IHB3EB472K Equivalent & Substitute Parts

Part Overview

The IHB3EB472K is a 4.7 mH unshielded wirewound inductor manufactured by Vishay Dale, rated for 800 mA with a maximum DC resistance of 1.86 Ohm. This through-hole radial component is designed for applications requiring fixed inductance in compact form factors. The part is currently in stock with 1099 units available as new original inventory.

Substitute parts are identified based on matching electrical specifications (inductance value, current rating, DC resistance) and mechanical compatibility (through-hole radial mounting, vertical cylinder package).

Substitute Part Grouping Explanation

Substitution eligibility for the IHB3EB472K is determined by the following criteria:

• Inductance Value: Must be 4.7 mH (±10% tolerance acceptable)
• Current Rating: Must be equal to or greater than 800 mA
• DC Resistance: Must not exceed 1.86 Ohm maximum
• Mounting Configuration: Must be through-hole radial, vertical cylinder package
• Core Construction: Wirewound or drum core wirewound acceptable
• Shielding: Unshielded configuration

The substitute part 1130-472K-RC meets all substitution criteria with a current rating of 1 A (exceeding the 800 mA requirement) and identical DC resistance specification.

Engineering Selection Recommendations

The 1130-472K-RC from Bourns Inc. is a direct electrical and mechanical substitute for the IHB3EB472K. Selection between these parts should be based on:

• Availability: The 1130-472K-RC has higher inventory (2870 units) compared to the IHB3EB472K (1099 units)
• Product Status: The 1130-472K-RC is listed as Active
• Compliance: The 1130-472K-RC carries ROHS3 compliance and REACH Unaffected status, providing regulatory assurance for applications requiring these certifications
• Current Margin: The 1 A rating of the 1130-472K-RC provides a 200 mA margin above the 800 mA requirement, offering additional operational headroom

Both parts are suitable for through-hole assembly and occupy identical package footprints.

Frequently Asked Questions (FAQ)

Q: Can the 1130-472K-RC replace the IHB3EB472K in existing designs?

A: Yes. Both parts share identical inductance (4.7 mH), DC resistance (1.86 Ohm max), and package configuration (through-hole radial, vertical cylinder). The 1130-472K-RC has a higher current rating (1 A vs. 800 mA), making it electrically compatible for the same application space.

Q: What is the significance of the higher current rating on the substitute part?

A: The 1130-472K-RC is rated for 1 A compared to the 800 mA rating of the IHB3EB472K. This provides a 200 mA safety margin and indicates the substitute part can handle higher current loads without saturation or thermal stress.

Q: Are the physical dimensions identical?

A: Both parts use the same radial, vertical cylinder package configuration. The 1130-472K-RC specifies dimensions of 1.100" diameter (27.94 mm) and 0.840" seated height (21.34 mm), confirming PCB footprint compatibility.

Q: What compliance certifications apply to the substitute part?

A: The 1130-472K-RC is ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for applications in restricted substance directives.

Q: Is the core material difference significant?

A: The IHB3EB472K uses wirewound construction, while the 1130-472K-RC uses drum core wirewound construction. Both are unshielded and deliver the same electrical performance at the specified inductance and current ratings.
