Substitute Part Grouping Explanation

The LRW0402WG10NGG001T (Johanson Technology Inc.) qualifies as a direct substitute for the S0402-10NG2S based on the following critical parameters:

• Inductance Value: Both parts specify 10 nH with ±2% tolerance
• Package / Case: Both utilize 0402 (1005 Metric) surface mount configuration
• Core Type: Both are drum core, wirewound construction with unshielded configuration
• Frequency - Self Resonant: Both specified at 3.9 GHz
• Inductance Frequency - Test: Both tested at 250 MHz

Substitution compatibility is established through matching inductance specification, identical package form factor, equivalent core technology, and coincident resonant frequency characteristics. The substitute part maintains electrical compatibility within the defined parameter space.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status with sustained manufacturing support. The LRW0402WG10NGG001T offers the advantage of ROHS3 compliance, whereas the S0402-10NG2S is RoHS non-compliant. For applications requiring regulatory compliance with RoHS directives, the Johanson Technology substitute presents superior qualification standing.

The substitute part demonstrates lower DC resistance (195 mOhm vs. 210 mOhm maximum) and reduced physical height (0.024" seated height vs. 0.030"), providing potential benefits for thermal performance and high-density PCB layouts. Current rating specifications remain within acceptable operational margins (480 mA vs. 475 mA requirement).

Selection between these parts should prioritize regulatory requirements, board-level integration constraints, and thermal management considerations inherent to the application design.

Frequently Asked Questions (FAQ)

Can the LRW0402WG10NGG001T be used as a direct replacement for the S0402-10NG2S in existing PCB designs?

Yes. Both parts share identical inductance specification (10 nH ±2%), package form factor (0402 1005 Metric), and core technology (unshielded drum core wirewound). The substitute part demonstrates equivalent electrical characteristics at the specified test frequency of 250 MHz and maintains matching self-resonant frequency at 3.9 GHz. PCB footprints remain compatible without design modification.

What are the dimensional differences between these two inductors?

The LRW0402WG10NGG001T exhibits smaller maximum dimensions (0.039" x 0.022" vs. 0.043" x 0.025") and lower seated height (0.024" vs. 0.030"). These variations remain within the 0402 package specification envelope and pose no compatibility constraints for standard PCB assembly processes.

How do the DC resistance specifications compare, and what does this mean for circuit performance?

The S0402-10NG2S specifies 210 mOhm maximum DC resistance, while the substitute specifies 195 mOhm maximum. The lower resistance of the substitute part reduces parasitic losses and heat dissipation at equivalent current levels, providing marginal efficiency improvement in high-frequency applications.

Does the LRW0402WG10NGG001T meet RoHS compliance requirements?

The LRW0402WG10NGG001T is ROHS3 compliant. The S0402-10NG2S is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the Johanson Technology part fulfills compliance obligations.

Are there current rating differences that affect component selection?

The S0402-10NG2S supports 475 mA maximum current, while the LRW0402WG10NGG001T supports 480 mA. The substitute part exceeds the original specification by 5 mA, ensuring compatibility for designs operating at or below the original 475 mA maximum current threshold.
