Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S0603-82NJ2C are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 82 nH ±5% tolerance
• Current rating: 400 mA minimum
• DC resistance: Within acceptable range for the application (570 mOhm maximum for main part; 540 mOhm for substitutes represents improved performance)
• Self-resonant frequency: 1.7 GHz
• Q factor: Approximately 34-35 @ 150 MHz

Mechanical Compatibility Criteria:

• Package classification: 0603 (1608 Metric) surface mount
• Unshielded configuration
• Physical dimensions compatible with 0603 footprint
• Moisture sensitivity level: 1 (Unlimited)

Compliance Criteria:

• RoHS status: Active substitutes are ROHS3 compliant
• REACH status: REACH Unaffected
• ECCN classification: EAR99

All identified substitutes maintain electrical performance within the specified tolerance band and are mechanically compatible with the original part's footprint and mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Preferred):

The LRW0603WJ82NGG001E (Johanson Technology Inc.) and PM0603-82NJ-RC (Bourns Inc.) are the primary substitute options. Both parts are ROHS3 compliant, addressing regulatory requirements where the original S0603-82NJ2C does not meet RoHS standards. Both maintain identical electrical specifications (82 nH ±5%, 400 mA, 540 mOhm DCR) and are qualified for the 0603 surface mount package. The LRW0603WJ82NGG001E offers the highest inventory availability (83,700 pcs) and operates across the -40°C to 125°C temperature range. The PM0603-82NJ-RC provides equivalent performance with alumina core material matching the original part's core construction.

Secondary Substitute:

The LQW18AS82NJ00D (Murata Electronics) is a qualified substitute with ROHS3 compliance and identical electrical parameters. This part features a non-magnetic core construction and operates within the -40°C to 125°C temperature range. All three substitute parts maintain the critical electrical performance metrics and mechanical compatibility required for direct replacement in 0603 footprint applications.

Temperature Consideration:

Applications requiring operation below -40°C must retain the original S0603-82NJ2C, as all substitute parts are rated to -40°C minimum. For applications within the -40°C to 125°C range, substitutes provide equivalent or improved performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LQW18AS82NJ00D replace the S0603-82NJ2C in all applications?

A: The LQW18AS82NJ00D is electrically equivalent for inductance (82 nH ±5%), current rating (400 mA), and DC resistance (540 mOhm). Both parts are unshielded, surface mount, 0603 package components with identical self-resonant frequency (1.7 GHz) and Q factor (34 @ 150 MHz). The primary difference is the operating temperature range: the substitute operates from -40°C to 125°C, while the original operates from -55°C to 125°C. Substitution is valid for applications within the -40°C to 125°C range.

Q: What is the significance of the DC resistance difference between 570 mOhm and 540 mOhm?

A: The substitute parts feature lower maximum DC resistance (540 mOhm) compared to the original part (570 mOhm). Lower DC resistance represents improved electrical performance, reducing resistive losses in the inductor. This difference is within typical manufacturing tolerances for this component class and does not affect functional compatibility. Applications designed for the 570 mOhm specification will operate with improved efficiency using the 540 mOhm substitutes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The LQW18AS82NJ00D, LRW0603WJ82NGG001E, and PM0603-82NJ-RC are all ROHS3 compliant. The original S0603-82NJ2C is RoHS non-compliant. For applications requiring RoHS compliance, any of the three substitute parts are suitable replacements.

Q: Do the substitute parts fit the same PCB footprint as the S0603-82NJ2C?

A: All substitute parts are qualified for the 0603 (1608 Metric) surface mount package. Physical dimensions vary slightly between manufacturers (length ranges from 1.58 mm to 1.65 mm, width ranges from 0.80 mm to 1.05 mm, height ranges from 0.99 mm to 1.25 mm), but all dimensions remain within the 0603 package specification envelope. PCB footprints designed for 0603 components accommodate all substitute parts.

Q: What is the difference between drum core and non-magnetic core construction?

A: The S0603-82NJ2C and PM0603-82NJ-RC feature drum core construction with alumina material. The LQW18AS82NJ00D features non-magnetic core construction. The LRW0603WJ82NGG001E features drum core construction with ceramic material. All three core types deliver the specified 82 nH inductance and electrical performance. Core material selection affects frequency response characteristics and thermal properties but does not impact the fundamental electrical equivalence for this inductance value and current rating.

Q: Which substitute part offers the best inventory availability?

A: The LRW0603WJ82NGG001E (Johanson Technology Inc.) offers the highest inventory availability with 83,700 pcs in stock, compared to 1,315 pcs for the Murata part and 3,727 pcs for the Bourns part.
