ELL-CTV471M Equivalent & Substitute Parts

Part Overview

The ELL-CTV471M is a 470 µH shielded drum core, wirewound inductor manufactured by Panasonic Electronic Components. Designed for surface mount applications, this component operates at 580 mA with a DC resistance of 690mOhm and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-CTV471M are qualified based on the following criteria:

• Inductance Value: Exact match at 470 µH with ±20% tolerance
• Core Type: Ferrite drum core construction
• Shielding: Shielded configuration required
• Mounting: Surface mount technology
• Current Handling: Rated current must meet or exceed 580 mA
• DC Resistance: Maximum DCR acceptable within circuit design constraints
• Physical Footprint: Compatible with 12.00mm x 12.00mm base dimensions
• Compliance: ROHS3 compliance maintained

Two substitute parts meet these criteria: Würth Elektronik 744770247 and Sumida America Components Inc. CDRR107NP-471MC.

Parameter Comparison

Engineering Selection Recommendations

744770247 (Würth Elektronik WE-PD Series)

This substitute provides superior current handling at 900 mA, exceeding the original 580 mA specification. The part is active in production with AEC-Q200 automotive qualification and ROHS3 compliance. Operating temperature range of -40°C to 125°C is specified. The increased height of 8.00mm requires PCB layout verification against the original 4.50mm profile. DC resistance of 980mOhm is higher than the original 690mOhm and must be evaluated for circuit performance impact.

CDRR107NP-471MC (Sumida America Components Inc. CDRR107 Series)

This substitute maintains current rating at 680 mA, closely aligned with the original 580 mA specification. The part is active in production with AEC-Q200 automotive qualification and ROHS3 compliance. Operating temperature range of -40°C to 125°C is specified. DC resistance of 680mOhm is nearly equivalent to the original 690mOhm. Physical dimensions of 11.00mm x 11.00mm with 10.00mm height represent a slight footprint reduction in base area but increased height, requiring PCB layout assessment.

Frequently Asked Questions (FAQ)

Q: Can the 744770247 substitute for the ELL-CTV471M in all applications?

A: The 744770247 matches the core inductance, tolerance, shielding, and mounting specifications. However, the increased height (8.00mm vs. 4.50mm) and higher DC resistance (980mOhm vs. 690mOhm) require circuit board layout verification and electrical performance analysis before implementation.

Q: What is the primary difference between the two substitute parts?

A: The 744770247 offers higher current capacity (900 mA) with increased height and DCR, while the CDRR107NP-471MC provides closer DCR matching (680mOhm) with moderate current increase (680 mA) but greater height (10.00mm). Selection depends on circuit current requirements and available PCB vertical clearance.

Q: Are both substitutes RoHS compliant?

A: Both substitute parts are ROHS3 compliant, matching the original ELL-CTV471M specification.

Q: Does the 11.00mm x 11.00mm footprint of the CDRR107NP-471MC affect compatibility?

A: The base footprint reduction from 12.00mm to 11.00mm is a minor dimensional change. However, the increased height of 10.00mm compared to the original 4.50mm requires verification of available vertical clearance on the PCB.

Q: What certifications do the substitute parts carry?

A: Both the 744770247 and CDRR107NP-471MC carry AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications.
