4564-471J Fixed Inductor Equivalent & Substitute Parts

Part Overview

The 4564-471J is a 470 µH unshielded through-hole inductor manufactured by API Delevan Inc., designed for applications requiring fixed inductance with moderate current handling. This ferrite-core component operates across a temperature range of -20°C to 80°C and is currently in active production status with 953 units available in inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements favor alternative manufacturers with enhanced compliance certifications or improved performance characteristics within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 4564-471J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 470 µH ±5% tolerance
• Current rating: 200 mA minimum
• DC resistance: 4 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Self-resonant frequency: 1.9 MHz
• Test frequency: 796 kHz

Mechanical Equivalence Requirements:

• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Physical dimensions compatible with PCB footprint

The AIUR-04-471J from Abracon LLC meets all electrical and mechanical equivalence criteria, enabling direct substitution in circuit applications where the 4564-471J is specified.

Engineering Selection Recommendations

Primary Part Selection (4564-471J): The 4564-471J remains the preferred selection when supply availability is confirmed and RoHS non-compliance is acceptable for the application. This component delivers superior Q factor performance (80 @ 796kHz), indicating lower losses and higher efficiency in resonant circuit applications.

Substitute Part Selection (AIUR-04-471J): The AIUR-04-471J is the appropriate selection when:

• RoHS3 compliance is a design requirement
• Extended operating temperature range (-25°C to 85°C) is required
• Moisture sensitivity control (MSL 1) is specified
• Supply chain continuity for the 4564-471J is interrupted

Both components satisfy identical electrical specifications for inductance, current rating, and DC resistance. The AIUR-04-471J provides enhanced regulatory compliance and environmental handling characteristics. The lower Q factor (30 @ 796kHz) indicates slightly higher losses but remains within acceptable parameters for non-critical resonant applications.

Physical dimensions are mechanically compatible with standard through-hole PCB layouts designed for radial vertical cylinder inductors in this size class.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-04-471J directly replace the 4564-471J in existing circuit designs?

A: Yes. Both components share identical inductance (470 µH), current rating (200 mA), DC resistance (4 Ohm maximum), core material (ferrite), and mounting configuration (through-hole radial vertical cylinder). Electrical performance is equivalent for circuit operation. Physical dimensions are compatible with standard PCB footprints.

Q: What is the difference in Q factor between these two inductors?

A: The 4564-471J exhibits a Q factor of 80 @ 796kHz, while the AIUR-04-471J exhibits 30 @ 796kHz. Q factor represents the ratio of reactive power to dissipated power. The higher Q of the 4564-471J indicates lower losses in resonant circuits. For applications where resonant efficiency is critical, the 4564-471J is preferred. For general filtering and coupling applications, both Q values are acceptable.

Q: Are there compliance differences between these parts?

A: Yes. The AIUR-04-471J is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), while the 4564-471J is RoHS non-compliant with MSL not applicable. If your application or supply chain requires RoHS compliance or controlled moisture handling, the AIUR-04-471J is the appropriate selection.

Q: Do these inductors have different temperature operating ranges?

A: The 4564-471J operates from -20°C to 80°C, while the AIUR-04-471J operates from -25°C to 85°C. The AIUR-04-471J provides a wider temperature envelope. For applications requiring extended low-temperature operation below -20°C or high-temperature operation above 80°C, the AIUR-04-471J is suitable.

Q: Are the physical dimensions identical?

A: Dimensions are similar but not identical. The 4564-471J measures 0.340" diameter (8.64mm) with 0.433" maximum seated height (11.00mm). The AIUR-04-471J measures 0.335" diameter (8.50mm) with 0.441" maximum seated height (11.20mm). Both fit standard radial vertical cylinder through-hole footprints. Verify PCB layout clearances if space constraints exist.

Q: What is the current saturation rating for each part?

A: The 4564-471J does not specify a saturation current (listed as "-"). The AIUR-04-471J specifies 200mA saturation current, matching its rated current. For applications approaching maximum current limits, the AIUR-04-471J provides explicit saturation specification.
