S0402-10NG3D Equivalent & Substitute Parts

Part Overview

The S0402-10NG3D 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 maximum DC resistance of 210 mOhm and supports a current rating of 475 mA. The part is currently in active production status with 1,063 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. The primary driver for seeking alternatives includes inventory availability, lead time optimization, and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S0402-10NG3D is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 10 nH (±2% tolerance)
• Package classification: 0402 (1005 Metric)
• Mounting type: Surface Mount
• Core construction: Drum Core, Wirewound
• Shielding configuration: Unshielded

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 475 mA
• DC resistance: Substitute must not exceed 210 mOhm maximum
• Operating temperature range: Substitute must cover or exceed -55°C to 125°C
• Core material: Alumina or Ceramic acceptable for this inductance class

The substitute part LRW0402WG10NGG001T meets all critical matching parameters and operates within allowable variation limits for current rating and DC resistance specifications.

Engineering Selection Recommendations

Primary Part: S0402-10NG3D

Selection of the S0402-10NG3D is appropriate when:

• RoHS non-compliant designs are acceptable
• Operating temperature range must extend to -55°C minimum
• Alumina core material is specified in design requirements
• API Delevan Inc. supply chain is preferred

Substitute Part: LRW0402WG10NGG001T

The LRW0402WG10NGG001T from Johanson Technology Inc. is electrically and mechanically compatible with the S0402-10NG3D. Selection of this substitute is appropriate when:

• ROHS3 compliance is required
• Operating temperature minimum of -40°C is acceptable
• Ceramic core material is acceptable in design specifications
• Improved inventory availability is required (35,881 pieces in stock versus 1,063 pieces)
• Lower DC resistance (195 mOhm versus 210 mOhm maximum) provides performance margin
• Higher current rating (480 mA versus 475 mA) provides operational headroom

Both parts carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications. Both are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WG10NGG001T be used as a direct replacement for S0402-10NG3D in all applications?

A: The LRW0402WG10NGG001T is electrically and mechanically compatible for applications where the operating temperature range of -40°C to 125°C is acceptable. If your design requires operation below -40°C, the S0402-10NG3D must be used. Both parts are identical in inductance value, tolerance, package size, and mounting type.

Q: What is the difference in core material between these two parts?

A: The S0402-10NG3D uses an Alumina core, while the LRW0402WG10NGG001T uses a Ceramic core. Both materials are acceptable for 10 nH drum core wirewound inductors in the 0402 package. The ceramic core in the substitute part results in lower DC resistance (195 mOhm versus 210 mOhm maximum).

Q: Does the physical size difference affect PCB layout?

A: Both parts conform to the 0402 (1005 Metric) package specification. The LRW0402WG10NGG001T has slightly smaller physical dimensions (1.00mm x 0.55mm versus 1.09mm x 0.64mm) and lower seated height (0.60mm versus 0.76mm maximum). These differences remain within the 0402 package envelope and do not require PCB layout modification.

Q: What is the significance of the RoHS compliance difference?

A: The S0402-10NG3D is RoHS non-compliant, while the LRW0402WG10NGG001T is ROHS3 compliant. Selection depends on your product's regulatory requirements. If ROHS3 compliance is mandatory, the LRW0402WG10NGG001T must be used.

Q: Are there any frequency-dependent performance differences?

A: Both parts share identical self-resonant frequency (3.9 GHz) and inductance test frequency (250 MHz). The Q factor differs at different test frequencies (20 @ 250MHz for S0402-10NG3D versus 56 @ 900MHz for LRW0402WG10NGG001T), but both are measured at different frequencies and are not directly comparable.

Q: Which part should I select for new designs?

A: For new designs, the LRW0402WG10NGG001T is recommended when operating temperature requirements permit, due to superior inventory availability, ROHS3 compliance, and improved electrical margins (lower DCR, higher current rating). The S0402-10NG3D should be selected only when specific design requirements mandate Alumina core material or extended low-temperature operation to -55°C.
