Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC682MAT1A and 1812GC682KAT1A are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The 1812GC682KAT1A provides enhanced specifications through higher voltage rating (2000V versus 630V) and improved tolerance (±10% versus ±20%), while maintaining identical package dimensions and thermal characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The increased thickness of the substitute part (2.80mm versus 1.80mm) must be verified against available PCB assembly space.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC682KAT1A replace the 1812CC682MAT1A in all applications?

A: The 1812GC682KAT1A is electrically compatible as a direct substitute. However, the increased thickness (2.80mm versus 1.80mm) requires verification of available vertical clearance on the PCB assembly. If space constraints exist, the original part must be retained.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: The ±10% tolerance of the 1812GC682KAT1A provides tighter capacitance control, resulting in more predictable circuit performance. Applications requiring precise capacitance values benefit from this specification.

Q: Are both parts suitable for high-voltage applications?

A: The 1812CC682MAT1A is rated for 630V operation. The 1812GC682KAT1A is rated for 2000V operation. Selection depends on the circuit voltage requirement. The higher-rated part provides additional safety margin in high-voltage designs.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications.
