Substitute Part Grouping Explanation

Substitution eligibility for the S0402-10NG1S is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 nH (exact match required)
• Tolerance: ±2% (exact match required)
• Package form factor: 0402 (1005 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Shielding configuration: Unshielded (exact match required)

Secondary Compatibility Parameters:

• Current rating: minimum 475 mA
• DC resistance: maximum 210 mOhm
• Operating temperature range: must encompass or equal -55°C to 125°C
• Component type: Drum Core, Wirewound (exact match required)

The substitute part LRW0402WG10NGG001T meets all primary matching criteria and demonstrates compatible secondary parameters, qualifying it as a direct electrical and mechanical substitute.

Engineering Selection Recommendations

S0402-10NG1S (API Delevan Inc.):

• Product Status: Active
• RoHS Status: Non-compliant
• REACH Status: Unaffected
• Packaging: Bulk
• Inventory: 827 pieces available
• Operating Temperature: -55°C to 125°C (extended lower limit)

LRW0402WG10NGG001T (Johanson Technology Inc.):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: Unaffected
• Packaging: Cut Tape (CT)
• Inventory: 35,881 pieces available
• Operating Temperature: -40°C to 125°C

Selection between these parts depends on application-specific requirements. The S0402-10NG1S provides extended low-temperature operation to -55°C and is available in bulk packaging. The LRW0402WG10NGG001T offers ROHS3 compliance, lower DC resistance (195 mOhm vs. 210 mOhm), higher current rating (480 mA vs. 475 mA), and greater inventory availability in cut tape format. Both parts share identical inductance, tolerance, package dimensions, and self-resonant frequency characteristics.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WG10NGG001T replace S0402-10NG1S in all applications?

A: LRW0402WG10NGG001T is electrically and mechanically compatible for applications operating at temperatures above -40°C. Applications requiring operation below -40°C must use S0402-10NG1S, as the substitute part is rated only to -40°C minimum.

Q: What are the physical differences between these parts?

A: Both parts conform to the 0402 (1005 Metric) package standard. LRW0402WG10NGG001T has slightly smaller dimensions (1.00mm x 0.55mm vs. 1.09mm x 0.64mm) and lower seated height (0.60mm vs. 0.76mm), making it suitable for space-constrained layouts while maintaining full electrical compatibility.

Q: How do the DC resistance values affect circuit performance?

A: LRW0402WG10NGG001T exhibits lower maximum DC resistance (195 mOhm vs. 210 mOhm), resulting in reduced resistive losses. Both values fall within acceptable ranges for 10 nH inductors in this package class. Selection should be based on specific circuit impedance and loss requirements.

Q: Are there packaging format considerations for procurement?

A: S0402-10NG1S is supplied in bulk packaging, while LRW0402WG10NGG001T is supplied in cut tape format. Bulk packaging is suitable for high-volume manufacturing; cut tape format accommodates automated pick-and-place equipment. Procurement strategy should align with assembly process requirements.

Q: What is the significance of the Q factor difference?

A: S0402-10NG1S specifies Q of 20 at 250 MHz; LRW0402WG10NGG001T specifies Q of 56 at 900 MHz. These measurements occur at different frequencies and reflect core material differences (alumina vs. ceramic). Both values are appropriate for their respective designs and do not preclude substitution at 250 MHz operation.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical substitution criterion. S0402-10NG1S is RoHS non-compliant; LRW0402WG10NGG001T is ROHS3 compliant. Selection depends on end-product regulatory requirements and customer specifications.
