1808SC222MAT1A Equivalent & Substitute Parts

Part Overview

The 1808SC222MAT1A is a 2200 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC222MAT1A is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 2200 pF (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variations:

• Voltage Rating: Equal to or greater than 1500V
• Tolerance: ±10% or ±20%
• Manufacturer: Different manufacturers permitted if all other parameters match
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

Substitute parts are grouped into two categories based on voltage rating: parts maintaining 1500V rating with improved tolerance, and parts with upgraded 2000V rating.

Parameter Comparison

Engineering Selection Recommendations

1808SC222KAT1A - Direct substitute maintaining 1500V rating with improved ±10% tolerance. Identical mechanical dimensions and thermal characteristics. All compliance certifications match the original part. Recommended for applications where tighter capacitance tolerance is required without voltage derating.

1808GC222MAT1A - Voltage-upgraded substitute with 2000V rating and ±20% tolerance matching the original. Identical mechanical dimensions and thermal characteristics. All compliance certifications match the original part. Recommended for applications requiring higher voltage margin while maintaining original tolerance specification.

1808GC222KAT1A - Voltage-upgraded substitute with 2000V rating and improved ±10% tolerance. Identical mechanical dimensions and thermal characteristics. All compliance certifications match the original part. Recommended for applications requiring both higher voltage margin and tighter capacitance tolerance.

VPDP202W222K1GV001E - Cross-manufacturer substitute from Johanson Dielectrics Inc. with 2000V rating and ±10% tolerance. Mechanical dimensions vary slightly (0.185" L x 0.080" W vs. 0.181" L x 0.079" W; thickness 0.085" vs. 0.087"). All compliance certifications match the original part. Recommended for applications where cross-manufacturer sourcing is acceptable and slight dimensional variation does not impact PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can 1808SC222KAT1A replace 1808SC222MAT1A in all applications?

A: Yes. The 1808SC222KAT1A maintains the same 1500V voltage rating, identical mechanical dimensions, and X7R temperature coefficient. The only difference is improved ±10% tolerance versus ±20%. This substitution is electrically and mechanically compatible.

Q: What is the advantage of using 1808GC222KAT1A over the original part?

A: The 1808GC222KAT1A provides two improvements: voltage rating increased from 1500V to 2000V, and tolerance improved from ±20% to ±10%. This part offers greater design margin and tighter capacitance specification while maintaining identical mechanical compatibility.

Q: Can VPDP202W222K1GV001E be used as a direct replacement?

A: VPDP202W222K1GV001E is electrically compatible with identical capacitance, voltage rating (2000V), tolerance (±10%), and temperature coefficient (X7R). However, mechanical dimensions differ slightly: length 0.185" vs. 0.181", width 0.080" vs. 0.079", and thickness 0.085" vs. 0.087". Verify PCB layout clearances before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental and regulatory compliance status.

Q: What is the difference between the KYOCERA AVX and Johanson Dielectrics parts?

A: Both manufacturers provide equivalent electrical performance at 2200 pF, 2000V, X7R, with ±10% tolerance. The primary difference is mechanical dimensions: Johanson part is slightly larger in length and width but thinner. Verify PCB footprint compatibility before cross-manufacturer substitution.

Q: Can I use a 2000V rated part in a circuit designed for 1500V?

A: Yes. A 2000V rated capacitor is electrically compatible in a 1500V circuit. The higher voltage rating provides additional design margin and reliability. No circuit modifications are required.
