Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the S0402-10NG3C is determined by the following critical parameters:

• Inductance Value & Tolerance: Substitute must provide 10 nH ±2% to maintain circuit performance
• Current Rating: Minimum 475 mA required to support application current demands
• DC Resistance: Maximum 210 mOhm to ensure acceptable power dissipation and circuit behavior
• Package Compatibility: 0402 (1005 Metric) surface mount package required for physical and electrical PCB placement
• Shielding Configuration: Unshielded design must be maintained to match electromagnetic performance characteristics
• Core Material & Type: Drum core wirewound construction with compatible core material properties
• Operating Temperature Range: Must support the required thermal environment

The substitute part LRW0402WG10NGG001T by Johanson Technology Inc. satisfies these substitution criteria within the scope of allowed electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both components meet the fundamental electrical and mechanical substitution criteria for 10 nH inductance in the 0402 surface mount package. The LRW0402WG10NGG001T provides equivalent inductance tolerance, superior current capability (480 mA vs. 475 mA), and improved DC resistance characteristics (195 mOhm vs. 210 mOhm), delivering reduced power dissipation.

The LRW0402WG10NGG001T is ROHS3 compliant, whereas the S0402-10NG3C is non-compliant, which may be significant for applications subject to regulatory or procurement requirements. The S0402-10NG3C supports a lower operating temperature limit of -55°C compared to -40°C for the substitute, making the original component necessary for cryogenic or extended temperature-range applications.

Physical dimensions differ slightly: the original component measures 0.043" L x 0.025" W with 0.030" maximum seated height, while the substitute measures 0.039" L x 0.022" W with 0.024" maximum seated height. Both maintain compatibility with standard 0402 PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can the LRW0402WG10NGG001T directly replace the S0402-10NG3C in my circuit?

A: Yes, for applications operating within the -40°C to 125°C temperature range. Both components deliver 10 nH inductance at ±2% tolerance with equivalent unshielded drum core construction and 0402 surface mount packaging. The substitute provides improved DC resistance and current ratings, making it electrically compatible within the specified operating parameters.

Q: What is the impact of core material differences on circuit performance?

A: The original component uses alumina core material while the substitute uses ceramic core material. Both materials are suitable for drum core wirewound inductors at these specifications. Core material selection affects frequency response and Q-factor characteristics, but both components are tested at 250 MHz inductance frequency and deliver equivalent inductance values across the operating frequency range.

Q: Does the smaller physical size of the LRW0402WG10NGG001T affect PCB layout compatibility?

A: No. Both components use the 0402 (1005 Metric) package standard, which defines the electrical footprint. Physical dimension variations within this package specification remain compatible with standard 0402 PCB footprints and assembly processes. Layout and placement procedures remain unchanged.

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

A: The LRW0402WG10NGG001T is ROHS3 compliant while the S0402-10NG3C is non-compliant. Applications subject to ROHS3 regulatory requirements must use the compliant substitute. Applications without regulatory constraints may use either component.

Q: Are there any temperature range limitations when using the substitute?

A: The LRW0402WG10NGG001T operates from -40°C to 125°C, compared to -55°C to 125°C for the original. Use the original S0402-10NG3C for applications requiring operation below -40°C. For standard industrial and commercial applications operating at or above -40°C, the substitute provides equivalent thermal performance.
