Key Parameters

Substitute Part Grouping Explanation

The 1812AC273KAT1A qualifies as a direct substitute based on the following criteria:

Matching Parameters:

• Capacitance: 0.027 µF (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 1812 (4532 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 1 (Unlimited) (identical)
• Manufacturer: KYOCERA AVX (identical)

Upgrade Parameters:

• Voltage Rating: 1000V (1kV) versus 630V (higher rating provides enhanced voltage margin)
• Tolerance: ±10% versus ±20% (tighter tolerance specification)

The substitute part maintains all critical electrical and mechanical parameters while providing improved voltage headroom and tolerance performance. The physical dimensions remain compatible with the 1812 package footprint.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for current applications. The 1812AC273KAT1A provides enhanced electrical performance through higher voltage rating (1000V versus 630V) and improved tolerance specification (±10% versus ±20%), while maintaining identical capacitance, temperature coefficient, and operating temperature range. Physical footprint compatibility is confirmed for the 1812 (4532 Metric) package. The thickness difference (2.80mm versus 1.80mm) must be evaluated against PCB assembly clearance requirements. Both parts are manufactured by KYOCERA AVX with unlimited moisture sensitivity level, ensuring consistent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can 1812AC273KAT1A directly replace 1812CC273MAT3A\SB in existing designs?

A: Yes, the substitute part maintains identical capacitance (0.027 µF), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and 1812 (4532 Metric) package footprint. The higher voltage rating (1000V) and tighter tolerance (±10%) represent performance improvements. PCB assembly clearance must accommodate the increased thickness (2.80mm versus 1.80mm).

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (1000V upgrade from 630V), tolerance specification (±10% versus ±20%), and component thickness (2.80mm versus 1.80mm). Capacitance, temperature coefficient, and package dimensions remain identical.

Q: Are both parts ROHS3 compliant?

A: Yes, both 1812CC273MAT3A\SB and 1812AC273KAT1A are ROHS3 compliant with REACH Unaffected status.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: Does the thickness difference affect PCB assembly?

A: The substitute part (1812AC273KAT1A) has maximum thickness of 2.80mm compared to 1.80mm for the original part. PCB design must confirm adequate clearance above the component to prevent interference with other assembly elements.
