Substitute Part Grouping Explanation

The 1120-101K-RC from Bourns Inc. qualifies as a direct substitute based on the following critical parameters:

• Inductance Match: Both parts specify 100 µH, meeting the primary functional requirement
• DC Resistance Equivalence: Both maintain 80 mOhm maximum, ensuring comparable power dissipation characteristics
• Core Configuration: Both are unshielded wirewound inductors, providing identical electromagnetic behavior
• Package Compatibility: Both use radial, vertical cylinder through-hole mounting, allowing direct PCB footprint compatibility
• Current Rating Consideration: The substitute part is rated for 4 A, which exceeds the main part's 3.4 A rating, providing operational margin in applications where the main part is specified

Parameter Comparison

Engineering Selection Recommendations

The 1120-101K-RC is electrically and mechanically compatible with the IHB2EB101K for applications requiring 100 µH inductance at 80 mOhm DC resistance. The substitute part's higher current rating (4 A vs. 3.4 A) and documented ROHS3 compliance provide additional design margin and regulatory alignment. Both parts maintain identical inductance and resistance specifications, ensuring equivalent circuit performance. Selection between these parts should be based on availability, lead time, and compliance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 1120-101K-RC replace the IHB2EB101K in existing designs?

A: Yes. Both parts share identical inductance (100 µH), DC resistance (80 mOhm maximum), core configuration (unshielded wirewound), and package type (radial, vertical cylinder through-hole). The substitute part's higher current rating does not create compatibility issues.

Q: What is the difference between the core types listed?

A: The IHB2EB101K uses a standard unshielded wirewound core, while the 1120-101K-RC specifies a drum core wirewound configuration. Both are unshielded and deliver the same inductance and resistance characteristics required for substitution.

Q: Are there any mechanical differences that affect PCB layout?

A: Both parts use radial, vertical cylinder packaging with through-hole mounting. Physical dimensions may vary slightly; verify specific size and height specifications against PCB footprint requirements before final design release.

Q: Does the substitute part meet regulatory requirements?

A: The 1120-101K-RC is ROHS3 compliant and REACH unaffected. Verify that these certifications align with your application's regulatory requirements.

Q: What tolerance should be expected?

A: The substitute part specifies ±10% inductance tolerance. Confirm that this tolerance is acceptable for your circuit design before implementation.
