ELC-12E562L Equivalent & Substitute Parts

Part Overview

The ELC-12E562L is a 5.6 mH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 170 mA continuous current with 6.6 Ohm DC resistance. This component is designed for through-hole mounting in radial, vertical cylinder configuration. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-12E562L is determined by the following critical parameters:

• Inductance Value: 5.6 mH (±10% tolerance acceptable)
• Current Rating: Minimum 170 mA; higher ratings provide design margin
• DC Resistance: Maximum 6.6 Ohm; lower values reduce power dissipation
• Mounting Configuration: Through-hole, radial, vertical cylinder format
• Physical Dimensions: Compatible footprint for PCB layout
• Compliance: ROHS3 certification required

The AIUR-06-562K from Abracon LLC meets these substitution criteria with equivalent inductance, improved current rating (250 mA), comparable DC resistance (6.3 Ohm max), and identical mounting type and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-06-562K is a direct functional substitute for the obsolete ELC-12E562L based on the following criteria:

• Inductance Match: Both components provide 5.6 mH with ±10% tolerance, meeting circuit inductance requirements
• Current Capacity: The AIUR-06-562K 250 mA rating exceeds the ELC-12E562L 170 mA requirement, providing operational margin
• DC Resistance: The AIUR-06-562K maximum 6.3 Ohm resistance is lower than the ELC-12E562L 6.6 Ohm specification, reducing power dissipation
• Compliance: Both components are ROHS3 compliant, meeting regulatory requirements
• Product Availability: The AIUR-06-562K is active production status with confirmed inventory, ensuring supply continuity
• Physical Compatibility: Identical mounting type and package configuration with slightly reduced dimensions, compatible with existing PCB layouts

The primary design consideration is the transition from shielded (ELC-12E562L) to unshielded (AIUR-06-562K) construction. Circuit-level EMI analysis is required to determine if shielding is functionally necessary for the application.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-06-562K directly replace the ELC-12E562L without PCB modification?

A: Yes, for inductance and current rating requirements. The AIUR-06-562K has a smaller footprint (0.500" Dia vs. 0.531" Dia) and lower height (0.710" vs. 0.768"), which is compatible with existing through-hole mounting holes. However, the unshielded design may require EMI assessment.

Q: What is the impact of changing from shielded to unshielded construction?

A: Shielding reduces electromagnetic interference radiation and susceptibility. The unshielded AIUR-06-562K may introduce EMI in sensitive analog circuits or high-frequency applications. Circuit-level testing is necessary to confirm acceptable performance in the specific application environment.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant. The AIUR-06-562K includes REACH Unaffected status. No compliance barriers exist for substitution.

Q: How do the DC resistance values affect circuit performance?

A: The AIUR-06-562K 6.3 Ohm maximum resistance is lower than the ELC-12E562L 6.6 Ohm specification. Lower resistance reduces I²R power dissipation and heat generation, improving efficiency. This is a favorable characteristic for substitution.

Q: Is the current rating difference significant?

A: The AIUR-06-562K 250 mA rating provides 47% additional current capacity compared to the ELC-12E562L 170 mA rating. This margin improves thermal performance and extends component life under continuous operation.

Q: What is the inductance test frequency difference?

A: The ELC-12E562L is tested at 10 kHz, while the AIUR-06-562K is tested at 1 kHz. Both measurements confirm 5.6 mH inductance within ±10% tolerance. Frequency-dependent inductance variation is within normal wirewound inductor specifications.
