Bourns 5900-562 Equivalent & Substitute Parts

Part Overview

The Bourns 5900-562 is a 5.6 mH unshielded drum core wirewound inductor rated for 320 mA with a maximum DC resistance of 4.1 Ohm, designed for through-hole axial mounting. This component operates across the temperature range of -55°C to 105°C and is specified at 1 kHz inductance frequency testing. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-562 is determined by the following critical parameters:

• Inductance value: 5.6 mH with ±10% tolerance
• Core type and shielding configuration: Ferrite, unshielded drum core
• Mounting and package: Through-hole axial configuration
• Physical dimensions: Compatible with 0.453" diameter and 0.900" length envelope
• Current handling capability: Minimum 320 mA rating required
• DC resistance: Maximum 4.1 Ohm specification

The API Delevan 4590-565K meets these substitution criteria with matching inductance, core material, shielding type, mounting configuration, and compatible physical dimensions. The substitute part provides enhanced current rating (395 mA) and extended operating temperature range (-55°C to 125°C), supporting direct functional replacement in applications requiring the specified inductance and current characteristics.

Engineering Selection Recommendations

The API Delevan 4590-565K is the qualified substitute for the obsolete Bourns 5900-562. Selection is based on the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• Electrical parameters match the original specification: 5.6 mH inductance at ±10% tolerance, ferrite core, unshielded configuration
• Current rating of 395 mA exceeds the original 320 mA requirement, providing operational margin
• DC resistance of 4.24 Ohm remains within acceptable tolerance of the original 4.1 Ohm specification
• Physical dimensions are compatible with the original axial through-hole mounting envelope
• Extended operating temperature range (-55°C to 125°C) provides broader thermal operating capability compared to the original -55°C to 105°C range
• Both components share identical RoHS and REACH compliance status

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-565K directly replace the Bourns 5900-562 in existing designs?

A: Yes. The substitute part maintains the same inductance value, tolerance, core material, shielding configuration, and axial through-hole mounting. Physical dimensions are compatible within the component envelope. The higher current rating and extended temperature range provide additional operational capability.

Q: What is the impact of the 0.24 Ohm increase in DC resistance?

A: The DC resistance increases from 4.1 Ohm to 4.24 Ohm, representing a 5.9% increase. This remains within typical manufacturing tolerance ranges for wirewound inductors and does not constitute a functional limitation for applications designed to the original 4.1 Ohm specification.

Q: Are there any compliance differences between the two parts?

A: Both components share identical RoHS non-compliance and REACH unaffected status. No compliance advantage exists between the original and substitute part.

Q: Why is the Bourns 5900-562 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The API Delevan 4590-565K, with active product status, provides continuity for applications requiring 5.6 mH ferrite core wirewound inductors in axial through-hole configuration.

Q: Are the physical dimensions identical?

A: Dimensions are compatible. The Bourns part measures 0.453" diameter by 0.900" length, while the API Delevan part measures 0.455" diameter by 0.900" length. The 0.002" diameter difference is negligible for through-hole mounting applications and does not affect PCB layout or mechanical fit.
