Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC562MAT3A\SB is determined by the following critical parameters:

• Capacitance Value: Must remain 5600 pF to maintain circuit functionality
• Package / Case: Must be 1812 (4532 Metric) to ensure mechanical and electrical compatibility with PCB layouts
• Mounting Type: Must be Surface Mount MLCC to match assembly processes
• Temperature Coefficient: Must be X7R to preserve temperature stability characteristics
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance Standards: Must maintain ROHS3 compliance and REACH Unaffected status

The identified substitute part 1812SC562KAT1A meets all critical parameters while offering enhanced voltage rating (1500V vs 1000V) and improved tolerance (±10% vs ±20%), making it suitable for applications requiring higher voltage margins or tighter capacitance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC562MAT3A\SB and 1812SC562KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current and future applications.

The 1812AC562MAT3A\SB is the primary selection for applications with 1000V voltage requirements and standard ±20% tolerance specifications. This part offers established inventory availability with 887 units in stock.

The 1812SC562KAT1A serves as a direct substitute when higher voltage margins are required (1500V rating) or when tighter capacitance tolerance (±10%) is specified. The increased thickness (2.80mm vs 1.80mm) must be verified against PCB assembly clearance constraints. This substitute provides enhanced reliability in high-voltage stress environments while maintaining identical footprint dimensions and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can 1812SC562KAT1A replace 1812AC562MAT3A\SB in existing designs?

A: Yes, provided PCB assembly clearance accommodates the increased thickness of 2.80mm (versus 1.80mm). Both parts share identical length and width dimensions (4.60mm x 3.20mm), capacitance value (5600 pF), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C).

Q: What are the key differences between these parts?

A: The substitute offers three primary differences: higher voltage rating (1500V vs 1000V), tighter tolerance (±10% vs ±20%), and greater thickness (2.80mm vs 1.80mm). Capacitance, package, and thermal characteristics remain identical.

Q: Are both parts suitable for -55°C to 125°C operating environments?

A: Yes. Both parts maintain X7R temperature coefficient characteristics across the full -55°C to 125°C operating range, ensuring stable capacitance performance throughout this temperature spectrum.

Q: Do packaging differences affect assembly compatibility?

A: Both parts use identical 1812 (4532 Metric) Surface Mount packages with matching footprints (0.181" L x 0.126" W). The thickness difference (1.80mm vs 2.80mm) may affect clearance with adjacent components or conformal coating processes and should be verified during design review.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both 1812AC562MAT3A\SB and 1812SC562KAT1A are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
