1812CC104MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812CC104MAT1A is a 0.1 µF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 630V operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or exceeding the core electrical specifications: 0.1 µF capacitance, 630V minimum rated voltage, X7R temperature coefficient, and 1812 (4532 metric) package dimensions. Substitutes may vary in tolerance, voltage rating, thickness, and manufacturer, provided they maintain functional compatibility within the specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 0.1 µF (exact match required)
• Temperature Coefficient: X7R (required for stable performance across operating range)
• Package / Case: 1812 (4532 Metric) (required for PCB footprint compatibility)
• Mounting Type: Surface Mount, MLCC (required for assembly compatibility)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute acceptable; tighter tolerance is an upgrade)
• Voltage - Rated: 630V minimum (higher voltage ratings are acceptable upgrades)
• Thickness: Variation permitted within mechanical assembly constraints
• Manufacturer: Any qualified manufacturer meeting electrical and compliance specifications

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• MSL 1 (Unlimited) preferred; higher MSL ratings acceptable
• REACH Unaffected status maintained

All substitute parts listed meet these criteria and are electrically and mechanically compatible with the 1812CC104MAT1A.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Active Production: 1812CC104KAT1A (KYOCERA AVX) - Same manufacturer as the original part with improved ±10% tolerance. Active production status ensures long-term availability and supply chain stability.

Alternative Active Production Options:

• C1812C104KBRAC7800 (KEMET) - Active status with lowest profile (1.55 mm thickness), beneficial for space-constrained designs. Highest inventory availability (12,960 pcs).
• C1812C104KDRAC7800 (KEMET) - Active status with upgraded 1000V rating, providing additional voltage margin. Recommended for applications requiring enhanced reliability in high-voltage environments.
• GRM43DR72J104KW01L (Murata Electronics) - Active status with highest inventory (107,400 pcs), ensuring consistent supply availability. Identical thickness to original part.

Legacy / Not For New Designs:

• C4532X7R2J104M230KA (TDK Corporation) - Not recommended for new designs; use only for legacy system maintenance or repair.
• SMK432B7104KM-T (Taiyo Yuden) - Not recommended for new designs; use only for legacy system maintenance or repair.

All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating. Selection should prioritize active production status for new designs and long-term supply chain security.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1812CC104MAT1A with a part having ±10% tolerance instead of ±20%? A: Yes. A ±10% tolerance part is a direct upgrade and provides tighter capacitance control. All listed substitutes with ±10% tolerance are electrically compatible and functionally superior in terms of tolerance performance.

Q: What is the difference between 630V and 1000V rated substitutes? A: The C1812C104KDRAC7800 is rated for 1000V (1 kV), providing a 370V safety margin above the original 630V specification. This higher voltage rating is suitable for applications requiring enhanced reliability or operating in high-voltage environments. The 1000V part is a direct upgrade and maintains all other electrical parameters.

Q: Are there any physical size differences I should consider? A: Yes. While all parts use the 1812 (4532 metric) package, thickness varies: the original part is 2.20 mm, KEMET C1812C104KBRAC7800 is 1.55 mm (thinnest), and Taiyo Yuden SMK432B7104KM-T is 2.70 mm (thickest). Verify PCB assembly clearance before selecting a substitute with different thickness.

Q: Why are some substitutes marked "Not For New Designs"? A: Parts marked "Not For New Designs" are in legacy or end-of-life status. Manufacturers recommend using active production alternatives for new product development to ensure long-term supply chain stability and access to technical support.

Q: Which substitute has the best inventory availability? A: GRM43DR72J104KW01L (Murata Electronics) has the highest inventory at 107,400 pcs, followed by C1812C104KBRAC7800 (KEMET) at 12,960 pcs. High inventory availability reduces lead time risk for procurement.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original part.
