IHD3EB222L Equivalent & Substitute Parts

Part Overview

The IHD3EB222L is a 2.2 mH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 500 mA continuous current with a maximum DC resistance of 1.76Ohm. This through-hole axial component operates across the temperature range of -55°C to 125°C and is ROHS3 compliant. The part is currently active in production with 755 units in stock. Substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative packaging or performance characteristics are required.

Substitute Part Grouping Explanation

The 5900-222-RC from Bourns Inc. qualifies as a direct substitute based on the following matching parameters:

• Inductance value: 2.2 mH (identical)
• Current rating: 500 mA (identical)
• Core type: Ferrite drum core, unshielded (identical)
• Mounting configuration: Through-hole axial (identical)
• Inductance test frequency: 1 kHz (identical)
• RoHS compliance: ROHS3 compliant (identical)
• Package format: Axial through-hole (identical)

Substitution is valid where the following parameter variations are acceptable to the application:

• DC resistance tolerance: 1.7Ohm (5900-222-RC) versus 1.76Ohm (IHD3EB222L)
• Inductance tolerance: ±10% (5900-222-RC) versus ±15% (IHD3EB222L)
• Saturation current: 560mA (5900-222-RC) versus 380mA (IHD3EB222L)
• Operating temperature upper limit: 105°C (5900-222-RC) versus 125°C (IHD3EB222L)
• Physical dimensions: Minor variations within axial package class

Parameter Comparison

Engineering Selection Recommendations

Both the IHD3EB222L and 5900-222-RC are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The 5900-222-RC offers improved saturation current performance (560mA versus 380mA) and tighter inductance tolerance (±10% versus ±15%), which may provide operational margin in current-limited applications. The IHD3EB222L supports a higher maximum operating temperature (125°C versus 105°C), which is relevant for thermal-constrained environments. Selection between these parts should be based on the specific thermal and saturation requirements of the target application, with consideration given to the operating temperature ceiling and current headroom needed during circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the 5900-222-RC replace the IHD3EB222L in all applications?

A: The 5900-222-RC is electrically compatible for applications where the operating temperature does not exceed 105°C and where the improved saturation current (560mA) and tighter inductance tolerance (±10%) are acceptable. Applications requiring operation above 105°C must use the IHD3EB222L.

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

A: The DC resistance difference (1.76Ohm versus 1.7Ohm) represents a 3.4% variation. This affects power dissipation and thermal performance. At 500 mA, the IHD3EB222L dissipates 0.44W while the 5900-222-RC dissipates 0.425W. Applications with tight thermal budgets should account for this difference.

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

A: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for high-reliability applications. Compliance certifications are identical between the two parts.

Q: What packaging differences exist between these inductors?

A: The IHD3EB222L is supplied in bulk packaging, while the 5900-222-RC is supplied in tray packaging. Physical dimensions are comparable within the axial through-hole package class, with minor variations (0.460" versus 0.453" diameter).

Q: How do the saturation current ratings affect circuit design?

A: The saturation current (Isat) represents the current level at which inductance begins to degrade. The 5900-222-RC has a higher saturation rating (560mA versus 380mA), providing greater current headroom before inductance degradation occurs. This is relevant for applications operating near the 500 mA continuous rating.
