IHD3ER220L Equivalent & Substitute Parts

Part Overview

The IHD3ER220L is a 22 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 4 A continuous current with a maximum DC resistance of 24 mOhm. This through-hole axial component is designed for applications requiring fixed inductance in power conversion, filtering, and signal conditioning circuits. With 972 pieces in current stock, this part remains available for immediate procurement. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IHD3ER220L are qualified based on the following critical parameters:

• Inductance Value: 22 µH (exact match required)
• Current Rating: Minimum 3.8 A (acceptable tolerance for applications not requiring full 4 A margin)
• DC Resistance: Maximum 30 mOhm (acceptable tolerance within engineering limits)
• Core Configuration: Unshielded drum core wirewound construction
• Mounting Type: Through hole axial package
• Operating Temperature Range: Compatible with -55°C to 105°C specification

The Bourns Inc. 5900-220-RC meets these substitution criteria with equivalent inductance, compatible current handling, and matching mechanical form factor. The slightly higher DCR (30 mOhm vs. 24 mOhm) and lower saturation current (5.7 A vs. implied higher rating) represent acceptable trade-offs for applications where the primary inductance value and general current capacity are the controlling design parameters.

Parameter Comparison

Engineering Selection Recommendations

The 5900-220-RC from Bourns Inc. qualifies as a direct substitute for the IHD3ER220L based on matching inductance value, compatible current handling capability, and identical mechanical form factor. The Bourns part carries active product status and ROHS3 compliance certification, confirming ongoing manufacturing support and regulatory alignment.

Selection between these parts should be based on application-specific current margin requirements. The IHD3ER220L provides a 4 A continuous rating, while the 5900-220-RC is rated at 3.8 A. For applications operating near maximum current limits, the Vishay Dale part offers additional headroom. For applications with current demands below 3.8 A, the Bourns substitute provides equivalent performance with established supply availability (2907 pieces in stock).

The 6 mOhm difference in maximum DCR (24 mOhm vs. 30 mOhm) introduces minimal power dissipation variance in typical circuit applications and should be evaluated only in thermally constrained designs or high-current continuous-duty applications.

Frequently Asked Questions (FAQ)

Q: Can the 5900-220-RC replace the IHD3ER220L in all applications?

A: The 5900-220-RC is electrically and mechanically compatible for applications where the continuous current requirement does not exceed 3.8 A and where the slightly higher DCR (30 mOhm vs. 24 mOhm) does not create thermal or efficiency constraints. Verify application current profiles before substitution.

Q: What is the significance of the DCR difference between these parts?

A: DC resistance directly affects power dissipation in the inductor. At 4 A continuous current, the IHD3ER220L dissipates approximately 384 mW (4² × 0.024), while the 5900-220-RC dissipates approximately 456 mW (3.8² × 0.030). This 72 mW difference is negligible in most applications but should be considered in thermally sensitive designs.

Q: Are both parts suitable for high-frequency applications?

A: Both parts are unshielded drum core wirewound inductors designed for general-purpose filtering and power conversion. The 5900-220-RC specifies inductance measurement at 1 kHz. For applications requiring operation at significantly higher frequencies, verify frequency-dependent performance characteristics with the manufacturer.

Q: What packaging considerations apply to these parts?

A: Both parts use through-hole axial mounting and are mechanically interchangeable on standard PCB layouts. The 5900-220-RC is supplied in tray packaging, while the IHD3ER220L packaging format is not specified. Confirm packaging compatibility with assembly and handling requirements.

Q: Is the Bourns part certified for regulated industries?

A: The 5900-220-RC carries ROHS3 compliance and REACH unaffected status, confirming compliance with current environmental and hazardous substance regulations. The IHD3ER220L certification status is not specified in available data.
