Bourns 2117-H Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 2117-H is a 270 µH unshielded toroidal inductor rated for 1.8 A continuous current with a maximum DC resistance of 210 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is part of the 2100 series inductor family. The 2117-H carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The 2117-H-RC serves as a direct substitute for the obsolete 2117-H based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Inductance value: 270 µH at 1.8 A
• Inductance tolerance: ±15%
• DC resistance: 210 mOhm maximum
• Current rating: 1.8 A continuous
• Physical form factor: Toroidal, unshielded, radial horizontal orientation
• Through-hole mounting compatibility
• Operating temperature range: -55°C to 105°C
• Inductance measurement frequency: 1 kHz

The 2117-H-RC maintains all electrical performance characteristics and physical dimensions of the original part while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 2117-H-RC is the direct functional equivalent for the obsolete 2117-H. Selection of the 2117-H-RC is supported by:

• Identical electrical specifications across all measured parameters
• Matching physical dimensions and mounting interface
• Active product status ensuring long-term availability
• ROHS3 compliance certification, meeting current environmental regulations
• Equivalent REACH and ECCN classifications

For applications currently using the 2117-H, direct substitution with the 2117-H-RC requires no circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 2117-H-RC be used as a direct replacement for the 2117-H?

A: Yes. The 2117-H-RC is electrically and mechanically identical to the 2117-H. All electrical parameters, physical dimensions, and mounting characteristics are equivalent. No circuit or layout changes are required.

Q: What is the difference between the 2117-H and 2117-H-RC?

A: The primary differences are product status and compliance certifications. The 2117-H is obsolete, while the 2117-H-RC is active. The 2117-H-RC meets ROHS3 compliance standards, whereas the 2117-H does not. Both parts share identical inductance, current rating, DC resistance, and physical form factor.

Q: Are there packaging differences between these parts?

A: The 2117-H-RC is supplied in bulk packaging, while the 2117-H uses standard packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Q: What are the critical parameters for inductor substitution?

A: For the 2117-H family, substitution eligibility is determined by inductance value (270 µH), inductance tolerance (±15%), current rating (1.8 A), DC resistance (210 mOhm maximum), toroidal unshielded form factor, and through-hole radial horizontal mounting compatibility.

Q: Is the 2117-H-RC suitable for applications requiring RoHS compliance?

A: Yes. The 2117-H-RC carries ROHS3 compliance certification, making it suitable for applications with RoHS requirements. The obsolete 2117-H does not meet RoHS standards.

Q: What is the operating temperature range for both parts?

A: Both the 2117-H and 2117-H-RC operate across -55°C to 105°C, providing equivalent thermal performance across industrial and commercial temperature ranges.
