Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHB3EB220K is determined by the following critical parameters:

• Inductance Value: Must be 22 µH (±10% tolerance acceptable)
• Current Rating: Minimum 10.6 A; higher ratings provide design margin
• DC Resistance: Maximum 11 mOhm to maintain equivalent power loss characteristics
• Shielding Configuration: Unshielded to match electromagnetic interference profile
• Mounting Type: Through hole radial configuration for PCB compatibility
• Operating Temperature Range: Must support the application's thermal environment

The substitute part 1130-220K-RC from Bourns Inc. meets all critical substitution criteria, offering equivalent inductance and DC resistance specifications with an enhanced current rating of 14.6 A.

Parameter Comparison

Engineering Selection Recommendations

The 1130-220K-RC qualifies as a direct substitute for the IHB3EB220K based on matching inductance (22 µH), DC resistance (11 mOhm maximum), and shielding configuration (unshielded). The substitute part offers a higher current rating (14.6 A versus 10.6 A), providing additional thermal and electrical margin in the application.

The 1130-220K-RC carries Active product status and ROHS3 compliance certification, confirming ongoing manufacturer support and regulatory alignment for new designs and production applications. The ferrite drum core construction and specified operating temperature range (-55°C ~ 105°C) support standard industrial and commercial operating environments.

Physical form factor compatibility should be verified during board layout integration, as the IHB3EB220K uses a vertical cylinder package while the 1130-220K-RC employs a radial drum core configuration. Both are through-hole mounted components suitable for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1130-220K-RC replace the IHB3EB220K in existing designs?

A: Yes. Both components share identical inductance (22 µH) and DC resistance (11 mOhm maximum) specifications. The substitute part's higher current rating (14.6 A) ensures compatibility with applications designed for the 10.6 A rated component. Physical footprint and lead spacing must be verified for PCB compatibility.

Q: What is the significance of the higher current rating on the 1130-220K-RC?

A: The 14.6 A rating on the substitute part provides additional design margin compared to the 10.6 A rating of the main part. This allows the component to operate at lower temperature rise and reduced stress in current-limited applications, extending component life and improving reliability.

Q: Are there differences in core material between these parts?

A: The IHB3EB220K core material is not specified in the available data. The 1130-220K-RC uses a ferrite drum core. Both components are unshielded wirewound inductors with matching inductance and resistance characteristics, making them functionally equivalent for circuit performance.

Q: What packaging and mounting considerations apply?

A: Both parts are through-hole mounted radial inductors. The IHB3EB220K uses a vertical cylinder package, while the 1130-220K-RC employs a drum core radial package. Lead pitch, body diameter, and height dimensions should be confirmed against PCB layout requirements before substitution.

Q: Is the 1130-220K-RC suitable for new product designs?

A: Yes. The 1130-220K-RC carries Active product status and ROHS3 compliance, confirming manufacturer support and regulatory compliance for production applications. The specified operating temperature range (-55°C ~ 105°C) supports standard industrial and commercial environments.
