Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW201212-10NJ is determined by strict alignment of the following electrical and mechanical parameters:

Inductance value must be 10 nH with ±5% tolerance. Current rating must support minimum 600 mA continuous operation. DC resistance must not exceed 80 mOhm maximum. Package configuration must be 0805 (2012 Metric) for PCB footprint compatibility. Core material must be ceramic with unshielded construction. Q factor at 500 MHz must be 60 or greater. Self resonant frequency must be 4.8 GHz. Operating temperature range must encompass the application requirements. RoHS3 compliance is mandatory for regulatory alignment.

The substitute part IMC0805ER10NJ01 from Vishay Dale meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CW201212-10NJ and IMC0805ER10NJ01 are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain availability, lead time requirements, and inventory positioning. The CW201212-10NJ supports operation to 125°C maximum, while the IMC0805ER10NJ01 is rated to 105°C maximum. Applications requiring sustained operation above 105°C must use the CW201212-10NJ. For applications within the 105°C limit, either part provides equivalent electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can IMC0805ER10NJ01 be used as a direct replacement for CW201212-10NJ?

A: Yes, for applications operating at or below 105°C. Both parts share identical inductance (10 nH), tolerance (±5%), current rating (600 mA), DC resistance (80 mOhm maximum), package (0805 2012 Metric), and Q factor (60 @ 500MHz). The primary difference is the maximum operating temperature: CW201212-10NJ extends to 125°C while IMC0805ER10NJ01 is limited to 105°C.

Q: Are the physical dimensions compatible for PCB assembly?

A: The parts differ slightly in seated height and overall dimensions. CW201212-10NJ measures 0.083" L × 0.059" W with 0.059" maximum seated height. IMC0805ER10NJ01 measures 0.079" L × 0.049" W with 0.055" maximum seated height. Both conform to the 0805 (2012 Metric) package standard and are compatible with standard 0805 PCB footprints.

Q: What compliance certifications apply to both parts?

A: Both parts carry RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: How do the saturation current specifications compare?

A: The CW201212-10NJ specifies saturation current (Isat) at 1.02A. The IMC0805ER10NJ01 does not provide a saturation current specification in the available data. For applications where saturation current is a critical design parameter, the CW201212-10NJ provides explicit specification.
