Bourns 2111-H 68µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2111-H is a 68 µH unshielded toroidal inductor rated for 3.3 A with a maximum DC resistance of 67mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series. The 2111-H has reached obsolete status, making identification of suitable substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2111-H is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 68 µH with ±15% tolerance
• Current rating: 3.3 A minimum
• DC resistance: 67mOhm maximum
• Shielding configuration: Unshielded
• Core type: Toroidal
• Mounting: Through hole, radial horizontal orientation
• Physical dimensions: 0.860" diameter, 0.450" maximum seated height
• Operating temperature: -55°C to 105°C
• Test frequency: 1 kHz

The 2111-H-RC meets all these criteria and is classified as a direct substitute within the same 2100 series family.

Parameter Comparison

Engineering Selection Recommendations

The 2111-H-RC is the direct functional equivalent of the 2111-H and serves as the primary substitute for this obsolete component. Both parts are manufactured by Bourns Inc. within the 2100 series and maintain identical electrical specifications and physical dimensions.

The 2111-H-RC offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The substitute also provides ROHS3 compliance, whereas the original 2111-H is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 export classification.

Selection between these parts should be based on procurement requirements and regulatory compliance needs. The 2111-H-RC is recommended for new designs and ongoing production where RoHS3 compliance is required or preferred.

Frequently Asked Questions (FAQ)

Q: Can the 2111-H-RC be used as a direct replacement for the 2111-H?

A: Yes. The 2111-H-RC is electrically and mechanically equivalent to the 2111-H. Both components share identical inductance (68 µH), current rating (3.3 A), DC resistance (67mOhm max), physical dimensions (0.860" diameter, 0.450" height), and operating temperature range (-55°C to 105°C).

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

A: The 2111-H-RC is the active production variant with ROHS3 compliance, while the 2111-H is obsolete and RoHS non-compliant. The 2111-H-RC also differs in packaging (bulk versus standard) and has higher inventory availability.

Q: Are there any dimensional or mounting differences?

A: No. Both parts use identical through-hole radial horizontal mounting with the same 0.860" diameter and 0.450" maximum seated height. PCB layout and mechanical integration are identical.

Q: Does the substitute part maintain the same inductance tolerance?

A: Yes. Both the 2111-H and 2111-H-RC maintain ±15% inductance tolerance at 1 kHz test frequency.

Q: What is the impact of RoHS3 compliance on part selection?

A: RoHS3 compliance is a regulatory requirement in many markets. The 2111-H-RC meets this standard, while the 2111-H does not. For applications subject to RoHS regulations, the 2111-H-RC is the appropriate choice.
