Key Parameters

Substitute Part Grouping Explanation

The 1812GC822KAT1A qualifies as a direct substitute based on the following criteria:

Matching Parameters:

• Identical capacitance value: 8200 pF
• Identical package / case: 1812 (4532 Metric)
• Identical mounting type: Surface Mount, MLCC
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

Upgrade Characteristics:

• Higher voltage rating: 2000V (2kV) versus 1000V (1kV)
• Tighter tolerance: ±10% versus ±20%
• Increased physical thickness: 2.80mm versus 1.80mm

The substitute part maintains all critical electrical and mechanical compatibility parameters while providing enhanced voltage margin and improved tolerance specification. The increased thickness is the only dimensional change and must be verified against PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC822MATME and 1812GC822KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application voltage requirements and tolerance specifications:

The 1812AC822MATME is appropriate for circuits operating at or below 1000V with tolerance requirements of ±20% or wider.

The 1812GC822KAT1A is appropriate for circuits requiring voltage ratings of 2000V or for applications where ±10% tolerance specification is mandatory. This part provides enhanced voltage margin and improved capacitance accuracy. The increased thickness (2.80mm versus 1.80mm) must be confirmed compatible with PCB layout and component placement constraints before selection.

Both parts maintain identical thermal performance across the -55°C to 125°C operating range and are suitable for general-purpose high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A replace the 1812AC822MATME in all applications?

A: The 1812GC822KAT1A is electrically compatible as a direct substitute. The primary consideration is physical thickness: the substitute part measures 2.80mm maximum thickness compared to 1.80mm for the original. PCB layout and component clearance must be verified before substitution.

Q: What is the significance of the voltage rating difference?

A: The 1812GC822KAT1A is rated for 2000V operation versus 1000V for the 1812AC822MATME. This higher rating provides additional voltage margin in circuits operating near the 1000V limit. For circuits operating below 1000V, both parts are functionally equivalent from a voltage perspective.

Q: How does the tolerance difference affect circuit performance?

A: The 1812AC822MATME specifies ±20% tolerance while the 1812GC822KAT1A specifies ±10% tolerance. The tighter tolerance of the substitute part results in improved capacitance accuracy. For applications with strict capacitance value requirements, the 1812GC822KAT1A provides better performance consistency.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance across this range.

Q: What packaging formats are available?

A: The 1812AC822MATME is available in standard packaging. The 1812GC822KAT1A is available in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and order quantity.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1812AC822MATME and 1812GC822KAT1A are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
