1812SC682MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC682MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 6800 pF, rated for 1500V (1.5kV), and featuring X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with 935 pieces available in new original stock. Substitute parts are identified when equivalent electrical performance can be maintained while accommodating design constraints, supply availability, or performance upgrades within the same physical package footprint.

Substitute Part Grouping Explanation

The 1812GC682KAT1A qualifies as a substitute for the 1812SC682MAT1A based on the following substitution criteria:

Matching Parameters:

  • Capacitance: 6800 pF (identical)
  • Temperature Coefficient: X7R (identical)
  • Operating Temperature Range: -55°C to 125°C (identical)
  • Package / Case: 1812 (4532 Metric) (identical)
  • Physical Dimensions: 0.181" L x 0.126" W, 0.110" thickness (identical)
  • Mounting Type: Surface Mount, MLCC (identical)
  • RoHS Status: ROHS3 Compliant (identical)
  • Moisture Sensitivity Level: 1 (Unlimited) (identical)

Upgraded Parameters:

  • Voltage Rating: 2000V (2kV) versus 1500V (1.5kV) — higher voltage rating provides enhanced margin
  • Tolerance: ±10% versus ±20% — tighter tolerance specification

The substitute part maintains all critical electrical and mechanical compatibility parameters while offering improved voltage headroom and tolerance performance. Both parts are active products with established supply availability.

Engineering Selection Recommendations

Both the 1812SC682MAT1A and 1812GC682KAT1A are active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812GC682KAT1A offers a performance upgrade path with higher voltage rating (2000V versus 1500V) and improved tolerance specification (±10% versus ±20%), while maintaining identical physical package dimensions and thermal characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications. Both parts are suitable for applications requiring high-voltage ceramic capacitors in the 1812 package format with X7R temperature stability.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC682KAT1A directly replace the 1812SC682MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (6800 pF), package dimensions (1812/4532 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The substitute part is physically and electrically compatible for direct board-level substitution.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating and tolerance. The 1812GC682KAT1A is rated for 2000V (2kV) with ±10% tolerance, compared to the 1812SC682MAT1A rated for 1500V (1.5kV) with ±20% tolerance. Both differences favor the substitute part.

Q: Are there any packaging differences?

A: The 1812SC682MAT1A is supplied in standard packaging, while the 1812GC682KAT1A is supplied in Tape & Reel (TR) format. Both use the identical 1812 (4532 Metric) component package. Tape & Reel packaging is standard for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020. Both have Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for new designs?

A: The 1812GC682KAT1A is recommended for new designs due to its higher voltage rating margin and tighter tolerance specification, provided circuit requirements do not mandate the specific characteristics of the original part.
