Bourns 5900-151 150µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5900-151 is a 150µH unshielded drum core wirewound inductor rated for 2A continuous current with a maximum DC resistance of 110mOhm. 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 compact form factors.

The 5900-151 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5900-151 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for direct substitution:

• Inductance value: 150 µH
• Tolerance: ±10%
• Core type: Ferrite, unshielded drum core
• Mounting: Through hole, axial package
• Physical dimensions: Compatible with 0.453" diameter and 0.900" length envelope
• Inductance test frequency: 1 kHz

Current rating, DC resistance, saturation current, and operating temperature ranges may vary within acceptable limits for the application. Compliance status and product availability are secondary considerations that support substitution decisions.

Parameter Comparison

Engineering Selection Recommendations

5900-151-RC (Bourns Inc.) is the primary substitute for the obsolete 5900-151. This part maintains identical electrical specifications, physical dimensions, and operating temperature range. The 5900-151-RC is currently in active production status with ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs or production restarts. Packaging differs (tray versus original specification), but electrical and mechanical compatibility is complete.

4590-154K (API Delevan Inc.) serves as an alternative substitute when 5900-151-RC availability is constrained. This part matches the core inductance, tolerance, and mounting configuration. The 4590-154K offers a higher current rating (2.27A versus 2A) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). DC resistance is slightly elevated at 129mOhm maximum compared to 110mOhm, and saturation current is lower at 1.4A. Physical dimensions are nearly identical (0.455" diameter versus 0.453"). Selection of 4590-154K requires verification that the elevated DC resistance and lower saturation current do not impact circuit performance.

Frequently Asked Questions (FAQ)

Q: Can 5900-151-RC be used as a direct replacement for 5900-151?

A: Yes. The 5900-151-RC is electrically and mechanically identical to the 5900-151, with matching inductance (150µH), current rating (2A), DC resistance (110mOhm max), and physical dimensions. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Packaging format differs (tray versus unspecified), but this does not affect component function.

Q: What are the limitations of using 4590-154K as a substitute?

A: The 4590-154K maintains the same inductance value and tolerance but introduces two electrical differences: DC resistance increases from 110mOhm to 129mOhm maximum, and saturation current decreases from 2.1A to 1.4A. These parameters must be evaluated against circuit requirements. The 4590-154K offers advantages in current rating (2.27A) and operating temperature range (-55°C to 125°C). Physical dimensions are compatible within tolerance (0.455" diameter versus 0.453").

Q: Are there packaging considerations when substituting these parts?

A: The 5900-151 original packaging specification is not detailed in available data. The 5900-151-RC is supplied in tray packaging, while 4590-154K is supplied in bulk packaging. Verify that packaging format meets procurement, handling, and assembly requirements for your application.

Q: What compliance differences exist between these parts?

A: The 5900-151 and 4590-154K are both RoHS non-compliant. The 5900-151-RC is ROHS3 compliant. If regulatory compliance is required for your application, the 5900-151-RC is the appropriate selection.

Q: Can these parts be used interchangeably in legacy circuit designs?

A: The 5900-151-RC provides complete electrical and mechanical interchangeability with the original 5900-151. The 4590-154K requires circuit-level evaluation due to differences in DC resistance and saturation current. Consult circuit design documentation to confirm that these parameter variations are acceptable for your specific application.
