Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IHB2EB102K are qualified based on the following critical parameters:

• Inductance Value: 1 mH (exact match required)
• Current Rating: Minimum 1 A (IHB2EB102K rated at 1.1 A)
• DC Resistance: 818 mOhm maximum
• Shielding Configuration: Unshielded
• Mounting Technology: Through-hole radial, vertical cylinder package
• Operating Temperature: -55°C to 105°C minimum range
• Inductance Tolerance: ±10% acceptable

The 1120-102K-RC from Bourns Inc. meets all substitution criteria within these electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the IHB2EB102K and 1120-102K-RC are active products suitable for direct substitution in applications requiring 1 mH inductance at 1 A or greater current capacity. The 1120-102K-RC is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements for electronic component procurement. The IHB2EB102K maintains a 1.1 A current rating compared to the 1 A rating of the substitute; applications operating near maximum current should account for this 0.1 A difference. Both components share identical DC resistance specifications and package geometry, ensuring mechanical and electrical compatibility in through-hole circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the 1120-102K-RC replace the IHB2EB102K in all applications?

A: Yes, provided the circuit current does not exceed 1 A. The IHB2EB102K is rated for 1.1 A maximum; the 1120-102K-RC is rated for 1 A maximum. Applications operating below 1 A are fully compatible.

Q: Are the physical dimensions identical between these two parts?

A: Both components use radial, vertical cylinder packaging with identical case dimensions (0.810" diameter, 0.840" maximum seated height). They are mechanically interchangeable in through-hole circuit board designs.

Q: What is the significance of the ±10% inductance tolerance on the 1120-102K-RC?

A: The ±10% tolerance indicates the inductance value may vary between 0.9 mH and 1.1 mH from the nominal 1 mH specification. This is standard for wirewound inductors and acceptable for general-purpose filtering and energy storage applications.

Q: Does the Bourns 1120-102K-RC meet environmental compliance standards?

A: Yes. The 1120-102K-RC is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What is the difference between the core materials?

A: The 1120-102K-RC uses a ferrite drum core, while the IHB2EB102K core material is not specified in the provided data. Both are unshielded wirewound inductors with identical electrical performance at the specified inductance and current ratings.
