1812CC103MAT9A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812CC103MAT9A is a 10000 pF (0.01 µF) high-voltage ceramic capacitor manufactured by KYOCERA AVX in 1812 (4532 Metric) surface-mount package format. This X7R temperature coefficient capacitor operates across -55°C to 125°C and is rated for 630V applications. The part maintains Active product status 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, design flexibility, or voltage margin requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC103MAT9A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 10000 pF (exact match required)
• Temperature Coefficient: X7R (ensures stable performance across operating range)
• Package / Case: 1812 (4532 Metric) (ensures mechanical and electrical compatibility on PCB)
• Mounting Type: Surface Mount, MLCC (maintains assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (functional equivalence)

Allowable Variation Parameters:

• Voltage Rating: May exceed 630V (higher voltage rating provides design margin and reliability improvement)
• Tolerance: ±10% or ±20% (both acceptable; tighter tolerance represents upgrade path)
• Physical Thickness: Variation within package envelope (1.80mm to 2.80mm) acceptable if PCB clearance permits

Compliance Requirements:

• RoHS3 Compliant (mandatory for equivalent substitution)
• MSL 1 rating (unlimited moisture sensitivity maintained)

Parameter Comparison

Engineering Selection Recommendations

1812SC103KAT1A (KYOCERA AVX) Direct manufacturer equivalent with elevated voltage rating (1500V). Tighter tolerance specification (±10%) provides improved capacitance accuracy. Increased thickness (2.80mm) requires PCB clearance verification. Suitable for applications requiring maximum voltage margin and tolerance control.

1812AC103KAT1A (KYOCERA AVX) Upgrade option with 1000V rating and ±10% tolerance. Maintains compact profile (2.20mm thickness) compatible with space-constrained designs. Represents balanced improvement in voltage margin and tolerance specification while preserving original form factor.

KGM43FR73A103MV (KYOCERA AVX, KGM - HV Series) High-voltage series variant rated 1000V with ±20% tolerance matching original specification. Thickness (2.21mm) aligns with standard 1812 package envelope. Maintains original tolerance while providing voltage upgrade path.

C4532X7R3A103K200KA (TDK Corporation) Cross-manufacturer substitute from TDK with 1000V rating and ±10% tolerance. Slight dimensional variation in length (4.50mm vs. 4.60mm) remains within 1812 package specification. Highest inventory availability (86,839 pcs) supports supply chain flexibility. All compliance certifications (ROHS3, MSL 1) maintained.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812CC103MAT9A with a part rated at higher voltage? A: Yes. Parts rated 1000V or 1500V are direct substitutes. Higher voltage rating provides design margin and improved reliability without affecting circuit performance. Verify PCB layout accommodates any thickness variation.

Q: What is the difference between ±10% and ±20% tolerance specifications? A: Both tolerances are acceptable substitutes. ±10% tolerance (1812SC103KAT1A, 1812AC103KAT1A, C4532X7R3A103K200KA) provides tighter capacitance accuracy. ±20% tolerance (1812CC103MAT9A, KGM43FR73A103MV) is standard for general-purpose applications. Selection depends on circuit sensitivity to capacitance variation.

Q: Are KYOCERA AVX and TDK parts interchangeable? A: Yes, when electrical parameters match. C4532X7R3A103K200KA (TDK) is mechanically and electrically equivalent to KYOCERA AVX options. Verify PCB assembly equipment compatibility with slight dimensional differences (4.50mm vs. 4.60mm length).

Q: Does increased package thickness affect PCB assembly? A: Thickness variation (1.80mm to 2.80mm) is within 1812 package specification. Verify PCB clearance above component if space constraints exist. Standard pick-and-place equipment accommodates this range without adjustment.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring regulatory and environmental equivalence.

Q: Which substitute offers best inventory availability? A: C4532X7R3A103K200KA (TDK) provides highest stock level (86,839 pcs). KYOCERA AVX alternatives range from 1,932 to 2,712 pcs. Selection should balance availability with manufacturer preference and supply chain strategy.
