ELC-18B101L Equivalent & Substitute Parts

Part Overview

The ELC-18B101L is a 100 µH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 3.2 A continuous current with 57mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates in through-hole radial vertical cylinder configuration with ferrite core construction.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-18B101L is determined by the following critical parameters:

• Inductance Value: Must be 100 µH ±10% tolerance
• Current Rating: Substitute must support minimum 3.2 A continuous current
• DC Resistance: Maximum allowable DCR is 57mOhm to maintain equivalent performance characteristics
• Core Material: Ferrite core construction required
• Mounting Configuration: Through-hole radial vertical cylinder package
• Compliance: ROHS3 compliance mandatory

The RCR1616NP-101K from Sumida America Components Inc. meets the core electrical specifications (100 µH inductance, ferrite core, through-hole mounting) and maintains ROHS3 compliance. However, dimensional and current rating variations exist and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The RCR1616NP-101K qualifies as an electrical equivalent based on matching inductance value, tolerance, ferrite core material, and ROHS3 compliance status. Both parts maintain active or documented product status within their respective manufacturer portfolios, with the substitute offering the advantage of active production availability.

Selection of RCR1616NP-101K requires evaluation of the following deviations from the original specification:

• Current rating reduced from 3.2 A to 2.9 A
• DC resistance increased from 57mOhm to 68mOhm maximum
• Physical dimensions significantly smaller (16mm vs 20mm diameter; 16.5mm vs 27mm height)
• Shielded construction versus unshielded original

These differences must be assessed against specific circuit requirements, thermal management capabilities, and PCB layout constraints before implementation.

Frequently Asked Questions (FAQ)

Q: Can RCR1616NP-101K be used as a direct drop-in replacement for ELC-18B101L?

A: Electrical substitution is possible based on matching inductance and core material. However, the reduced current rating (2.9 A vs 3.2 A), increased DCR (68mOhm vs 57mOhm), and significantly smaller physical dimensions require circuit-level evaluation. PCB layout modifications may be necessary due to dimensional differences.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating capacity, DC resistance specification, physical size, and shielding configuration. The RCR1616NP-101K is smaller and shielded, while the ELC-18B101L is larger and unshielded. Both maintain 100 µH inductance and ferrite core construction.

Q: Are both parts RoHS compliant?

A: Yes, both ELC-18B101L and RCR1616NP-101K are ROHS3 compliant.

Q: What is the inductance tolerance for both parts?

A: Both parts maintain ±10% inductance tolerance at their respective test frequencies.

Q: Does the shielded design of RCR1616NP-101K affect compatibility?

A: Shielding affects electromagnetic coupling characteristics. Applications requiring unshielded construction may experience different performance with the shielded substitute. Circuit-specific analysis is required.

Q: What packaging formats are available for these parts?

A: ELC-18B101L is supplied in standard through-hole format. RCR1616NP-101K is available in Tape & Reel (TR) packaging for automated assembly processes.
