IHB2EB271K Equivalent & Substitute Parts

Part Overview

The IHB2EB271K is a 270 µH unshielded wirewound inductor manufactured by Vishay Dale, rated for 2.1 A continuous current with a maximum DC resistance of 213 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in compact form factors. Substitute parts are identified based on matching electrical specifications (inductance value, current rating, DC resistance) and mechanical compatibility (package type, mounting configuration, physical dimensions).

Substitute Part Grouping Explanation

Substitution eligibility for the IHB2EB271K is determined by the following criteria:

• Inductance Value: Must be 270 µH (±10% tolerance acceptable)
• Current Rating: Minimum 2.0 A (the main part is rated 2.1 A; substitutes rated at or above 2.0 A are acceptable)
• DC Resistance: Maximum 213 mOhm (equal or lower values maintain performance)
• Shielding Configuration: Unshielded (matching electromagnetic isolation characteristics)
• Mounting Type: Through Hole (radial, vertical cylinder configuration)
• Operating Temperature Range: Compatible with -55°C to 105°C or broader range

The 1120-271K-RC from Bourns Inc. meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1120-271K-RC is suitable as a direct substitute for the IHB2EB271K based on the following factors:

• Electrical Equivalence: Both components provide 270 µH inductance with identical maximum DC resistance of 213 mOhm, ensuring equivalent circuit performance.
• Current Capacity: The 1120-271K-RC is rated for 2.0 A, which is 95% of the main part's 2.1 A rating. This is acceptable for applications where the load current does not exceed 2.0 A.
• Mechanical Compatibility: Identical package configuration (radial, vertical cylinder through-hole) ensures PCB footprint compatibility.
• Compliance Status: The 1120-271K-RC is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.
• Product Status: The 1120-271K-RC is listed as Active, ensuring continued availability and support.

For applications requiring the full 2.1 A rating, verify that the substitute's 2.0 A maximum does not constrain system performance.

Frequently Asked Questions (FAQ)

Q: Can the 1120-271K-RC replace the IHB2EB271K in all applications?

A: The 1120-271K-RC is electrically and mechanically compatible with the IHB2EB271K for applications operating at or below 2.0 A. If your circuit requires the full 2.1 A rating, the substitute may not be suitable.

Q: Are the physical dimensions identical?

A: Both components use radial, vertical cylinder through-hole packages. The 1120-271K-RC has a diameter of 0.810" (20.57mm) and seated height of 0.840" (21.34mm). Verify that the IHB2EB271K dimensions match before substitution.

Q: What is the tolerance difference between these parts?

A: The 1120-271K-RC specifies ±10% inductance tolerance. The IHB2EB271K tolerance is not provided in the available data. Both parts deliver 270 µH nominal inductance.

Q: Are there any compliance or regulatory differences?

A: The 1120-271K-RC is ROHS3 compliant and REACH unaffected. Compliance status for the IHB2EB271K is not specified. Verify compliance requirements for your application before substitution.

Q: What is the difference between drum core and standard wirewound construction?

A: The 1120-271K-RC uses drum core ferrite construction, while the IHB2EB271K construction type is not specified. Both deliver the same electrical performance for this inductance value and current rating.
