Parameter Comparison

Engineering Selection Recommendations

Both the AIAP-03-152K and 4590R-155K meet the electrical and mechanical requirements for 1.5 mH axial wirewound inductor applications. Selection between these parts should be based on:

Availability: The 4590R-155K offers higher inventory availability (1115 units) compared to the AIAP-03-152K (663 units).

Current Margin: The 4590R-155K provides a 50 mA higher current rating (750 mA vs. 700 mA), offering additional operational margin in current-limited applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting equivalent environmental and regulatory requirements.

Physical Compatibility: Axial package dimensions are within acceptable tolerance for standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-155K replace the AIAP-03-152K in existing designs?

A: Yes. Both inductors share identical electrical specifications (1.5 mH, ±10% tolerance, 1.18Ohm DCR) and operate across the same temperature range (-55°C to 125°C). The axial through-hole package and unshielded configuration are identical. The 4590R-155K's higher current rating (750 mA) is compatible with applications designed for 700 mA.

Q: Are there physical footprint differences between these parts?

A: Dimensions are comparable. AIAP-03-152K measures 0.449" Dia × 0.902" L; 4590R-155K measures 0.455" Dia × 0.900" L. Both fit standard axial component spacing on through-hole PCBs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant and REACH Unaffected, meeting equivalent environmental and regulatory requirements for industrial applications.

Q: What is the difference in core material?

A: The AIAP-03-152K uses a standard wirewound core, while the 4590R-155K uses a drum core with ferrite material. Both achieve the same 1.5 mH inductance and DC resistance specifications.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain requirements and inventory availability. Both parts are electrically and mechanically equivalent for this application category.
