Substitute Part Grouping Explanation

The 4590R-565K from API Delevan Inc. qualifies as a substitute for the AIAP-03-562K based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance value: 5.6 mH (identical)
• Inductance tolerance: ±10% (identical)
• Shielding classification: Unshielded (identical)
• Mounting type: Through Hole (identical)
• Package type: Axial (identical)
• Operating temperature range: -55°C to 125°C (identical)
• Inductance test frequency: 1 kHz (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Acceptable Parameter Variations:

• Current rating: 395 mA (substitute) vs. 359 mA (main part) — substitute exceeds minimum requirement
• DC resistance: 4.24Ohm Max (substitute) vs. 3.92Ohm Max (main part) — within acceptable tolerance for equivalent inductance class
• Physical dimensions: 0.455" Dia x 0.900" L (substitute) vs. 0.449" Dia x 0.902" L (main part) — negligible variation, compatible with standard through-hole PCB layouts

Parameter Comparison

Engineering Selection Recommendations

Both the AIAP-03-562K and 4590R-565K are active production components with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The 4590R-565K provides higher current capacity (395 mA vs. 359 mA), making it suitable for applications requiring additional thermal margin. The slightly elevated DC resistance (4.24Ohm vs. 3.92Ohm) remains within the tolerance band for 5.6 mH inductors at 1 kHz test frequency. Both components maintain identical operating temperature specifications and axial through-hole form factors, ensuring mechanical and thermal compatibility in standard PCB designs. Selection between these parts should be based on availability, lead time, and specific circuit current requirements within the stated ratings.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-565K directly replace the AIAP-03-562K in existing designs?

A: Yes. Both components share identical inductance values (5.6 mH), tolerance (±10%), shielding classification (unshielded), mounting type (through-hole), and package type (axial). Physical dimensions are within acceptable tolerance for standard PCB hole spacing. The substitute part's higher current rating (395 mA) and marginally higher DC resistance (4.24Ohm) do not prevent direct substitution in circuits designed for the original part's specifications.

Q: What is the significance of the DC resistance difference between these parts?

A: The AIAP-03-562K specifies 3.92Ohm maximum DCR, while the 4590R-565K specifies 4.24Ohm maximum DCR. This 0.32Ohm difference represents approximately 8% variation and is typical among inductors of equivalent inductance class. For most filtering and energy storage applications, this variation falls within acceptable circuit tolerance. Applications with strict power dissipation budgets should verify the substitute part's DCR impact on total circuit losses.

Q: Are there temperature or compliance differences between these parts?

A: No. Both components operate across -55°C to 125°C and maintain identical ROHS3 compliance and REACH unaffected status. Both are classified as EAR99 for export control purposes. Regulatory and environmental specifications are equivalent.

Q: How do the physical dimensions affect PCB layout compatibility?

A: The AIAP-03-562K measures 0.449" diameter by 0.902" length, while the 4590R-565K measures 0.455" diameter by 0.900" length. These differences are negligible (approximately 0.006" and 0.002" respectively) and do not affect standard through-hole PCB designs with conventional lead spacing. Both components fit within identical footprint allowances.

Q: What core material differences exist between these inductors?

A: The AIAP-03-562K uses an unspecified core material, while the 4590R-565K employs a ferrite drum core construction. Both maintain unshielded classification and identical inductance specifications at 1 kHz test frequency. The ferrite core in the substitute part contributes to its higher current saturation rating (240 mA Isat) and slightly elevated DCR.
