Bourns 9210-64 Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9210-64 is a 56 µH unshielded molded inductor rated for 164 mA with a maximum DC resistance of 3Ohm, 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 series inductors are commonly used in filtering, tuning, and energy storage applications where compact form factors and moderate current handling are required.

Substitute Part Grouping Explanation

The API Delevan 1537-64J qualifies as a functional substitute for the Bourns 9210-64 based on the following critical parameters:

  • Inductance Value: Both parts specify 56 µH with ±5% tolerance
  • DC Resistance: Both maintain 3Ohm maximum
  • Q Factor: Both measure 55 @ 2.5 MHz
  • Self Resonant Frequency: Both rated at 12 MHz
  • Operating Temperature: Both support -55°C to 105°C range
  • Physical Form Factor: Both are unshielded, through-hole axial inductors with identical dimensions (0.156" Dia × 0.375" L)
  • Inductance Test Frequency: Both tested at 2.5 MHz

The primary difference is the current rating, where the 1537-64J provides 184 mA versus the 9210-64's 164 mA, representing a 12% increase in current capacity. This higher rating does not preclude substitution in applications designed for the original 164 mA specification.

Engineering Selection Recommendations

The API Delevan 1537-64J is a direct functional substitute for the obsolete Bourns 9210-64. Both components share identical electrical specifications for inductance, tolerance, DC resistance, Q factor, and self-resonant frequency. The 1537-64J maintains the same physical footprint and through-hole axial mounting configuration, ensuring mechanical compatibility in existing PCB layouts.

The 1537-64J's active product status provides supply chain continuity and long-term availability, addressing the primary limitation of the obsolete 9210-64. Both parts carry identical RoHS non-compliance and REACH unaffected certifications, maintaining regulatory consistency in applications where these designations apply.

The increased current rating of the 1537-64J (184 mA versus 164 mA) does not introduce compatibility issues for designs specified to the original 164 mA rating, as the substitute operates within a higher performance envelope.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-64J directly replace the Bourns 9210-64 in existing designs?

A: Yes. Both inductors share identical inductance values (56 µH ±5%), DC resistance (3Ohm max), Q factors (55 @ 2.5 MHz), self-resonant frequencies (12 MHz), operating temperature ranges (-55°C to 105°C), and physical dimensions (0.156" Dia × 0.375" L). The through-hole axial mounting configuration is identical, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the current rating difference?

A: The 1537-64J is rated for 184 mA compared to the 9210-64's 164 mA. This 12% increase in current capacity means the substitute can handle higher current loads without saturation. For applications designed to the original 164 mA specification, the higher rating of the substitute provides additional thermal and operational margin.

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

A: Both parts share identical RoHS non-compliance and REACH unaffected designations. No compliance advantage exists between the two components. Applications requiring RoHS-compliant inductors must source alternative part families.

Q: Does packaging format affect substitution?

A: The Bourns 9210-64 is supplied in standard packaging, while the API Delevan 1537-64J is available in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel packaging is standard for automated assembly operations.

Q: What core material difference exists between these inductors?

A: The Bourns 9210-64 uses a ferrite core, while the API Delevan 1537-64J uses an iron core. Despite this material difference, both achieve identical electrical performance specifications at the test frequency of 2.5 MHz, including Q factor and self-resonant frequency.
