IHA103EB Equivalent & Substitute Parts

Part Overview

The IHA103EB is a 250 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 1.8 A with a maximum DC resistance of 280 mOhm. This through-hole axial component is designed for applications requiring fixed inductance in the 250 µH range with moderate current handling capability. Substitute parts are identified based on matching core specifications, inductance value, and mechanical form factor to ensure direct functional replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IHA103EB are qualified based on the following critical parameters:

• Inductance Value: 250 µH (exact match required)
• Core Configuration: Unshielded drum core wirewound construction
• Mounting Type: Through hole axial package
• Current Rating: Equal to or greater than 1.8 A
• DC Resistance: Electrical performance within acceptable operating range
• Operating Temperature Range: Compatibility with application environment

The Bourns 5254-RC meets these substitution criteria with matching inductance, core type, and mounting configuration, while providing improved current handling (2.5 A) and lower DC resistance (170 mOhm Max).

Parameter Comparison

Engineering Selection Recommendations

The 5254-RC from Bourns Inc. qualifies as a direct substitute for the IHA103EB based on matching inductance value, core configuration, and through-hole axial package. The 5254-RC provides enhanced electrical performance with higher current rating (2.5 A vs. 1.8 A) and lower DC resistance (170 mOhm Max vs. 280 mOhm Max), resulting in reduced power dissipation in the same form factor. The 5254-RC carries ROHS3 compliance certification, meeting regulatory requirements for restricted substances. Both components feature unshielded drum core wirewound construction suitable for general-purpose inductance applications.

Frequently Asked Questions (FAQ)

Q: Can the 5254-RC replace the IHA103EB in existing designs?

A: Yes. Both components share identical inductance (250 µH), core type (unshielded drum core wirewound), and mechanical form factor (through-hole axial). The 5254-RC provides superior electrical characteristics with higher current capacity and lower DC resistance.

Q: What are the key compatibility factors for substitution?

A: Inductance value, core configuration, mounting type, and package form factor must match. Current rating and DC resistance of the substitute must meet or exceed the original component specifications to ensure equivalent or improved performance.

Q: Are there dimensional differences between these components?

A: The 5254-RC has specified dimensions of 0.440" Dia x 1.250" L (11.18mm x 31.75mm). Verify physical fit in your application layout before implementation.

Q: What compliance certifications apply to the substitute?

A: The 5254-RC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: How does lower DC resistance affect circuit performance?

A: Lower DC resistance (170 mOhm vs. 280 mOhm) reduces resistive losses and heat generation during operation, improving efficiency in current-carrying applications.
