• REACH compliance is mandated by supply chain or end-use regulations
• Higher inventory availability is advantageous for production scheduling

Both parts are active products from the same manufacturer and series, ensuring consistent quality and performance characteristics. The electrical and mechanical specifications are identical, confirming direct interchangeability at the circuit and assembly levels.

Frequently Asked Questions (FAQ)

Q: Can CDV19FF471JO3F be used as a direct replacement for CDV19FF471JO3 in existing designs?

A: Yes. The substitute part maintains identical capacitance (470 pF), tolerance (±5%), voltage rating (1 kV), dielectric material (mica), mounting type (through hole), package form (radial), lead spacing (0.343"), and physical dimensions. No circuit redesign or PCB layout modification is required.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications and inventory levels. CDV19FF471JO3F is RoHS3 compliant and REACH unaffected, while CDV19FF471JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and manufacturing processes, not to electrical performance or reliability. Both parts deliver identical capacitance, voltage rating, temperature stability, and operating characteristics.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both CDV19FF471JO3 and CDV19FF471JO3F are rated for 1 kV operation and are suitable for high-voltage general-purpose applications within the specified operating temperature range of -55°C to 125°C.

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

A: Yes. The radial through-hole package, lead spacing of 0.343" (8.70mm), and physical dimensions are identical. Both parts fit the same PCB footprint without modification.

Q: Which part should be selected for new designs?

A: For new designs, CDV19FF471JO3F is recommended when RoHS3 or REACH compliance is required. For applications without compliance constraints, either part is acceptable based on availability and cost considerations.
