Substitute Part Grouping Explanation

Substitution of the 2220Y3K00331MXT is permissible with the 2220Y4K00331KXT based on the following criteria:

Identical Parameters:

• Capacitance: 330 pF (maintained)
• Temperature Coefficient: X7R (maintained)
• Operating Temperature Range: -55°C ~ 125°C (maintained)
• Package / Case: 2220 (5750 Metric) (maintained)
• Mounting Type: Surface Mount, MLCC (maintained)
• Features: Soft Termination (maintained)
• RoHS Status: ROHS3 Compliant (maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained)

Upgraded Parameters:

• Voltage Rating: 4000V (4kV) versus 3000V (3kV)
• Tolerance: ±10% versus ±20%

Frequently Asked Questions (FAQ)

Q: Can the 2220Y4K00331KXT replace the 2220Y3K00331MXT in existing designs?

A: Yes. The substitute part maintains identical capacitance, temperature coefficient, operating temperature range, package dimensions, and mounting characteristics. The higher voltage rating (4kV versus 3kV) and improved tolerance (±10% versus ±20%) are compatible with applications designed for the original part.

Q: What are the physical compatibility considerations?

A: Both parts use the 2220 (5750 Metric) package with identical dimensions of 0.224" L x 0.197" W (5.70mm x 5.00mm) and maximum thickness of 0.098" (2.50mm). Surface mount placement and reflow profiles are compatible.

Q: How do the tolerance specifications differ?

A: The main part 2220Y3K00331MXT has ±20% tolerance, while the substitute 2220Y4K00331KXT has ±10% tolerance. The tighter tolerance of the substitute part provides improved capacitance accuracy.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8532.24.0020). Moisture Sensitivity Level is 1 (Unlimited) for both.

Q: What is the voltage rating difference?

A: The main part is rated for 3000V (3kV), while the substitute is rated for 4000V (4kV). The substitute provides 1000V additional voltage margin.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 2220Y3K00331MXT and 2220Y4K00331KXT are manufactured by Knowles Syfer and belong to the FlexiCap™ series.
