Bourns 2112-V 100µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2112-V is a 100µH unshielded toroidal inductor rated for 2.4A continuous current with a maximum DC resistance of 130mOhm. This through-hole component is designed for radial, vertical mounting in applications requiring fixed inductance values with moderate current handling capability. The 2112-V carries an obsolete product status, making identification of active equivalent parts essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The 2112-V-RC qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution validity is determined by the following criteria:

• Inductance value and tolerance match exactly (100µH ±15%)
• Current rating is equivalent (2.4A)
• DC resistance specification is identical (130mOhm Max)
• Shielding configuration matches (Unshielded)
• Physical package and mounting type are identical (Radial, Vertical through-hole)
• Operating temperature range is the same (-55°C to 105°C)
• Core material and type are equivalent (Toroidal)

The 2112-V-RC maintains full electrical and mechanical compatibility with the obsolete 2112-V, differing only in packaging format (Bulk vs. standard) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 2112-V-RC is the direct equivalent for the obsolete 2112-V. Selection of the 2112-V-RC is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance, addressing regulatory requirements for new designs and manufacturing
• Identical electrical specifications eliminating circuit redesign requirements
• Matching mechanical form factor enabling direct board-level substitution
• Equivalent environmental ratings maintaining performance across the specified operating temperature range

For applications requiring RoHS non-compliant components, the original 2112-V remains available in limited inventory (1062 pieces). For new designs or ongoing production requiring regulatory compliance, the 2112-V-RC is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 2112-V-RC be used as a direct replacement for the 2112-V in existing designs?

A: Yes. The 2112-V-RC is electrically and mechanically identical to the 2112-V. All electrical parameters (inductance, current rating, DC resistance, operating temperature) and physical dimensions match exactly. No circuit modifications or board redesign are required.

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

A: The primary differences are product status and packaging. The 2112-V is obsolete with RoHS non-compliant status. The 2112-V-RC is an active product with ROHS3 compliance and is supplied in bulk packaging. Electrical and mechanical specifications are identical.

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

A: Yes. The 2112-V-RC is an active product with ROHS3 compliance, making it appropriate for new designs. The active status ensures ongoing availability and supply chain support.

Q: Are there any compatibility concerns when substituting the 2112-V-RC for the 2112-V?

A: No compatibility concerns exist. The components are pin-compatible, dimensionally identical, and electrically equivalent. The through-hole radial mounting configuration is unchanged.

Q: What is the inductance tolerance for both parts?

A: Both the 2112-V and 2112-V-RC have an inductance tolerance of ±15%, measured at 1 kHz.

Q: What is the maximum continuous current rating?

A: Both parts are rated for 2.4A continuous current with a maximum DC resistance of 130mOhm.
