Bourns 5900-183 Equivalent & Substitute Parts

Part Overview

The Bourns 5900-183 is an 18 mH unshielded drum core wirewound inductor rated for 170 mA with a maximum DC resistance of 14 Ohm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. Substitute parts must maintain the same inductance value, core type, shielding configuration, and mounting methodology while operating within compatible electrical and thermal parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-183 is determined by the following critical parameters:

• Inductance value must be 18 mH with ±10% tolerance
• Core type must be drum core wirewound with ferrite material
• Shielding configuration must be unshielded
• Mounting type must be through-hole axial
• Current rating must meet or exceed 170 mA
• DC resistance must not exceed 14 Ohm maximum
• Physical dimensions must be compatible with 0.453" diameter and 0.900" length envelope
• Operating temperature range must encompass the application requirements

The API Delevan 4590-186K satisfies these substitution criteria with equivalent inductance, core construction, and mounting configuration, while providing enhanced current handling capability and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 4590-186K is a direct functional substitute for the obsolete Bourns 5900-183. Both components share identical inductance specifications, core construction, and mounting configuration. The substitute part provides superior current handling at 210 mA versus 170 mA, accommodating higher load conditions. The DC resistance differential of 0.8 Ohm is within acceptable tolerance for equivalent circuit performance.

The API Delevan component maintains active product status, ensuring continued availability and supply chain reliability. Both parts carry identical RoHS non-compliance and REACH unaffected certifications. The extended operating temperature range of the substitute (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin for demanding applications.

Physical dimensions are compatible within standard PCB layout tolerances, with diameter variance of 0.002" and identical axial length.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-186K replace the Bourns 5900-183 in existing designs?

A: Yes. Both inductors share the same 18 mH inductance value, ±10% tolerance, ferrite drum core construction, unshielded configuration, and through-hole axial mounting. Physical dimensions are compatible within standard PCB tolerances.

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

A: The API Delevan 4590-186K is rated for 210 mA compared to the original 170 mA. This provides additional design margin and allows operation at higher current levels without saturation concerns. Applications limited to 170 mA or below will operate within safe parameters on either component.

Q: How does the DC resistance difference affect circuit performance?

A: The substitute part has a maximum DC resistance of 14.8 Ohm versus 14 Ohm on the original. This 0.8 Ohm difference represents approximately 5.7% variance and will produce proportionally minimal voltage drop changes in typical circuit applications.

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

A: Both components are RoHS non-compliant and REACH unaffected. Compliance status is identical between the original and substitute part.

Q: What is the physical compatibility consideration?

A: The substitute part diameter is 0.455" compared to 0.453" on the original, a difference of 0.002". Both maintain 0.900" axial length. This minimal dimensional variance is within standard PCB layout tolerances and does not affect through-hole mounting compatibility.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: The API Delevan 4590-186K operates from -55°C to 125°C versus -55°C to 105°C on the original. The substitute provides additional thermal operating margin and is fully compatible with applications designed for the original temperature range.
