Bourns 2108-V Fixed Toroidal Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 2108-V is a 39 µH unshielded toroidal inductor rated for 4.8 A with a maximum DC resistance of 32 mOhm. This through-hole component is designed for radial, vertical mounting in applications requiring fixed inductance values with moderate current handling. The 2108-V carries an obsolete product status, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2108-V is determined by strict equivalence across the following critical parameters:

• Inductance Value: 39 µH (±15% tolerance)
• Current Rating: 4.8 A minimum
• DC Resistance: 32 mOhm maximum
• Shielding Configuration: Unshielded
• Mounting Type: Through Hole
• Package / Case: Radial, Vertical (Open)
• Operating Temperature Range: -55°C to 105°C
• Physical Dimensions: 0.860" Dia × 0.450" W

The 2108-V-RC meets all electrical and mechanical parameters required for direct substitution. Both parts share the same base product number (2108) and series designation (2100), confirming functional equivalence within the Bourns toroidal inductor family.

Parameter Comparison

Engineering Selection Recommendations

The 2108-V-RC is the direct active equivalent for the obsolete 2108-V. Selection of the 2108-V-RC is appropriate for new designs and production continuity due to its active product status and ROHS3 compliance. The 2108-V-RC maintains identical electrical specifications and physical form factor, ensuring drop-in compatibility in existing PCB layouts and circuit designs.

For applications subject to RoHS regulatory requirements, the 2108-V-RC is the mandated choice. The transition from the non-compliant 2108-V to the ROHS3-compliant 2108-V-RC presents no functional or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2108-V-RC be used as a direct replacement for the 2108-V?

A: Yes. The 2108-V-RC is electrically and mechanically equivalent to the 2108-V across all specified parameters, including inductance, current rating, DC resistance, shielding, mounting type, package configuration, and operating temperature range.

Q: What is the primary difference between the 2108-V and 2108-V-RC?

A: The 2108-V is obsolete and RoHS non-compliant, while the 2108-V-RC is an active product with ROHS3 compliance. Both parts are functionally identical.

Q: Are there any physical dimension differences between these parts?

A: No. Both the 2108-V and 2108-V-RC share identical physical dimensions of 0.860" diameter × 0.450" width (21.84 mm × 11.43 mm), ensuring compatibility with existing PCB footprints and mounting hardware.

Q: What packaging options are available for the 2108-V-RC?

A: The 2108-V-RC is supplied in bulk packaging. Verify packaging requirements with your procurement specifications before ordering.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 2108-V and 2108-V-RC operate across the identical temperature range of -55°C to 105°C.

Q: Does the inductance tolerance differ between these parts?

A: No. Both parts maintain an inductance tolerance of ±15% at the 1 kHz test frequency.
