ELC11D2R7F Equivalent & Substitute Parts

Part Overview

The ELC11D2R7F is a 2.7 µH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components. Designed for through-hole mounting applications, this component delivers 5.1 A current rating with 14 mOhm DC resistance and operates at 10 kHz test frequency. The part is RoHS compliant and carries Moisture Sensitivity Level 1 (unlimited).

This part is currently obsolete. Identifying equivalent substitute components ensures design continuity and maintains supply chain reliability for applications requiring this inductance value and current rating specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the ELC11D2R7F must satisfy the following criteria:

• Inductance value of 2.7 µH with ±20% tolerance
• Ferrite drum core construction, unshielded
• Through-hole radial mounting configuration
• Vertical cylinder package geometry
• Current rating equal to or exceeding 5.1 A
• DC resistance within acceptable operating parameters
• 10 kHz inductance test frequency alignment
• RoHS compliance certification

The SBC4-2R7-662 from KEMET meets these substitution requirements while maintaining electrical and mechanical compatibility with the original ELC11D2R7F specification.

Parameter Comparison

Engineering Selection Recommendations

The SBC4-2R7-662 serves as a direct electrical substitute for the obsolete ELC11D2R7F. Both components share identical inductance values, tolerance specifications, and core construction. The KEMET substitute provides superior current handling capability (6.6 A versus 5.1 A) and includes saturation current specification (9.6 A), offering enhanced performance margin in applications approaching maximum current limits.

The SBC4-2R7-662 maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Physical dimensions are slightly reduced, with the substitute measuring 0.354" diameter and 0.472" height compared to the original 0.453" diameter and 0.547" height. These dimensional differences remain within typical through-hole PCB layout tolerances for radial component placement.

DC resistance increases from 14 mOhm to 20 mOhm maximum. This parameter difference must be evaluated against circuit thermal and efficiency requirements. Applications with strict power dissipation constraints should confirm acceptable performance at the higher resistance value.

Frequently Asked Questions (FAQ)

Q: Can the SBC4-2R7-662 replace the ELC11D2R7F in existing designs?

A: Yes. Both components share identical inductance (2.7 µH), tolerance (±20%), core type (ferrite unshielded drum core), and mounting configuration (through-hole radial). The substitute provides higher current rating and active product status, making it suitable for direct substitution in applications operating at or below 5.1 A.

Q: What is the impact of increased DC resistance on circuit performance?

A: The SBC4-2R7-662 specifies 20 mOhm maximum DCR compared to the original 14 mOhm. This 6 mOhm increase results in higher resistive losses. Applications sensitive to power dissipation or thermal performance should calculate expected losses at operating current levels to confirm acceptability.

Q: Are the physical dimension differences significant for PCB layout?

A: The substitute is slightly smaller (0.354" diameter, 0.472" height versus 0.453" diameter, 0.547" height). These reductions are minor and typically accommodate standard through-hole PCB spacing. Verify clearance in confined layout areas before final design release.

Q: What compliance certifications apply to the substitute part?

A: The SBC4-2R7-662 carries ROHS3 compliance and REACH unaffected status. The original ELC11D2R7F is RoHS compliant. Both meet current regulatory requirements for electronic component use in regulated markets.

Q: Is the higher saturation current specification of the SBC4-2R7-662 relevant for this application?

A: The substitute specifies 9.6 A saturation current, providing additional performance margin above the 5.1 A rated current of the original part. This specification is relevant only in applications where current may approach or exceed rated limits, offering design headroom for transient or peak current conditions.
