Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM0805-82NK-RC is determined by the following critical parameters:

• Inductance value of 82 nH within specified tolerance
• Current rating of 500 mA minimum
• DC resistance of 320mOhm
• 0805 (2012 Metric) package footprint and form factor
• Surface mount configuration
• Operating temperature range of -40°C to 125°C
• Unshielded drum core wirewound construction

The substitute part CW201212-82NJ meets all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Bourns Inc., share identical inductance, current rating, DC resistance, package dimensions, and operating temperature specifications. The primary difference is the core material composition and inductance tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

Both PM0805-82NK-RC and CW201212-82NJ are active production components from Bourns Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on tolerance requirements and core material specifications. The PM0805-82NK-RC features an alumina core with ±10% inductance tolerance, while the CW201212-82NJ uses a ceramic core with tighter ±5% inductance tolerance. Both parts maintain identical electrical performance characteristics including 82 nH inductance, 500 mA current rating, 320mOhm DC resistance, and 1.35GHz self-resonant frequency. Applications requiring tighter inductance tolerance specifications should specify CW201212-82NJ. Both parts are suitable for surface mount assembly in 0805 package footprints with unlimited moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can CW201212-82NJ replace PM0805-82NK-RC in existing designs?

A: Yes. Both parts share identical inductance value, current rating, DC resistance, package dimensions, and operating temperature range. The CW201212-82NJ offers tighter inductance tolerance (±5% versus ±10%), making it suitable for applications where the PM0805-82NK-RC is specified.

Q: What is the difference between the core materials?

A: PM0805-82NK-RC uses an alumina core while CW201212-82NJ uses a ceramic core. Both are unshielded drum core wirewound constructions with identical electrical performance at the specified frequency range.

Q: Are the package dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) with dimensions of 0.083" L x 0.059" W (2.10mm x 1.50mm) and maximum seated height of 0.059" (1.50mm). They are mechanically interchangeable in surface mount applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PM0805-82NK-RC and CW201212-82NJ are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited) for moisture sensitivity.

Q: What is the inductance tolerance difference?

A: PM0805-82NK-RC has ±10% inductance tolerance while CW201212-82NJ has ±5% tolerance. Applications requiring tighter inductance specifications should use CW201212-82NJ.
