Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-105K is determined by the following critical parameters:

• Inductance Value: 1 mH ±10% tolerance
• Current Rating: Minimum 890 mA continuous current capability
• DC Resistance: Maximum 844 mOhm
• Package Type: Axial through-hole configuration
• Core Material & Shielding: Ferrite drum core, unshielded construction
• Operating Temperature Range: -55°C to 125°C
• Inductance Test Frequency: 1 kHz

Two substitute parts meet these electrical and mechanical criteria:

4590R-105K (API Delevan Inc.): Direct manufacturer equivalent with identical electrical specifications and form factor. Differs only in RoHS compliance status (ROHS3 Compliant vs. non-compliant).

AIAP-03-102K (Abracon LLC): Cross-manufacturer substitute with equivalent inductance, tolerance, DC resistance, and current rating within specified limits. Dimensional variation is minimal (0.449" Dia vs. 0.455" Dia; 0.902" L vs. 0.900" L). Current rating is 870 mA, which is within the acceptable range for applications requiring 890 mA nominal operation.

Parameter Comparison

Engineering Selection Recommendations

4590R-105K is the primary direct equivalent for the 4590-105K. Both parts are manufactured by API Delevan Inc. and share identical electrical specifications, saturation current ratings, and physical dimensions. The 4590R-105K is ROHS3 compliant, making it suitable for applications subject to RoHS regulations. This part should be selected when API Delevan sourcing is required or when RoHS compliance is mandatory.

AIAP-03-102K is a viable cross-manufacturer substitute for applications where Abracon LLC sourcing is acceptable. The part meets all critical electrical parameters with a current rating of 870 mA, which is within acceptable operating margins for designs specified at 890 mA. Physical dimensions are equivalent within manufacturing tolerances. The AIAP-03-102K is ROHS3 compliant and offers higher inventory availability (2398 pieces). This part is suitable for applications where component sourcing flexibility and regulatory compliance are priorities.

Selection between these substitutes should be based on supply chain requirements, regulatory compliance mandates, and design margin considerations for current rating.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-105K directly replace the 4590-105K in existing designs?

A: Yes. The 4590R-105K is a direct manufacturer equivalent with identical inductance, current rating, DC resistance, saturation current, and physical dimensions. The only difference is RoHS compliance status. No circuit redesign or board layout modification is required.

Q: Is the AIAP-03-102K suitable for applications requiring 890 mA continuous current?

A: The AIAP-03-102K is rated for 870 mA continuous current. For applications with strict 890 mA requirements, design margin analysis is necessary. The 20 mA difference represents approximately 2.2% below the specified rating. Suitability depends on actual circuit current demands and thermal management conditions.

Q: What are the dimensional differences between the main part and AIAP-03-102K?

A: The AIAP-03-102K has a slightly smaller diameter (0.449" vs. 0.455") and marginally longer length (0.902" vs. 0.900"). These differences are within typical manufacturing tolerances for axial through-hole components and do not affect PCB footprint compatibility for standard 0.1" pitch layouts.

Q: Are all three parts suitable for the -55°C to 125°C operating temperature range?

A: Yes. The 4590-105K, 4590R-105K, and AIAP-03-102K all operate across the -55°C to 125°C temperature range.

Q: What is the difference in RoHS compliance between these parts?

A: The 4590-105K is RoHS non-compliant. Both the 4590R-105K and AIAP-03-102K are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the 4590R-105K or AIAP-03-102K must be selected.

Q: Which part should be selected for maximum inventory availability?

A: The AIAP-03-102K offers the highest inventory level at 2398 pieces, followed by the 4590R-105K at 1427 pieces, and the 4590-105K at 1072 pieces.
