AIAP-03-332K Equivalent & Substitute Parts

Part Overview

The AIAP-03-332K is a 3.3 mH unshielded wirewound inductor manufactured by Abracon LLC, rated for 470 mA continuous current with a maximum DC resistance of 2.63 Ohm. This through-hole axial component operates across the industrial temperature range of -55°C to 125°C and maintains active product status with full RoHS3 compliance. Substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative electrical characteristics better suit specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

The 4590R-335K from API Delevan Inc. qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Inductance value matches at 3.3 mH with identical ±10% tolerance. Current rating of 510 mA exceeds the primary part's 470 mA specification, providing margin for circuit operation. DC resistance of 2.53 Ohm is lower than the 2.63 Ohm maximum, reducing power dissipation. Both components feature unshielded construction, identical through-hole axial mounting, and operate across the same -55°C to 125°C temperature range. Physical dimensions are equivalent within manufacturing tolerances (0.455" Dia x 0.900" L versus 0.449" Dia x 0.902" L). Both maintain RoHS3 compliance and EAR99 export classification.

Parameter Comparison

Engineering Selection Recommendations

Both the AIAP-03-332K and 4590R-335K maintain active product status with full regulatory compliance. The 4590R-335K offers improved electrical performance through lower DC resistance (2.53 Ohm versus 2.63 Ohm) and higher current rating (510 mA versus 470 mA), resulting in reduced power dissipation and increased thermal margin in the application circuit. Physical form factors are compatible for through-hole PCB mounting. Selection between these parts should be based on availability, lead time, and specific circuit thermal or efficiency requirements within the defined parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-335K replace the AIAP-03-332K in existing designs?

A: Yes. Both inductors share identical inductance values (3.3 mH), tolerance (±10%), unshielded construction, axial through-hole mounting, and operating temperature range (-55°C to 125°C). The 4590R-335K provides equivalent or superior electrical performance with lower DC resistance and higher current rating.

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

A: The AIAP-03-332K uses wirewound construction on an unspecified core material. The 4590R-335K uses drum core ferrite wirewound construction. Both deliver the same inductance value and tolerance at the specified 1 kHz test frequency.

Q: Are there physical dimension differences that affect PCB layout?

A: Dimensions are equivalent within manufacturing tolerances. AIAP-03-332K measures 0.449" Dia x 0.902" L (11.40mm x 22.90mm). The 4590R-335K measures 0.455" Dia x 0.900" L (11.55mm x 22.86mm). Both fit standard through-hole axial component footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level differs (MSL 1 for AIAP-03-332K, not applicable for 4590R-335K), but this does not affect substitution compatibility.

Q: Which part should be selected for thermal-sensitive applications?

A: The 4590R-335K is preferable due to lower DC resistance (2.53 Ohm versus 2.63 Ohm), which reduces resistive heating at rated current levels.
