Bourns 2319-V 390µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2319-V is a 390 µH unshielded toroidal inductor rated for 5 A continuous current with a maximum DC resistance of 72 mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2319-V is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The substitute part 2319-V-RC provides functional equivalence while maintaining active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2319-V with the 2319-V-RC is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical selection criteria: 390 µH inductance at ±15% tolerance, 5 A current rating, 72 mOhm maximum DC resistance, iron powder core construction, unshielded configuration, through-hole mounting, and radial vertical package orientation. Physical dimensions are identical at 1.280" diameter × 0.650" width. Operating temperature range and inductance test frequency are matched. The substitution is valid based on these parameters alone.

Parameter Comparison

Engineering Selection Recommendations

The 2319-V-RC is the direct active equivalent for the obsolete 2319-V. Selection of the 2319-V-RC is supported by complete electrical and mechanical parameter equivalence. The 2319-V-RC maintains active product status, ensuring long-term availability and supply chain continuity. The 2319-V-RC achieves ROHS3 compliance, whereas the 2319-V is non-compliant. For applications subject to RoHS requirements, the 2319-V-RC is the appropriate selection. Both parts carry identical REACH Unaffected and EAR99 ECCN classifications.
