Bourns 2105-H 22µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2105-H is a 22 µH unshielded toroidal inductor rated for 7 A continuous current with a maximum DC resistance of 15 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series. The 2105-H carries an obsolete product status, making identification of suitable substitutes essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The 2105-H-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Inductance value: 22 µH with ±15% tolerance
• Current rating: 7 A minimum
• DC resistance: 15 mOhm maximum
• Toroidal type with unshielded construction
• Through-hole mounting with radial, horizontal (open) package configuration
• Physical dimensions: 0.860" diameter and 0.450" maximum seated height
• Operating temperature range: -55°C to 105°C

The 2105-H-RC maintains all specified electrical and mechanical characteristics, differing only in product status (active versus obsolete) and packaging format (bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The 2105-H-RC is the appropriate substitute for the obsolete 2105-H. Both components share identical electrical specifications and mechanical form factors, ensuring direct compatibility in circuit applications. The primary distinction lies in product lifecycle status and regulatory compliance.

The 2105-H carries obsolete designation, limiting long-term availability and support. The 2105-H-RC maintains active product status with current manufacturing support from Bourns Inc.

Regarding compliance: the 2105-H is RoHS non-compliant, while the 2105-H-RC achieves ROHS3 compliance. For applications subject to RoHS directives or procurement policies requiring compliant components, the 2105-H-RC is the mandated selection. Both components maintain REACH unaffected status and carry EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 2105-H-RC replace the 2105-H in existing designs?

A: Yes. The 2105-H-RC provides identical electrical performance and mechanical fit. No circuit modifications or PCB layout changes are required.

Q: What is the difference between the 2105-H and 2105-H-RC?

A: The components are electrically and mechanically identical. The 2105-H-RC differs in product status (active versus obsolete), packaging format (bulk), and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: Does the packaging difference affect component performance?

A: No. Packaging format (bulk versus standard) does not affect electrical characteristics or mechanical compatibility. Both variants are identical toroidal inductors with radial, horizontal (open) configuration.

Q: Are there any thermal or current rating differences?

A: No. Both the 2105-H and 2105-H-RC maintain identical current ratings of 7 A and operate across the same temperature range of -55°C to 105°C.

Q: Which part should be specified for new designs?

A: The 2105-H-RC should be specified for new designs due to its active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.
