Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805-82NJ is determined by the following critical parameters: inductance value (82 nH), tolerance specification (±5%), current rating capability (minimum 400 mA), DC resistance (maximum 420mOhm), unshielded configuration, and surface mount compatibility. The substitute parts listed maintain these core electrical characteristics while offering improved product status and compliance certifications.

Direct Substitutes (Bourns CW201212 Series):

• CW201212-82NJ and CW201212-82NG meet or exceed the electrical specifications of the original part with enhanced current ratings (500 mA) and lower DC resistance (320mOhm), providing superior performance margins.

Functional Equivalent (Murata LQW2BAS82NJ00L):

• LQW2BAS82NJ00L matches the original electrical specifications exactly, including current rating (400 mA) and DC resistance (420mOhm Max), with an air core design instead of ceramic core.

Parameter Comparison

Engineering Selection Recommendations

CW201212-82NJ (Bourns) is the primary recommended substitute. This part is active in production, ROHS3 compliant, and provides enhanced electrical performance with 500 mA current rating and 320mOhm DC resistance. The standard 0805 (2012 Metric) package ensures reliable PCB compatibility. Tape & Reel packaging supports automated assembly processes.

CW201212-82NG (Bourns) serves as an alternative with tighter tolerance specification (±2%) for applications requiring improved inductance accuracy. This variant maintains the same electrical performance advantages as the CW201212-82NJ.

LQW2BAS82NJ00L (Murata) is suitable for designs where the original electrical specifications must be matched exactly, including 400 mA current rating and 420mOhm DC resistance. This part offers extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. The air core design provides different electromagnetic characteristics compared to ceramic core alternatives.

All three substitutes are ROHS3 compliant and REACH unaffected, addressing regulatory requirements that the obsolete original part does not meet.

Frequently Asked Questions (FAQ)

Q: Can CW201212-82NJ be used as a direct replacement for 0805-82NJ? A: Yes. The CW201212-82NJ maintains the same 82 nH inductance, ±5% tolerance, and unshielded configuration. The higher current rating (500 mA vs. 400 mA) and lower DC resistance (320mOhm vs. 420mOhm) provide improved performance margins. The standard 0805 (2012 Metric) package is mechanically compatible with the original nonstandard 0805 form factor.

Q: What is the difference between CW201212-82NJ and CW201212-82NG? A: Both parts are electrically identical with 82 nH inductance, 500 mA current rating, and 320mOhm DC resistance. The primary difference is tolerance: CW201212-82NJ offers ±5% tolerance, while CW201212-82NG provides tighter ±2% tolerance. Select CW201212-82NG for applications requiring improved inductance accuracy.

Q: Why is LQW2BAS82NJ00L listed as a functional equivalent rather than a direct substitute? A: LQW2BAS82NJ00L uses an air core design instead of ceramic core, resulting in different electromagnetic characteristics. While it matches the original part's inductance (82 nH), current rating (400 mA), and DC resistance (420mOhm Max), the core material difference may affect performance in specific circuit applications. This part is suitable for designs where the original specifications must be preserved exactly.

Q: Are all substitute parts RoHS compliant? A: Yes. CW201212-82NJ, CW201212-82NG, and LQW2BAS82NJ00L are all ROHS3 compliant. The original 0805-82NJ is RoHS non-compliant, making these substitutes necessary for designs subject to RoHS regulations.

Q: What is the package difference between the original and substitute parts? A: The original 0805-82NJ uses a nonstandard 0805 package. Bourns substitutes (CW201212 series) use the standard 0805 (2012 Metric) package. Murata's LQW2BAS82NJ00L uses 0805 (2015 Metric) package. All three are mechanically compatible with standard 0805 PCB footprints, though minor dimensional variations exist within the 0805 specification range.

Q: Can these parts be used interchangeably in existing designs? A: CW201212-82NJ and CW201212-82NG are fully interchangeable with the original part for most applications due to matching inductance, tolerance, and unshielded configuration. LQW2BAS82NJ00L is interchangeable for applications where the air core design does not introduce unacceptable performance variations. Verify circuit performance requirements before final selection.
