Substitute Part Grouping Explanation

The 4590R-565K qualifies as a direct substitute for the 4590-565K based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical substitution criteria: inductance value of 5.6 mH at ±10% tolerance, current rating of 395 mA, saturation current of 240 mA, DC resistance of 4.24 Ohm maximum, ferrite core material, unshielded configuration, through-hole mounting, axial package, and identical physical dimensions of 0.455" diameter by 0.900" length. The operating temperature range of -55°C to 125°C and inductance test frequency of 1 kHz are maintained across both parts. The primary distinction between these components lies in their series designation (4590 versus 4590R) and compliance status, with the 4590R-565K offering RoHS3 compliance compared to the non-compliant status of the original 4590-565K.

Parameter Comparison

Engineering Selection Recommendations

The 4590R-565K serves as the direct equivalent substitute for the 4590-565K in applications where RoHS3 compliance is required or preferred. Both components maintain active production status and are manufactured by API Delevan Inc. Selection between these parts should be based on compliance requirements: the 4590-565K remains suitable for applications without RoHS3 mandates, while the 4590R-565K is specified for designs requiring RoHS3 compliance. Electrical performance, thermal characteristics, and mechanical compatibility are identical between both parts, ensuring seamless substitution at the circuit level. Current inventory availability shows 1223 pieces of the 4590R-565K and 1118 pieces of the 4590-565K in stock.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-565K replace the 4590-565K in existing designs? A: Yes. Both components are electrically and mechanically identical across all specified parameters including inductance, current rating, DC resistance, core material, dimensions, and operating temperature range. Direct substitution is supported at the circuit board level.

Q: What is the primary difference between these two part numbers? A: The 4590R-565K is RoHS3 compliant, while the 4590-565K is RoHS non-compliant. All other electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical? A: Yes. Both components share identical dimensions of 0.455" diameter by 0.900" length (11.55mm x 22.86mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: What is the saturation current specification? A: Both parts have a saturation current (Isat) of 240 mA, which is lower than the rated current of 395 mA. This parameter defines the point at which the inductor begins to saturate and inductance value degrades.

Q: Can these inductors be used in high-temperature applications? A: Both components are rated for operation across -55°C to 125°C, supporting extended temperature range applications within this specification window.

Q: What core material is used in these inductors? A: Both components utilize ferrite core material in an unshielded drum core configuration, suitable for general-purpose filtering and energy storage applications.
