Bourns 2110-H 56µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2110-H is a 56 µH unshielded toroidal inductor rated for 3.4 A continuous current with a maximum DC resistance of 60 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series inductor family. The 2110-H has reached obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2110-H is determined by strict equivalence across the following electrical and mechanical parameters:

Inductance value must match at 56 µH with ±15% tolerance. Current rating must be rated for minimum 3.4 A continuous operation. DC resistance must not exceed 60 mOhm maximum. The component must be a toroidal, unshielded inductor with through-hole mounting in radial, horizontal (open) package configuration. Physical dimensions must conform to 0.860" diameter (21.84 mm) and 0.450" maximum seated height (11.43 mm). Operating temperature range must span -55°C to 105°C minimum.

The 2110-H-RC meets all these criteria and serves as the direct functional equivalent for the obsolete 2110-H.

Parameter Comparison

Engineering Selection Recommendations

The 2110-H-RC is the direct active equivalent for the obsolete 2110-H. All electrical and mechanical parameters are identical. The 2110-H-RC carries ROHS3 compliance status, whereas the original 2110-H is RoHS non-compliant. Both components maintain REACH Unaffected status and EAR99 export classification. The 2110-H-RC is available in bulk packaging and maintains higher current inventory levels, supporting reliable procurement for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the 2110-H-RC be used as a direct replacement for the 2110-H?

A: Yes. The 2110-H-RC is electrically and mechanically identical to the 2110-H across all specified parameters: 56 µH inductance, 3.4 A current rating, 60 mOhm maximum DC resistance, toroidal unshielded construction, through-hole radial horizontal mounting, and identical physical dimensions. The primary difference is product status and RoHS compliance.

Q: What is the difference between the 2110-H and 2110-H-RC?

A: The 2110-H is obsolete with RoHS non-compliant status. The 2110-H-RC is an active product with ROHS3 compliance. Electrical specifications and physical form factor are identical. The 2110-H-RC is supplied in bulk packaging.

Q: Are there any compatibility concerns when substituting the 2110-H-RC for the 2110-H?

A: No compatibility concerns exist. The components are pin-compatible, dimensionally identical, and electrically equivalent. PCB layouts and circuit designs require no modification.

Q: What packaging options are available?

A: The 2110-H was supplied in standard packaging. The 2110-H-RC is available in bulk packaging format.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both components meet identical electrical specifications and operating parameters.
