1812CA151MAT1A Ceramic Capacitor 150pF 630V C0G/NP0 Equivalent & Substitute Parts

Part Overview

The 1812CA151MAT1A is a surface-mount multilayer ceramic capacitor (MLCC) manufactured by KYOCERA AVX with a capacitance of 150 pF, rated voltage of 630V, and C0G/NP0 temperature coefficient. This component is classified as Active and is suitable for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified based on matching capacitance value, package size, temperature coefficient, and compliance certifications while allowing for voltage rating upgrades and tolerance variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CA151MAT1A is determined by the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 150 pF
• Temperature Coefficient: C0G, NP0
• Package / Case: 1812 (4532 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May be equal to or greater than 630V
• Tolerance: May be ±5%, ±10%, or ±20%
• Manufacturer: KYOCERA AVX or other qualified manufacturers
• Packaging: Tape & Reel (TR) or equivalent

All identified substitute parts maintain the same capacitance value, temperature stability, and physical package while offering enhanced voltage ratings and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active products with ROHS3 compliance and REACH Unaffected status, meeting the same regulatory and environmental requirements as the primary part.

Voltage Rating Considerations: Substitute parts with higher voltage ratings (1000V, 2000V, 3000V) are electrically compatible with applications designed for 630V operation. The higher voltage rating provides additional safety margin and does not degrade performance in lower-voltage circuits.

Tolerance Selection: The primary part specifies ±20% tolerance. Substitute parts with ±5% or ±10% tolerance offer improved capacitance accuracy for applications requiring tighter specifications. Selection should be based on circuit design requirements.

Thickness Variation: Parts rated at 2000V and 3000V exhibit increased thickness (0.087" and 0.071" respectively) compared to the primary part (0.057"). PCB layout and component clearance must accommodate these dimensional changes.

Manufacturer Equivalence: KYOCERA AVX and TDK Corporation parts listed are functionally equivalent within the specified parameters. Selection may be based on availability, supply chain considerations, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000V-rated capacitor in place of the 630V 1812CA151MAT1A? A: Yes. Higher voltage-rated capacitors are electrically compatible with lower-voltage applications. The 1812AA151JAT1A and 1812AA151KAT1A (1000V rated) are direct substitutes and provide additional voltage margin.

Q: What is the difference between ±5%, ±10%, and ±20% tolerance parts? A: Tolerance specifies the allowable deviation from the nominal 150 pF capacitance value. ±20% allows ±30 pF deviation, ±10% allows ±15 pF deviation, and ±5% allows ±7.5 pF deviation. Select based on circuit accuracy requirements.

Q: Are the thickness differences between substitute parts significant? A: Yes. The 2000V and 3000V rated parts are thicker (0.087" and 0.071" respectively) than the 630V part (0.057"). Verify PCB layout clearances and component stacking height before substitution.

Q: Can I substitute the TDK C4532C0G3F151K160KA for the KYOCERA AVX 1812CA151MAT1A? A: Yes. Both parts share identical capacitance, temperature coefficient, package size, and compliance certifications. The TDK part offers 3000V rating and ±10% tolerance. Verify dimensional compatibility with your PCB layout due to minor length variation (0.177" vs 0.181").

Q: Which substitute part offers the best availability? A: The C4532C0G3F151K160KA (TDK) has the highest inventory at 24,949 pieces. The 1812AA151KAT1A (KYOCERA AVX, 1000V) has 3,300 pieces available.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory standards as the primary part.
