Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0805-68NJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 68 nH
• Inductance tolerance: ±5%
• Current rating: 500 mA minimum
• Core material: Ceramic
• Core type: Drum core, wirewound
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 125°C minimum
• Self resonant frequency: 1.45 GHz
• Q factor @ 500 MHz: 60

Allowable Variation:

• DC resistance (DCR): Substitute parts may have lower DCR values than the 380 mOhm maximum specification of the original part, provided all other parameters remain equivalent.
• Package configuration: Physical dimensions may vary within the 0805 (2012 Metric) standard footprint classification.
• Product status: Active parts are preferred over obsolete classifications for procurement continuity.

The Bourns Inc. CW201212-68NJ meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Bourns Inc. CW201212-68NJ is the qualified substitute for the obsolete API Delevan Inc. 0805-68NJ based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match the original specification, including inductance value, tolerance, current rating, Q factor, and self resonant frequency. The DC resistance of the substitute part (270 mOhm) is lower than the maximum specification (380 mOhm), which represents an improvement in performance characteristics.

Product Status: The CW201212-68NJ is classified as active, ensuring long-term availability and procurement continuity. The original 0805-68NJ is obsolete and subject to supply discontinuation.

Compliance Status: The CW201212-68NJ is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component procurement.

Physical Compatibility: Both parts are surface mount devices with comparable physical dimensions. The CW201212-68NJ is packaged in the standardized 0805 (2012 Metric) format, whereas the original uses a nonstandard package. Physical footprint differences are minimal and within typical PCB layout tolerances for this component class.

Packaging and Availability: The CW201212-68NJ is supplied in Tape & Reel (TR) format with confirmed inventory of 11,164 pieces, supporting production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the CW201212-68NJ be used as a direct replacement for the 0805-68NJ in existing designs?

A: Yes. The CW201212-68NJ meets all mandatory electrical specifications for the 0805-68NJ, including inductance value, tolerance, current rating, Q factor, and operating temperature range. Physical dimensions are comparable within standard surface mount tolerances.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The CW201212-68NJ has a DC resistance of 270 mOhm compared to the 380 mOhm maximum of the original part. Lower DC resistance reduces power dissipation and heat generation in the inductor, representing an improvement over the original specification.

Q: Are there any package compatibility concerns?

A: The original 0805-68NJ uses a nonstandard package, while the CW201212-68NJ uses the standardized 0805 (2012 Metric) format. Physical dimensions differ slightly (0.090" x 0.068" versus 0.083" x 0.059"), but both are surface mount devices with compatible mounting characteristics. PCB layout verification is recommended for designs with tight spatial constraints.

Q: What is the impact of the RoHS compliance difference?

A: The original 0805-68NJ is RoHS non-compliant, while the CW201212-68NJ is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute part provides regulatory alignment. For legacy systems without RoHS mandates, both parts are functionally equivalent.

Q: Is the MSL rating the same for both parts?

A: Yes. Both the 0805-68NJ and CW201212-68NJ are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the basis for substitution compatibility?

A: Substitution is based on strict electrical parameter equivalence: identical inductance (68 nH), tolerance (±5%), current rating (500 mA), core type (ceramic drum core, wirewound), shielding (unshielded), Q factor (60 @ 500 MHz), self resonant frequency (1.45 GHz), and operating temperature range (-40°C to 125°C). The lower DC resistance of the substitute represents an allowable variation that improves performance.
