IHB3EB471K Equivalent & Substitute Parts

Part Overview

The IHB3EB471K is a 470 µH unshielded wirewound inductor manufactured by Vishay Dale, rated for 2.6 A continuous current with a maximum DC resistance of 187 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in power conversion, filtering, and signal conditioning circuits. With 1002 units currently in stock, alternative parts may be required due to supply constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

The 1130-471K-RC from Bourns Inc. qualifies as a direct substitute based on the following critical parameters:

• Inductance Value: Both parts specify 470 µH, meeting the core functional requirement
• DC Resistance: Both maintain 187 mOhm maximum, ensuring equivalent power loss characteristics
• Shielding Configuration: Both are unshielded wirewound inductors
• Mounting Interface: Both use through-hole radial vertical cylinder packaging
• Current Rating: The substitute part is rated for 4 A, which exceeds the main part's 2.6 A requirement, providing design margin

The substitute part operates within the same inductance tolerance (±10%) and maintains compatibility with standard PCB footprints for radial through-hole components.

Parameter Comparison

Engineering Selection Recommendations

The 1130-471K-RC is suitable as a direct substitute for the IHB3EB471K in applications where the following conditions are met:

• Circuit design accommodates the higher current rating (4 A vs. 2.6 A)
• PCB layout supports the radial vertical cylinder footprint
• Operating environment falls within -55°C to 105°C range
• ROHS3 compliance is required or acceptable for the application

The substitute part's active product status and higher current rating provide improved availability and design margin for new designs or production continuity scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 1130-471K-RC replace the IHB3EB471K in existing designs?

A: Yes, provided the PCB footprint accommodates the radial vertical cylinder package and the circuit operates within the specified current and temperature ranges. The identical inductance value (470 µH) and DC resistance (187 mOhm) ensure electrical equivalence.

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

A: The main difference is the current rating: the substitute part is rated for 4 A versus the original part's 2.6 A. Both maintain identical inductance and DC resistance specifications.

Q: Are there any compliance differences between the parts?

A: The 1130-471K-RC is ROHS3 compliant and REACH unaffected. Compliance status for the IHB3EB471K is not specified in available documentation.

Q: Will the substitute part fit the same PCB layout?

A: Both parts use radial vertical cylinder through-hole packaging. Physical dimensions should be verified against the specific PCB footprint, as the Bourns part specifies 1.100" diameter and 0.840" maximum seated height.

Q: Is the substitute part suitable for high-frequency applications?

A: Self-resonant frequency data is not provided for either part. Application-specific frequency response requirements should be evaluated independently.
