Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-153 is determined by the following critical parameters:

• Inductance Value: Must match 15 mH at 1 kHz test frequency
• Inductance Tolerance: Must be ±10% or tighter
• Core Type: Must be ferrite drum core construction
• Shielding Configuration: Must be unshielded
• Mounting and Package: Must be through-hole axial configuration
• DC Resistance: Substitute must not exceed the maximum specified value to ensure circuit performance
• Current Rating: Substitute must support the required current without saturation within the operating envelope
• Operating Temperature: Substitute must cover or exceed the specified temperature range

The API Delevan 4590-156K meets these substitution criteria as a direct equivalent for the 5900-153.

Engineering Selection Recommendations

The API Delevan 4590-156K is a suitable substitute for the obsolete Bourns 5900-153 based on the following factors:

Electrical Compatibility: Both components share identical inductance values (15 mH) and tolerance specifications (±10%) at the standard test frequency of 1 kHz. The 4590-156K provides higher continuous current capacity (250 mA versus 190 mA) and lower DC resistance (10.7 Ohm versus 11.5 Ohm maximum), which are favorable characteristics for circuit performance.

Mechanical Compatibility: Physical dimensions are nearly identical, with axial through-hole mounting in both cases. The 4590-156K dimensions (0.455" Dia x 0.900" L) are within acceptable tolerance of the original component (0.453" Dia x 0.900" L), ensuring PCB layout compatibility.

Operational Considerations: The 4590-156K operates across an extended temperature range (-55°C to 125°C) compared to the 5900-153 (-55°C to 105°C), providing additional thermal margin. Both components are RoHS non-compliant and REACH unaffected, maintaining equivalent regulatory status.

Supply Status: The 4590-156K is classified as active product, ensuring ongoing availability and supply chain continuity compared to the obsolete 5900-153.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4590-156K be used as a direct replacement for the Bourns 5900-153?

A: Yes. Both components share the same inductance value (15 mH), tolerance (±10%), core material (ferrite), shielding configuration (unshielded), and mounting type (through-hole axial). Physical dimensions are compatible within standard manufacturing tolerances.

Q: What are the key differences between these two inductors?

A: The 4590-156K provides higher current capacity (250 mA versus 190 mA), lower DC resistance (10.7 Ohm versus 11.5 Ohm), and an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). The saturation current specification differs (150 mA for the 4590-156K versus 210 mA for the 5900-153).

Q: Are there any compliance or regulatory differences?

A: Both components share identical RoHS and REACH status. Neither component is RoHS compliant, and both are REACH unaffected. Regulatory classification remains equivalent.

Q: Will the 4590-156K fit in the same PCB footprint?

A: Yes. The axial package dimensions are nearly identical (0.455" Dia x 0.900" L for the 4590-156K versus 0.453" Dia x 0.900" L for the 5900-153), ensuring compatibility with existing through-hole PCB layouts.

Q: What should be considered when selecting between these components?

A: Selection should be based on circuit current requirements and thermal operating conditions. The 4590-156K is recommended for applications requiring higher current capacity or extended temperature operation. Both components are suitable for circuits designed around the 15 mH inductance specification at 1 kHz.
