Substitute Part Grouping Explanation

The 1812AC273KAT1A qualifies as an upgrade substitute for the 1812CC273MAT9A based on the following substitution criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 0.027 µF (identical)
• Temperature Coefficient: X7R (identical)
• Package / Case: 1812 (4532 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Upgrade Characteristics:

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

The 1812AC273KAT1A maintains all critical electrical and mechanical parameters while providing enhanced voltage capability and improved tolerance performance, making it suitable for applications requiring higher voltage headroom or tighter capacitance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC273MAT9A and 1812AC273KAT1A are Active status components manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812AC273KAT1A represents an upgrade path offering higher voltage rating (1000V versus 630V) and improved tolerance specification (±10% versus ±20%). Selection between these parts depends on circuit voltage requirements and tolerance specifications. The increased thickness of the 1812AC273KAT1A (2.80mm versus 1.80mm) must be verified for PCB assembly compatibility. Both parts maintain identical capacitance, temperature coefficient, operating temperature range, and moisture sensitivity characteristics, ensuring functional equivalence in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 1812AC273KAT1A directly replace the 1812CC273MAT9A in existing designs?

A: Yes, the 1812AC273KAT1A is functionally compatible as a direct substitute. Both parts share identical capacitance (0.027 µF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and package dimensions (1812 / 4532 Metric). The primary difference is the increased thickness (2.80mm versus 1.80mm), which must be confirmed for PCB assembly clearance.

Q: What are the key differences between these two parts?

A: The 1812AC273KAT1A provides higher voltage rating (1000V versus 630V) and tighter tolerance (±10% versus ±20%). These represent improvements over the 1812CC273MAT9A for applications requiring greater voltage margin or more precise capacitance values.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). No compliance differences exist between the two components.

Q: Does the thickness difference affect PCB design?

A: The 1812AC273KAT1A has maximum thickness of 2.80mm compared to 1.80mm for the 1812CC273MAT9A. PCB assembly height clearance and component placement must accommodate this 1.00mm difference.

Q: Can the 1812CC273MAT9A be used in applications designed for the 1812AC273KAT1A?

A: The 1812CC273MAT9A can be used only if the circuit voltage rating does not exceed 630V and the ±20% tolerance is acceptable. The lower voltage rating and wider tolerance make it unsuitable for designs requiring 1000V rating or ±10% tolerance specification.
