Engineering Selection Recommendations

Primary Selection (CD42FC563JO3F): Select the CD42FC563JO3F when ROHS3 compliance and REACH unaffected status are required by design specifications, regulatory requirements, or customer mandates. This part is the preferred choice for applications subject to European Union environmental directives or equivalent compliance frameworks.

Alternative Selection (CD42FC563JO3): The CD42FC563JO3 is electrically and mechanically equivalent and may be selected when RoHS3 compliance is not a design requirement and REACH affected status is acceptable within the application context. This part provides identical electrical performance and mechanical compatibility with lower compliance overhead.

Inventory Considerations: CD42FC563JO3F maintains 921 pieces in stock. CD42FC563JO3 maintains 680 pieces in stock. Selection between these parts should account for availability and supply chain lead times.

Frequently Asked Questions (FAQ)

Q: Are CD42FC563JO3F and CD42FC563JO3 electrically interchangeable?

A: Yes. Both parts have identical capacitance (0.056 µF), tolerance (±5%), voltage rating (300 V), dielectric material (mica), and operating temperature range (-55°C to 125°C). They are direct electrical equivalents.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts share identical mechanical specifications: radial through-hole mounting, 1.063" (27.00 mm) lead spacing, and physical envelope dimensions of 1.461" L × 0.421" W (37.10 mm × 10.70 mm). They occupy the same footprint and require no PCB layout modifications.

Q: What is the difference between CD42FC563JO3F and CD42FC563JO3?
