Bourns 9210-68 Equivalent & Substitute Parts

Part Overview

The Bourns 9210-68 is a 68 µH unshielded molded inductor rated for 156 mA with a maximum DC resistance of 3.3 Ohm, designed for through-hole axial mounting. This component operates across a temperature range of -55°C to 105°C and is characterized as obsolete. Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9210-68 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 68 µH with ±5% tolerance
• Current Rating: Minimum 156 mA (substitute may exceed this value)
• DC Resistance: 3.3 Ohm maximum
• Q Factor: 55 @ 2.5 MHz
• Self Resonant Frequency: 11 MHz
• Operating Temperature: -55°C to 105°C
• Shielding Configuration: Unshielded
• Mounting Type: Through-hole axial
• Physical Dimensions: 0.156" Dia x 0.375" L (3.96mm x 9.53mm)

The API Delevan 1537-68J meets all substitution criteria. While it features an iron core material (versus ferrite in the original) and a higher current rating of 176 mA, these differences remain within acceptable substitution parameters for this product category. The substitute maintains identical inductance, tolerance, DC resistance, Q factor, self resonant frequency, temperature range, shielding, mounting type, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-68J is a direct substitute for the obsolete Bourns 9210-68. The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity. Both components share identical RoHS non-compliance status, eliminating regulatory divergence in substitution. The higher current rating of the substitute (176 mA versus 156 mA) provides additional design margin without compromising electrical performance. Core material difference (iron versus ferrite) does not affect the specified electrical parameters that define functional equivalence in this application category.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-68J be used as a direct replacement for the Bourns 9210-68?

A: Yes. Both components share identical inductance (68 µH), tolerance (±5%), DC resistance (3.3 Ohm max), Q factor (55 @ 2.5 MHz), self resonant frequency (11 MHz), operating temperature range (-55°C to 105°C), shielding configuration (unshielded), and physical dimensions (0.156" Dia x 0.375" L). The substitute's higher current rating (176 mA) exceeds the original specification (156 mA), providing additional design margin.

Q: What is the significance of the core material difference between ferrite and iron?

A: While the Bourns 9210-68 uses ferrite core material and the API Delevan 1537-68J uses iron core material, both achieve identical electrical specifications for inductance, Q factor, and self resonant frequency as provided. Core material selection is a manufacturing implementation detail that does not alter the functional equivalence when all specified electrical parameters match.

Q: Why is the Bourns 9210-68 marked as obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by Bourns Inc. The API Delevan 1537-68J, with active product status, provides continuity for designs requiring 68 µH unshielded molded inductors with the specified electrical and mechanical characteristics.

Q: Are there packaging differences between these components?

A: The Bourns 9210-68 is supplied in standard packaging, while the API Delevan 1537-68J is available in Tape & Reel (TR) format. Both maintain identical through-hole axial package configuration and physical dimensions, ensuring mechanical compatibility in PCB assembly.

Q: Do both components meet the same compliance standards?

A: Both components share identical RoHS non-compliance status, REACH unaffected classification, and EAR99 ECCN designation. No compliance divergence exists between the original and substitute part.
