709470 is an active product with equivalent functionality and superior specifications, ensuring design continuity and supply availability.

Q: Are there any physical compatibility concerns?

A: The base footprint is identical (12.00mm × 12.00mm). However, the substitute has a greater seated height (10.00mm vs. 4.50mm). Verify vertical clearance in your PCB assembly before implementation.

Q: Do both parts meet regulatory requirements?

A: Yes. Both components are ROHS3 compliant. The substitute additionally carries AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications.

Q: What are the key electrical differences?

A: The substitute provides higher current rating (3.8 A vs. 1.9 A) and lower maximum DC resistance (60 mOhm vs. 69 mOhm), resulting in reduced power dissipation and improved thermal performance in the same package footprint.

Q: Is the packaging format compatible with existing assembly processes?

A: The ELL-CTV470M packaging format is not specified in available data. The 7447709470 is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly. Confirm compatibility with your procurement and assembly specifications.
