Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-685K is determined by strict alignment with critical electrical and mechanical parameters. The substitute part must match the following specifications: inductance value of 6.8 mH at ±10% tolerance, current rating of 340 mA minimum, DC resistance not exceeding 5.75Ohm, ferrite drum core construction, unshielded configuration, wirewound type, through-hole axial mounting, identical physical dimensions (0.455" Dia x 0.900" L), and operating temperature range of -55°C to 125°C. All substitute parts listed below satisfy these electrical and mechanical requirements, ensuring functional interchangeability within the specified design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the 4590-685K and 4590R-685K maintain identical electrical and mechanical specifications, ensuring complete functional interchangeability. The primary differentiation between these parts concerns regulatory compliance status. The 4590R-685K is ROHS3 compliant, while the original 4590-685K is RoHS non-compliant. Selection between these parts should be based on specific regulatory requirements within the target application and end market. Where RoHS3 compliance is mandatory for the final product assembly, the 4590R-685K becomes the required choice. Both parts maintain active production status with API Delevan Inc., ensuring ongoing availability and supply chain stability.

Frequently Asked Questions (FAQ)

What are the critical parameters for substituting the 4590-685K? Substitution requires exact matching of inductance (6.8 mH), current rating (340 mA), DC resistance (5.75Ohm maximum), core material (ferrite), shielding type (unshielded), mounting configuration (through-hole axial), physical dimensions (0.455" Dia x 0.900" L), and operating temperature range (-55°C to 125°C).

How does the 4590R-685K differ from the 4590-685K? Both parts are electrically and mechanically identical. The distinguishing factor is regulatory compliance: the 4590R-685K is ROHS3 compliant, whereas the 4590-685K is RoHS non-compliant. Selection depends on regulatory requirements for your application.

Can the 4590R-685K be used as a direct replacement for the 4590-685K? Yes, the 4590R-685K functions as a complete electrical and mechanical equivalent. Implementation is appropriate when RoHS3 compliance is required or when superior compliance status is preferred within the supply chain strategy.

What inventory levels are available? The 4590-685K maintains 859 pieces of new original stock, while the 4590R-685K holds 1,537 pieces of new original stock, providing greater availability for the RoHS-compliant variant.

Are there any physical mounting differences between these parts? Both parts share identical physical dimensions and through-hole axial mounting characteristics. No PCB layout or mechanical mounting modifications are required when transitioning between these parts.
