1812SC222MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1812SC222MAT3A\SB is a 2200 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) with X7R temperature coefficient and ±20% tolerance. This component is actively produced and widely used in general-purpose high-voltage applications. Substitute parts are identified based on matching capacitance, package size, and operating temperature range while accommodating variations in voltage rating, tolerance, and temperature coefficient specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC222MAT3A\SB is determined by the following criteria:

Primary Matching Parameters (Required):

• Capacitance: 2200 pF (exact match)
• Package / Case: 1812 (4532 Metric) (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)

Secondary Allowable Variations:

• Voltage Rating: Equal to or greater than 1500V
• Tolerance: ±10% or ±20%
• Temperature Coefficient: X7R or X7S
• Manufacturer: Different manufacturers acceptable if electrical and mechanical specifications align

Substitute parts are grouped into two categories based on voltage rating upgrade:

Upgrade Category (2000V / 2kV Rating): Parts with higher voltage rating than the original specification, providing enhanced voltage margin while maintaining identical capacitance and package dimensions.

Manufacturer Recommended Category: Parts with alternative temperature coefficient (X7S) offering different temperature stability characteristics within the same voltage class.

Parameter Comparison

Engineering Selection Recommendations

1812GC222KAT1A (KYOCERA AVX Upgrade): Direct upgrade from the same manufacturer with identical physical dimensions and operating temperature range. Voltage rating increased to 2000V with improved tolerance (±10%). Recommended for applications requiring higher voltage margin while maintaining KYOCERA AVX supply chain continuity. Product status is Active.

C4532X7R3D222K130KA (TDK Corporation Upgrade): TDK equivalent with 2000V rating and ±10% tolerance. Slightly reduced physical dimensions (0.177" L vs 0.181" L, 0.059" thickness vs 0.071" thickness) remain compatible with 1812 package footprints. Product status is Active. Suitable for space-constrained applications.

C4532X7R3D222M130KA (TDK Corporation Alternative): TDK part with 2000V rating and ±20% tolerance matching the original tolerance specification. Reduced physical dimensions identical to C4532X7R3D222K130KA. Product status is Not For New Designs; use only for legacy system maintenance or replacement applications.

C4532X7S3D222K160KA (TDK Corporation, X7S Coefficient): Manufacturer-recommended alternative with X7S temperature coefficient instead of X7R. X7S provides tighter capacitance stability across the operating temperature range compared to X7R. 2000V rating with ±10% tolerance. Product status is Active. Select when temperature stability is a critical design parameter.

Frequently Asked Questions (FAQ)

Q: Can I use a 2000V rated capacitor in place of the 1500V original? A: Yes. Higher voltage ratings provide increased safety margin and are electrically compatible. The 2000V substitute parts maintain identical capacitance and operating temperature range, making them direct functional replacements.

Q: What is the difference between X7R and X7S temperature coefficients? A: Both X7R and X7S are high-K dielectric materials with similar operating temperature ranges (-55°C ~ 125°C). X7S provides tighter capacitance tolerance across temperature variations compared to X7R. Selection depends on circuit requirements for temperature stability.

Q: Are the TDK parts with reduced dimensions (0.177" L x 0.059" thickness) compatible with my PCB layout designed for the original 0.181" L x 0.071" thickness? A: Yes. The reduced dimensions are physically smaller and will fit within footprints designed for the larger original part. Verify PCB pad spacing and clearance to ensure proper placement. The 1812 (4532 Metric) package designation remains consistent across all substitute parts.

Q: Why is C4532X7R3D222M130KA marked "Not For New Designs"? A: This part is in legacy status and may have limited future availability. For new designs, select C4532X7R3D222K130KA (same specifications with Active status) or other Active-status alternatives.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the original part.
