Bourns 2118-V Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 2118-V is a 330 µH unshielded toroidal inductor rated for 1.7 A with a maximum DC resistance of 230 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series. The 2118-V carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support, procurement continuity, and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2118-V is determined by strict equivalence across the following critical parameters:

• Inductance Value: 330 µH (±15% tolerance)
• Current Rating: 1.7 A minimum
• DC Resistance: 230 mOhm maximum
• Inductor Type: Toroidal configuration
• Shielding Classification: Unshielded
• Mounting Configuration: Through-hole, radial vertical orientation
• Physical Dimensions: 0.860" diameter × 0.450" width (21.84mm × 11.43mm)
• Operating Temperature Range: -55°C to 105°C

The 2118-V-RC meets all substitution criteria as a direct functional equivalent within the same 2100 series family, maintaining identical electrical specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The 2118-V-RC is the direct active equivalent for the obsolete 2118-V. Both components maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction lies in product lifecycle status and regulatory compliance:

The 2118-V carries obsolete designation with RoHS non-compliant status. The 2118-V-RC is an active product with ROHS3 compliance, providing regulatory alignment for new designs and improved long-term supply chain availability. Both components are manufactured by Bourns Inc. within the same 2100 series family and are mechanically and electrically interchangeable.

For applications requiring RoHS3 compliance or ongoing component availability, the 2118-V-RC is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part satisfies the functional specification.

Frequently Asked Questions (FAQ)

Q: Can the 2118-V-RC directly replace the 2118-V in existing designs?

A: Yes. The 2118-V-RC is electrically and mechanically identical to the 2118-V. Both components share the same inductance value (330 µH), current rating (1.7 A), DC resistance (230 mOhm), physical dimensions (0.860" Dia × 0.450" W), and operating temperature range (-55°C to 105°C). PCB layout and circuit performance remain unchanged.

Q: What is the primary reason to transition from 2118-V to 2118-V-RC?

A: The 2118-V is obsolete with RoHS non-compliant status. The 2118-V-RC is an active product with ROHS3 compliance, ensuring regulatory alignment and sustained supplier availability for new production and long-term support.

Q: Are there packaging differences between these parts?

A: The 2118-V is supplied in standard packaging, while the 2118-V-RC is supplied in bulk packaging. Both maintain identical component specifications and through-hole radial vertical mounting configuration. Packaging format does not affect electrical or mechanical performance.

Q: What inventory status should be considered for procurement?

A: The 2118-V has 963 pieces in stock (obsolete status). The 2118-V-RC has 1,380 pieces in stock (active status). For new designs and ongoing production, the 2118-V-RC provides superior supply chain continuity.

Q: Are there any compliance or certification differences?

A: The 2118-V is RoHS non-compliant. The 2118-V-RC is ROHS3 compliant. Both carry identical REACH Unaffected and EAR99 ECCN designations. For applications subject to RoHS3 requirements, the 2118-V-RC is the mandated selection.
