Bourns 5900-4R7 Equivalent & Substitute Parts

Part Overview

The Bourns 5900-4R7 is a 4.7 µH unshielded drum core wirewound inductor rated for 5.7 A continuous current with 14 mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5900-4R7 carries obsolete product status. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for legacy system maintenance and new designs requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the 5900-4R7 are classified based on electrical and mechanical compatibility within the following criteria:

Direct Equivalent (5900-4R7-RC): Identical inductance (4.7 µH), tolerance (±10%), current rating (5.7 A), DC resistance (14 mOhm Max), saturation current (13 A), core material (ferrite), shielding (unshielded), mounting type (through hole), package (axial), and physical dimensions (0.453" Dia x 0.900" L). Differs only in packaging format (tray vs. bulk) and product status (active vs. obsolete).

Similar Substitute (4590-472K): Maintains identical inductance (4.7 µH), tolerance (±10%), core material (ferrite), shielding (unshielded), mounting type (through hole), package (axial), and physical dimensions (0.455" Dia x 0.900" L). Differs in current rating (9.11 A vs. 5.7 A), DC resistance (8 mOhm vs. 14 mOhm), saturation current (7.5 A vs. 13 A), and operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). Suitable for applications where higher current capacity and lower DC resistance are acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The 5900-4R7-RC is the primary substitute for the obsolete 5900-4R7. Both parts share identical electrical specifications and physical dimensions. The 5900-4R7-RC maintains active product status and achieves ROHS3 compliance, making it suitable for new designs and legacy system updates where regulatory compliance is required.

For Enhanced Performance Applications: The 4590-472K from API Delevan Inc. provides higher current capacity (9.11 A vs. 5.7 A) and lower DC resistance (8 mOhm vs. 14 mOhm). This substitute is applicable in designs where the original 5.7 A rating provides insufficient margin or where reduced resistive losses are beneficial. The extended operating temperature range (-55°C ~ 125°C) accommodates more demanding thermal environments. Physical dimensions remain compatible (0.455" Dia vs. 0.453" Dia, negligible difference). Note that the 4590-472K is RoHS non-compliant, consistent with the original part's compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 5900-4R7-RC be used as a direct drop-in replacement for the 5900-4R7?

A: Yes. The 5900-4R7-RC is electrically and mechanically identical to the 5900-4R7. Both parts feature 4.7 µH inductance, 5.7 A current rating, 14 mOhm DC resistance, and identical physical dimensions. The only differences are packaging format (tray vs. bulk) and product status (active vs. obsolete).

Q: What are the key differences between the 5900-4R7 and the 4590-472K?

A: Both parts maintain 4.7 µH inductance and ±10% tolerance. The 4590-472K provides higher current capacity (9.11 A vs. 5.7 A), lower DC resistance (8 mOhm vs. 14 mOhm), and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). Physical dimensions are nearly identical (0.455" Dia vs. 0.453" Dia). The 4590-472K is suitable for applications requiring higher current handling or lower resistive losses.

Q: Are there packaging considerations when selecting a substitute?

A: The 5900-4R7-RC is supplied in tray packaging, while the original 5900-4R7 and the 4590-472K are supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance but may influence procurement, handling, and storage procedures.

Q: Which substitute should be selected for new designs?

A: The 5900-4R7-RC is recommended for new designs requiring direct compatibility with the original 5900-4R7 specification. It offers the advantage of active product status and ROHS3 compliance. The 4590-472K is appropriate for designs where higher current capacity or lower DC resistance provides functional or performance benefits.

Q: Do the substitute parts maintain the same operating temperature range?

A: The 5900-4R7-RC maintains the original operating range of -55°C ~ 105°C. The 4590-472K extends this range to -55°C ~ 125°C, providing additional thermal margin for high-temperature applications.
