ELC-16B682L Equivalent & Substitute Parts

Part Overview

The ELC-16B682L is a 6.8 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 320 mA with a DC resistance of 4.2 Ohm. This component features a radial, vertical cylinder (open) package for through-hole mounting. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-16B682L is determined by the following critical parameters:

• Inductance Value: 6.8 mH (±10% tolerance)
• Mounting Type: Through Hole
• Package Configuration: Radial, Vertical Cylinder
• Shielding: Unshielded
• Compliance: ROHS3 Compliant, MSL 1

The AIUR-06-682K from Abracon LLC meets the core inductance and mounting requirements. However, substitution requires evaluation of current rating and DC resistance differences, as these parameters directly affect circuit performance and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-06-682K is a functionally equivalent substitute for the ELC-16B682L based on matching inductance value, tolerance, through-hole mounting, and unshielded configuration. Both components are ROHS3 compliant with MSL 1 rating.

Key considerations for substitution:

• Current Rating Reduction: The AIUR-06-682K is rated for 220 mA versus the original 320 mA. Circuit designs operating at or near 320 mA require verification that the 220 mA rating is acceptable for the application.
• DC Resistance Increase: The AIUR-06-682K exhibits 8.4 Ohm maximum DCR compared to 4.2 Ohm in the original part. This doubles the resistive loss, affecting power dissipation and thermal performance.
• Physical Dimensions: The substitute part is smaller (0.500" diameter, 0.710" height) compared to the original (0.630" diameter, 0.906" height). PCB layout compatibility must be confirmed.
• Active Product Status: The AIUR-06-682K is an active product with established supply chain availability, addressing the obsolescence of the ELC-16B682L.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-06-682K directly replace the ELC-16B682L in all applications?

A: Direct replacement is possible only if the circuit operates at or below 220 mA and the increased DC resistance of 8.4 Ohm (versus 4.2 Ohm) does not negatively impact circuit performance or thermal requirements. PCB layout must accommodate the smaller physical dimensions.

Q: What is the impact of the doubled DC resistance?

A: Increased DC resistance results in higher power dissipation (P = I²R). For a 200 mA circuit, the original part dissipates 0.168 W while the substitute dissipates 0.336 W. Thermal management and component placement must be re-evaluated.

Q: Are both parts through-hole mounted?

A: Yes, both the ELC-16B682L and AIUR-06-682K use through-hole mounting with radial, vertical cylinder packages. However, the substitute part is physically smaller and may require PCB layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes, both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring equivalent environmental and regulatory compliance.

Q: What is the saturation current of the ELC-16B682L?

A: The saturation current specification is not provided for the ELC-16B682L. The AIUR-06-682K specifies 340 mA saturation current for reference.
