Bourns 9210-80 Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9210-80 is a 120 µH unshielded molded inductor rated for 124 mA with a maximum DC resistance of 5.2 Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The 9210-80 operates across the temperature range of -55°C to 105°C and is suitable for applications requiring fixed inductance values in the 120 µH range with moderate current handling capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9210-80 is determined by the following critical parameters:

• Inductance Value: Must match 120 µH
• Inductance Tolerance: Must be ±5% or tighter
• DC Resistance: Must not exceed 5.2 Ohm maximum
• Current Rating: Must meet or exceed 124 mA minimum
• Mounting Type: Must be through-hole axial configuration
• Physical Dimensions: Must be compatible with 0.156" Dia x 0.375" L footprint
• Operating Temperature Range: Must support -55°C to 105°C
• Shielding Configuration: Unshielded topology

The API Delevan 1537-80J meets all substitution criteria. While the core material differs (iron versus ferrite), both materials achieve the specified electrical performance parameters. The 1537-80J provides a higher current rating of 140 mA, exceeding the minimum 124 mA requirement, and maintains identical inductance, tolerance, DC resistance, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-80J is a direct functional substitute for the obsolete Bourns 9210-80. Both components share identical electrical specifications for inductance, tolerance, DC resistance, quality factor, and self-resonant frequency. The 1537-80J maintains full compatibility with the original design footprint and thermal operating range.

The primary advantage of the 1537-80J is its active product status, ensuring long-term availability and supply chain continuity. The higher current rating of 140 mA provides additional design margin beyond the original 124 mA specification. Both components carry identical RoHS non-compliance and REACH unaffected certifications.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-80J be used as a direct replacement for the Bourns 9210-80?

A: Yes. The 1537-80J meets all electrical and mechanical substitution criteria, including inductance value, tolerance, DC resistance, current rating, operating temperature range, and physical dimensions. The components are pin-compatible for through-hole axial mounting.

Q: What is the difference in core material between these inductors?

A: The Bourns 9210-80 uses ferrite core material, while the API Delevan 1537-80J uses iron core material. Both materials achieve the specified electrical performance parameters of 120 µH inductance, 5.2 Ohm maximum DC resistance, and 65 Q factor at 790 kHz.

Q: Does the higher current rating of the 1537-80J affect circuit performance?

A: No. The 1537-80J's 140 mA current rating exceeds the original 124 mA requirement, providing additional design margin. All other electrical parameters remain identical, ensuring equivalent circuit behavior.

Q: Are there packaging differences between these parts?

A: The Bourns 9210-80 is supplied in standard packaging, while the API Delevan 1537-80J is available in Tape & Reel (TR) format. Both use identical axial through-hole package configuration with matching physical dimensions.

Q: What is the product status significance?

A: The Bourns 9210-80 is classified as obsolete, indicating discontinued production. The API Delevan 1537-80J maintains active product status, ensuring ongoing availability and supply chain support for new designs and production requirements.
