Bourns 2107-V Equivalent & Substitute Parts

Part Overview

The Bourns 2107-V is a 33 µH unshielded toroidal inductor rated for 5 A with a maximum DC resistance of 29 mOhm. This through-hole component features a radial, vertical mounting configuration with operating temperature range from -55°C to 105°C. The 2107-V is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2107-V is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical inductance value (33 µH), tolerance (±15%), current rating (5 A), and maximum DC resistance (29 mOhm). The physical form factor—unshielded toroidal construction with radial, vertical mounting—and thermal operating range (-55°C to 105°C) are non-negotiable mechanical requirements. The 2107-V-RC qualifies as a direct substitute because it matches all specified parameters while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 2107-V-RC is the appropriate substitute for the obsolete 2107-V. Both parts are manufactured by Bourns Inc. within the 2100 series and maintain identical electrical specifications and physical dimensions. The 2107-V-RC offers two significant advantages: active product status ensures continued availability and manufacturing support, and ROHS3 compliance aligns with current regulatory requirements, whereas the original 2107-V is RoHS non-compliant. For new designs or production transitions, the 2107-V-RC provides equivalent performance with improved supply chain reliability and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 2107-V-RC be used as a direct replacement for the 2107-V in existing designs?

A: Yes. The 2107-V-RC is electrically and mechanically identical to the 2107-V across all specified parameters: 33 µH inductance, 5 A current rating, 29 mOhm maximum DC resistance, unshielded toroidal construction, and identical physical dimensions. No circuit modifications are required.

Q: What is the difference between the 2107-V and 2107-V-RC?

A: The primary differences are product status and compliance. The 2107-V is obsolete and RoHS non-compliant, while the 2107-V-RC is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 2107-V is supplied in standard packaging, while the 2107-V-RC is supplied in bulk packaging. Both maintain the same radial, vertical (open) form factor and through-hole mounting configuration.

Q: What parameters must match for a part to substitute for the 2107-V?

A: Critical parameters include inductance (33 µH), tolerance (±15%), current rating (5 A), maximum DC resistance (29 mOhm), unshielded toroidal construction, radial vertical mounting, and operating temperature range (-55°C to 105°C). Physical dimensions must also remain 0.860" diameter by 0.450" width.

Q: Is the 2107-V-RC suitable for new production designs?

A: Yes. The 2107-V-RC is an active product with current manufacturing support and ROHS3 compliance, making it the recommended choice for new designs requiring a 33 µH, 5 A toroidal inductor in this form factor.
