Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of the 50V original part? A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage circuits. The 100V and 200V rated substitutes provide additional design margin and are suitable for 50V applications.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R (original) provides ±15% capacitance variation across -55°C to 125°C. C0G/NP0 (substitutes) provides superior stability with ±0.3% variation. C0G/NP0 is preferred for precision applications requiring stable capacitance across temperature extremes.

Q: Are KEMET and KYOCERA AVX parts interchangeable? A: Yes, when matching capacitance, voltage rating, tolerance, package form factor, and temperature coefficient. Both manufacturers produce 0805 ceramic capacitors with identical physical dimensions and electrical specifications.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical characteristics remain identical regardless of packaging type.

Q: Can I substitute a ±1% tolerance part for the ±5% original? A: Yes. Tighter tolerance parts (±1%, ±2%) are direct substitutes for looser tolerance specifications (±5%). The substitute will meet or exceed the original tolerance requirement.

Q: Are all listed substitutes in active production? A: Yes. All substitute parts listed maintain Active product status with current inventory availability.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and manufacturing processes.
