IHB4EB100K Equivalent & Substitute Parts

Part Overview

The IHB4EB100K is a 10 µH unshielded wirewound inductor manufactured by Vishay Dale, rated for 21.4 A continuous current with a maximum DC resistance of 5 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in power conversion, filtering, and energy storage circuits. With 1037 pieces in current stock, alternative components may be required due to supply constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IHB4EB100K is determined by the following critical parameters:

• Inductance Value: Must be 10 µH (±10% tolerance acceptable)
• Current Rating: Minimum 21.4 A continuous current capability
• DC Resistance: Maximum 5 mOhm to maintain equivalent power loss characteristics
• Shielding Configuration: Unshielded construction
• Mounting Technology: Through-hole radial configuration
• Core Type: Wirewound construction with ferrite or equivalent core material

The Bourns 1140-100K-RC meets all substitution criteria with equivalent electrical performance and compatible physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the IHB4EB100K and 1140-100K-RC are active products suitable for direct substitution in applications requiring 10 µH inductance at 21+ A current levels. The Bourns 1140-100K-RC provides documented RoHS3 compliance and REACH unaffected status, making it suitable for regulated markets and applications with environmental compliance requirements. The slightly higher saturation current rating (65.3 A vs. unspecified) of the Bourns component provides additional margin in transient current scenarios. Physical form factor differences (vertical cylinder vs. drum core) must be verified against PCB layout constraints and mechanical clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1140-100K-RC directly replace the IHB4EB100K in existing designs?

A: Yes, provided that the physical dimensions (1.500" diameter, 1.030" height) fit within the available PCB space and that the radial lead configuration is compatible with the existing footprint.

Q: Are there differences in electrical performance between these two inductors?

A: Both components meet the core electrical specifications: 10 µH inductance, 21+ A current rating, and 5 mOhm maximum DC resistance. The Bourns component specifies a saturation current of 65.3 A, providing additional performance margin.

Q: What compliance certifications apply to each part?

A: The Bourns 1140-100K-RC is RoHS3 compliant and REACH unaffected. Compliance status for the Vishay Dale IHB4EB100K should be verified with the manufacturer.

Q: Are there packaging or quantity considerations for substitution?

A: The IHB4EB100K is available in standard through-hole packaging with 1037 pieces in stock. The 1140-100K-RC is supplied in bulk packaging with 870 pieces available. Verify minimum order quantities and lead times with your supplier.

Q: What is the operating temperature range for these components?

A: The Bourns 1140-100K-RC operates from -55°C to 105°C. Operating temperature specifications for the Vishay Dale component should be confirmed with the manufacturer's datasheet.
