Equivalent & Substitute Parts for Bourns 5900-560 56µH Wirewound Inductor

Part Overview

The Bourns 5900-560 is a 56µH unshielded drum core wirewound inductor rated for 2.9A continuous current with 50mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance filtering and energy storage in power conversion circuits.

The 5900-560 is classified as obsolete. Equivalent substitute parts are available from active product lines that maintain the same 56µH inductance value, ±10% tolerance, unshielded configuration, and through-hole axial mounting while offering improved current ratings and lower DC resistance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-560 is determined by strict adherence to the following parameters:

Primary Matching Criteria (Non-Negotiable):

• Inductance value: 56µH
• Inductance tolerance: ±10%
• Mounting type: Through Hole
• Package configuration: Axial
• Shielding: Unshielded
• Test frequency: 1 kHz

Secondary Compatibility Criteria:

• Current rating must equal or exceed 2.9A
• DC resistance must not exceed 50mOhm maximum
• Operating temperature range must encompass or extend the -55°C to 105°C specification
• Core material and construction type must support equivalent inductance stability

The following parts meet all substitution criteria for the 5900-560:

1. API Delevan 4590-563K — Active product status, improved current rating (3.93A), lower DCR (43mOhm), extended temperature range (-55°C to 125°C)
2. API Delevan 4590R-563K — Active product status, improved current rating (3.93A), lower DCR (43mOhm), extended temperature range (-55°C to 125°C), RoHS3 compliant
3. Abracon AIAP-03-560K — Active product status, improved current rating (3.66A), lower DCR (37mOhm), extended temperature range (-55°C to 125°C), RoHS3 compliant

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The API Delevan 4590R-563K and Abracon AIAP-03-560K are preferred substitutes. Both are active products with RoHS3 compliance, supporting modern regulatory requirements. The 4590R-563K provides established API Delevan manufacturing continuity, while the AIAP-03-560K offers the lowest DC resistance (37mOhm) for reduced power dissipation.

For Existing Designs Requiring Obsolete Part Replacement: The API Delevan 4590-563K provides direct functional equivalence with active product status and improved electrical performance. Physical dimensions remain compatible with existing PCB layouts (0.455" diameter vs. 0.453" original, 0.900" length maintained).

For Compliance-Driven Applications: Select either the API Delevan 4590R-563K or Abracon AIAP-03-560K to meet RoHS3 requirements. Both maintain full electrical and mechanical compatibility while extending operating temperature range to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-563K directly replace the Bourns 5900-560 in existing assemblies?

A: Yes. Both parts maintain 56µH inductance at ±10% tolerance, identical through-hole axial mounting, and compatible physical dimensions (0.455" vs. 0.453" diameter, 0.900" length). The 4590-563K provides superior current rating (3.93A vs. 2.9A) and lower DC resistance (43mOhm vs. 50mOhm), making it functionally superior for the same application.

Q: What is the difference between API Delevan 4590-563K and 4590R-563K?

A: Both parts are electrically and mechanically identical with 56µH inductance, 3.93A current rating, and 43mOhm DC resistance. The primary difference is RoHS compliance: the 4590-563K is non-compliant, while the 4590R-563K is RoHS3 compliant. For new designs and regulated applications, the 4590R-563K is specified.

Q: Does the Abracon AIAP-03-560K offer advantages over the API Delevan alternatives?

A: The AIAP-03-560K provides the lowest DC resistance (37mOhm) among all substitutes, resulting in reduced power dissipation and improved thermal performance. It is RoHS3 compliant and maintains the same 56µH inductance and 3.66A current rating. Physical dimensions are nearly identical (0.449" diameter vs. 0.453" original).

Q: Are all substitute parts rated for the same temperature range as the original 5900-560?

A: No. The original 5900-560 operates from -55°C to 105°C. All three substitute parts extend the upper limit to 125°C, providing broader environmental operating capability. The lower temperature limit remains -55°C across all parts.

Q: Can these inductors be used interchangeably in high-frequency applications?

A: All parts are specified at 1 kHz test frequency. For applications requiring operation at significantly higher frequencies, self-resonant frequency and Q factor data must be obtained from the manufacturer, as these parameters are not provided in the standard datasheets.

Q: What is the inventory status for these substitute parts?

A: API Delevan 4590-563K: 742 units in stock. API Delevan 4590R-563K: 1202 units in stock. Abracon AIAP-03-560K: 680 units in stock. All are available as new original components.
