Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F8663CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 866 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of terminations: 2
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Acceptable Variation:

• Power rating: Substitute parts may equal or exceed the 0.063W (1/16W) specification
• Additional certifications: Automotive AEC-Q200 qualification is permissible as an upgrade feature
