ELC-16B562L Equivalent & Substitute Parts

Part Overview

The ELC-16B562L is a 5.6 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 340 mA with a DC resistance of 3.7 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 support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-16B562L is determined by the following critical parameters:

• Inductance value must match: 5.6 mH
• Inductance tolerance must be within ±10%
• Current rating must meet or exceed 340 mA
• DC resistance must be compatible with circuit requirements
• Shielding type must be unshielded
• Mounting type must be through-hole
• Package configuration must be radial, vertical cylinder
• RoHS3 compliance required

The AIUR-06-562K from Abracon LLC meets these substitution criteria with matching inductance, tolerance, unshielded configuration, and through-hole mounting. While the current rating is lower at 250 mA, the saturation current (Isat) of 370 mA provides operational headroom for the specified 340 mA application.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-06-562K is a qualified substitute for the ELC-16B562L based on matching inductance specifications, tolerance, unshielded configuration, and through-hole mounting. Both components maintain ROHS3 compliance and MSL Level 1 ratings.

The primary design consideration is the DC resistance differential: the AIUR-06-562K exhibits 6.3 Ohm maximum resistance compared to the original 3.7 Ohm specification. Circuit designs must account for this increased resistive loss. The lower current rating of 250 mA on the AIUR-06-562K requires verification against actual circuit current demands; however, the saturation current specification of 370 mA indicates operational capability at the 340 mA design point.

Physical dimensions differ between the two components. The AIUR-06-562K is smaller in both diameter (0.500" vs. 0.630") and height (0.710" vs. 0.906"), which may require PCB layout verification to ensure mechanical compatibility within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-06-562K directly replace the ELC-16B562L in existing designs?

A: The AIUR-06-562K meets the core electrical specifications (5.6 mH inductance, ±10% tolerance, unshielded, through-hole mounting). However, the increased DC resistance (6.3 Ohm vs. 3.7 Ohm) and reduced current rating (250 mA vs. 340 mA) require circuit analysis. The saturation current of 370 mA provides operational margin at 340 mA, but power dissipation will increase due to higher DCR. PCB layout must accommodate smaller physical dimensions.

Q: What is the impact of the higher DC resistance on circuit performance?

A: The 2.6 Ohm increase in DC resistance will increase power dissipation and voltage drop across the inductor. For a 340 mA current, the voltage drop increases from approximately 1.26 V to 2.14 V. Circuit designs sensitive to voltage drop or thermal management must be re-evaluated.

Q: Are both components RoHS compliant?

A: Yes, both the ELC-16B562L and AIUR-06-562K are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Does the smaller package size of the AIUR-06-562K affect compatibility?

A: The AIUR-06-562K is physically smaller (0.500" diameter, 0.710" height) compared to the ELC-16B562L (0.630" diameter, 0.906" height). PCB footprints and mechanical clearances must be verified to ensure the substitute component fits within the available space.

Q: What is the difference between the core materials?

A: The ELC-16B562L uses a standard wirewound core, while the AIUR-06-562K uses a drum core with ferrite material. Both achieve the same 5.6 mH inductance specification with ±10% tolerance and unshielded configuration.
