Key Parameters

Substitute Part Grouping Explanation

The 4590R-333K from API Delevan Inc. qualifies as a direct substitute based on the following alignment of critical parameters:

• Inductance Value: Both parts specify 33 µH at 1 kHz test frequency with ±10% tolerance
• Current Rating: 4.87 A (4590R-333K) exceeds the 4.83 A requirement of the main part
• DC Resistance: 28mOhm maximum (4590R-333K) is lower than the 32mOhm maximum of AIAP-03-330K, indicating improved efficiency
• Mounting Configuration: Both are through-hole axial components with compatible physical dimensions (11.40mm vs 11.55mm diameter; 22.90mm vs 22.86mm length)
• Operating Temperature Range: Identical -55°C to 125°C specification
• Compliance: Both maintain ROHS3 compliance and REACH unaffected status
• Inductance Test Frequency: Both measured at 1 kHz

Parameter Comparison

Engineering Selection Recommendations

Both the AIAP-03-330K and 4590R-333K are active production components with full regulatory compliance. The 4590R-333K demonstrates superior electrical characteristics with a 0.04 A higher current rating and 4mOhm lower DC resistance, resulting in reduced power dissipation. Physical dimensions are compatible within standard PCB layout tolerances for axial through-hole components. Selection between these parts should be based on availability, lead time, and supplier preference, as both meet the specified electrical and mechanical requirements for 33 µH inductance applications in the 4.83 A current class.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-333K replace the AIAP-03-330K in existing designs?

A: Yes. Both parts share identical inductance values (33 µH ±10%), equivalent current ratings (4.87 A vs 4.83 A), compatible axial through-hole packaging, and matching operating temperature ranges. Physical dimensions are within standard tolerance for PCB mounting.

Q: What is the significance of the lower DC resistance in the 4590R-333K?

A: The 28mOhm maximum DC resistance of the 4590R-333K compared to 32mOhm in the AIAP-03-330K results in lower resistive losses and reduced heat generation at rated current, improving overall circuit efficiency.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical EAR99 export classification. Moisture sensitivity levels differ (MSL 1 vs Not Applicable), but this does not affect substitution suitability for standard storage and handling conditions.

Q: How do the physical dimensions compare?

A: The AIAP-03-330K measures 11.40mm diameter × 22.90mm length, while the 4590R-333K measures 11.55mm diameter × 22.86mm length. These differences are negligible for standard through-hole PCB layouts and do not prevent direct substitution.

Q: What core material differences exist?

A: The AIAP-03-330K uses an unspecified core material, while the 4590R-333K specifies a ferrite drum core. Both are unshielded wirewound designs with equivalent inductance and current handling characteristics at the specified test frequency.
