Substitute Part Grouping Explanation

The 1812GC822KAT1A qualifies as a substitute for the 1812SC822MATME based on the following substitution criteria:

Matching Parameters (Substitution Basis):

• Identical capacitance value: 8200 pF
• Identical package and physical footprint: 1812 (4532 Metric)
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C ~ 125°C
• Identical mounting type: Surface Mount, MLCC
• Identical physical dimensions: 0.181" L x 0.126" W (4.60mm x 3.20mm)
• Identical thickness: 0.110" (2.80mm)
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected

Upgraded Parameters (Substitution Advantage):

• Higher voltage rating: 2000V (2kV) versus 1500V (1.5kV)
• Tighter tolerance: ±10% versus ±20%

The substitute part maintains full electrical and mechanical compatibility while providing enhanced voltage margin and improved capacitance tolerance, making it suitable for applications requiring higher voltage headroom or stricter tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC822MATME and 1812GC822KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for current and future applications.

The 1812SC822MATME is the primary selection for applications with voltage requirements up to 1500V and tolerance specifications of ±20% or wider. This part offers cost efficiency for general-purpose high-voltage applications.

The 1812GC822KAT1A serves as the substitute when design requirements specify voltage ratings of 2000V or higher, or when capacitance tolerance must be held to ±10% or tighter. The identical physical footprint and thermal characteristics ensure direct PCB compatibility without layout modifications. The upgrade in voltage rating provides additional safety margin in high-voltage circuit designs, while the improved tolerance supports precision filtering and timing applications.

Selection between these parts depends solely on the circuit's voltage and tolerance requirements. Both parts are interchangeable from a mechanical and thermal standpoint, with the substitute offering enhanced electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A replace the 1812SC822MATME in existing designs?

A: Yes. The substitute part maintains identical physical dimensions (0.181" L x 0.126" W, 4.60mm x 3.20mm), thickness (0.110" / 2.80mm), and package type (1812 / 4532 Metric). No PCB layout modifications are required. The higher voltage rating (2kV versus 1.5kV) and tighter tolerance (±10% versus ±20%) are compatible with all applications designed for the original part.

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

A: The primary differences are voltage rating and tolerance. The 1812GC822KAT1A is rated for 2000V (2kV) compared to 1500V (1.5kV) for the 1812SC822MATME, and offers ±10% tolerance versus ±20%. All other electrical and mechanical specifications, including capacitance value (8200 pF), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical footprint, are identical.

Q: Are both parts available in the same packaging format?

A: The 1812SC822MATME is available in standard packaging, while the 1812GC822KAT1A is supplied in Tape & Reel (TR) format. Both use the same 1812 (4532 Metric) package case. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect electrical or mechanical compatibility.

Q: Which part should I select for a new design?

A: Selection depends on your circuit's voltage and tolerance requirements. If your design operates at voltages up to 1500V with ±20% tolerance acceptable, either part is suitable. If your design requires 2000V voltage rating or ±10% tolerance specification, the 1812GC822KAT1A is the appropriate choice. Both parts are Active products with full regulatory compliance.

Q: Are there any thermal or frequency limitations I should consider?

A: Both parts share identical thermal characteristics with an operating temperature range of -55°C to 125°C and X7R temperature coefficient, ensuring stable capacitance across this range. No additional thermal or frequency limitations apply beyond the specified operating temperature range.
