Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bourns 9210-58 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the original specification:

• Inductance value: 43 µH with ±5% tolerance
• DC Resistance: 2.7Ohm maximum
• Current Rating: minimum 172 mA (higher ratings are acceptable)
• Q Factor: 60 @ 2.5MHz
• Self Resonant Frequency: 13.7MHz
• Operating Temperature Range: -55°C ~ 105°C
• Mounting Type: Through Hole
• Package / Case: Axial
• Physical Dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Shielding: Unshielded
• Type: Molded

The API Delevan 1537-58J meets these criteria with an increased current rating of 194 mA, providing enhanced performance margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-58J is a direct functional equivalent to the Bourns 9210-58. Both components share identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. The substitute part provides a higher current rating of 194 mA compared to the original 172 mA specification, offering improved performance margin without compromising any other parameters.

Both parts maintain the same operating temperature range, physical dimensions, and axial through-hole mounting configuration, ensuring mechanical and thermal compatibility in existing circuit designs. The API Delevan 1537-58J is currently in active production status, providing supply chain continuity for the obsolete Bourns 9210-58.

Both components carry identical RoHS non-compliance and REACH unaffected certifications. Selection between these parts should be based on availability, lead time, and procurement requirements, as electrical performance is equivalent.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-58J directly replace the Bourns 9210-58 in existing designs?

A: Yes. The 1537-58J matches all critical electrical parameters including inductance value, tolerance, DC resistance, Q factor, and self-resonant frequency. Physical dimensions and mounting configuration are identical, enabling direct substitution in through-hole axial applications.

Q: What is the significance of the higher current rating on the substitute part?

A: The API Delevan 1537-58J is rated for 194 mA compared to the original 172 mA. This higher rating provides additional performance margin and does not negatively impact circuit operation. The part remains suitable for applications designed for the original 172 mA specification.

Q: Are there packaging differences between these parts?

A: The Bourns 9210-58 is supplied in standard packaging, while the API Delevan 1537-58J is available in Tape & Reel (TR) format. Both maintain identical component dimensions and axial configuration. Packaging format selection depends on assembly process requirements and order quantities.

Q: Do both parts have the same compliance certifications?

A: Both the Bourns 9210-58 and API Delevan 1537-58J are RoHS non-compliant and REACH unaffected. Compliance status is identical between the two parts.

Q: Why is the Bourns 9210-58 listed as obsolete?

A: The Bourns 9210-58 has been discontinued by the manufacturer. The API Delevan 1537-58J provides an active, in-production alternative with equivalent electrical and mechanical specifications for continued design support and procurement.
