Bourns 2112-H Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 2112-H is a 100 µH unshielded toroidal inductor rated for 2.4 A continuous current with a maximum DC resistance of 130 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series. The 2112-H carries an 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 2112-H is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 100 µH
• Inductance tolerance: ±15%
• Current rating: 2.4 A minimum
• DC resistance: 130 mOhm maximum
• Type: Toroidal
• Shielding: Unshielded
• Mounting type: Through Hole
• Package configuration: Radial, Horizontal (Open)
• Physical dimensions: 0.860" diameter, 0.450" maximum seated height
• Operating temperature range: -55°C to 105°C

The 2112-H-RC meets all these criteria and is classified as a direct substitute. Both parts share identical electrical specifications and mechanical form factors, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 2112-H-RC is the direct functional equivalent of the 2112-H. Both parts are manufactured by Bourns Inc. within the 2100 series and maintain identical electrical and mechanical specifications. The 2112-H-RC is the preferred selection for new designs and ongoing procurement due to its active product status and ROHS3 compliance. The 2112-H, classified as obsolete, should be replaced with the 2112-H-RC in applications where regulatory compliance and long-term component availability are required. Both parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the 2112-H-RC be used as a direct replacement for the 2112-H?

A: Yes. The 2112-H-RC is electrically and mechanically identical to the 2112-H. All electrical parameters (inductance, current rating, DC resistance) and physical dimensions are equivalent. The primary difference is product status and RoHS compliance.

Q: What is the difference between the 2112-H and 2112-H-RC?

A: The 2112-H-RC is the active production variant with ROHS3 compliance, while the 2112-H is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 2112-H is supplied in standard packaging, while the 2112-H-RC is supplied in bulk packaging. Both maintain the same radial, horizontal (open) form factor and through-hole mounting configuration.

Q: What are the critical parameters for substitution?

A: Substitution is valid when inductance (100 µH ±15%), current rating (2.4 A), DC resistance (130 mOhm max), toroidal type, unshielded configuration, through-hole mounting, and physical dimensions (0.860" diameter, 0.450" max height) are maintained.

Q: Is the 2112-H-RC suitable for new designs?

A: Yes. The 2112-H-RC is the recommended choice for new designs due to its active product status and ROHS3 compliance.
