Bourns 5900-150 Equivalent & Substitute Parts

Part Overview

The Bourns 5900-150 is a 15 µH unshielded drum core wirewound inductor rated for 4.2 A continuous current with a maximum DC resistance of 25 mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance values in standard axial packages.

The 5900-150 carries an obsolete product status, making equivalent substitute parts necessary for ongoing design support and procurement. The API Delevan 4590-153K provides a direct functional alternative with improved electrical performance characteristics while maintaining mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-150 is determined by the following critical parameters:

• Inductance Value: Must match 15 µH with ±10% tolerance
• Core Type: Must be ferrite drum core wirewound construction
• Shielding Configuration: Must be unshielded
• Mounting Interface: Must be through-hole axial
• Package Dimensions: Physical size must be compatible with 0.453" diameter and 0.900" length specifications
• Current Handling: Substitute must support minimum 4.2 A continuous current rating
• DC Resistance: Substitute DCR must not exceed application requirements

The API Delevan 4590-153K satisfies all substitution criteria. Both components share identical inductance values, core materials, shielding characteristics, and mounting configurations. Physical dimensions are equivalent within manufacturing tolerances (0.455" Dia x 0.900" L). The substitute provides enhanced current capacity (5.76 A versus 4.2 A) and lower DC resistance (20 mOhm versus 25 mOhm), making it suitable for direct replacement in existing designs.

Engineering Selection Recommendations

The API Delevan 4590-153K is the qualified substitute for the obsolete Bourns 5900-150. Selection should be based on the following factors:

Product Status: The Bourns 5900-150 is obsolete, while the API Delevan 4590-153K maintains active product status with confirmed inventory availability (758 pcs in stock). Active status ensures continued supply chain access and manufacturing support.

Compliance Alignment: Both components share identical RoHS non-compliance status and REACH unaffected classification, maintaining regulatory consistency in existing designs.

Electrical Performance: The substitute provides superior electrical characteristics with 37% higher current capacity (5.76 A versus 4.2 A) and 20% lower DC resistance (20 mOhm versus 25 mOhm). These improvements reduce thermal dissipation and expand operational headroom in current-limited applications.

Thermal Operating Range: The API Delevan component extends the upper temperature limit to 125°C compared to 105°C for the original part, providing enhanced thermal margin in high-temperature environments.

Mechanical Compatibility: Physical dimensions are equivalent within standard manufacturing tolerances, ensuring direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-153K be used as a direct replacement for the Bourns 5900-150?

A: Yes. Both components share identical inductance values (15 µH ±10%), core materials (ferrite), shielding configurations (unshielded), and mounting interfaces (through-hole axial). Physical dimensions are equivalent within manufacturing tolerances. The substitute provides improved electrical performance with higher current capacity and lower DC resistance.

Q: What are the key differences between these two inductors?

A: The primary differences are product status (obsolete versus active), current rating (4.2 A versus 5.76 A), DC resistance (25 mOhm versus 20 mOhm), and maximum operating temperature (105°C versus 125°C). The substitute offers superior electrical characteristics and extended thermal range.

Q: Are there any compliance or certification differences?

A: Both components share identical RoHS non-compliance status and REACH unaffected classification. No compliance differences exist between the two parts.

Q: Will the substitute fit in existing PCB layouts designed for the Bourns 5900-150?

A: Yes. The axial package dimensions are equivalent (0.453" versus 0.455" diameter, both 0.900" length). These dimensional differences fall within standard manufacturing tolerances and do not require layout modifications.

Q: What is the inductance tolerance for both parts?

A: Both the Bourns 5900-150 and API Delevan 4590-153K maintain ±10% inductance tolerance, measured at 1 kHz.
