Substitute Part Grouping Explanation

Substitution between the 4590-107K and 4590R-107K is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical performance parameters: 100 mH inductance at ±10% tolerance, 90 mA current rating, 60 mA saturation current, 76 Ohm maximum DC resistance, ferrite drum core construction, unshielded configuration, through-hole axial mounting, and identical physical dimensions of 0.455" diameter by 0.900" length.

The substitution logic is determined by the following key parameters:

• Inductance value and tolerance band
• Current rating and saturation current specifications
• DC resistance maximum value
• Core material and construction type
• Shielding configuration
• Operating temperature range
• Physical package dimensions and mounting interface
• Axial lead configuration

Both parts maintain functional equivalence across all electrical and mechanical interfaces, enabling direct substitution in circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the 4590-107K and 4590R-107K are active production components from API Delevan Inc. with complete electrical and mechanical parameter equivalence. Selection between these parts should be based on regulatory compliance requirements specific to the end application.

The 4590-107K carries RoHS non-compliant status, making it suitable for applications where RoHS compliance is not mandated or where legacy component specifications are required.

The 4590R-107K is ROHS3 compliant, making it the appropriate selection for applications subject to RoHS Directive 2011/65/EU or equivalent regional regulations. Both components maintain identical REACH unaffected status and EAR99 export classification.

For new designs or applications requiring regulatory compliance documentation, the 4590R-107K is the preferred selection. For existing designs or applications without RoHS requirements, either component provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-107K directly replace the 4590-107K in existing circuit designs?

A: Yes. Both components share identical electrical specifications (100 mH inductance, 90 mA current rating, 76 Ohm DC resistance) and mechanical dimensions (0.455" diameter × 0.900" length axial package). Direct substitution is supported without circuit redesign or PCB layout modification.

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

A: The primary difference is regulatory compliance status. The 4590R-107K is ROHS3 compliant, while the 4590-107K is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both components feature identical axial package dimensions of 0.455" diameter by 0.900" length. Through-hole mounting interfaces are identical, supporting direct PCB footprint compatibility.

Q: What is the saturation current specification, and how does it relate to the 90 mA current rating?

A: The saturation current (Isat) is specified at 60 mA for both components. This represents the current level at which the inductor begins to exhibit nonlinear behavior due to core saturation. The 90 mA current rating is the maximum continuous current specification. Operating above saturation current results in reduced inductance and increased core losses.

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

A: The 4590R-107K is ROHS3 compliant and is the appropriate selection for applications subject to RoHS Directive 2011/65/EU or equivalent regional regulations requiring RoHS compliance documentation.

Q: Are both components available in the same packaging format?

A: Yes. Both the 4590-107K and 4590R-107K are supplied in bulk packaging as through-hole axial components with identical physical dimensions and lead configurations.

Q: What is the DC resistance specification, and why is it important?

A: The maximum DC resistance (DCR) is specified at 76 Ohm for both components. DC resistance represents the resistive losses in the inductor windings and affects power dissipation and circuit efficiency. This specification is identical across both parts.

Q: Can these inductors be used in high-frequency applications?

A: The inductance value is specified at 1 kHz test frequency. Self-resonant frequency data is not provided in the component specifications. Frequency-dependent performance characteristics should be verified through manufacturer datasheets for specific high-frequency applications.
