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

Part Overview

The Bourns 2319-H is a 390µH unshielded toroidal inductor rated for 5A continuous current with a maximum DC resistance of 72mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2319-H is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications requiring this inductance value and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2319-H is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 390 µH
• Inductance tolerance: ±15%
• Current rating: 5 A minimum
• DC resistance: 72 mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting: Through hole, radial horizontal orientation
• Physical dimensions: 1.280" diameter, 0.650" maximum seated height
• Operating temperature range: -55°C to 105°C

The 2319-H-RC meets all these criteria and is classified as an active product, making it the direct functional equivalent for applications currently using the obsolete 2319-H.

Parameter Comparison

Engineering Selection Recommendations

The 2319-H-RC is the direct equivalent for applications currently specified with the Bourns 2319-H. Both parts share identical electrical and mechanical specifications within the 2300 series toroidal inductor family. The primary distinction is product status: the 2319-H is obsolete while the 2319-H-RC is active production.

For new designs or component refresh cycles, the 2319-H-RC is the appropriate selection. The 2319-H-RC additionally provides ROHS3 compliance, whereas the original 2319-H is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 2319-H-RC be used as a direct replacement for the 2319-H?

A: Yes. The 2319-H-RC is electrically and mechanically identical to the 2319-H across all specified parameters: 390µH inductance, 5A current rating, 72mOhm maximum DC resistance, iron powder core, unshielded configuration, and through-hole radial horizontal mounting. Physical dimensions and operating temperature range are identical.

Q: What is the difference between the 2319-H and 2319-H-RC?

A: The primary differences are product status and regulatory compliance. The 2319-H is obsolete; the 2319-H-RC is active production. The 2319-H-RC is ROHS3 compliant, while the 2319-H is RoHS non-compliant. All electrical and mechanical specifications are equivalent.

Q: Are there packaging differences between these parts?

A: The 2319-H is supplied in standard packaging, while the 2319-H-RC is supplied in bulk packaging. Both maintain identical component specifications and physical form factor.

Q: What inventory status should be considered when selecting between these parts?

A: The 2319-H-RC is the recommended selection for new procurement due to active production status. The 2319-H remains available in limited inventory (934 pieces) but is classified as obsolete. The 2319-H-RC has higher current inventory availability (1139 pieces).

Q: Are there any application restrictions when substituting the 2319-H-RC for the 2319-H?

A: No application restrictions exist. Both parts operate identically across the -55°C to 105°C temperature range and maintain the same inductance tolerance, current rating, and DC resistance specifications. Direct substitution is valid for all applications.
