ELC-09D150DF Equivalent & Substitute Parts

Part Overview

The ELC-09D150DF is a 15 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 2.1 A with 35mOhm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain the same inductance value, current rating, and through-hole radial mounting configuration to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D150DF is determined by the following critical parameters:

• Inductance Value: Must be 15 µH (±tolerance acceptable)
• Current Rating: Must support minimum 2.1 A
• DC Resistance: Must not exceed the original 35mOhm specification to maintain circuit performance
• Mounting Type: Must be through-hole radial configuration
• Package / Case: Must be radial, vertical cylinder format
• Shielding: Unshielded configuration required
• Compliance: ROHS3 compliance mandatory for regulatory alignment

The RL895-150K-RC from Bourns Inc. qualifies as a substitute based on matching inductance (15 µH), current rating (2.1 A), mounting type (through-hole radial), and package configuration (radial, vertical cylinder). Both components are ROHS3 compliant and unshielded.

Parameter Comparison

Engineering Selection Recommendations

The RL895-150K-RC is a qualified substitute for the obsolete ELC-09D150DF based on electrical parameter alignment and regulatory compliance. Both components meet the 15 µH inductance and 2.1 A current rating requirements. The Bourns component offers tighter tolerance (±10% vs ±20%), which may provide improved circuit stability. The DC resistance of the RL895-150K-RC is 50mOhm maximum, which is 15mOhm higher than the original specification; this difference must be evaluated within the context of the specific circuit application to determine acceptable performance margins.

The RL895-150K-RC is currently in active production status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance for regulatory requirements. Physical dimensions differ slightly; PCB layout verification is necessary to confirm mechanical fit within the existing design envelope.

Frequently Asked Questions (FAQ)

Q: Can the RL895-150K-RC be used as a direct replacement for the ELC-09D150DF?

A: The RL895-150K-RC meets the core electrical requirements: 15 µH inductance, 2.1 A current rating, through-hole radial mounting, and unshielded configuration. Physical dimensions differ slightly (diameter 0.307" vs 0.374", height 0.374" vs 0.350"), requiring PCB layout verification. The higher DC resistance (50mOhm vs 35mOhm) must be evaluated for circuit impact.

Q: What is the significance of the tolerance difference between these parts?

A: The ELC-09D150DF has ±20% tolerance, while the RL895-150K-RC has ±10% tolerance. Tighter tolerance in the substitute may improve circuit performance consistency but does not prevent substitution if the original design accommodates the wider tolerance range.

Q: Are both components RoHS compliant?

A: Yes, both the ELC-09D150DF and RL895-150K-RC are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the impact of the 15mOhm DC resistance difference?

A: The RL895-150K-RC has 50mOhm maximum DC resistance compared to the original 35mOhm. This 43% increase in resistance will result in higher power dissipation and heat generation under the same current conditions. Circuit thermal analysis and current path evaluation are required to determine acceptability.

Q: Do the physical dimension differences affect PCB compatibility?

A: The RL895-150K-RC has a smaller diameter (0.307" vs 0.374") but slightly greater height (0.374" vs 0.350"). PCB footprint and component clearance must be verified to ensure mechanical fit within the existing design layout.
