Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70F562AF-RC is determined by the following critical parameters:

• Inductance Value: Must match 56 mH with ±5% tolerance
• Core Type & Shielding: Must be ferrite core, unshielded drum core construction
• Mounting Configuration: Must support through-hole axial mounting
• Package Type: Must be axial package format
• Regulatory Compliance: Must maintain ROHS3 compliance status

The substitute part 4590R-566J meets these core substitution criteria. While the substitute exhibits different electrical performance characteristics (higher current rating and lower DC resistance), it maintains the same inductance value, core material, shielding configuration, and mounting type required for functional equivalence in applications where the 70F562AF-RC is specified.

Parameter Comparison

Engineering Selection Recommendations

The 4590R-566J from API Delevan Inc. is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications previously using the obsolete 70F562AF-RC. Both components maintain identical inductance specifications and core construction, ensuring functional compatibility in circuits designed for 56 mH ferrite core inductors with axial through-hole mounting.

The substitute part demonstrates superior electrical performance with a higher current rating (130 mA versus 36 mA) and significantly lower DC resistance (38 Ohm versus 189 Ohm). These characteristics position the 4590R-566J as suitable for applications requiring the specified inductance value without current or resistance constraints that would prevent substitution.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-566J directly replace the 70F562AF-RC in existing designs?

A: Yes. Both components share identical inductance values (56 mH), core material (ferrite), shielding configuration (unshielded), and mounting type (through-hole axial). The substitute part meets the core substitution criteria for functional equivalence.

Q: What are the differences in electrical performance between these parts?

A: The 4590R-566J provides higher current handling capability (130 mA versus 36 mA) and lower DC resistance (38 Ohm versus 189 Ohm). These differences represent improved performance characteristics that do not prevent substitution in applications designed for the original part.

Q: Are there physical size differences between the two components?

A: Yes. The 70F562AF-RC measures 0.400" diameter by 0.630" length, while the 4590R-566J measures 0.455" diameter by 0.900" length. Physical layout verification is required to confirm board-level compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 70F562AF-RC and 4590R-566J are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications requiring these certifications.

Q: What is the temperature operating range difference?

A: The 70F562AF-RC operates from -55°C to 105°C, while the 4590R-566J operates from -55°C to 125°C. The substitute part provides an extended upper temperature limit of 20°C.
