S0402-22NJ3D Equivalent & Substitute Parts

Part Overview

The S0402-22NJ3D is a 22 nH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications in the 0402 (1005 Metric) package. This active product operates within a -55°C to 125°C temperature range with a 400 mA current rating and 350mOhm maximum DC resistance. Alternative equivalent parts are necessary to address supply chain requirements, inventory availability, and application-specific compliance needs such as RoHS and AEC-Q200 certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S0402-22NJ3D are qualified based on matching the following critical electrical and mechanical parameters:

• Inductance Value: 22 nH ±5% tolerance
• Current Rating: 400 mA minimum
• Package Footprint: 0402 (1005 Metric) surface mount
• Mounting Type: Surface mount configuration
• Shielding Configuration: Unshielded
• Self Resonant Frequency: 2.8GHz
• Inductance Test Frequency: 250 MHz

The qualified substitutes (744765122A and CW100505-22NJ) maintain electrical performance equivalence through matching inductance, current rating, and frequency characteristics. Both alternatives accept a maximum DC resistance specification of 300mOhm, which is lower than the S0402-22NJ3D specification of 350mOhm Max, providing equivalent or superior performance in this parameter. Physical dimensions remain compatible with 0402 package placement.

Parameter Comparison

Engineering Selection Recommendations

API Delevan Inc. S0402-22NJ3D: This original part is active and suitable for general applications. The part is RoHS non-compliant and lacks AEC-Q200 automotive certification, which may limit use in regulated industries or automotive applications.

Würth Elektronik 744765122A: This substitute is active with RoHS3 compliance and AEC-Q200 automotive rating certification, making it suitable for automotive and regulated applications requiring enhanced quality assurance. The component offers equivalent electrical performance with improved DC resistance specification (300mOhm Max) compared to the original part. Tape & Reel packaging is available.

Bourns Inc. CW100505-22NJ: This substitute is active with RoHS3 compliance. It matches the operating temperature range of the original part (-55°C ~ 125°C) and provides equivalent electrical performance with improved DC resistance (300mOhm). Tape & Reel packaging is available.

Selection between substitutes should prioritize application requirements regarding compliance certifications and supply chain availability. The Würth Elektronik 744765122A is preferred for automotive applications due to AEC-Q200 certification. The Bourns CW100505-22NJ offers compatibility across all temperature range requirements of the original specification.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable with the S0402-22NJ3D?

A: Yes. All substitute parts maintain the specified 22 nH inductance at 250 MHz test frequency with ±5% tolerance, 400 mA current rating, 2.8GHz self-resonant frequency, and unshielded drum core configuration. The lower maximum DC resistance specifications of the substitutes (300mOhm Max versus 350mOhm Max) represent equivalent or improved performance.

Q: What is the impact of the dimensional differences between parts?

A: The S0402-22NJ3D is slightly larger (1.09mm x 0.64mm with 0.76mm maximum height) compared to the Würth and Bourns substitutes (1.00mm x 0.55mm with 0.60mm maximum height). Both dimensions comply with 0402 (1005 Metric) package specifications. The smaller footprint of the substitute parts provides compatibility with standard 0402 placement in PCB layouts.

Q: Which substitute part should be selected for automotive applications?

A: The Würth Elektronik 744765122A is qualified with AEC-Q200 certification for automotive use. The S0402-22NJ3D and Bourns CW100505-22NJ lack this certification and are not suitable for regulated automotive applications.

Q: Are there temperature range limitations when substituting these parts?

A: The Würth Elektronik 744765122A operates from -40°C to 125°C, which is narrower than both the S0402-22NJ3D and Bourns CW100505-22NJ (-55°C to 125°C). Selection of the Würth part should consider application minimum operating temperature requirements.

Q: Are all parts available in tape and reel packaging?

A: The S0402-22NJ3D packaging type is not specified as tape and reel in the provided data. Both substitute parts (744765122A and CW100505-22NJ) are available in Tape & Reel (TR) packaging, which is standard for high-volume SMD assembly.

Q: What compliance differences exist between these parts?

A: The S0402-22NJ3D is RoHS non-compliant. Both substitute parts meet RoHS3 compliance requirements. The Würth Elektronik 744765122A includes AEC-Q200 automotive qualification; the other parts do not carry this certification. All parts are REACH unaffected and classified under EAR99 export control.
