Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSS2725JTL500 is determined by the following critical parameters that must remain constant or compatible:

• Resistance value: 0.5 mOhms (exact match required)
• Power rating: 4W (exact match required)
• Composition: Metal Element (exact match required)
• Package type: Nonstandard 2725 (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Operating temperature range: -55°C ~ 225°C (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The CSS2725FTL500 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. The tolerance specification differs (±1% versus ±5%), which represents an upgrade in precision while maintaining full compatibility with the original design requirements.
