S0402-27NG3C Equivalent & Substitute Parts Reference

Part Overview

The S0402-27NG3C is a 27 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 at 400 mA current rating with a maximum DC resistance of 360 mOhm and is classified as Active product status. The inductor is specified for operation across -55°C to 125°C temperature range with a self-resonant frequency of 2.48 GHz.

Substitute parts are identified when equivalent inductance values, current ratings, package dimensions, and core shielding characteristics align within the specified tolerance and performance parameters. Alternative sources become necessary for supply chain continuity, inventory availability, or compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S0402-27NG3C is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 27 nH (±2% tolerance maintained)
• Current rating: 400 mA minimum
• Package classification: 0402 (1005 Metric) surface mount
• Core configuration: Drum core, wirewound, unshielded
• DC resistance: Must not exceed 360 mOhm maximum specification

Secondary Compatibility Parameters:

• Mounting type: Surface mount only
• Moisture sensitivity level: MSL 1 (Unlimited)
• Self-resonant frequency: Minimum 2.48 GHz

The substitute part LRW0402WG27NGG001T manufactured by Johanson Technology Inc. meets all primary substitution criteria with identical inductance, current rating, package type, and core configuration. The substitute exhibits lower DC resistance (298 mOhm maximum) and higher Q factor at 900 MHz, representing improved electrical performance within the same physical and functional envelope.

Engineering Selection Recommendations

S0402-27NG3C (API Delevan Inc.) is the primary component specification. This part maintains Active product status with unlimited inventory availability (1069 Pcs in stock). The component is RoHS non-compliant and carries EAR99 export classification.

LRW0402WG27NGG001T (Johanson Technology Inc.) qualifies as a direct substitute with the following considerations:

1. Electrical Performance: The substitute provides equivalent inductance and current rating specifications. DC resistance is 62 mOhm lower (298 mOhm vs. 360 mOhm maximum), representing improved performance margin. Q factor at 900 MHz is significantly higher (55 vs. 23 @ 250 MHz), indicating superior frequency response characteristics.

2. Thermal Operating Range: The substitute operates from -40°C to 125°C, compared to the primary part's -55°C to 125°C range. Applications requiring operation below -40°C must use the primary S0402-27NG3C component.

3. Compliance Status: The substitute is ROHS3 compliant, whereas the primary part is RoHS non-compliant. Applications subject to RoHS directives must specify the substitute part.

4. Physical Compatibility: Both components use identical 0402 (1005 Metric) surface mount packaging with compatible footprints. The substitute exhibits slightly smaller physical dimensions (1.00mm x 0.55mm vs. 1.09mm x 0.64mm) and lower seated height (0.60mm vs. 0.76mm), ensuring PCB layout compatibility.

5. Supply Chain: The substitute maintains significantly higher inventory availability (40,840 Pcs in stock vs. 1,069 Pcs), supporting extended production runs and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WG27NGG001T replace S0402-27NG3C in all applications?

A: The substitute is functionally equivalent for applications operating within -40°C to 125°C temperature range. Applications requiring operation below -40°C must use the primary S0402-27NG3C component due to its extended lower temperature specification of -55°C.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The substitute's 298 mOhm maximum DC resistance compared to 360 mOhm in the primary part represents a 17% reduction in resistive losses. This results in lower power dissipation and improved efficiency in high-current applications, while maintaining full compatibility with the 400 mA current rating.

Q: Are the physical dimensions interchangeable between these parts?

A: Both components conform to the 0402 (1005 Metric) package standard and are surface mount compatible. The substitute exhibits slightly smaller dimensions and lower profile, ensuring compatibility with existing PCB layouts designed for the primary part. No design modifications are required.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance status reflects manufacturing process and material composition standards but does not alter the electrical specifications of the inductor. The substitute's ROHS3 compliance and superior DC resistance characteristics make it suitable for applications subject to RoHS directives without performance compromise.

Q: What is the impact of different core materials on substitution?

A: The primary part uses alumina core material while the substitute uses ceramic core material. Both configurations maintain equivalent inductance, tolerance, and current rating specifications. The ceramic core in the substitute contributes to its superior Q factor performance at higher frequencies.

Q: Can these parts be used interchangeably in RF and microwave circuits?

A: Both components are specified for operation at frequencies up to their respective self-resonant frequencies (2.48 GHz and 2.5 GHz). The substitute's higher Q factor at 900 MHz indicates superior performance in RF applications within this frequency range. Circuit-specific validation is required for applications operating near self-resonant frequencies.
