Equivalent & Substitute Parts for 4590-104K

Part Overview

The API Delevan Inc. 4590-104K is a 100 µH unshielded drum core wirewound inductor rated for 2.815 A with a maximum DC resistance of 84 mOhm. This through-hole axial component is designed for applications requiring fixed inductance in the 100 µH range with moderate current handling capabilities and is currently in active production status.

Alternative models may be required due to supply chain constraints, RoHS compliance requirements, or specific application needs where component substitution parameters remain within acceptable engineering tolerances.

Engineering Selection Recommendations

4590R-104K (Direct Substitute - Recommended for RoHS3 Compliance)

The 4590R-104K represents the preferred substitute when regulatory compliance is a requirement. This part is manufactured by the same supplier as the primary component and maintains identical electrical and mechanical specifications. The RoHS3 compliance status offers advantages in regulated markets and modern procurement environments.

AIAP-03-101K (Alternative Substitute - Compatible with Minor Parameter Variance)

The AIAP-03-101K from Abracon LLC provides functional equivalency with the following considerations: current rating of 2.79 A remains within acceptable operating margins (0.56% reduction), DC resistance of 90 mOhm falls within practical tolerance limits, and physical dimensions differ marginally (0.006" diameter reduction, 0.002" length increase) which remains compatible with standard through-hole PCB layouts. RoHS3 compliance is provided by this alternative.

Both substitute parts operate within the specified temperature range and maintain the required unshielded axial configuration.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 4590-104K with the 4590R-104K without design changes?

A: Yes. The 4590R-104K maintains identical inductance, current rating, DC resistance, and physical dimensions as the primary part. No PCB layout modifications are required.

Q: What is the primary difference between the 4590-104K and 4590R-104K?

A: The 4590R-104K is RoHS3 compliant, while the 4590-104K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Can the AIAP-03-101K serve as a substitute in all applications?

A: The AIAP-03-101K is functionally compatible within the specified operating parameters. The 0.56% reduction in current rating and 7.1% increase in DC resistance remain within acceptable engineering tolerances for most applications. Physical dimensions vary by less than 0.2%, maintaining through-hole PCB compatibility.

Q: Are there inventory or availability differences between these parts?

A: Inventory levels are provided as reference data only and are subject to change. Availability should be confirmed through current supplier catalogs at the time of component selection.

Q: What mounting considerations apply to these substitute parts?

A: All three parts utilize through-hole axial mounting configuration. Spacing and lead geometry remain compatible with standard 100 mil PCB grid layouts.

Q: Do these inductors require any special handling or storage conditions?

A: Storage and handling information is not provided in the available technical data. Consult manufacturer datasheets for specific environmental requirements.

Q: Which substitute part should I select for new designs?

A: For new designs, the 4590R-104K or AIAP-03-101K are both suitable selections based on RoHS3 compliance requirements and supply chain availability. Component selection should consider supplier relationships, inventory availability, and long-term supply continuity.
