Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1808AC222MAT1A are grouped based on the following allowed parameters:

Core Compatibility Parameters:

• Capacitance: 2200 pF (fixed across all substitutes)
• Temperature Coefficient: X7R (fixed across all substitutes)
• Operating Temperature Range: -55°C ~ 125°C (fixed across all substitutes)
• Package / Case: 1808 (4520 Metric) (fixed across all substitutes)
• Mounting Type: Surface Mount, MLCC (fixed across all substitutes)
• RoHS Status: ROHS3 Compliant (fixed across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed across all substitutes)

Variable Parameters Defining Substitution Groups:

• Voltage Rating: 1000V, 1500V, or 2000V
• Tolerance: ±20% or ±10%
• Thickness: 0.071" (1.80mm) or 0.087" (2.20mm)
• Packaging: Bulk or Tape & Reel (TR)

Substitutes are valid when voltage rating meets or exceeds the original specification, tolerance is equal or tighter, and physical dimensions remain compatible with board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Voltage Rating): The 1808AC222KAT1A is a direct replacement for the 1808AC222MAT1A. Both parts maintain 1000V rating and identical physical dimensions. The primary difference is tighter tolerance (±10% versus ±20%) and Tape & Reel packaging. This part is suitable when tighter capacitance tolerance is required and higher inventory availability is beneficial.

Upgraded Voltage Rating (1500V): The 1808SC222KAT1A provides 1500V rating with ±10% tolerance. Thickness increases to 0.087" (2.20mm). This part is suitable for applications requiring higher voltage margin while maintaining the same capacitance value. Board layout must accommodate the increased thickness.

Upgraded Voltage Rating (2000V): The 1808GC222MAT1A and 1808GC222KAT1A both provide 2000V rating. The KAT1A variant offers ±10% tolerance with 7782 units in stock, providing superior inventory availability. Thickness increases to 0.087" (2.20mm). The VPDP202W222K1GV001E from Johanson Dielectrics Inc. offers equivalent 2000V rating with ±10% tolerance and the highest inventory level (11663 units). Dimensional variations are minimal (0.185" L x 0.080" W versus 0.181" L x 0.079" W; thickness 0.085" versus 0.087").

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and X7R temperature coefficient. Product status is active for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can 1808AC222KAT1A replace 1808AC222MAT1A directly? A: Yes. Both parts share identical voltage rating (1000V), capacitance (2200 pF), temperature coefficient (X7R), and physical dimensions (0.181" L x 0.079" W x 0.071" thickness). The KAT1A variant offers tighter tolerance (±10% versus ±20%) and comes in Tape & Reel packaging.

Q: What is the impact of increased thickness in higher voltage rated parts? A: Parts rated 1500V and 2000V have increased thickness (0.087" or 2.16-2.20mm) compared to the 1000V part (0.071" or 1.80mm). Board layout and component placement must accommodate this dimension change. Electrical performance and capacitance value remain unchanged.

Q: Are cross-manufacturer substitutes available? A: Yes. The VPDP202W222K1GV001E from Johanson Dielectrics Inc. is a 2000V rated alternative with ±10% tolerance and 1808 package compatibility. Dimensional tolerances are within acceptable ranges (0.185" L x 0.080" W x 0.085" thickness). This part is designated for SMPS Filtering applications and maintains full ROHS3 compliance.

Q: What tolerance should be selected for critical applications? A: The ±10% tolerance variants (1808AC222KAT1A, 1808SC222KAT1A, 1808GC222KAT1A, VPDP202W222K1GV001E) provide tighter capacitance control compared to the ±20% variants. Selection depends on circuit requirements and acceptable capacitance drift across operating temperature range.

Q: Is Tape & Reel packaging compatible with bulk packaging requirements? A: Tape & Reel packaging is standard for automated assembly processes. If bulk packaging is required, only the 1808AC222MAT1A is available in that format. All other substitutes are supplied in Tape & Reel packaging.

Q: What is the voltage derating consideration when selecting higher rated parts? A: Substituting with higher voltage rated parts (1500V or 2000V) provides additional voltage margin and safety factor. No derating is required; the part operates safely at or below its rated voltage. Circuit design voltage requirements determine the minimum acceptable rating.
