Bourns 2315-H 180µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2315-H is a 180 µH unshielded toroidal inductor rated for 4.8 A continuous current with a maximum DC resistance of 78 mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 2315-H is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Substitute parts must maintain identical electrical specifications and mechanical form factors to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 2315-H is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following criteria:

• Inductance value: 180 µH with ±15% tolerance
• Current rating: 4.8 A minimum
• DC resistance: 78 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
• Temperature range: -55°C to 105°C operation
• Test frequency: 1 kHz inductance measurement

The 2315-H-RC is a direct electrical and mechanical equivalent manufactured by Bourns Inc. within the same 2300 series product line. Both parts share identical core specifications, performance ratings, and form factors, enabling direct substitution in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The 2315-H-RC is the active production equivalent of the obsolete 2315-H. Both components are manufactured by Bourns Inc. and maintain identical electrical performance and mechanical compatibility. The 2315-H-RC offers the additional advantage of ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and production environments. The 2315-H-RC is available in bulk packaging, supporting both prototype and volume production requirements. Selection between these parts should be based on product status and regulatory compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 2315-H-RC directly replace the 2315-H in existing designs?

A: Yes. The 2315-H-RC is electrically and mechanically identical to the 2315-H. All electrical parameters, physical dimensions, and mounting characteristics are equivalent, enabling direct substitution without circuit modification or PCB redesign.

Q: What is the primary difference between the 2315-H and 2315-H-RC?

A: The 2315-H-RC is the active production part with ROHS3 compliance, while the 2315-H is obsolete and non-compliant. Both parts share identical inductance, current rating, DC resistance, core material, and form factor specifications.

Q: Are there packaging differences between these parts?

A: The 2315-H is supplied in standard packaging, while the 2315-H-RC is available in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Q: What parameters must remain constant for substitution?

A: Inductance (180 µH ±15%), current rating (4.8 A), DC resistance (78 mOhm max), core material (iron powder), shielding (unshielded), mounting type (through-hole), package configuration (radial horizontal), physical dimensions (1.280" diameter, 0.650" height), and operating temperature range (-55°C to 105°C) must all remain unchanged for direct substitution.

Q: Is the 2315-H-RC suitable for new product designs?

A: Yes. The 2315-H-RC is an active production part with ROHS3 compliance and is appropriate for new designs requiring a 180 µH, 4.8 A toroidal inductor with the specified electrical and mechanical characteristics.
