ELC-09D682F Equivalent & Substitute Parts

Part Overview

The ELC-09D682F is a 6.8 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 100 mA maximum current with 14.4Ohm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within the specified tolerance and mechanical compatibility with through-hole radial mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D682F is determined by the following critical parameters:

• Inductance Value: Must be 6.8 mH within ±10% tolerance
• Current Rating: Must support minimum 100 mA operation
• DC Resistance: Must not exceed 14.4Ohm to maintain circuit performance
• Mounting Configuration: Must be through-hole radial, vertical cylinder format
• Shielding: Must be unshielded to match electromagnetic characteristics
• Compliance: Must maintain ROHS3 compliance for regulatory alignment

The RL895-682K-RC from Bourns Inc. meets all substitution criteria. This part maintains the required 6.8 mH inductance at ±10% tolerance, supports 110 mA current rating (exceeding the 100 mA requirement), and features 13.2Ohm maximum DC resistance (within specification). The through-hole radial, vertical cylinder package ensures mechanical compatibility, and ROHS3 compliance is maintained.

Parameter Comparison

Engineering Selection Recommendations

The RL895-682K-RC is the qualified substitute for the ELC-09D682F based on the following engineering criteria:

Electrical Equivalence: Both inductors maintain 6.8 mH inductance at ±10% tolerance. The RL895-682K-RC current rating of 110 mA exceeds the original 100 mA specification, providing operational margin. The DC resistance of 13.2Ohm maximum is lower than the original 14.4Ohm, resulting in reduced power dissipation and improved circuit efficiency.

Regulatory Compliance: Both components are ROHS3 compliant, ensuring compatibility with current environmental and regulatory requirements.

Product Status: The RL895-682K-RC maintains active production status with confirmed inventory availability (744 Pcs), whereas the ELC-09D682F is obsolete. Selection of the active substitute ensures long-term procurement viability and supply chain continuity.

Mechanical Compatibility: Through-hole radial, vertical cylinder packaging ensures direct board-level compatibility without redesign of mounting footprints or PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the RL895-682K-RC be used as a direct replacement for the ELC-09D682F?

A: Yes. Both inductors share identical inductance values (6.8 mH), tolerance specifications (±10%), and through-hole radial mounting configurations. The RL895-682K-RC exceeds the current rating requirement and maintains lower DC resistance, making it electrically and mechanically compatible.

Q: What is the difference in DC resistance between these parts?

A: The ELC-09D682F has 14.4Ohm DC resistance, while the RL895-682K-RC has a maximum of 13.2Ohm. Lower DC resistance in the substitute reduces I²R losses and heat generation in the circuit.

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant. The RL895-682K-RC additionally carries REACH Unaffected status, providing broader regulatory coverage for international applications.

Q: What is the significance of the "Open" designation in the RL895-682K-RC package description?

A: The "Open" designation refers to the radial, vertical cylinder package configuration and does not affect electrical performance or mechanical compatibility. Both parts use the same through-hole mounting approach.

Q: Why is the ELC-09D682F classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The RL895-682K-RC, maintained in active production by Bourns Inc., provides continuity for designs requiring 6.8 mH unshielded wirewound inductors in this form factor.

Q: Are there dimensional differences between these inductors?

A: Yes. The ELC-09D682F has a diameter of 0.374" (9.50mm) and height of 0.350" (8.90mm). The RL895-682K-RC has a diameter of 0.307" (7.80mm) and height of 0.374" (9.50mm). Both fit standard through-hole radial footprints, though physical dimensions differ slightly.
