Substitute Part Grouping Explanation

Substitution of the CD15FD501FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. A valid substitute must maintain identical specifications in the following categories:

Electrical Parameters: Capacitance value (500 pF), tolerance (±1%), and rated voltage (500 V) must be exact matches. The mica dielectric material and operating temperature range (-55°C to 125°C) define the performance envelope and cannot be altered.

Mechanical Parameters: The through-hole radial mounting configuration, lead spacing (0.232" / 5.90 mm), physical dimensions (0.469" L x 0.220" W / 11.90 mm x 5.60 mm), and maximum seated height (0.402" / 10.20 mm) must be preserved to ensure PCB compatibility and assembly process alignment.

Functional Classification: Both the main part and substitute must be classified as general-purpose mica capacitors within the CD15 series manufactured by Cornell Dubilier Electronics.

Substitutes are identified based on these parameters alone. No additional technical criteria are applied.
