S0603-82NJ3C Equivalent & Substitute Parts

Part Overview

The S0603-82NJ3C is a fixed unshielded drum core, wirewound inductor manufactured by API Delevan Inc. with a nominal inductance of 82 nH, rated for 400 mA continuous current, and a maximum DC resistance of 570 mOhm. This component is designed for surface mount applications in the 0603 (1608 Metric) package. The part is currently in active production status. Alternative equivalent parts are identified when design requirements necessitate different compliance certifications, improved electrical characteristics, alternative core materials, or enhanced inventory availability without compromising electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the S0603-82NJ3C is determined by strict compliance with the following critical electrical and mechanical parameters:

• Inductance Value: 82 nH ±5%
• Current Rating: 400 mA minimum
• DC Resistance: 540 mOhm to 570 mOhm maximum (lower resistance is acceptable)
• Package / Case: 0603 (1608 Metric) surface mount
• Frequency Performance: Self-resonant frequency at or above 1.7 GHz
• Operating Temperature Range: Support for -40°C to 125°C minimum

All listed substitute parts meet these core electrical specifications. Variations in core material composition (Alumina, Non-Magnetic, or Ceramic) and manufacturer-specific Q-factor measurements do not prevent functional equivalence provided inductance, current rating, and DC resistance remain within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

S0603-82NJ3C (API Delevan Inc.): Suitable for applications not requiring ROHS3 compliance. Supports the extended low-temperature operating range to -55°C. Higher DC resistance (570 mOhm maximum) results in increased power dissipation compared to alternatives.

LQW18AS82NJ00D (Murata Electronics): ROHS3-compliant alternative with 540 mOhm maximum DC resistance. Non-magnetic core material construction. Inductance frequency test specification of 100 MHz differs from the reference part's 150 MHz specification. Highest inventory availability (1315 pieces).

LRW0603WJ82NGG001E (Johanson Technology Inc.): ROHS3-compliant drum core inductor with ceramic core material. Maximum DC resistance of 540 mOhm. Q-factor of 35 at 150 MHz represents the highest quality factor among listed options. Inductance frequency test at 250 MHz. Largest available inventory (83,700 pieces).

PM0603-82NJ-RC (Bourns Inc.): ROHS3-compliant drum core inductor with alumina core material matching the reference part's core composition. Maximum DC resistance of 540 mOhm. Q-factor measured at 250 MHz. All dimensional specifications remain compatible with standard 0603 surface mount footprints.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts for the S0603-82NJ3C without circuit redesign?

A: Yes, provided your application does not require the S0603-82NJ3C's extended operating temperature range below -40°C or non-compliant RoHS status. All substitute parts maintain equivalent inductance (82 nH ±5%), current rating (400 mA), and package footprint (0603 metric).

Q: What is the impact of different DC resistance values on my circuit?

A: The S0603-82NJ3C specifies 570 mOhm maximum DC resistance, while substitute parts specify 540 mOhm maximum. Lower DC resistance produces less resistive power dissipation at equivalent current levels. For 400 mA operation, the S0603-82NJ3C dissipates up to 91.2 mW, while alternatives dissipate up to 86.4 mW. Circuit performance differences depend on whether your design accounts for this dissipation specification.

Q: Do the different core materials affect circuit performance?

A: Core material differences (Alumina, Non-Magnetic, or Ceramic) do not alter the specified electrical parameters of inductance, current rating, or DC resistance. All parts meet the same frequency performance specification (1.7 GHz self-resonant frequency). Material selection may influence cost, manufacturing process consistency, and availability, but electrical equivalence is maintained.

Q: Which substitute part should I select for maximum inventory availability?

A: LRW0603WJ82NGG001E (Johanson Technology) maintains the highest inventory level at 83,700 pieces. This part combines ROHS3 compliance, the highest quality factor (35 @ 150MHz), and 540 mOhm DC resistance.

Q: Are there temperature range differences I should consider?

A: The S0603-82NJ3C operates from -55°C to 125°C. All substitute parts operate from -40°C to 125°C. Select the original S0603-82NJ3C only if your circuit requires operation below -40°C. Otherwise, substitute parts are compatible.

Q: What compliance certifications differ between these parts?

A: The S0603-82NJ3C is RoHS non-compliant. All substitute parts (LQW18AS82NJ00D, LRW0603WJ82NGG001E, PM0603-82NJ-RC) are ROHS3 compliant. Select a substitute part if your application or procurement requirements mandate RoHS compliance.
