IHB1EB220K Equivalent & Substitute Parts

Part Overview

The IHB1EB220K is a 22 µH unshielded wirewound inductor manufactured by Vishay Dale, rated for 5.8 A continuous current with a maximum DC resistance of 20 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in compact form factors. Substitute parts are identified based on matching electrical specifications (inductance value, current rating, DC resistance) and mechanical compatibility (through-hole radial mounting, physical dimensions).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHB1EB220K is determined by the following critical parameters:

• Inductance Value: Must be 22 µH (±10% tolerance acceptable)
• Current Rating: Minimum 5.5 A (acceptable for applications rated up to 5.8 A)
• DC Resistance: Maximum 20 mOhm (ensures equivalent power dissipation characteristics)
• Shielding Type: Unshielded (maintains electromagnetic compatibility profile)
• Mounting Configuration: Through-hole radial, vertical cylinder orientation
• Core Type: Wirewound construction (functional equivalence)

The substitute part 1110-220K-RC from Bourns Inc. meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1110-220K-RC is a direct electrical and mechanical substitute for the IHB1EB220K. Both components share identical inductance values, DC resistance specifications, and through-hole radial mounting configurations. The Bourns part carries ROHS3 compliance certification and operates across the extended temperature range of -55°C to 105°C, providing regulatory alignment for modern applications. The current rating differential (5.5 A vs. 5.8 A) is acceptable for circuits designed within the 5.5 A threshold. Physical dimensions (0.660" diameter, 0.840" maximum height) ensure PCB layout compatibility with the original component footprint.

Frequently Asked Questions (FAQ)

Q: Can the 1110-220K-RC replace the IHB1EB220K in all applications?

A: Yes, provided the circuit current requirement does not exceed 5.5 A. Both components deliver identical 22 µH inductance and 20 mOhm maximum DC resistance. Through-hole radial mounting and physical dimensions are compatible.

Q: What is the significance of the ±10% inductance tolerance on the Bourns part?

A: Inductance tolerance defines the acceptable deviation from the nominal 22 µH value. The ±10% specification on the 1110-220K-RC indicates the part will measure between 19.8 µH and 24.2 µH. This tolerance is standard for wirewound inductors and suitable for general-purpose filtering and energy storage applications.

Q: Does the drum core construction of the Bourns part affect performance compared to the Vishay Dale wirewound design?

A: Both parts are wirewound inductors. The drum core refers to the physical core geometry used in the Bourns design. Electrical performance (inductance, DC resistance, current handling) remains equivalent. Core geometry differences do not impact substitution eligibility when electrical specifications match.

Q: Are there packaging or inventory considerations for this substitution?

A: The IHB1EB220K is available in 720 pieces (new original stock). The 1110-220K-RC is available in 972 pieces (bulk packaging, new original stock). Both represent adequate inventory for production requirements.

Q: What compliance certifications apply to the substitute part?

A: The 1110-220K-RC carries ROHS3 compliance and REACH unaffected status. ECCN classification is EAR99, and HTSUS code is 8504.50.8000. These certifications support regulatory requirements for industrial and commercial applications.
