Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-103K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±10%
• Current rating: 6.44 A minimum
• Saturation current: 5.2 A minimum
• DC resistance: 16 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters:

• Mounting type: Through hole
• Package configuration: Axial
• Physical dimensions: 0.455" Dia x 0.900" L (11.55mm x 22.86mm)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C minimum

The 4590R-103K qualifies as a direct substitute because it maintains identical electrical specifications, core material, shielding, mounting configuration, package type, and physical dimensions as the primary part number 4590-103K.

Engineering Selection Recommendations

Primary Part: 4590-103K

The 4590-103K remains the original specification component with active production status and 869 pieces in current inventory. This part is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required.

Substitute Part: 4590R-103K

The 4590R-103K is a direct electrical and mechanical equivalent with identical inductance, current rating, DC resistance, core material, shielding, mounting type, package configuration, and physical dimensions. The primary distinction is RoHS3 compliance status. The 4590R-103K is suitable for applications requiring RoHS compliance and maintains higher inventory availability at 1753 pieces in new original condition.

Both components are manufactured by API Delevan Inc. within the 4590 series and are classified as active products. Selection between these two parts should be based on regulatory compliance requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-103K replace the 4590-103K in existing designs?

A: Yes. The 4590R-103K is electrically and mechanically equivalent to the 4590-103K. Both components have identical inductance values (10 µH), current ratings (6.44 A), DC resistance (16 mOhm max), core material (ferrite), shielding (unshielded), mounting type (through hole), package configuration (axial), and physical dimensions (0.455" Dia x 0.900" L). The components are pin-compatible and footprint-compatible for PCB applications.

Q: What is the difference between the 4590-103K and 4590R-103K?

A: The primary difference is RoHS compliance status. The 4590-103K is RoHS non-compliant, while the 4590R-103K is ROHS3 compliant. All electrical and mechanical specifications are identical between the two part numbers.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, the 4590R-103K is the appropriate choice. For applications where RoHS compliance is not required, either part may be used based on availability and cost considerations.

Q: Are there any performance differences between these inductors?

A: No. Both the 4590-103K and 4590R-103K have identical electrical performance characteristics, including inductance value, tolerance, current rating, saturation current, DC resistance, operating temperature range, and frequency response at 1 kHz test frequency.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. The 4590-103K and 4590R-103K are direct substitutes and can be used interchangeably in circuit applications. Both components maintain the same electrical specifications and physical form factor for through-hole axial mounting.

Q: What is the inventory status for these parts?

A: The 4590-103K has 869 pieces in new original stock. The 4590R-103K has 1753 pieces in new original stock, providing greater availability for supply chain planning.
