Substitute Part Grouping Explanation

The 4590R-563K from API Delevan Inc. qualifies as a substitute for the 5900-560-RC based on the following alignment of critical parameters:

• Inductance Match: Both parts specify 56 µH with ±10% tolerance at 1 kHz test frequency
• Core Configuration: Both utilize ferrite drum core construction with wirewound topology
• Shielding: Both are unshielded designs
• Mounting & Package: Both are through-hole axial components with equivalent physical dimensions (0.453" to 0.455" diameter, 0.900" length)
• Compliance: Both are ROHS3 compliant and REACH unaffected

Variations exist in current handling characteristics and operating temperature range. The 4590R-563K provides higher continuous current rating (3.93 A versus 2.9 A) and extended maximum operating temperature (125°C versus 105°C), while the 5900-560-RC offers lower DC resistance (50 mOhm versus 43 mOhm). These differences require application-specific evaluation based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 5900-560-RC and 4590R-563K are active production components with ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory adherence. Selection between these parts depends on circuit operating conditions:

• Select 5900-560-RC when the application operates within the -55°C to 105°C range and the 2.9 A current rating is sufficient for the circuit design
• Select 4590R-563K when higher current capacity (3.93 A) is required or when operation extends to 125°C maximum temperature is necessary

Physical dimensions are equivalent, ensuring PCB layout compatibility. Both parts are available in production quantities, with 1207 units of 5900-560-RC and 1202 units of 4590R-563K currently in stock.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-563K directly replace the 5900-560-RC in an existing circuit?

A: Direct replacement is possible when the circuit operates within the overlapping temperature range (-55°C to 105°C) and the 2.9 A minimum current rating of the 5900-560-RC is not exceeded by the 4590R-563K's 3.93 A rating. The equivalent inductance and core material ensure functional compatibility. Physical dimensions are compatible with standard through-hole PCB layouts.

Q: What is the significance of the different DC resistance values?

A: The 5900-560-RC specifies 50 mOhm maximum DCR, while the 4590R-563K specifies 43 mOhm maximum. Lower DC resistance reduces resistive losses in the inductor. Applications sensitive to power dissipation or thermal performance should account for this 7 mOhm difference when calculating circuit efficiency.

Q: Why do the saturation current ratings differ between these parts?

A: The 5900-560-RC has an Isat of 4.6 A, while the 4590R-563K has an Isat of 2.3 A. Saturation current indicates the point at which core material reaches magnetic saturation and inductance begins to degrade. Circuit designs must ensure operating current remains below the saturation point of the selected component.

Q: Are both parts suitable for high-temperature applications?

A: The 5900-560-RC operates to 105°C maximum, while the 4590R-563K extends to 125°C. For applications requiring sustained operation above 105°C, the 4590R-563K is the appropriate selection.

Q: Do packaging differences affect circuit board assembly?

A: The 5900-560-RC is supplied in trays, while the 4590R-563K is supplied in bulk packaging. Both are through-hole axial components with equivalent physical dimensions (approximately 11.5 mm diameter × 22.86 mm length), ensuring compatibility with standard PCB footprints and assembly processes.
