Compare the capacitor and its holder

The 315 manual gives the capacitor and capacitor holder separate identifiers. The holder listing does not identify the capacitor itself. Keep the manual's replacement requirement and each model's source scope; this establishes no replacement or interchangeability.

Separate references with their own source scope. This comparison establishes no replacement or interchangeability.
