Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSRN2010JK40L0 is determined by the following critical parameters:

• Resistance value: 40 mOhms (exact match required)
• Power rating: 1W (exact match required)
• Package type: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Feature classification: Current Sense (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Temperature coefficient: ±250ppm/°C (exact match required)

The CSRN2010FK40L0 qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±1% versus ±5%). This represents an upgrade path for applications requiring tighter tolerance control without any change to package, power rating, or thermal characteristics.
