Bourns 9220-20 680µH Axial Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9220-20 is a 680 µH unshielded drum core wirewound inductor rated for 85 mA continuous current with 13.7Ω maximum DC resistance. Designed for through-hole axial mounting, this component operates across the industrial temperature range of -55°C to 105°C. The part is currently obsolete, making identification of functionally equivalent substitutes essential for ongoing system support, repair, and redesign applications where this inductor specification remains required.

Substitute Part Grouping Explanation

Substitution of the Bourns 9220-20 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 680 µH (exact match required)
• Inductance Tolerance: ±5% (matching specification)
• DC Resistance: 13.7Ω maximum (electrical performance equivalence)
• Current Rating: Minimum 85 mA (functional capacity requirement)
• Operating Temperature Range: -55°C to 105°C (environmental compatibility)
• Mounting Configuration: Through-hole axial package (mechanical fit)
• Shielding Classification: Unshielded (EMI/RFI characteristics)

The API Delevan 2500-20J meets all substitution criteria. While core material differs (iron vs. ferrite) and physical dimensions vary, these differences do not affect functional equivalence when the above parameters are satisfied. The substitute part demonstrates superior current rating (97 mA vs. 85 mA) and maintains identical DC resistance and inductance specifications.

Engineering Selection Recommendations

The API Delevan 2500-20J (part number 2500-20J) is the qualified substitute for the obsolete Bourns 9220-20. Selection is based on the following factors:

Product Status: The Bourns 9220-20 is obsolete with no ongoing manufacturing. The API Delevan 2500-20J maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical Equivalence: Both components deliver identical inductance (680 µH ±5%), DC resistance (13.7Ω maximum), and operating temperature range (-55°C to 105°C). The substitute's higher current rating (97 mA vs. 85 mA) provides additional design margin without compromising performance.

Compliance Status: Both parts carry identical RoHS non-compliance and REACH unaffected designations. No compliance advantage exists between the two components.

Physical Compatibility: Both components use through-hole axial mounting with identical package classification. Physical dimensions differ (0.240" Dia × 0.740" L for substitute vs. 0.190" Dia × 0.440" L for original), requiring verification of PCB layout constraints in space-restricted applications.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-20J be used as a direct replacement for the Bourns 9220-20?

A: Yes. Both components meet identical electrical specifications for inductance, tolerance, DC resistance, current rating, and operating temperature. Through-hole axial mounting is identical. Physical dimensions differ; verify PCB layout accommodates the larger substitute package (0.240" Dia × 0.740" L).

Q: What is the primary reason for substitution?

A: The Bourns 9220-20 is obsolete. The API Delevan 2500-20J is an active production equivalent that maintains all critical electrical parameters while offering improved current capacity (97 mA vs. 85 mA).

Q: Are there any performance differences between the two inductors?

A: Core material differs (ferrite in the original vs. iron in the substitute). Both maintain identical inductance, DC resistance, and self-resonant frequency (3.4 MHz). The substitute demonstrates superior current handling capability.

Q: What packaging formats are available for the substitute part?

A: The API Delevan 2500-20J is supplied in Tape & Reel (TR) packaging. Verify packaging compatibility with assembly processes.

Q: Do both parts have identical RoHS and REACH compliance status?

A: Yes. Both the Bourns 9220-20 and API Delevan 2500-20J are RoHS non-compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.

Q: What should be verified before implementing the substitute in production?

A: Confirm PCB layout accommodates the larger physical dimensions of the substitute (0.240" Dia × 0.740" L). Verify packaging format (Tape & Reel) compatibility with assembly equipment. Validate thermal and electrical performance in the target application circuit.
