Substitute Part Grouping Explanation

Substitution eligibility for the 0805-47NJ is determined by the following critical parameters: inductance value (47 nH), inductance tolerance (±5%), current rating (500 mA), DC resistance (310mOhm maximum), operating temperature range (-40°C to 125°C), and surface mount package compatibility (0805 form factor).

The substitute parts are grouped into two categories:

Direct Substitutes (Bourns CW201212 Series): CW201212-47NG and CW201212-47NJ maintain the same inductance, current rating, and operating temperature range. Both are active products with improved DC resistance specifications (150mOhm versus 310mOhm maximum) and RoHS3 compliance. CW201212-47NJ matches the ±5% tolerance of the original part, while CW201212-47NG offers tighter ±2% tolerance.

Equivalent Substitute (Murata LQW2BAS47NJ00L): The Murata part matches the original inductance, current rating, DC resistance (310mOhm maximum), and tolerance (±5%). It differs in core material (air core versus ceramic) and temperature range extension (-55°C to 125°C). This part is an active product with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 0805-47NJ, the Bourns CW201212-47NJ is the primary substitute. It maintains identical electrical specifications (47 nH, ±5% tolerance, 500 mA, -40°C to 125°C) while offering improved DC resistance (150mOhm versus 310mOhm maximum) and active product status with ROHS3 compliance. The standard 0805 (2012 Metric) package ensures compatibility with existing PCB layouts.

The Bourns CW201212-47NG provides an alternative with tighter inductance tolerance (±2%) and identical performance characteristics, suitable for applications requiring higher precision.

The Murata LQW2BAS47NJ00L is suitable for applications requiring extended low-temperature operation (-55°C minimum). It maintains the original DC resistance specification (310mOhm maximum) and ±5% tolerance. The air core construction differs from the ceramic core of the original part but delivers equivalent electrical performance at the specified operating frequencies. This part is available in active status with ROHS3 compliance.

All three substitute parts are RoHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet.

Frequently Asked Questions (FAQ)

Q: Can the Bourns CW201212-47NJ be used as a direct replacement for the API Delevan 0805-47NJ?

A: Yes. Both parts share identical inductance (47 nH), tolerance (±5%), current rating (500 mA), operating temperature range (-40°C to 125°C), and surface mount package form factor. The Bourns part offers improved DC resistance (150mOhm versus 310mOhm maximum) and is an active product with ROHS3 compliance.

Q: What is the difference between the Bourns CW201212-47NJ and CW201212-47NG?

A: Both parts are electrically equivalent with identical inductance (47 nH), current rating (500 mA), and DC resistance (150mOhm). The primary difference is inductance tolerance: CW201212-47NJ offers ±5% tolerance, while CW201212-47NG provides tighter ±2% tolerance. Select CW201212-47NG for applications requiring higher inductance precision.

Q: Why does the Murata LQW2BAS47NJ00L have a different core material?

A: The Murata part uses an air core construction instead of ceramic. Both core types deliver the same inductance value (47 nH), Q factor (60 @ 500MHz), and self-resonant frequency (1.7GHz) at the specified operating conditions. Core material selection does not affect substitution eligibility when electrical parameters remain equivalent.

Q: Is the Murata LQW2BAS47NJ00L suitable for low-temperature applications?

A: Yes. The Murata part operates from -55°C to 125°C, extending the minimum operating temperature by 15°C compared to the original part (-40°C to 125°C). This makes it suitable for applications requiring enhanced low-temperature performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both Bourns CW201212 variants and the Murata LQW2BAS47NJ00L are ROHS3 compliant. The original API Delevan 0805-47NJ is RoHS non-compliant, making these substitutes necessary for applications subject to RoHS regulations.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All substitute parts are surface mount 0805 form factor inductors with compatible physical dimensions and mounting requirements. Verify specific PCB layout dimensions with component datasheets if required.
