Substitute Part Grouping Explanation

Substitution eligibility for the CSS2H-3920R-L300FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 0.3 mOhms
• Tolerance: ±1%
• Power rating: 10W
• Package type: 3920 (1052 Metric)
• Composition: Metal Element
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive qualification: AEC-Q200
• Physical dimensions: 0.394" L x 0.205" W (10.00mm x 5.20mm)
• Height: 0.080" (2.04mm) maximum
• Termination count: 2
• Compliance: ROHS3, MSL 1

The substitute part CSS2H-3920R-L300F meets all these criteria and is therefore electrically and mechanically interchangeable.
