Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206GC221MAT1A is determined by the following critical parameters:

• Capacitance: Must be 220 pF
• Voltage Rating: Must be 2000V (2kV) or higher
• Temperature Coefficient: X7R or X7S (both acceptable for general-purpose high-voltage applications)
• Package: 1206 (3216 Metric) surface-mount form factor
• Tolerance: ±20% or tighter (±10% acceptable as upgrade)
• Operating Temperature: -55°C ~ 125°C minimum
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts meeting these criteria are classified as direct equivalents or upgrades based on tolerance improvement and manufacturer availability.

Parameter Comparison

Engineering Selection Recommendations

1206GC221KAT1A (KYOCERA AVX) — Direct upgrade from the original part. Identical manufacturer, package, and temperature coefficient (X7R). Tolerance improved from ±20% to ±10%. Higher inventory availability (16,300 pieces). Recommended for applications requiring tighter capacitance tolerance without design modification.

CC1206KKX7RDBB221 (YAGEO) — Cross-manufacturer equivalent with ±10% tolerance and X7R temperature coefficient. Slightly reduced physical dimensions (length 3.20mm vs. 3.30mm, thickness 1.45mm vs. 1.80mm). All electrical parameters and compliance certifications match. Suitable for space-constrained designs. Inventory: 3,441 pieces.

C3216X7S3D221K085AA (TDK) — Manufacturer-recommended substitute with X7S temperature coefficient (tighter temperature stability than X7R). ±10% tolerance. Smallest physical profile (thickness 1.00mm). All electrical ratings and compliance requirements met. Inventory: 7,650 pieces. X7S coefficient provides enhanced performance in temperature-sensitive applications.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. Selection should be based on tolerance requirements, physical space constraints, and temperature stability needs.

Frequently Asked Questions (FAQ)

Q: Can 1206GC221KAT1A replace 1206GC221MAT1A directly?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical ratings (220 pF, 2000V, X7R, -55°C ~ 125°C) and package dimensions. The substitute offers improved ±10% tolerance versus ±20% on the original. No circuit redesign is required.

Q: What is the difference between X7R and X7S temperature coefficients?

A: Both X7R and X7S are acceptable for this application. X7R provides ±15% capacitance change over the -55°C ~ 125°C range. X7S provides tighter stability (±22% maximum). The C3216X7S3D221K085AA (TDK) with X7S coefficient is suitable when enhanced temperature performance is required.

Q: Are the YAGEO and TDK parts mechanically compatible with the original design?

A: Yes, all substitute parts use the 1206 (3216 Metric) package. The YAGEO part (CC1206KKX7RDBB221) has slightly reduced dimensions (3.20mm length, 1.45mm thickness) compared to the original (3.30mm length, 1.80mm thickness). The TDK part (C3216X7S3D221K085AA) has the smallest profile (1.00mm thickness). Both fit within standard 1206 footprints and are suitable for PCB assembly without modification.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All listed substitutes are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). ECCN and HTSUS classifications are identical across all parts.

Q: Which substitute should I select for high-volume production?

A: 1206GC221KAT1A (KYOCERA AVX) offers the highest inventory (16,300 pieces) and maintains the same manufacturer as the original, ensuring supply chain consistency. C3216X7S3D221K085AA (TDK) provides 7,650 pieces with enhanced temperature performance. CC1206KKX7RDBB221 (YAGEO) offers 3,441 pieces with space-saving dimensions.
