Substitute Part Grouping Explanation

Substitution eligibility for the CRCW080552R3FKEBC is determined by strict equivalence across the following critical parameters:

• Resistance value: 52.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CR0805-FX-52R3ELF manufactured by Bourns Inc. meets all substitution criteria and is classified as a direct equivalent part.
