Equivalent & Substitute Parts for 1812AC273MATRE

Part Overview

The 1812AC273MATRE is a 0.027 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active and available in stock with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and tolerance optimization for circuit implementations.

Substitute Part Grouping Explanation

Substitution for the 1812AC273MATRE is determined by the following critical parameters that must remain constant or improve:

• Capacitance Value: 0.027 µF (exact match required)
• Voltage Rating: 1000V minimum (equal or higher acceptable)
• Temperature Coefficient: X7R (required for temperature stability)
• Package / Case: 1812 (4532 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C minimum (functional requirement)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The substitute part 1812AC273KAT1A meets all these criteria with an improved tolerance specification (±10% versus ±20%), making it a direct upgrade option while maintaining identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both 1812AC273MATRE and 1812AC273KAT1A are active products from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812AC273KAT1A offers improved tolerance performance at ±10% compared to the ±20% tolerance of the 1812AC273MATRE, while maintaining identical electrical ratings, physical dimensions, and thermal characteristics. Selection between these parts depends on circuit tolerance requirements and packaging specifications. The 1812AC273KAT1A is supplied in Tape & Reel (TR) packaging, whereas the 1812AC273MATRE packaging format is not specified. Both parts are suitable for applications requiring high-voltage ceramic capacitors in the 1812 form factor with stable X7R performance across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 1812AC273KAT1A replace 1812AC273MATRE in existing designs?

A: Yes. Both parts share identical capacitance (0.027 µF), voltage rating (1000V), temperature coefficient (X7R), package dimensions (1812/4532 Metric), and operating temperature range (-55°C to 125°C). The 1812AC273KAT1A provides tighter tolerance (±10% versus ±20%), making it a direct substitute with improved performance characteristics.

Q: What is the significance of the tolerance difference between these parts?

A: The 1812AC273MATRE has ±20% tolerance, while 1812AC273KAT1A has ±10% tolerance. Tighter tolerance (±10%) provides more precise capacitance values, which is beneficial for circuits with strict capacitance requirements. The choice depends on circuit design specifications and acceptable capacitance variation.

Q: Are there packaging differences between these substitute parts?

A: The 1812AC273KAT1A is specified as Tape & Reel (TR) packaging. The 1812AC273MATRE packaging format is not specified in the provided data. Both parts use the same 1812 (4532 Metric) case size with identical physical dimensions (0.181" L x 0.126" W, 0.110" max thickness).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both 1812AC273MATRE and 1812AC273KAT1A are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.
