Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSSH2512JT2L00 is determined by the following critical parameters:

• Resistance value: 2 mOhms (exact match required)
• Power rating: 3W (exact match required)
• Package type: 2512 (6432 Metric) (exact match required)
• Composition: Metal Element (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C to 225°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)

The CSSH2512FT2L00 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The primary difference is an improved tolerance specification of ±1% compared to the original ±5%, which represents an upgrade in precision without affecting form factor, thermal characteristics, or automotive compliance.
