• DC resistance: Must not exceed 360 mOhm maximum
• Frequency characteristics: Self-resonant frequency and Q factor at specified test frequency

Mechanical Parameters:

• Package classification: 0402 (1005 Metric) surface mount
• Physical dimensions: Compatible with 0402 footprint requirements
• Height seated maximum: Must fit within PCB assembly constraints

Environmental Parameters:

• Operating temperature range: Minimum -55°C to 125°C coverage
• Moisture sensitivity level: MSL 1 (Unlimited)

Compliance Parameters:

• REACH status: REACH Unaffected
• ECCN classification: EAR99

The substitute part LRW0402WG27NGG001T meets all critical substitution criteria across electrical, mechanical, and environmental specifications.

Engineering Selection Recommendations

Primary Part: S0402-27NG2C

The S0402-27NG2C maintains active product status with established inventory availability (868 pieces). This part is suitable for applications requiring the full operating temperature range of -55°C to 125°C. RoHS non-compliance status must be evaluated against specific application requirements and regional regulations.

Substitute Part: LRW0402WG27NGG001T

The LRW0402WG27NGG001T from Johanson Technology Inc. provides equivalent electrical performance with the following distinctions:

• DC Resistance Advantage: 298 mOhm maximum versus 360 mOhm, representing improved efficiency characteristics
• Physical Dimensions: Smaller footprint (1.00mm x 0.55mm versus 1.09mm x 0.64mm) with reduced seated height (0.60mm versus 0.76mm)
• RoHS Compliance: ROHS3 compliant status addresses regulatory requirements where applicable
• Temperature Range Limitation: Operating range of -40°C to 125°C restricts use in applications requiring -55°C minimum operation
• Packaging: Supplied in Cut Tape format with significantly higher inventory availability (40,840 pieces)

Selection between these parts depends on application-specific requirements: temperature range necessity, regulatory compliance mandates, and physical space constraints on the PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WG27NGG001T replace S0402-27NG2C in all applications?

A: Substitution is valid for applications operating within the -40°C to 125°C temperature range. Applications requiring -55°C minimum operation must use the S0402-27NG2C. All other electrical and mechanical parameters are compatible.

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

A: The LRW0402WG27NGG001T exhibits 298 mOhm maximum DC resistance compared to 360 mOhm in the S0402-27NG2C. Lower DC resistance reduces resistive losses and heat generation in the inductor, improving circuit efficiency. Both values remain within acceptable ranges for 27 nH inductors at 400 mA operation.

Q: Are the physical dimensions interchangeable?

A: Both parts use the 0402 (1005 Metric) package classification and are mechanically compatible with standard 0402 PCB footprints. The LRW0402WG27NGG001T has slightly smaller dimensions (1.00mm x 0.55mm versus 1.09mm x 0.64mm) and lower seated height (0.60mm versus 0.76mm), which may provide advantages in space-constrained designs without requiring footprint modification.

Q: What packaging formats are available?

A: The S0402-27NG2C is supplied in standard packaging format. The LRW0402WG27NGG001T is available in Cut Tape (CT) format, which is standard for high-volume automated assembly operations.

Q: How do the Q factor specifications differ?

A: The S0402-27NG2C specifies Q of 23 at 250 MHz. The LRW0402WG27NGG001T specifies Q of 55 at 900 MHz. These measurements occur at different frequencies and reflect the different core materials (Alumina versus Ceramic). Both values are appropriate for their respective designs at the specified test frequencies.

Q: What is the difference in self-resonant frequency?

A: The S0402-27NG2C has a self-resonant frequency of 2.48 GHz, while the LRW0402WG27NGG001T is rated at 2.5 GHz. Both values are within typical ranges for 27 nH inductors and do not affect substitution eligibility for standard RF and high-frequency applications.

Q: Are there RoHS compliance considerations?

A: The S0402-27NG2C is RoHS non-compliant. The LRW0402WG27NGG001T is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements must use the compliant substitute part.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply without special moisture control requirements.
