S0603-82NJ2D Equivalent & Substitute Parts Reference

Part Overview

The S0603-82NJ2D is a 82 nH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications in the 0603 (1608 Metric) package. This component operates at 400 mA current rating with a maximum DC resistance of 570 mOhm and is classified as Active product status. The part is RoHS non-compliant and carries Moisture Sensitivity Level 1 (Unlimited).

Equivalent and substitute parts are identified when components share identical or functionally compatible electrical and mechanical specifications within the allowed parameter tolerances for this inductor category. Substitutes enable design flexibility, supply chain continuity, and alternative sourcing options while maintaining circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S0603-82NJ2D is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Inductance value: 82 nH with ±5% tolerance
• Current rating: 400 mA minimum
• Package / Case: 0603 (1608 Metric) surface mount
• Shielding configuration: Unshielded
• Self-resonant frequency: 1.7 GHz
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• DC Resistance (DCR): Substitute parts with DCR ≤ 570 mOhm are functionally compatible
• Operating temperature range: Substitute parts with operating range ≥ -40°C ~ 125°C are acceptable
• Core material: Alumina, Non-Magnetic, or Ceramic core materials are interchangeable for this application
• Inductor type: Drum core wirewound and wirewound configurations are equivalent

All three substitute parts meet these criteria and are classified as direct equivalents for the S0603-82NJ2D.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as Active product status and maintain electrical and mechanical compatibility with the S0603-82NJ2D across critical parameters including inductance, current rating, package dimensions, and self-resonant frequency.

Compliance Considerations:

The S0603-82NJ2D is RoHS non-compliant. If RoHS3 compliance is required for the application, all three substitute parts (LQW18AS82NJ00D, LRW0603WJ82NGG001E, and PM0603-82NJ-RC) are ROHS3 compliant alternatives.

Temperature Range:

The S0603-82NJ2D operates across -55°C ~ 125°C. Substitute parts operate across -40°C ~ 125°C. Applications requiring operation below -40°C must retain the S0603-82NJ2D.

DC Resistance:

The S0603-82NJ2D specifies 570 mOhm maximum DCR. All substitute parts feature 540 mOhm maximum DCR, representing a 30 mOhm improvement in resistance characteristics.

Inventory Availability:

LRW0603WJ82NGG001E (Johanson Technology) offers the highest inventory availability at 83,700 pieces. LQW18AS82NJ00D (Murata) provides 1,315 pieces, and PM0603-82NJ-RC (Bourns) provides 3,727 pieces.

Frequently Asked Questions (FAQ)

Q: Can LQW18AS82NJ00D replace S0603-82NJ2D in all applications?

A: LQW18AS82NJ00D is electrically and mechanically compatible with S0603-82NJ2D for applications operating within -40°C ~ 125°C. The substitute features identical inductance (82 nH ±5%), current rating (400 mA), package (0603), and self-resonant frequency (1.7 GHz). Applications requiring operation below -40°C must use the S0603-82NJ2D.

Q: What is the difference in DC resistance between the main part and substitutes?

A: The S0603-82NJ2D specifies 570 mOhm maximum DCR. All three substitute parts specify 540 mOhm maximum DCR, representing a 30 mOhm lower resistance. This difference is within acceptable tolerances for equivalent component selection and may provide marginal performance improvement in low-impedance circuit paths.

Q: Are the substitute parts available in the same packaging format?

A: All substitute parts are available in Tape & Reel (TR) packaging. The S0603-82NJ2D packaging format is not specified in the provided data. Confirm packaging requirements with your procurement specification before finalizing substitution.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance does not affect electrical or mechanical substitution eligibility. The S0603-82NJ2D is RoHS non-compliant, while all three substitutes are ROHS3 compliant. If your application or supply chain requires RoHS3 compliance, any of the three substitute parts are suitable alternatives.

Q: Which substitute part offers the best inventory availability?

A: LRW0603WJ82NGG001E (Johanson Technology Inc.) offers 83,700 pieces in stock, significantly exceeding availability of other substitutes. PM0603-82NJ-RC (Bourns) provides 3,727 pieces, and LQW18AS82NJ00D (Murata) provides 1,315 pieces.

Q: Are there dimensional differences between the main part and substitutes?

A: Minor dimensional variations exist within the 0603 (1608 Metric) package specification. The S0603-82NJ2D measures 0.062" L x 0.035" W x 0.040" H (max). Substitute parts range from 0.063" L x 0.031" W x 0.039" H (Murata) to 0.065" L x 0.041" W x 0.047" H (Bourns). All dimensions remain within standard 0603 package tolerances and are compatible with standard PCB footprints.
