Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC273MAT1A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.027 µF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Upgrade Parameters:

• Voltage Rating: May be equal to or greater than 630V
• Tolerance: May be equal to or tighter than ±20%
• Thickness: May vary within component physical constraints

The identified substitute part 1812AC273KAT1A meets all mandatory matching parameters and provides upgraded electrical specifications in voltage rating and tolerance, making it suitable for direct substitution in applications where the original part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC273MAT1A and 1812AC273KAT1A are Active status products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The substitute part 1812AC273KAT1A provides enhanced specifications through higher voltage rating (1000V versus 630V) and improved tolerance (±10% versus ±20%), while maintaining identical capacitance, temperature coefficient, and operating temperature range. The increased thickness of the substitute part (2.80mm versus 1.80mm) must be verified against PCB layout constraints and available board space. Both parts carry MSL 1 rating, indicating no moisture sensitivity limitations. Selection between these parts should be based on available board height clearance and whether the upgraded voltage and tolerance specifications align with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can 1812AC273KAT1A be used as a direct replacement for 1812CC273MAT1A?

A: Yes, 1812AC273KAT1A is electrically compatible as a substitute. Both parts share identical capacitance (0.027 µF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and package dimensions (4.60mm × 3.20mm). The substitute provides upgraded voltage rating and tighter tolerance. Physical board clearance must accommodate the increased thickness (2.80mm versus 1.80mm).

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

A: The primary differences are voltage rating (630V versus 1000V), tolerance (±20% versus ±10%), and component thickness (1.80mm versus 2.80mm). All other electrical and mechanical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes, both 1812CC273MAT1A and 1812AC273KAT1A are ROHS3 compliant with REACH unaffected status.

Q: Does the increased thickness of the substitute part affect PCB assembly?

A: The substitute part is 1.00mm thicker (2.80mm versus 1.80mm). This difference must be evaluated against available board height clearance and any height-sensitive design constraints in the application.

Q: Are both parts available in the same packaging format?

A: The main part is available in standard packaging, while the substitute part is specified as Tape & Reel (TR). Both use identical 1812 (4532 Metric) surface mount package format.
