Engineering Selection Recommendations

The 4590R-224K serves as a direct electrical and mechanical equivalent to the 4590-224K. Both parts are manufactured by API Delevan Inc. and maintain identical specifications across all critical electrical parameters: 220 µH inductance at ±10% tolerance, 2.025 A current rating, 1.2 A saturation current, and 162 mOhm maximum DC resistance. Physical dimensions and through-hole axial mounting are identical, ensuring PCB compatibility without layout modification.

A key distinction exists in regulatory compliance: the 4590-224K is RoHS non-compliant, while the 4590R-224K is ROHS3 compliant. Selection between these parts depends on end-product regulatory requirements. Applications subject to RoHS3 directives must use the 4590R-224K. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations.

The 4590R-224K currently maintains higher inventory availability at 3525 pieces compared to 646 pieces for the 4590-224K, providing supply chain advantages for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-224K replace the 4590-224K in existing designs?

A: Yes, the 4590R-224K is electrically and mechanically equivalent to the 4590-224K. All electrical specifications, physical dimensions, and mounting characteristics are identical. Substitution requires no circuit design changes or PCB layout modifications.

Q: What is the primary difference between these two parts?

A: The primary difference is RoHS compliance status. The 4590-224K is RoHS non-compliant, while the 4590R-224K is ROHS3 compliant. Both parts are electrically and mechanically identical.

Q: Which part should be selected for RoHS-regulated applications?

A: The 4590R-224K must be used for applications subject to RoHS3 directives. The 4590-224K is not suitable for RoHS-regulated end products.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the 4590-224K and 4590R-224K measure 0.455" diameter by 0.900" length (11.55 mm × 22.86 mm). They are identical axial through-hole components with no dimensional differences.

Q: Is the current rating the same for both inductors?

A: Yes. Both parts are rated for 2.025 A continuous current with a saturation current of 1.2 A. DC resistance is 162 mOhm maximum for both parts.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, provided regulatory compliance requirements are satisfied. If RoHS compliance is not required, either part may be used. If RoHS3 compliance is required, only the 4590R-224K is acceptable.
