5900-392-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5900-392-RC is a 3.9 mH unshielded drum core wirewound inductor rated for 370 mA continuous current with a maximum DC resistance of 3.1 Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is ROHS3 compliant. The part is currently active in production with 1947 units in stock. Substitute parts are identified when equivalent inductance values, similar current ratings, and compatible mechanical dimensions are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5900-392-RC are qualified based on the following criteria:

• Inductance value of 3.9 mH (matching the primary specification)
• Current rating within acceptable operating margins (minimum 370 mA)
• DC resistance comparable to or lower than 3.1 Ohm maximum
• Unshielded wirewound construction
• Through-hole axial mounting configuration
• Compatible physical dimensions (approximately 0.45" diameter × 0.90" length)
• ROHS3 compliance and REACH unaffected status
• Operating temperature range supporting -55°C minimum

The identified substitutes meet these electrical and mechanical parameters, enabling direct replacement in circuit designs without modification to PCB layouts or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All three inductors meet ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in applications requiring regulatory adherence. The 4590R-395K and AIAP-03-392K both offer higher current ratings (480 mA and 430 mA respectively) compared to the primary 5900-392-RC specification of 370 mA, providing additional thermal margin in current-limited applications. Both substitutes feature lower DC resistance values (2.84 Ohm and 2.75 Ohm), reducing power dissipation relative to the 3.1 Ohm maximum of the primary part. The extended operating temperature range of -55°C to 125°C for both substitutes accommodates applications requiring higher temperature performance beyond the 5900-392-RC upper limit of 105°C. Physical dimensions across all three parts remain within 0.006" tolerance, ensuring mechanical compatibility in standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-395K or AIAP-03-392K be used as direct replacements for the 5900-392-RC?

A: Yes. Both substitutes maintain the 3.9 mH inductance specification, unshielded wirewound construction, through-hole axial mounting, and equivalent physical dimensions. The higher current ratings and lower DC resistance of the substitutes provide equal or improved performance in the primary application.

Q: What is the significance of the current rating difference between the main part and substitutes?

A: The 5900-392-RC is rated for 370 mA continuous current. The 4590R-395K (480 mA) and AIAP-03-392K (430 mA) offer higher current capacity, allowing operation at higher current levels without exceeding thermal limits. In applications operating below 370 mA, all three parts are functionally equivalent.

Q: Are there temperature range considerations for substitution?

A: The 5900-392-RC operates from -55°C to 105°C. Both substitutes extend the upper limit to 125°C. For applications requiring operation above 105°C, the 4590R-395K or AIAP-03-392K are required. For applications within -55°C to 105°C, all three parts are suitable.

Q: How do DC resistance differences affect circuit performance?

A: The 5900-392-RC specifies 3.1 Ohm maximum DC resistance. The 4590R-395K (2.84 Ohm) and AIAP-03-392K (2.75 Ohm) feature lower resistance, resulting in reduced power dissipation and lower voltage drop across the inductor at equivalent current levels. This represents an improvement over the primary specification.

Q: Are all three parts available in the same packaging format?

A: The 5900-392-RC is supplied in Tray packaging, while the 4590R-395K and AIAP-03-392K are supplied in Bulk packaging. All three use identical through-hole axial package geometry, ensuring PCB compatibility. Packaging format does not affect electrical or mechanical substitution.

Q: What compliance certifications apply to all substitute parts?

A: All three inductors are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.
