Bourns 2311-H Equivalent & Substitute Parts

Part Overview

The Bourns 2311-H is a 68 µH unshielded toroidal inductor rated for 7.7 A with a maximum DC resistance of 30mOhm. This through-hole component features an iron powder core and operates across a temperature range of -55°C to 105°C. The 2311-H is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The 2311-H-RC serves as a direct substitute for the 2311-H based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following parameters:

• Inductance value: 68 µH with ±15% tolerance
• Current rating: 7.7 A minimum
• DC resistance: 30mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Physical dimensions: 1.280" diameter, 0.650" maximum seated height
• Operating temperature range: -55°C to 105°C

The 2311-H-RC maintains all electrical and mechanical characteristics of the original part while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 2311-H-RC is the direct equivalent for the obsolete 2311-H. Selection of the 2311-H-RC is supported by:

• Identical electrical specifications (inductance, current rating, DC resistance)
• Identical mechanical form factor and mounting configuration
• Active product status ensuring ongoing availability
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Maintained REACH unaffected status and EAR99 classification

For applications requiring the 68 µH, 7.7 A toroidal inductor with through-hole radial mounting, the 2311-H-RC provides full functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2311-H-RC be used as a direct replacement for the 2311-H?

A: Yes. The 2311-H-RC maintains identical inductance (68 µH), current rating (7.7 A), DC resistance (30mOhm maximum), core material (iron powder), shielding (unshielded), and physical dimensions (1.280" diameter, 0.650" maximum height). Through-hole radial mounting is identical. No circuit modifications are required.

Q: What is the difference between the 2311-H and 2311-H-RC?

A: The primary differences are product status and compliance. The 2311-H is obsolete and RoHS non-compliant. The 2311-H-RC is active and ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Does packaging differ between these parts?

A: The 2311-H is supplied in standard packaging, while the 2311-H-RC is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: Are there any temperature or operating condition differences?

A: No. Both parts operate across the identical temperature range of -55°C to 105°C with the same inductance frequency test specification of 1 kHz.

Q: What compliance certifications apply to the 2311-H-RC?

A: The 2311-H-RC is ROHS3 compliant and REACH unaffected. It carries the same EAR99 export classification and HTSUS code (8504.50.4000) as the original part.
