Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-16B220L is determined by the following critical parameters:

• Inductance Value: Must be 22 µH with ±10% tolerance
• Current Rating: Substitute must support minimum 4.6 A; higher ratings are acceptable
• DC Resistance: Lower or equal DCR values are preferred to maintain circuit performance
• Mounting Type: Through-hole configuration required
• Package Configuration: Radial, vertical cylinder form factor
• Shielding: Unshielded specification
• Compliance: ROHS3 compliance required

The substitute part 1110-220K-RC from Bourns Inc. meets all substitution criteria with improved electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1110-220K-RC from Bourns Inc. is a direct substitute for the obsolete ELC-16B220L. Both components are ROHS3 compliant and meet the electrical requirements of 22 µH inductance at ±10% tolerance. The Bourns part offers superior electrical performance with a higher current rating of 5.5 A versus 4.6 A, and lower DC resistance of 20mOhm maximum compared to 31mOhm. The active product status of the 1110-220K-RC ensures long-term availability and supply chain continuity. Physical form factors are compatible for through-hole PCB mounting in radial, vertical cylinder configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1110-220K-RC replace the ELC-16B220L in existing designs?

A: Yes. Both components share identical inductance values (22 µH), tolerance (±10%), shielding (unshielded), mounting type (through-hole), and package configuration (radial, vertical cylinder). The Bourns part has superior electrical characteristics with higher current rating and lower DC resistance.

Q: What is the significance of the lower DC resistance in the Bourns substitute?

A: The 1110-220K-RC has 20mOhm maximum DCR compared to 31mOhm in the Panasonic part. Lower DC resistance reduces power dissipation and heat generation in the inductor, improving circuit efficiency.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The Bourns part additionally provides defined operating temperature range (-55°C ~ 105°C), whereas the Panasonic part does not specify this parameter.

Q: Does the drum core construction of the Bourns part affect compatibility?

A: No. The drum core, wirewound construction of the 1110-220K-RC is compatible with the wirewound specification of the ELC-16B220L. Both maintain unshielded configuration and identical electrical performance at the specified inductance and tolerance values.

Q: What is the inventory status of these parts?

A: The ELC-16B220L (Panasonic) is obsolete with 1083 pieces in stock. The 1110-220K-RC (Bourns) is active with 972 pieces in stock, providing ongoing availability for new production.
