Key Parameters

Substitute Part Grouping Explanation

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

• Capacitance Value: Must remain 5600 pF (no deviation permitted)
• Package Type: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Temperature Coefficient: Must be X7R to maintain thermal stability characteristics
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Mounting Type: Must be Surface Mount, MLCC
• Compliance: Must maintain ROHS3 and REACH compliance status

The identified substitute part 1812SC562KAT1A meets all mandatory substitution criteria while offering enhanced electrical performance through increased voltage rating (1500V vs. 1000V) and improved tolerance (±10% vs. ±20%). Both parts share identical capacitance, package geometry, temperature coefficient, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC562MAT3A and 1812SC562KAT1A are active production parts with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications. The 1812SC562KAT1A represents an upgrade path offering superior voltage margin (1500V vs. 1000V) and tighter capacitance tolerance (±10% vs. ±20%), making it suitable for applications requiring enhanced reliability or stricter component specifications. The primary design consideration is the increased thickness of the substitute part (2.80mm vs. 1.80mm), which must be verified against PCB assembly constraints and available board space. Both parts maintain identical footprint dimensions and thermal characteristics, supporting direct substitution in applications where the additional voltage headroom and tolerance improvement are beneficial.

Frequently Asked Questions (FAQ)

Q: Can 1812SC562KAT1A be used as a direct replacement for 1812AC562MAT3A?

A: Yes, within mechanical constraints. Both parts share identical capacitance (5600 pF), package footprint (1812/4532 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The substitute offers higher voltage rating (1500V vs. 1000V) and better tolerance (±10% vs. ±20%). However, the increased thickness (2.80mm vs. 1.80mm) must be accommodated in PCB assembly design.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating, tolerance, and thickness. The 1812SC562KAT1A provides 50% higher voltage rating and half the tolerance specification, while being 1.0mm thicker. Capacitance value, package type, and thermal characteristics remain identical.

Q: Are both parts compliant with current regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Does the thickness difference affect PCB assembly?

A: The 1.0mm thickness increase (from 1.80mm to 2.80mm) must be considered during PCB design and assembly planning. Verify clearance with surrounding components and reflow profile compatibility before implementation.

Q: Can the 1812AC562MAT3A be substituted with 1812SC562KAT1A in existing designs?

A: Substitution is electrically valid and offers performance improvements. Mechanical verification of the increased thickness against available board space and component clearances is required before implementation.
