AIAP-03-5R6K Equivalent & Substitute Parts

Part Overview

The AIAP-03-5R6K is a 5.6 µH unshielded wirewound inductor manufactured by Abracon LLC, rated for 12.6 A continuous current with a maximum DC resistance of 11 mOhm. 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 892 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the AIAP-03-5R6K is determined by the following criteria:

• Inductance value must be 5.6 µH within ±10% tolerance
• DC resistance must not exceed 11 mOhm maximum
• Operating temperature range must encompass -55°C to 125°C
• Mounting type must be through-hole axial configuration
• Shielding characteristic must be unshielded
• RoHS3 compliance is required

The substitute part 4590R-562K meets these core electrical and mechanical requirements. However, the current rating differs between the main part (12.6 A) and the substitute (7.77 A), which represents a functional limitation that must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 4590R-562K from API Delevan Inc. qualifies as an electrical and mechanical substitute based on matching inductance, tolerance, DC resistance, temperature range, and axial through-hole configuration. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The primary design consideration is the reduced current rating of the substitute part (7.77 A versus 12.6 A). Selection between these parts depends on the actual circuit current requirements. If circuit operation requires sustained current above 7.77 A, the AIAP-03-5R6K is the appropriate choice. For applications operating within the 7.77 A limit, the 4590R-562K provides functional equivalence with identical inductance and DC resistance characteristics.

Physical dimensions are comparable between both parts, with negligible differences in diameter and length that do not affect standard through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-562K be used in place of the AIAP-03-5R6K in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 7.77 A continuous. The 4590R-562K has a lower current rating (7.77 A) compared to the AIAP-03-5R6K (12.6 A). If your circuit operates above this threshold, the original part is required.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Both parts are axial through-hole components with nearly identical dimensions (0.449" to 0.455" diameter, 0.900" to 0.902" length). They are mechanically interchangeable on standard PCB layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AIAP-03-5R6K and 4590R-562K are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in core construction between these parts?

A: The AIAP-03-5R6K uses a wirewound construction without specified core material. The 4590R-562K uses a drum core ferrite wirewound construction. Both deliver the same 5.6 µH inductance and 11 mOhm maximum DC resistance.

Q: How do I determine which part to select for my design?

A: Evaluate your circuit's maximum sustained current requirement. If it exceeds 7.77 A, use the AIAP-03-5R6K. If it remains below 7.77 A, either part is acceptable. Both parts deliver identical inductance and resistance characteristics within the specified tolerance.
