Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC562MAT3A\SB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 5600 pF (exact match required)
• Temperature Coefficient: X7R (ensures stable performance across operating range)
• Package / Case: 1812 (4532 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C ~ 125°C (functional equivalence)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 630V (higher voltage rating provides design margin)
• Tolerance: May be equal to or tighter than ±20% (improved tolerance is acceptable)

The substitute part 1812SC562KAT1A meets all mandatory matching criteria while providing upgraded voltage rating (1500V vs. 630V) and improved tolerance (±10% vs. ±20%), making it suitable for applications where higher voltage margin or tighter capacitance tolerance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC562MAT3A\SB and 1812SC562KAT1A are Active products with full ROHS3 compliance and MSL 1 rating, confirming ongoing manufacturing support and environmental compliance. Selection between these parts depends on circuit voltage requirements:

• 1812CC562MAT3A\SB is appropriate for applications with maximum operating voltage at or below 630V and where ±20% tolerance meets circuit specifications.

• 1812SC562KAT1A is appropriate for applications requiring voltage margin above 630V or where ±10% tolerance improves circuit performance. The higher voltage rating and tighter tolerance do not introduce compatibility issues in circuits designed for the original part.

Both components share identical physical dimensions (0.181" L x 0.126" W, 4.60mm x 3.20mm), identical capacitance value, and identical temperature coefficient, ensuring direct substitution at the assembly level.

Frequently Asked Questions (FAQ)

Q: Can 1812SC562KAT1A replace 1812CC562MAT3A\SB in existing designs?

A: Yes. The substitute part maintains identical capacitance (5600 pF), temperature coefficient (X7R), package dimensions (1812/4532 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (1500V vs. 630V) and improved tolerance (±10% vs. ±20%) do not create compatibility issues in circuits designed for the original part.

Q: What is the physical difference between these parts?

A: Both parts use the 1812 (4532 Metric) package with identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm). The substitute part has a maximum thickness of 0.110" (2.80mm) compared to 0.071" (1.80mm) for the original part. This thickness difference must be evaluated for PCB layout and assembly clearance.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812CC562MAT3A\SB and 1812SC562KAT1A are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does X7R temperature coefficient mean?

A: X7R indicates the capacitor maintains stable capacitance across the operating temperature range of -55°C to 125°C, with maximum capacitance change of ±15% over this range. Both parts share this specification.

Q: When should I use the substitute part instead of the original?

A: Use 1812SC562KAT1A when circuit design requires voltage margin above 630V or when tighter capacitance tolerance (±10%) improves circuit performance. Use the original 1812CC562MAT3A\SB when 630V rating and ±20% tolerance are sufficient and component thickness constraints favor the thinner profile.
