ELF-15N015A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-15N015A is a 2-line common mode choke manufactured by Panasonic Electronic Components, rated for 1.5A maximum current with 170mOhm typical DC resistance. This through-hole component is designed for power line filtering applications in electronic equipment. The part is currently obsolete, making identification of functionally equivalent substitutes necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELF-15N015A is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating: Minimum 1.5A (equal or greater)
• Mounting Type: Through hole only
• Package Configuration: Vertical, 4 PC pin
• DC Resistance: Comparable range (170mOhm baseline)

Two substitute parts meet these criteria:

1. B82722J2152N020 (EPCOS - TDK Electronics): Matches 2-line, 1.5A rating, through-hole vertical configuration with 240mOhm DCR
2. SS11VL-17024 (KEMET): Matches 2-line configuration, exceeds current rating at 1.7A, through-hole vertical configuration with 190mOhm DCR

Both substitutes maintain the core electrical and mechanical compatibility required for direct replacement in the ELF-15N015A application space.

Parameter Comparison

Engineering Selection Recommendations

B82722J2152N020 is suitable for applications requiring exact current rating matching (1.5A) and is backed by active product status with ROHS3 compliance and multiple approval agencies (ENEC, UR, VDE). This part carries higher DC resistance (240mOhm vs. 170mOhm), which may impact thermal performance in current-limited designs.

SS11VL-17024 provides superior current headroom at 1.7A rating and maintains lower DC resistance (190mOhm), closer to the original specification. This part is also active and ROHS3 compliant. The reduced physical height (0.768" vs. 0.886") may affect board layout compatibility in space-constrained applications.

Both substitutes are active products with modern compliance certifications, eliminating the obsolescence constraint of the original ELF-15N015A.

Frequently Asked Questions (FAQ)

Q: Can B82722J2152N020 replace ELF-15N015A in all applications?

A: B82722J2152N020 matches the critical electrical parameters (2-line, 1.5A, through-hole vertical configuration). The 70mOhm increase in DC resistance (240mOhm vs. 170mOhm) must be evaluated for thermal and power dissipation impact in the specific circuit.

Q: What is the primary advantage of SS11VL-17024 over B82722J2152N020?

A: SS11VL-17024 provides 0.2A additional current margin (1.7A vs. 1.5A) and maintains DC resistance closer to the original specification (190mOhm vs. 240mOhm), resulting in lower power dissipation and improved thermal performance.

Q: Are there physical footprint differences between these substitutes?

A: Yes. SS11VL-17024 is shorter (0.768" height vs. 0.886" for ELF-15N015A), while B82722J2152N020 is taller (1.000" height). Length and width dimensions also vary. Board layout verification is required before substitution.

Q: Do both substitutes meet modern compliance requirements?

A: Both B82722J2152N020 and SS11VL-17024 are ROHS3 compliant and active products. B82722J2152N020 carries additional approvals (ENEC, UR, VDE). The original ELF-15N015A is RoHS non-compliant.

Q: Which substitute is recommended for new designs?

A: Selection depends on application constraints. For thermal optimization and current margin, SS11VL-17024 is preferred. For exact current rating matching with additional certifications, B82722J2152N020 is appropriate. Both are active, supported products suitable for production use.
