Bourns 9220-26 910µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9220-26 is a 910 µH unshielded drum core wirewound inductor rated for 79 mA with a maximum DC resistance of 15.8Ω. Designed for through-hole axial mounting, this component operates across the temperature range of -55°C to 105°C. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, repair, and redesign applications where this inductor specification remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9220-26 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 910 µH with ±5% tolerance
• Current Rating: Minimum 79 mA (substitute must support or exceed this specification)
• DC Resistance: Maximum 15.8Ω
• Shielding Configuration: Unshielded
• Operating Temperature Range: -55°C to 105°C
• Mounting and Package: Through-hole axial configuration

The API Delevan 2500-26J meets these substitution criteria. While it employs a molded core construction (versus the original drum core design) and operates at a different test frequency, it maintains electrical equivalence across all critical parameters required for functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2500-26J serves as a direct functional substitute for the obsolete Bourns 9220-26. Both components are RoHS non-compliant and REACH unaffected, maintaining equivalent compliance posture. The substitute part carries active product status with current inventory availability, whereas the original is obsolete.

The 2500-26J provides a higher current rating (91 mA versus 79 mA), which represents a design margin improvement without introducing incompatibility. Physical dimensions differ slightly (0.240" diameter × 0.740" length versus 0.190" diameter × 0.440" length), requiring verification of board layout constraints during implementation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-26J be used as a direct replacement for the Bourns 9220-26?

A: Yes. Both components share identical inductance (910 µH), tolerance (±5%), DC resistance (15.8Ω max), shielding configuration (unshielded), operating temperature range (-55°C to 105°C), and axial through-hole mounting. The substitute meets or exceeds all critical electrical specifications.

Q: What is the difference between drum core and molded core construction?

A: The Bourns 9220-26 uses drum core wirewound construction, while the API Delevan 2500-26J uses molded construction. Both achieve the same electrical performance at the specified inductance and current ratings. Core material differs (ferrite versus iron), but this does not affect functional equivalence for the stated application parameters.

Q: Will the larger physical dimensions of the 2500-26J cause compatibility issues?

A: The substitute is larger (0.240" diameter × 0.740" length versus 0.190" diameter × 0.440" length). Board layout and component spacing must be verified before implementation to ensure mechanical fit within the available footprint.

Q: Are there compliance or certification differences between these parts?

A: Both components are RoHS non-compliant and REACH unaffected. No compliance advantage exists between the original and substitute. The 2500-26J carries active product status with current manufacturing support, whereas the 9220-26 is obsolete.

Q: What is the current rating difference, and does it matter?

A: The 2500-26J is rated for 91 mA compared to the 9220-26 at 79 mA. The higher rating on the substitute provides additional design margin and does not create incompatibility when used in circuits designed for the lower original specification.
