Substitute Part Grouping Explanation

Substitute parts for the CMP1206AFX-4701ELF are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance Value: 4.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.75W minimum (exact match required)
• Package: 1206 (3216 Metric) surface mount (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)
• Automotive Compliance: AEC-Q200 (exact match required)
• Environmental Features: Anti-Sulfur, Moisture Resistant, Pulse Withstanding (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.
