S0402-10NG2E Equivalent & Substitute Parts Reference

Part Overview

The S0402-10NG2E 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 active in production with 690 pieces available in inventory.

Substitute components become necessary when the original part experiences supply constraints, extended lead times, or when design requirements permit alternative specifications within acceptable electrical and mechanical tolerances. Equivalent parts must maintain the same inductance value, package form factor, and core operating characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S0402-10NG2E is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

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

Secondary Compatibility Parameters:

• Current rating: Minimum 475 mA (substitute must meet or exceed)
• DC resistance: Maximum 210 mOhm (substitute must not exceed)
• Operating temperature range: Must encompass or match the -55°C to 125°C specification
• Frequency characteristics: Self-resonant frequency at or above 3.9 GHz

The substitute part LRW0402WG10NGG001T meets all primary substitution criteria and demonstrates equivalent or superior performance in secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Feasibility:

The LRW0402WG10NGG001T from Johanson Technology Inc. qualifies as a direct substitute for the S0402-10NG2E based on electrical and mechanical parameter alignment. Both components share identical inductance specifications (10 nH ±2%), package dimensions (0402 metric), core configuration (drum core wirewound), and shielding characteristics (unshielded).

Performance Advantages of Substitute:

The substitute component demonstrates superior electrical performance with a lower maximum DC resistance (195 mOhm versus 210 mOhm) and a marginally higher current rating (480 mA versus 475 mA). These characteristics indicate improved efficiency and thermal performance in equivalent circuit applications.

Compliance Considerations:

The LRW0402WG10NGG001T carries ROHS3 compliance certification, whereas the S0402-10NG2E is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements in regions enforcing RoHS directives. Both components maintain REACH unaffected status and EAR99 export classification.

Temperature Range Limitation:

The substitute component operates across a narrower temperature range (-40°C to 125°C) compared to the original part (-55°C to 125°C). Applications requiring operation below -40°C must retain the S0402-10NG2E or identify alternative substitutes with extended low-temperature specifications.

Physical Dimensions:

The substitute exhibits a smaller physical footprint (1.00mm x 0.55mm versus 1.09mm x 0.64mm) and lower seated height (0.60mm versus 0.76mm). These dimensional differences may provide layout advantages in space-constrained designs while maintaining full electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LRW0402WG10NGG001T replace the S0402-10NG2E in all applications?

A: Direct substitution is permissible for applications operating within the -40°C to 125°C temperature range. Applications requiring operation below -40°C must retain the original S0402-10NG2E or identify alternative components with extended low-temperature ratings.

Q: What are the critical parameters that must match for substitution?

A: Inductance value (10 nH), inductance tolerance (±2%), package form factor (0402 metric), mounting type (surface mount), core configuration (drum core wirewound), and shielding type (unshielded) must remain identical. Current rating and DC resistance specifications of the substitute must meet or exceed the original component requirements.

Q: Does the smaller physical size of the substitute affect circuit performance?

A: The reduced dimensions of the LRW0402WG10NGG001T do not alter electrical performance characteristics. Both components maintain identical inductance values, self-resonant frequencies (3.9 GHz), and Q-factor specifications at their respective test frequencies. The dimensional difference reflects manufacturing process variations between manufacturers and does not impact functional compatibility.

Q: Is RoHS compliance a factor in selecting between these components?

A: RoHS compliance status depends on application requirements and regional regulations. The substitute (LRW0402WG10NGG001T) is ROHS3 compliant, while the original (S0402-10NG2E) is non-compliant. Applications subject to RoHS directives must use the compliant substitute or identify alternative compliant sources for the original part number.

Q: What is the impact of the lower DC resistance in the substitute component?

A: Lower DC resistance (195 mOhm versus 210 mOhm) in the substitute results in reduced resistive losses and improved thermal efficiency. This characteristic is advantageous in high-frequency applications and circuits operating at elevated current levels near the component's current rating.

Q: Are there packaging differences between these components?

A: The original S0402-10NG2E is supplied in standard packaging format, while the substitute LRW0402WG10NGG001T is available in Cut Tape (CT) packaging. Both formats are compatible with standard surface mount assembly processes. Packaging selection should align with production volume and assembly equipment specifications.

Q: Can these components be used interchangeably in PCB designs?

A: Yes, both components are compatible with identical PCB footprints (0402 metric). The substitute's smaller physical dimensions provide additional clearance margins in space-constrained layouts. No PCB redesign is required for substitution.
