AIAP-03-560K Equivalent & Substitute Parts

Part Overview

The AIAP-03-560K is a 56 µH unshielded wirewound inductor manufactured by Abracon LLC, rated for 3.66 A continuous current with a maximum DC resistance of 37mOhm. This through-hole axial component operates across the industrial temperature range of -55°C to 125°C and maintains ROHS3 compliance. The part is currently active in production with 680 units in stock. Substitute parts are identified when equivalent inductance values, current ratings, and mechanical compatibility requirements can be met by alternative manufacturers while maintaining the same functional specifications and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AIAP-03-560K are qualified based on the following critical parameters:

• Inductance Value: Must be 56 µH with ±10% tolerance
• Current Rating: Must meet or exceed 3.66 A continuous current capability
• DC Resistance: Must not exceed 37mOhm to maintain equivalent power dissipation characteristics
• Mounting Type: Must be through-hole axial configuration
• Package Compatibility: Physical dimensions must be compatible with 0.449" diameter and 0.902" length envelope
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status
• Operating Temperature: Must support -55°C to 125°C range or equivalent industrial specification

The identified substitutes meet these criteria while originating from different manufacturers (API Delevan Inc. and Bourns Inc.), providing supply chain alternatives without compromising circuit performance.

Parameter Comparison

Engineering Selection Recommendations

4590R-563K (API Delevan Inc.) is the primary substitute option. This part exceeds the current rating requirement at 3.93 A and maintains ROHS3 compliance with identical operating temperature range (-55°C to 125°C). The DCR specification of 43mOhm Max represents a 16% increase over the original part, which remains within acceptable tolerance for most applications. Physical dimensions are equivalent within manufacturing tolerances. Product status is active with 1202 units in stock.

5900-560-RC (Bourns Inc.) is a secondary substitute option with limitations. While ROHS3 compliant and dimensionally compatible, the current rating of 2.9 A falls below the original 3.66 A specification, making this part unsuitable for applications requiring the full rated current. The DCR specification of 50mOhm Max represents a 35% increase over the original part. Additionally, the operating temperature range is limited to -55°C to 105°C, which does not support the full 125°C upper limit of the original specification. This part is suitable only for applications with reduced current requirements and lower maximum operating temperatures.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-563K directly replace the AIAP-03-560K in all applications?

A: The 4590R-563K meets or exceeds all critical electrical parameters of the AIAP-03-560K, including inductance, current rating, and operating temperature range. Physical dimensions are equivalent within standard manufacturing tolerances for axial through-hole components. Direct substitution is appropriate for standard circuit applications.

Q: What is the impact of increased DC resistance in substitute parts?

A: The 4590R-563K exhibits 43mOhm Max DCR compared to 37mOhm Max in the original part. This 6mOhm increase results in proportionally higher resistive losses. In applications where power dissipation is critical, calculate the thermal impact using I²R losses at the maximum rated current. The 5900-560-RC with 50mOhm Max DCR presents greater thermal considerations and is not recommended as a direct substitute.

Q: Why is the 5900-560-RC listed as a substitute if it has lower current rating?

A: The 5900-560-RC is identified as a substitute for applications where the circuit current requirement does not exceed 2.9 A. It is not a universal substitute for the AIAP-03-560K. Circuit designers must confirm that their application operates below this current threshold and within the -55°C to 105°C temperature range before selecting this part.

Q: Are there mechanical compatibility concerns between these axial inductors?

A: All three parts are through-hole axial components with equivalent physical envelopes. Diameter variations range from 0.449" to 0.455" and lengths from 0.900" to 0.902", which fall within standard PCB hole tolerances and component spacing requirements. No mechanical redesign is required for substitution.

Q: Do all substitute parts maintain the same compliance certifications?

A: All parts listed are ROHS3 compliant and REACH unaffected. Moisture sensitivity level differs: the original AIAP-03-560K is MSL 1 (Unlimited), while both substitutes are not applicable for MSL rating. This distinction does not affect functionality but may impact storage and handling procedures in moisture-sensitive environments.
