Key Parameters

Substitute Part Grouping Explanation

The 1206Y6300221JCT qualifies as a direct substitute based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 220 pF (identical)
• Tolerance: ±5% (identical)
• Temperature Coefficient: C0G, NP0 (1B) (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Package / Case: 1206 (3216 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Physical Dimensions: 0.126" L x 0.063" W, 0.063" thickness (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• Manufacturer: Knowles Syfer (identical)
• Series: FlexiCap™ (identical)

Differing Parameter (Upgrade Characteristic):

• Voltage Rating: 630V (versus 200V in main part)

The substitute part maintains all critical electrical and mechanical parameters while providing enhanced voltage rating capability. This represents an upward-compatible substitution suitable for applications where higher voltage margin is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and full compliance with ROHS3 and REACH regulations. The 1206Y6300221JCT provides identical electrical performance at the specified operating conditions while offering increased voltage headroom. Selection between these parts depends on circuit voltage requirements:

• Use 1206Y2000221JCT where circuit design specifies 200V maximum rating and cost optimization is prioritized.
• Use 1206Y6300221JCT where circuit design permits higher voltage ratings or where design margin enhancement is required.

Both parts are suitable for Boardflex Sensitive applications and maintain soft termination characteristics. Inventory availability differs: 1090 units for the main part and 5801 units for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can 1206Y6300221JCT replace 1206Y2000221JCT in all applications?

A: Yes, provided the circuit board layout and design accommodate the substitute part. The 1206 package dimensions are identical, and all electrical parameters except voltage rating match exactly. The higher voltage rating of the substitute part does not create compatibility issues in circuits designed for 200V operation.

Q: What is the significance of the C0G/NP0 temperature coefficient designation?

A: C0G (IEC) and NP0 (EIA) designations indicate negligible capacitance change across the -55°C to 125°C operating temperature range. Both parts carry this specification, ensuring stable performance in temperature-sensitive applications.

Q: Are there any moisture sensitivity concerns with these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. Standard storage and handling practices apply.

Q: Does the higher voltage rating of 1206Y6300221JCT affect physical compatibility?

A: No. Both parts use identical 1206 (3216 Metric) packaging with matching dimensions (0.126" L x 0.063" W x 0.063" thickness). PCB footprints and reflow profiles remain unchanged.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
