Substitute Part Grouping Explanation

The 1812GC822KAT1A qualifies as a substitute for the 1812SC822MAT1A based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Capacitance: 8200 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 / 4.60mm x 3.20mm (identical)
• Thickness: 0.110" (2.80mm) (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 rated voltage
• Tolerance: ±10% versus ±20% - tighter tolerance specification

The substitute part maintains full mechanical and thermal compatibility while providing enhanced electrical performance through higher voltage rating and improved capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC822MAT1A and 1812GC822KAT1A maintain Active product status from KYOCERA AVX and are ROHS3 Compliant with REACH Unaffected classification. The 1812GC822KAT1A provides enhanced performance specifications through higher voltage rating (2000V versus 1500V) and tighter capacitance tolerance (±10% versus ±20%), while maintaining identical mechanical form factor and thermal operating range. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications requiring higher voltage margin or improved capacitance accuracy within the same physical footprint.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A directly replace the 1812SC822MAT1A in existing designs?

A: Yes. Both parts share identical package dimensions (1812 / 4532 Metric), mounting type (Surface Mount MLCC), physical footprint (0.181" L x 0.126" W x 0.110" thickness), and thermal operating range (-55°C to 125°C). PCB layout and assembly processes require no modification.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (2000V versus 1500V) and capacitance tolerance (±10% versus ±20%). The substitute part provides higher voltage capability and tighter tolerance specification while maintaining all other electrical and mechanical characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812SC822MAT1A and 1812GC822KAT1A are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the significance of the X7R temperature coefficient?

A: X7R temperature coefficient indicates capacitance variation of ±15% across the -55°C to 125°C operating temperature range. Both parts maintain identical X7R characteristics, ensuring consistent performance across the full temperature spectrum.

Q: Does packaging differ between these parts?

A: The main part is specified without packaging notation, while the substitute part is available in Tape & Reel (TR) packaging. Both use identical component specifications; packaging format affects supply and handling only.
