Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805JTR250 is determined by the following critical parameters:

• Resistance value: 250 mOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thick Film (exact match required)
• Features: Current Sense capability (required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• Termination count: 2 (exact match required)

The CSR0805FKR250 qualifies as a substitute through identical mechanical and electrical specifications with improved tolerance performance (±1% versus ±5%), maintaining all critical parameters while offering enhanced precision for current sensing applications.
