Frequently Asked Questions (FAQ)

Q: Can the 2220Y4K00331KXT replace the 2220Y2K00331MXT in existing designs?

A: Yes. Both parts share identical package format (2220), physical dimensions, mounting type (surface mount), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The substitute part is electrically and mechanically compatible without requiring PCB redesign.

Q: What is the difference in voltage rating between these parts?

A: The main part is rated for 2000V (2kV), while the substitute is rated for 4000V (4kV). The higher voltage rating of the substitute provides increased safety margin in high-voltage applications.

Q: How do the tolerance specifications differ?

A: The main part specifies ±20% tolerance, while the substitute specifies ±10% tolerance. The tighter tolerance of the substitute part may be required for applications with strict capacitance value requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 2220Y2K00331MXT and 2220Y4K00331KXT are supplied in Tape & Reel (TR) packaging in the 2220 (5750 Metric) case format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), ensuring equivalent regulatory compliance.

Q: What is the soft termination feature?

A: Soft termination is a feature that reduces mechanical stress on component terminations during thermal cycling and board flexing, improving reliability in applications subject to mechanical stress or vibration.
