Bourns 2317-V 270µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2317-V is a 270µH unshielded toroidal inductor rated for 5.5A continuous current with 60mOhm maximum DC resistance. This through-hole component features an iron powder core and operates across the -55°C to 105°C temperature range. The 2317-V is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The 2317-V-RC provides a direct functional equivalent with improved product status and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2317-V is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

Electrical Parameters (Non-negotiable):

• Inductance value: 270µH
• Inductance tolerance: ±15%
• Current rating: 5.5A minimum
• DC resistance: 60mOhm maximum
• Core material: Iron Powder
• Shielding configuration: Unshielded

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial, Vertical (Open)
• Physical dimensions: 1.280" Dia × 0.650" W (32.51mm × 16.51mm)

Environmental Parameters (Non-negotiable):

• Operating temperature range: -55°C to 105°C minimum

The 2317-V-RC meets all substitution criteria as a direct equivalent from the same manufacturer (Bourns Inc.) within the same 2300 series family.

Engineering Selection Recommendations

The 2317-V-RC is the direct equivalent for the obsolete 2317-V. Selection of the 2317-V-RC is based on the following engineering factors:

Product Status: The 2317-V is classified as obsolete, creating supply chain risk. The 2317-V-RC maintains active product status with confirmed inventory availability (1154 pcs), ensuring long-term sourcing capability.

Regulatory Compliance: The 2317-V-RC achieves ROHS3 compliance, whereas the 2317-V is RoHS non-compliant. For applications subject to RoHS directives or customer requirements, the 2317-V-RC satisfies modern regulatory standards.

Electrical and Mechanical Equivalence: All critical electrical parameters (inductance, current rating, DC resistance, core material) and mechanical specifications (dimensions, mounting type, package configuration) are identical between the two parts.

Environmental Specifications: Both parts operate across the identical -55°C to 105°C temperature range, ensuring thermal compatibility in existing designs.

Packaging Availability: The 2317-V-RC is available in bulk packaging, supporting production requirements and inventory management.

Frequently Asked Questions (FAQ)

Q: Can the 2317-V-RC be used as a direct replacement for the 2317-V in existing designs?

A: Yes. The 2317-V-RC is electrically and mechanically identical to the 2317-V across all specified parameters. PCB footprint, lead configuration, and mounting orientation are unchanged. No circuit redesign is required.

Q: What is the difference between the 2317-V and 2317-V-RC?

A: The primary differences are product status and regulatory compliance. The 2317-V is obsolete and RoHS non-compliant. The 2317-V-RC is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts feature identical inductance (270µH), current rating (5.5A), DC resistance (60mOhm max), core material (iron powder), and operating temperature range (-55°C to 105°C). Thermal and electrical performance are equivalent.

Q: What packaging options are available for the 2317-V-RC?

A: The 2317-V-RC is supplied in bulk packaging. The 2317-V packaging specification was not provided in the original documentation.

Q: Is the 2317-V-RC suitable for new designs?

A: Yes. The 2317-V-RC is an active product with modern regulatory compliance (ROHS3). It is appropriate for both replacement of obsolete 2317-V units and new design implementations.

Q: Are there any compatibility concerns with PCB assembly equipment?

A: No. Both parts use identical through-hole mounting with radial, vertical (open) package configuration. Standard PCB assembly processes for through-hole components apply without modification.
