Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHB3EB330K is determined by the following critical parameters:

• Inductance Value: Must be 33 µH (±10% tolerance acceptable)
• Current Rating: Minimum 8.5 A; higher ratings provide design margin
• DC Resistance: Maximum 17 mOhm; lower values reduce power dissipation
• Core Configuration: Unshielded wirewound construction
• Mounting Interface: Through-hole radial package
• Operating Temperature Range: Compatible with application requirements

The Bourns 1130-330K-RC meets all substitution criteria with equivalent inductance and DC resistance specifications, while providing an enhanced current rating of 14.6 A.

Engineering Selection Recommendations

The 1130-330K-RC from Bourns Inc. is a direct functional substitute for the IHB3EB330K. Selection should be based on:

• Current Margin: The 1130-330K-RC provides 58% higher current capacity (14.6 A vs. 8.5 A), offering improved thermal headroom in applications approaching rated current limits.
• Regulatory Compliance: The 1130-330K-RC carries ROHS3 compliance certification, suitable for applications with environmental or procurement requirements.
• Electrical Performance: Identical inductance and DC resistance specifications ensure equivalent circuit behavior.
• Physical Compatibility: Both components utilize through-hole radial mounting; verify PCB footprint spacing before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1130-330K-RC replace the IHB3EB330K in existing designs?

A: Yes. Both components provide 33 µH inductance with 17 mOhm maximum DC resistance and through-hole radial mounting. The higher current rating of the 1130-330K-RC does not create compatibility issues; it provides additional design margin.

Q: What is the primary difference between these two inductors?

A: The 1130-330K-RC features a drum core construction and higher current rating (14.6 A vs. 8.5 A). Both maintain identical inductance and DC resistance specifications.

Q: Are there physical dimension differences that affect PCB layout?

A: The IHB3EB330K uses a vertical cylinder package, while the 1130-330K-RC uses a radial drum core configuration. Verify mounting hole spacing and component height clearance on your PCB before substitution.

Q: Does the 1130-330K-RC meet environmental compliance requirements?

A: The 1130-330K-RC is ROHS3 compliant and REACH unaffected. Verify your application's specific regulatory requirements before final selection.

Q: What inductance tolerance should be assumed for circuit calculations?

A: The 1130-330K-RC specifies ±10% tolerance. Design circuits to accommodate this tolerance range for both components.
