Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF6040U is determined by strict equivalence across the following critical parameters:

• Resistance value: 604 Ohms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The CRCW2010604RFKEF manufactured by Vishay Dale meets all specified parameters and qualifies as a direct substitute. Both parts share identical electrical characteristics, thermal performance, package dimensions, and automotive compliance certifications.
