1812CC103MATBE Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812CC103MATBE is a 10000 pF (10 nF) ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1812 (4532 Metric) package is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812CC103MATBE are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Capacitance value: 10000 pF
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount, MLCC

Mechanical Parameters (Must Match):

• Package / Case: 1812 (4532 Metric)
• Physical footprint: 0.181" L × 0.126" W (4.60mm × 3.20mm)

Allowable Variations:

• Voltage rating: Equal to or greater than 630V (upgrades to 1000V are acceptable)
• Tolerance: ±10% or ±20% (both acceptable for general-purpose applications)
• Thickness: Variations within component height constraints
• Manufacturer: Different qualified manufacturers acceptable

All identified substitutes maintain identical capacitance, temperature coefficient, and package footprint while meeting or exceeding the voltage specification and compliance requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among the qualified substitutes should be based on the following factors:

Voltage Margin Consideration: All substitute parts are rated at 1000V, providing a 370V margin above the original 630V specification. This upgrade is electrically compatible and does not introduce design conflicts.

Tolerance Selection: The 1812AC103KAT1A and C4532X7R3A103K200KA offer ±10% tolerance, providing tighter capacitance control compared to the ±20% tolerance of the main part and KGM43FR73A103MV. Selection depends on circuit requirements for capacitance precision.

Manufacturer Availability: KYOCERA AVX substitutes (1812AC103KAT1A and KGM43FR73A103MV) maintain consistent design lineage with the original part. The TDK Corporation alternative (C4532X7R3A103K200KA) offers significantly higher inventory availability (86,839 units) compared to KYOCERA AVX options.

Physical Dimensions: The C4532X7R3A103K200KA exhibits a 0.1mm reduction in length (4.50mm vs. 4.60mm) and increased thickness (2.20mm vs. 1.80mm). Verify PCB layout clearances before selection if space constraints exist.

Frequently Asked Questions (FAQ)

Q: Can the 1812AC103KAT1A replace the 1812CC103MATBE directly?

A: Yes. Both parts share identical capacitance (10000 pF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 1812 package footprint. The 1812AC103KAT1A provides upgraded voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%), making it a direct electrical and mechanical substitute.

Q: What is the difference between KGM43FR73A103MV and 1812AC103KAT1A?

A: Both are KYOCERA AVX 10000 pF X7R capacitors in 1812 package with 1000V rating. The primary difference is tolerance: KGM43FR73A103MV maintains ±20% tolerance (matching the original part), while 1812AC103KAT1A offers ±10% tolerance. KGM43FR73A103MV is part of the KGM - HV series. Selection depends on circuit tolerance requirements.

Q: Is the TDK C4532X7R3A103K200KA compatible with the original PCB layout?

A: The C4532X7R3A103K200KA maintains the same 1812 package designation and footprint width (3.20mm). However, length is reduced by 0.1mm (4.50mm vs. 4.60mm) and thickness is increased by 0.4mm (2.20mm vs. 1.80mm). Verify PCB pad spacing and component height clearances before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the original 1812CC103MATBE.

Q: Can I use a 1000V-rated capacitor in a circuit designed for 630V?

A: Yes. Using a higher voltage-rated capacitor in a lower voltage application is electrically safe and does not introduce functional conflicts. The 1000V rating provides additional safety margin and reliability.

Q: What packaging format is available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
