Bourns 2312-V Fixed Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 2312-V is a 100 µH unshielded toroidal inductor rated for 7 A continuous current with a maximum DC resistance of 37 mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2312-V is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The primary substitute maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 2312-V is determined by strict equivalence across the following critical parameters:

  • Inductance value: 100 µH with ±15% tolerance
  • Current rating: 7 A minimum
  • DC resistance: 37 mOhm maximum
  • Core material: Iron powder
  • Shielding configuration: Unshielded
  • Mounting type: Through hole
  • Package geometry: Radial, vertical (open) orientation
  • Physical dimensions: 1.280" diameter x 0.650" width
  • Operating temperature range: -55°C to 105°C

The Bourns 2312-V-RC qualifies as a direct substitute because it maintains identical electrical performance and mechanical form factor across all specified parameters. The substitution is valid regardless of packaging format differences (tape/reel versus bulk).

Engineering Selection Recommendations

The Bourns 2312-V-RC is the appropriate selection for new designs and production continuity. While both parts deliver identical electrical and mechanical performance, the 2312-V-RC offers two distinct advantages:

  1. Active product status ensures long-term availability and manufacturing support from Bourns Inc.
  2. ROHS3 compliance satisfies regulatory requirements for products subject to Restriction of Hazardous Substances directives, whereas the original 2312-V carries non-compliant status.

For applications where RoHS compliance is not mandated, both parts remain functionally equivalent. However, the transition to 2312-V-RC eliminates obsolescence risk and aligns with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the 2312-V-RC be used as a direct replacement for the 2312-V in existing assemblies?

A: Yes. The 2312-V-RC maintains identical inductance (100 µH ±15%), current rating (7 A), DC resistance (37 mOhm max), core material (iron powder), and physical dimensions (1.280" Dia x 0.650" W). Through-hole mounting and radial vertical orientation are unchanged. No circuit modifications or PCB redesign is required.

Q: What is the difference between the 2312-V and 2312-V-RC?

A: The electrical and mechanical specifications are identical. The primary differences are product status (2312-V is obsolete; 2312-V-RC is active) and RoHS compliance (2312-V is non-compliant; 2312-V-RC is ROHS3 compliant). Packaging format may differ (bulk versus tape/reel), but this does not affect component performance.

Q: Are there any temperature or frequency limitations when substituting the 2312-V-RC?

A: No. Both parts operate across -55°C to 105°C and are tested at 1 kHz inductance frequency. Operating conditions remain unchanged.

Q: Does the packaging format (bulk versus tape/reel) affect electrical performance?

A: No. Packaging format is a logistics consideration only. The 2312-V-RC in bulk packaging delivers identical electrical and mechanical performance to tape/reel configurations of the same part number.

Q: Is RoHS3 compliance required for my application?

A: RoHS compliance is mandated by regulatory frameworks in specific regions and industries. Verify your application's compliance requirements. If RoHS3 compliance is necessary, the 2312-V-RC is the required selection. If not mandated, both parts are functionally equivalent.
