Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4564-103J is based on strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 10 mH
• Inductance tolerance: ±5%
• Current rating: 40 mA minimum
• DC resistance: 40 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Self resonant frequency: 400 kHz
• Test frequency: 79.6 kHz

Substitute parts must maintain all electrical specifications within the defined tolerances and physical dimensions compatible with through-hole radial mounting. Dimensional variations within standard manufacturing tolerances are acceptable provided the package footprint remains compatible with the original design.

Parameter Comparison

Engineering Selection Recommendations

4564-103J (API Delevan Inc.) is the primary part specification. This inductor is active in production and suitable for applications where RoHS non-compliance is acceptable and higher Q factor performance at 79.6 kHz is required.

AIUR-04-103J (Abracon LLC) is a direct electrical equivalent substitute. This part meets all critical inductance, current, and resistance specifications. The substitute provides the following advantages:

• Extended operating temperature range (-25°C to 85°C versus -20°C to 80°C)
• ROHS3 compliance for regulated applications
• Higher inventory availability (2056 pcs versus 824 pcs)
• Moisture sensitivity level 1 (Unlimited) versus Not Applicable

The AIUR-04-103J exhibits lower Q factor (40 versus 100 at 79.6 kHz). This difference must be evaluated against application requirements for frequency response and signal filtering characteristics. Physical dimensions are compatible with through-hole radial mounting, with negligible variations within standard manufacturing tolerances.

Both parts are ferrite core, unshielded, through-hole inductors with identical electrical specifications for inductance, tolerance, current rating, and DC resistance. Selection between these parts depends on compliance requirements, temperature operating range needs, and Q factor performance criteria specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can AIUR-04-103J replace 4564-103J in all applications?

A: AIUR-04-103J is electrically equivalent for inductance, current rating, and DC resistance specifications. However, the lower Q factor (40 versus 100 at 79.6 kHz) may affect frequency response in applications sensitive to inductor quality factor. Verify that the substitute's Q factor meets application filtering or resonance requirements before implementation.

Q: What are the physical compatibility considerations?

A: Both parts use radial, vertical cylinder through-hole packages with compatible dimensions. The AIUR-04-103J diameter is 0.335" (8.50 mm) versus 0.340" (8.64 mm) for the 4564-103J, and height is 0.441" (11.20 mm) versus 0.433" (11.00 mm). These variations are within standard PCB layout tolerances for through-hole radial components.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance status does not alter electrical performance. The AIUR-04-103J ROHS3 compliance indicates material composition restrictions but maintains equivalent inductance, tolerance, current rating, and DC resistance specifications. Selection based on compliance requirements depends on end-product regulatory obligations.

Q: How do the operating temperature ranges differ?

A: The 4564-103J operates from -20°C to 80°C. The AIUR-04-103J extends this range to -25°C to 85°C, providing 5°C additional margin at both temperature extremes. Applications requiring operation below -20°C or above 80°C must use the AIUR-04-103J substitute.

Q: What is the significance of the Q factor difference?

A: Q factor at 79.6 kHz is 100 for the 4564-103J and 40 for the AIUR-04-103J. Higher Q indicates lower energy loss and sharper frequency response. Applications using these inductors in resonant circuits, filters, or impedance matching networks should verify that the lower Q factor of the substitute does not degrade performance specifications.

Q: Are there moisture sensitivity differences?

A: The 4564-103J lists moisture sensitivity as Not Applicable. The AIUR-04-103J is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This difference does not affect electrical performance but may influence storage and handling procedures for the substitute part.
