API Delevan 4590-475K Equivalent & Substitute Parts

Part Overview

The API Delevan 4590-475K is a fixed wirewound inductor featuring a 4.7 mH inductance value with a ferrite drum core design. This through-hole axial component is rated for 415 mA continuous current with a maximum DC resistance of 3.79 Ohm and operates across the temperature range of -55°C to 125°C. The component is currently active in production. Identifying equivalent and substitute parts becomes necessary when the primary part number is unavailable, when compliance requirements change, or when design revisions require alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-475K is determined by strict equivalence across the following critical parameters: inductance value (4.7 mH), inductance tolerance (±10%), current rating (415 mA), saturation current (260 mA), DC resistance (3.79 Ohm maximum), core material (ferrite), shielding configuration (unshielded), mounting type (through hole), package type (axial), and physical dimensions (0.455" Dia x 0.900" L). The substitute part 4590R-475K meets all these electrical and mechanical specifications identically. Substitution is valid when all parameters remain within the specified tolerances and the physical footprint accommodates the application's PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

The 4590R-475K serves as a direct electrical and mechanical substitute for the 4590-475K. Both parts are manufactured by API Delevan Inc. and maintain identical electrical specifications across inductance, current rating, DC resistance, and thermal operating range. The primary distinction between these parts is regulatory compliance status: the 4590-475K is RoHS non-compliant, while the 4590R-475K is ROHS3 compliant. Selection between these parts should be based on the specific regulatory requirements of the end application and target market. Both parts carry Active product status and are suitable for new designs. The REACH Unaffected designation and EAR99 export classification apply uniformly to both options.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-475K replace the 4590-475K in existing designs?

A: Yes. The 4590R-475K is electrically and mechanically equivalent to the 4590-475K. All critical parameters including inductance, current rating, DC resistance, core material, shielding, mounting type, package configuration, and physical dimensions are identical. Direct substitution is valid from a functional standpoint.

Q: What is the difference between the 4590-475K and 4590R-475K?

A: The primary difference is RoHS compliance status. The 4590-475K is RoHS non-compliant, while the 4590R-475K is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical inductance, current handling, and DC resistance characteristics.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 4590-475K and 4590R-475K measure 0.455" diameter by 0.900" length (11.55mm x 22.86mm). They are pin-compatible and occupy identical PCB footprints.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, specify the 4590R-475K. If RoHS compliance is not a requirement, either part is acceptable. Both are Active products with current manufacturing support.

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

A: Yes. The electrical performance is identical. Both parts operate across the same temperature range (-55°C to 125°C), maintain the same inductance tolerance (±10%), and support the same current rating (415 mA).
