ELL-CTV1R2N Equivalent & Substitute Parts

Part Overview

The ELL-CTV1R2N is a 1.2 µH shielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 6.5 A continuous current with a DC resistance of 4.6mOhm. This component is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, core type, shielding characteristics, and surface mount compatibility while meeting or exceeding the electrical performance requirements of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-CTV1R2N is determined by the following critical parameters:

• Inductance Value: Must be 1.2 µH at 100 kHz test frequency with ±30% tolerance
• Core Material & Type: Ferrite drum core, wirewound construction with shielding
• Current Rating: Must equal or exceed 6.5 A continuous current
• DC Resistance: Must not exceed 4.6mOhm to maintain thermal and efficiency characteristics
• Mounting Configuration: Surface mount, nonstandard package footprint
• Environmental Compliance: ROHS3 compliance and MSL 1 rating required

The NS12575T1R2NN from Taiyo Yuden meets these substitution criteria with equivalent inductance, core type, shielding, and mounting characteristics. The substitute part exceeds the current rating specification (9.15 A vs. 6.5 A) and provides additional performance margin while maintaining compatible physical dimensions and electrical parameters within the defined tolerance band.

Parameter Comparison

Engineering Selection Recommendations

The NS12575T1R2NN qualifies as a functional substitute for the ELL-CTV1R2N based on matching inductance specification, core material, shielding configuration, and surface mount compatibility. Both components maintain ROHS3 compliance and MSL 1 rating, satisfying environmental and regulatory requirements.

The substitute part provides superior current handling capacity (9.15 A vs. 6.5 A), offering increased design margin for applications operating near the original part's current limit. However, the DC resistance of the substitute is higher (6.96 mOhm Max vs. 4.6 mOhm), which may result in increased power dissipation in high-current applications. The physical dimensions differ slightly, with the substitute measuring 12.50mm x 12.50mm versus 12.00mm x 12.00mm, and the seated height is significantly greater (7.85mm vs. 4.50mm). These dimensional differences require verification against PCB layout constraints and available board space before implementation.

Both the original and substitute parts carry limited availability status, indicating that long-term sourcing may require evaluation of additional alternatives or design modification to accommodate more readily available inductors with equivalent electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the NS12575T1R2NN directly replace the ELL-CTV1R2N without circuit modification?

A: The NS12575T1R2NN is electrically compatible as a substitute, maintaining the same 1.2 µH inductance value and core type. However, the increased seated height (7.85mm vs. 4.50mm) and slightly larger footprint (12.50mm x 12.50mm vs. 12.00mm x 12.00mm) require verification of PCB clearance and component placement constraints. The higher DC resistance may affect thermal performance in applications operating at or near the 6.5 A current specification.

Q: What is the significance of the higher DC resistance in the substitute part?

A: The NS12575T1R2NN exhibits a maximum DC resistance of 6.96 mOhm compared to the original 4.6 mOhm. This difference results in increased resistive losses and power dissipation when current flows through the inductor. For applications operating at the full 6.5 A rating, the substitute will generate approximately 51% more heat. Thermal analysis is recommended for high-current applications to ensure the substitute does not exceed temperature limits.

Q: Are both parts suitable for new design implementations?

A: Neither part is recommended for new designs. The ELL-CTV1R2N is classified as Obsolete, and the NS12575T1R2NN carries a "Not For New Designs" status. For new applications, evaluation of currently active inductors with equivalent electrical specifications is necessary to ensure long-term component availability and supply chain stability.

Q: What packaging format is supplied for the NS12575T1R2NN?

A: The NS12575T1R2NN is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The ELL-CTV1R2N packaging format is not specified in the available data.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the ELL-CTV1R2N and NS12575T1R2NN are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000 for export and tariff purposes.
