Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0720R5L is determined by the following critical parameters:

• Resistance Value: Must be 20.5 Ohms (exact match required)
• Package Format: Must be 0402 (1005 Metric) for PCB footprint compatibility
• Power Rating: Must be minimum 0.063W (1/16W) to handle circuit power dissipation
• Composition: Thin film construction ensures temperature stability and tolerance performance
• Operating Temperature Range: Must support -55°C to 155°C minimum
• RoHS3 Compliance: Required for regulatory and supply chain compatibility

The CPF0402B20R5E1 qualifies as a direct substitute based on matching all critical parameters while offering enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C).
