Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bourns 9210-56 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the original specification:

• Inductance value: 39 µH (±5% tolerance)
• DC resistance: 2.6 Ohm maximum
• Current rating: minimum 176 mA
• Q factor: 60 @ 2.5 MHz
• Self resonant frequency: 14.5 MHz
• Operating temperature range: -55°C to 105°C
• Mounting type: Through hole
• Package: Axial
• Physical dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)
• Shielding: Unshielded

The API Delevan 1537-56J meets these criteria with an enhanced current rating of 198 mA, providing additional design margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-56J is a direct functional equivalent to the Bourns 9210-56. Both components share identical inductance, tolerance, DC resistance, Q factor, self resonant frequency, and operating temperature specifications. The substitute part offers a higher current rating of 198 mA compared to the original 176 mA specification, providing additional design margin without compromising any electrical characteristics.

The API Delevan 1537-56J is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts carry identical RoHS non-compliant, REACH unaffected, and EAR99 ECCN classifications. The substitute is available in Tape & Reel packaging, which may require process adjustment if the original design utilized bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-56J directly replace the Bourns 9210-56 in existing designs?

A: Yes. The 1537-56J meets all electrical specifications of the 9210-56, including inductance, tolerance, DC resistance, Q factor, and frequency characteristics. Physical dimensions and mounting type are identical, enabling direct board-level substitution.

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

A: The API Delevan 1537-56J is rated for 198 mA compared to the original 176 mA. This higher rating provides additional design margin and does not negatively impact circuit performance. The part remains suitable for applications designed for the original 176 mA specification.

Q: Are there packaging differences between these parts?

A: The Bourns 9210-56 is supplied in bulk packaging, while the API Delevan 1537-56J is available in Tape & Reel (TR) format. This may require adjustment to receiving, handling, and assembly processes but does not affect electrical or mechanical compatibility.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the Bourns 9210-56 and API Delevan 1537-56J carry identical RoHS non-compliant status, REACH unaffected classification, and EAR99 ECCN designation.

Q: Why is the Bourns 9210-56 listed as obsolete?

A: The Bourns 9210-56 has been discontinued by the manufacturer. The API Delevan 1537-56J is an active production equivalent that provides functional continuity for designs currently using or specifying the obsolete Bourns part.
