IHA205EB Equivalent & Substitute Parts

Part Overview

The IHA205EB is a 500 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 2.3 A continuous current with a maximum DC resistance of 320 mOhm. This through-hole axial component is designed for general-purpose filtering, energy storage, and signal conditioning applications in electronic circuits.

Substitute parts are identified when they maintain equivalent electrical performance within the specified parameter tolerances and mechanical compatibility for through-hole axial mounting. The primary substitute listed is the Bourns Inc. 5256-RC, which provides comparable inductance and current handling characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHA205EB is determined by the following critical parameters:

• Inductance Value: 500 µH (±20% tolerance acceptable)
• Current Rating: Minimum 2.3 A continuous
• DC Resistance: Maximum 320 mOhm
• Core Configuration: Unshielded drum core wirewound
• Mounting: Through-hole axial package
• Operating Temperature Range: Compatible with -55°C to 105°C

The Bourns 5256-RC meets the inductance and core type requirements. However, its current rating of 2 A is below the IHA205EB specification of 2.3 A, and its DC resistance of 260 mOhm is lower. These differences must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 5256-RC from Bourns Inc. is an active product with ROHS3 compliance and documented operating temperature specifications. Selection between the IHA205EB and 5256-RC depends on circuit current requirements:

• If circuit design requires the full 2.3 A rating, the IHA205EB is the appropriate choice.
• If circuit operation remains below 2 A, the 5256-RC is electrically compatible with identical inductance and lower DC resistance.
• The 5256-RC's lower DCR (260 mOhm vs. 320 mOhm) results in reduced power dissipation and heat generation.
• Both components share identical core type, shielding configuration, and through-hole axial mounting, ensuring mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 5256-RC replace the IHA205EB in all applications?

A: Mechanical and electrical compatibility exists for inductance and core type. However, the 5256-RC current rating of 2 A is lower than the IHA205EB specification of 2.3 A. Substitution is valid only when circuit current requirements do not exceed 2 A.

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

A: The IHA205EB specifies 320 mOhm maximum DCR, while the 5256-RC specifies 260 mOhm maximum. Lower DCR reduces resistive losses and heat generation. Both values are acceptable for general filtering and energy storage applications unless circuit design specifically requires the higher resistance characteristic.

Q: Are these components physically interchangeable?

A: Both components use through-hole axial packaging with unshielded drum core wirewound construction. Physical mounting compatibility is confirmed. Verify PCB footprint spacing accommodates the 0.560" diameter specification of the 5256-RC.

Q: What compliance certifications apply to these parts?

A: The 5256-RC carries ROHS3 compliance and is REACH unaffected. Compliance documentation for the IHA205EB was not provided in the specification data.
