IHB1EB221K Equivalent & Substitute Parts

Part Overview

The IHB1EB221K is a 220 µH unshielded wirewound inductor manufactured by Vishay Dale, rated for 1.7 A with a maximum DC resistance of 240 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in a vertical cylinder configuration. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHB1EB221K is determined by the following critical parameters:

• Inductance Value: 220 µH (exact match required)
• Current Rating: Minimum 1.6 A (substitute must support circuit current demands)
• DC Resistance: 240 mOhm maximum (electrical performance constraint)
• Shielding Type: Unshielded (electromagnetic compatibility requirement)
• Mounting Configuration: Through Hole, Radial, Vertical Cylinder (mechanical fit requirement)

The substitute part 1110-221K-RC meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1110-221K-RC (Bourns Inc.) is qualified as a direct substitute for the IHB1EB221K based on matching inductance, DC resistance, shielding configuration, and mechanical form factor. The substitute part carries Active product status and holds ROHS3 compliance certification, supporting long-term supply chain stability.

The current rating differential (1.6 A vs. 1.7 A) represents a 5.9% reduction. Circuit design must confirm that operating current remains within the 1.6 A maximum of the substitute part to maintain electrical performance and thermal margins.

Both parts are specified for through-hole radial mounting with identical physical configuration (Radial, Vertical Cylinder), ensuring mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 1110-221K-RC replace the IHB1EB221K in all applications?

A: Substitution is valid when circuit operating current does not exceed 1.6 A. The inductance value, DC resistance, and mechanical form factor are identical. If the circuit requires the full 1.7 A rating of the original part, the substitute may not be suitable.

Q: Are there physical dimension differences between these parts?

A: Both parts are specified as Radial, Vertical Cylinder configuration. The 1110-221K-RC is dimensioned at 0.660" diameter (16.76 mm) with a maximum seated height of 0.840" (21.34 mm). Verify PCB layout clearances if exact dimensions of the IHB1EB221K are not available.

Q: What compliance certifications apply to the substitute part?

A: The 1110-221K-RC holds ROHS3 compliance and is REACH Unaffected. ECCN classification is EAR99 with HTSUS code 8504.50.8000.

Q: How do the DC resistance specifications compare?

A: Both parts specify 240 mOhm maximum DC resistance, ensuring equivalent power dissipation and thermal performance in the circuit.

Q: Is the substitute part actively manufactured?

A: Yes, the 1110-221K-RC carries Active product status from Bourns Inc., supporting ongoing availability and supply chain continuity.
