ELL-CTV180M Equivalent & Substitute Parts

Part Overview

The ELL-CTV180M is a 18 µH shielded drum core, wirewound inductor manufactured by Panasonic Electronic Components. Designed for surface mount applications, this component delivers 3 A current rating with 30mOhm DC resistance in a compact 12.00mm x 12.00mm footprint. The part is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-CTV180M is determined by the following critical parameters:

• Inductance Value: 18 µH (fixed requirement)
• Inductance Tolerance: ±20% (acceptable range)
• Core Type: Ferrite, shielded drum core (electromagnetic performance requirement)
• Mounting Type: Surface mount (PCB integration requirement)
• Current Rating: Minimum 3 A (functional requirement)
• DC Resistance: Maximum 35mOhm (thermal and efficiency constraint)
• Package Dimensions: Compatibility with 12.00mm x 12.00mm footprint area
• Compliance: ROHS3 compliant, MSL 1

The SRR1280-180M from Bourns Inc. meets all substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SRR1280-180M is the qualified substitute for the ELL-CTV180M based on the following engineering criteria:

Electrical Compatibility: Both components deliver 18 µH inductance with ±20% tolerance at 100 kHz test frequency. The SRR1280-180M provides 4.8 A current rating, exceeding the original 3 A requirement, with 35mOhm maximum DC resistance within acceptable operational limits.

Compliance & Certification: Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring equivalent environmental and regulatory performance.

Product Status: The SRR1280-180M is active production status, providing long-term supply continuity and availability advantages over the obsolete ELL-CTV180M.

Physical Integration: The SRR1280-180M footprint (12.50mm x 12.50mm) represents a 0.50mm increase in length and width. The seated height increases from 4.50mm to 8.00mm maximum. PCB layout verification is required to confirm vertical clearance compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SRR1280-180M directly replace the ELL-CTV180M without circuit modification?

A: Yes, from an electrical standpoint. Both components share identical inductance value (18 µH), tolerance (±20%), and core type (ferrite shielded drum core). The SRR1280-180M's higher current rating (4.8 A vs. 3 A) and comparable DC resistance (35mOhm max vs. 30mOhm) provide equivalent or improved performance. Physical layout verification is necessary due to dimensional differences.

Q: What are the dimensional constraints for substitution?

A: The SRR1280-180M increases footprint dimensions by 0.50mm in both length and width (12.50mm vs. 12.00mm). The critical difference is seated height: 8.00mm maximum versus 4.50mm for the original part. Confirm PCB clearance above the component location before implementation.

Q: Are there compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant with MSL 1 moisture sensitivity rating. Regulatory and environmental performance are equivalent.

Q: Why is the SRR1280-180M the only substitute listed?

A: Substitution eligibility is determined by strict parameter matching: 18 µH inductance, ±20% tolerance, ferrite shielded drum core, surface mount configuration, minimum 3 A current rating, and maximum 35mOhm DC resistance. The SRR1280-180M meets all criteria. Other inductors may share some parameters but fail to satisfy the complete substitution matrix.

Q: What is the supply status difference between these parts?

A: The ELL-CTV180M is obsolete with 93,900 pieces in current inventory. The SRR1280-180M is active production with 13,511 pieces available. For new designs and long-term production, the SRR1280-180M ensures sustained component availability.
