Substitute Part Grouping Explanation

Substitution eligibility for the 1206Y2000221MXT is determined by strict adherence to the following parameters:

Fixed Parameters (Must Match Exactly):

• Capacitance: 220 pF
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Thickness (Max): 0.063" (1.60mm)
• Operating Temperature Range: -55°C ~ 125°C
• Series: FlexiCap™
• Manufacturer: Knowles Syfer

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May be equal to or greater than 200V
• Temperature Coefficient: May differ (X7R, C0G/NP0, or equivalent)
• Tolerance: May be tighter (±5% acceptable for ±20% requirement)

The substitute part 1206Y6300221JCT meets all fixed parameters while providing enhanced voltage rating (630V) and improved tolerance (±5%) with C0G/NP0 temperature coefficient, maintaining full compatibility within the 1206 package footprint and Boardflex Sensitive application environment.

Parameter Comparison

Engineering Selection Recommendations

Both the 1206Y2000221MXT and 1206Y6300221JCT are active products from Knowles Syfer's FlexiCap™ series with identical ROHS3 compliance, REACH unaffected status, and MSL 1 ratings. Both components are suitable for Boardflex Sensitive applications with soft termination features.

The 1206Y6300221JCT substitute provides a higher voltage rating (630V versus 200V) and tighter tolerance (±5% versus ±20%), with C0G/NP0 temperature coefficient replacing X7R. These characteristics maintain full mechanical and electrical compatibility within the 1206 package while offering enhanced performance margins for applications requiring greater voltage headroom or improved capacitance stability across temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can 1206Y6300221JCT be used as a direct replacement for 1206Y2000221MXT?

A: Yes. Both parts share identical capacitance (220 pF), package dimensions (1206/3216 Metric), mounting type (Surface Mount MLCC), and operating temperature range (-55°C ~ 125°C). The substitute provides higher voltage rating and tighter tolerance while maintaining full footprint and application compatibility.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the operating temperature range. C0G/NP0 provides ±30 ppm/°C, delivering superior capacitance stability across temperature variations. Both coefficients are suitable for the -55°C ~ 125°C operating range specified for these components.

Q: Are both parts ROHS3 compliant?

A: Yes. Both 1206Y2000221MXT and 1206Y6300221JCT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. Higher voltage rating does not degrade performance in circuits designed for 200V operation. The 630V rating of 1206Y6300221JCT provides additional safety margin and is fully compatible with 200V circuit requirements.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use identical 1206 (3216 Metric) package specifications with 0.126" L x 0.063" W dimensions and 0.063" (1.60mm) maximum thickness, ensuring identical PCB footprint compatibility.
