ELC11D151F Equivalent & Substitute Parts

Part Overview

The ELC11D151F is a 150 µH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.4 A with a DC resistance of 180 mOhm. This through-hole component features a radial, vertical cylinder package and is RoHS compliant. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC11D151F is determined by the following critical parameters:

• Inductance Value: 150 µH (exact match required)
• Inductance Tolerance: ±10% (must match or be tighter)
• Core Material: Ferrite, unshielded drum core (same electromagnetic characteristics)
• Mounting Type: Through hole radial configuration
• Package / Case: Radial, vertical cylinder format
• Inductance Test Frequency: 10 kHz (measurement standard)

The substitute part SBCP-14HY151B from KEMET meets all primary electrical and mechanical criteria. While the current rating differs slightly (1.3 A vs. 1.4 A) and DC resistance is higher (200 mOhm Max vs. 180 mOhm), these variations remain within acceptable engineering tolerances for equivalent substitution in applications where the ELC11D151F is specified.

Parameter Comparison

Engineering Selection Recommendations

The SBCP-14HY151B is a qualified equivalent for the obsolete ELC11D151F based on the following factors:

• Electrical Equivalence: Both components share identical inductance values (150 µH) and tolerance specifications (±10%), tested at the same frequency (10 kHz).
• Mechanical Compatibility: Both use ferrite drum core construction with unshielded design and through-hole radial mounting. Physical dimensions are comparable, with the KEMET part slightly larger (0.472" vs. 0.453" diameter; 0.591" vs. 0.547" height).
• Compliance Status: The SBCP-14HY151B is ROHS3 compliant and currently in active production, ensuring long-term availability and supply chain stability compared to the obsolete Panasonic part.
• Current and Resistance Trade-offs: The KEMET substitute has a marginally lower current rating (1.3 A vs. 1.4 A) and higher DC resistance (200 mOhm Max vs. 180 mOhm). These differences require evaluation against specific circuit requirements; applications operating near the 1.4 A limit should be reassessed.

Frequently Asked Questions (FAQ)

Q: Can the SBCP-14HY151B directly replace the ELC11D151F without circuit modification?

A: The SBCP-14HY151B is electrically equivalent for inductance and tolerance. However, the higher DC resistance (200 mOhm vs. 180 mOhm) and lower current rating (1.3 A vs. 1.4 A) must be verified against your circuit's operating conditions. If the circuit operates below 1.3 A and the additional 20 mOhm resistance is acceptable, direct substitution is feasible.

Q: Are there physical fit concerns when substituting these parts?

A: The SBCP-14HY151B is slightly larger in both diameter (0.472" vs. 0.453") and height (0.591" vs. 0.547"). PCB layout and mechanical clearance must be confirmed before substitution to ensure the component fits within the allocated space.

Q: What is the difference between "Radial, Vertical Cylinder" and "Radial, Vertical Cylinder (Open)"?

A: Both designations refer to the same radial lead configuration with vertical orientation. The "(Open)" notation in the KEMET part indicates an open-frame construction style, which is functionally equivalent for through-hole mounting applications.

Q: Why is the KEMET part listed as ROHS3 compliant while the Panasonic part is RoHS compliant?

A: ROHS3 represents the current RoHS 2.0 directive compliance standard. Both parts meet RoHS requirements; ROHS3 is the updated designation for active production components.

Q: Is the SBCP-14HY151B available in the same packaging as the ELC11D151F?

A: The ELC11D151F is listed as obsolete with limited stock (652 pcs). The SBCP-14HY151B is in active production with higher availability (976 pcs in stock) and is supplied in bulk packaging, making it suitable for production and replacement applications.
