Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4426-6NC are identified based on the following critical parameters that determine functional equivalence:

Electrical Parameters (Primary Criteria):

• Inductance value: 17.5 nH ±5% tolerance
• Core material: Air (unshielded wirewound construction)
• Q factor at test frequency: 100 @ 150 MHz
• Inductance test frequency: 150 MHz

Mechanical Parameters (Secondary Criteria):

• Mounting type: Surface Mount
• Package dimensions: 6.86 mm L x 3.05 mm W x 3.18 mm H (Nonstandard)
• Packaging format: Tape & Reel (TR)

Current Rating Consideration: The 4426-6NC operates at 3 A nominal current. Substitute parts with equal or higher current ratings maintain functional compatibility within the same thermal and saturation characteristics.

The Würth Elektronik 744914117 qualifies as a substitute based on matching inductance, core material, Q factor, physical dimensions, and packaging format. The higher current rating (4 A) and specified DC resistance (4.5 mOhm Max) provide enhanced performance margins.

Engineering Selection Recommendations

API Delevan 4426-6NC Selection Criteria:

• Primary application requirement: Operating temperature range -55°C to 125°C
• RoHS non-compliant status acceptable for legacy or non-regulated applications
• Self-resonant frequency of 3 GHz suitable for ultra-high-frequency circuit designs

Würth Elektronik 744914117 Selection Criteria:

• Primary application requirement: Operating temperature range -40°C to 125°C
• ROHS3 Compliant status required for regulated or new design implementations
• AEC-Q200 automotive qualification available for automotive-grade applications
• Higher current rating (4 A) provides additional thermal margin over 3 A nominal requirement
• Specified DC resistance (4.5 mOhm Max) enables precise power loss calculations

Compliance Considerations: The Würth Elektronik 744914117 provides ROHS3 compliance and AEC-Q200 certification, making it suitable for applications requiring regulatory adherence or automotive-grade reliability. The API Delevan 4426-6NC remains appropriate for applications where RoHS compliance is not mandated.

Temperature Range Consideration: The API Delevan component supports extended low-temperature operation (-55°C minimum) compared to the Würth Elektronik substitute (-40°C minimum). Selection depends on specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744914117 directly replace the API Delevan 4426-6NC in existing designs?

A: Direct replacement is possible when the operating temperature range does not require operation below -40°C and RoHS compliance is acceptable. The matching inductance (17.5 nH), tolerance (±5%), core material (air), shielding (unshielded), Q factor (100 @ 150 MHz), and physical dimensions (6.86 x 3.05 x 3.18 mm) ensure electrical and mechanical compatibility. The higher current rating (4 A vs. 3 A) is a performance enhancement.

Q: What is the significance of the different self-resonant frequencies (3 GHz vs. 2.2 GHz)?

A: Self-resonant frequency defines the upper frequency limit where the inductor maintains inductive behavior. The API Delevan 4426-6NC (3 GHz) extends usable frequency range compared to the Würth Elektronik 744914117 (2.2 GHz). For applications operating below 2.2 GHz, both components are equivalent. For applications requiring operation between 2.2 GHz and 3 GHz, the API Delevan component is required.

Q: Are both components available in identical packaging?

A: Yes. Both the API Delevan 4426-6NC and Würth Elektronik 744914117 are supplied in Tape & Reel (TR) format with identical nonstandard package dimensions (6.86 mm L x 3.05 mm W x 3.18 mm H maximum seated height). PCB footprint and pick-and-place compatibility are identical.

Q: What does the DC resistance specification (4.5 mOhm Max) on the Würth Elektronik part indicate?

A: DC resistance represents the ohmic loss of the inductor windings. The specified 4.5 mOhm maximum value on the Würth Elektronik 744914117 enables precise calculation of power dissipation and thermal performance. The API Delevan 4426-6NC does not provide a specified DC resistance value in available documentation.

Q: Which part should be selected for new designs?

A: For new designs requiring regulatory compliance, the Würth Elektronik 744914117 is recommended due to ROHS3 compliance and AEC-Q200 automotive qualification. For legacy designs or applications without compliance requirements, either component is suitable based on specific temperature and frequency requirements.

Q: Is the higher current rating (4 A) of the Würth Elektronik part a disadvantage?

A: No. A higher current rating indicates the component can safely handle greater current without saturation or thermal degradation. This provides design margin and is not a disadvantage for applications requiring 3 A or less.
