Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMP0805AFX-1003ELF is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (100 kOhms), tolerance (±1%), and power rating (0.5W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805/2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and maximum seated height (0.024" / 0.60mm) ensure PCB footprint compatibility and assembly process alignment.

Compliance & Environmental: AEC-Q200 automotive qualification, anti-sulfur construction, moisture resistance, and pulse withstanding capability are mandatory for functional equivalence in target applications. ROHS3 compliance and MSL 1 rating must be maintained.

Composition & Construction: Thick film technology and two-termination configuration define the component's electrical behavior and reliability characteristics.

Substitute parts must satisfy all parameters listed above without exception.

Parameter Comparison
