1812CC273MATRE Equivalent & Substitute Parts

Part Overview

The 1812CC273MATRE is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.027 µF capacitance with 630V voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with 923 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, design optimization, or inventory management when the primary part becomes unavailable or when design requirements necessitate upgraded electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC273MATRE is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF (no tolerance variation acceptable for direct substitution)
• Package / Case: Must be 1812 (4532 metric) to ensure mechanical and electrical compatibility with existing PCB layouts
• Mounting Type: Must be Surface Mount, MLCC to maintain assembly process compatibility
• Temperature Coefficient: Must be X7R to preserve temperature stability characteristics
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: May be equal to or greater than 630V; higher voltage ratings provide design margin and are acceptable substitutes
• Tolerance: May be tighter (lower) than ±20%; tighter tolerances are acceptable upgrades
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1812AC273KAT1A qualifies as an upgrade substitute by maintaining all critical parameters while providing enhanced voltage rating (1000V vs. 630V) and improved tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC273MATRE and 1812AC273KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and MSL 1 rating, ensuring regulatory compliance and handling flexibility.

The 1812AC273KAT1A represents an upgrade substitute with the following advantages:

• Voltage Margin: 1000V rating provides 370V additional design margin over the 630V requirement, reducing stress on the component and improving reliability in high-voltage applications
• Tolerance Improvement: ±10% tolerance versus ±20% provides tighter capacitance control, beneficial for circuits requiring precise capacitive values
• Same Footprint: Identical 4.60mm × 3.20mm land pattern ensures direct PCB compatibility without layout modifications

The primary consideration is the increased thickness (2.80mm vs. 1.80mm), which must be verified against PCB clearance constraints and assembly equipment capabilities. Both parts share identical electrical characteristics (X7R, -55°C to 125°C) and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 1812AC273KAT1A be used as a direct replacement for 1812CC273MATRE?

A: Yes, with one mechanical consideration. The substitute has identical capacitance, temperature coefficient, and operating range. The footprint is identical (4.60mm × 3.20mm). However, the thickness increases from 1.80mm to 2.80mm maximum. Verify that your PCB design and assembly equipment accommodate this height difference before implementation.

Q: What is the primary advantage of using 1812AC273KAT1A?

A: The substitute provides two engineering benefits: (1) higher voltage rating (1000V vs. 630V), offering greater design margin and stress reduction, and (2) tighter tolerance (±10% vs. ±20%), enabling more precise capacitance control in sensitive circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812CC273MATRE and 1812AC273KAT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting current environmental and regulatory requirements.

Q: Does the capacitance value change between these parts?

A: No. Both parts are rated at 0.027 µF. The tolerance specification differs (±20% vs. ±10%), but the nominal capacitance value is identical.

Q: What is the impact of the thickness difference?

A: The substitute is 1.00mm thicker (2.80mm vs. 1.80mm maximum). This affects PCB clearance above the component and may impact assembly equipment clearance. Verify your design constraints before selecting the substitute.

Q: Can I use 1812CC273MATRE as a substitute for 1812AC273KAT1A?

A: No. The main part has a lower voltage rating (630V vs. 1000V) and wider tolerance (±20% vs. ±10%). Using a lower-rated component in place of a higher-rated specification is not acceptable for engineering substitution.
