Bourns 5900-332 Equivalent & Substitute Parts

Part Overview

The Bourns 5900-332 is a 3.3 mH unshielded drum core wirewound inductor rated for 390 mA with a maximum DC resistance of 2.8 Ohm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5900-332 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and redesign efforts for legacy systems utilizing this inductor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5900-332 is determined by the following critical parameters:

• Inductance Value: Must match 3.3 mH at 1 kHz test frequency
• Inductance Tolerance: ±10% specification must be maintained
• Core Type and Shielding: Ferrite core, unshielded construction
• Mounting and Package: Through-hole axial configuration
• Current Handling: Current rating and saturation current must support the application's maximum operating current
• DC Resistance: Must remain within acceptable limits for the circuit design
• Operating Temperature: Must cover the required temperature range

The API Delevan 4590-335K meets these substitution criteria with matching inductance, tolerance, core material, shielding, mounting type, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 4590-335K is an active product suitable for substituting the obsolete Bourns 5900-332. Both components share identical inductance values, tolerance specifications, core materials, and mounting configurations. The 4590-335K provides an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and lower DC resistance (2.53 Ohm versus 2.8 Ohm maximum).

Circuit designers must verify that the saturation current specification of the 4590-335K (310 mA) is compatible with the application's maximum operating current. The 5900-332 specifies 460 mA saturation current, while the substitute provides 310 mA. Applications operating near or above 310 mA saturation current require evaluation against the original design specifications.

Both components are RoHS non-compliant and REACH unaffected. Compliance requirements for the target application must be assessed independently.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-335K directly replace the Bourns 5900-332 in all applications?

A: The 4590-335K matches the critical electrical and mechanical parameters (inductance, tolerance, core type, shielding, mounting, and package). However, the saturation current differs (310 mA versus 460 mA). Applications operating above 310 mA require verification that the substitute's saturation specification is acceptable for the circuit design.

Q: What are the physical compatibility considerations?

A: Both inductors use axial through-hole mounting with nearly identical dimensions (0.453" versus 0.455" diameter; both 0.900" length). Physical fit on printed circuit boards is compatible. Verify PCB hole spacing and lead bend radius accommodate the substitute component.

Q: Does the extended temperature range of the 4590-335K affect substitution suitability?

A: The 4590-335K operates to 125°C versus the 5900-332's 105°C maximum. This extended range does not prevent substitution; it provides additional operational margin for applications requiring higher temperature performance.

Q: Are there compliance differences between the two inductors?

A: Both components are RoHS non-compliant and REACH unaffected. Compliance status is identical. Applications with specific regulatory requirements must evaluate both components against those requirements independently.

Q: How does the lower DC resistance of the 4590-335K impact circuit performance?

A: The 4590-335K specifies 2.53 Ohm maximum DC resistance compared to 2.8 Ohm for the 5900-332. Lower resistance reduces power dissipation and heat generation. Circuit designs dependent on specific resistance values for impedance matching or filtering must be evaluated for compatibility with the lower resistance specification.
