S0402-10NG3S Equivalent & Substitute Parts

Part Overview

The S0402-10NG3S is a 10 nH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications in the 0402 (1005 Metric) package. This component operates across a temperature range of -55°C to 125°C with a current rating of 475 mA and maximum DC resistance of 210 mOhm. The part is currently active in production with 910 pieces available in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. Alternative sources may be required due to supply chain considerations, lead time requirements, or specific compliance certifications needed for end-use applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S0402-10NG3S is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 nH (±2% tolerance)
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount
• Component Type: Drum Core, Wirewound
• Shielding: Unshielded

Allowable Parameter Ranges for Substitution:

• Current Rating: Minimum 475 mA (equal or higher acceptable)
• DC Resistance: Maximum 210 mOhm (lower values acceptable)
• Operating Temperature Range: Must encompass or exceed -55°C to 125°C
• Frequency - Self Resonant: 3.9 GHz (matching value)

The substitute part LRW0402WG10NGG001T meets all mandatory matching parameters and operates within allowable ranges for current rating (480 mA) and DC resistance (195 mOhm maximum). Both parts maintain identical inductance specifications and package dimensions suitable for direct board-level substitution.

Engineering Selection Recommendations

S0402-10NG3S (API Delevan Inc.):

• Product Status: Active
• RoHS Status: Non-compliant
• REACH Status: Unaffected
• Operating Temperature: -55°C to 125°C
• Suitable for applications requiring extended low-temperature operation down to -55°C

LRW0402WG10NGG001T (Johanson Technology Inc.):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: Unaffected
• Operating Temperature: -40°C to 125°C
• Suitable for applications requiring RoHS3 compliance; minimum operating temperature limited to -40°C

Selection between these parts depends on compliance requirements and minimum operating temperature specifications. The Johanson Technology part provides superior RoHS3 compliance certification and lower DC resistance (195 mOhm vs. 210 mOhm), resulting in reduced power dissipation. The API Delevan part extends operational capability to -55°C for applications requiring extended low-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WG10NGG001T directly replace S0402-10NG3S in all applications?

A: Direct substitution is possible for applications operating at temperatures above -40°C. The S0402-10NG3S must be used for systems requiring operation below -40°C, as the Johanson part is rated only to -40°C minimum. Both parts share identical inductance (10 nH), package (0402), and mounting characteristics.

Q: What is the significance of the DC resistance difference (210 mOhm vs. 195 mOhm)?

A: The lower DC resistance of the LRW0402WG10NGG001T (195 mOhm) results in reduced resistive losses and lower heat generation at equivalent current levels. This 7.3% reduction in maximum resistance improves efficiency in high-frequency applications and reduces thermal stress on the component.

Q: Are both parts suitable for high-frequency applications?

A: Both parts are designed for high-frequency operation with self-resonant frequencies of 3.9 GHz. The LRW0402WG10NGG001T exhibits higher Q factor (56 @ 900 MHz) compared to the S0402-10NG3S (20 @ 250 MHz), indicating superior performance in the 900 MHz frequency band.

Q: What packaging formats are available for these parts?

A: The S0402-10NG3S is supplied in standard packaging format. The LRW0402WG10NGG001T is available in Cut Tape (CT) packaging. Both maintain the 0402 (1005 Metric) component package specification for surface mount assembly.

Q: How do the physical dimensions compare?

A: Both parts conform to the 0402 (1005 Metric) package standard. The LRW0402WG10NGG001T has a slightly smaller footprint (1.00mm x 0.55mm vs. 1.09mm x 0.64mm) and lower seated height (0.60mm vs. 0.76mm), providing improved board space efficiency while maintaining full electrical compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. For applications requiring RoHS3 compliance and operating above -40°C, the LRW0402WG10NGG001T is preferred due to superior compliance certification and lower DC resistance. For applications requiring extended low-temperature operation to -55°C, the S0402-10NG3S is required.
