Part Overview

The 1812CC102MAT1A is a 1000 pF ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 630V rated voltage. This surface mount MLCC (multilayer ceramic capacitor) in 1812 (4532 metric) package is designed for general purpose applications requiring high voltage performance. The part is active and in production with 768 units currently in stock. Substitute parts are identified when design requirements change, such as increased voltage margin, tighter tolerance specifications, or alternative packaging formats while maintaining the same capacitance value and physical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812CC102MAT1A is determined by the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 1000 pF (all substitutes maintain this value)
• Temperature Coefficient: X7R (all substitutes maintain this specification)
• Package / Case: 1812 (4532 Metric) (all substitutes use identical footprint)
• Mounting Type: Surface Mount, MLCC (all substitutes are surface mount)
• Operating Temperature Range: -55°C to 125°C (all substitutes maintain this range)
• RoHS Status: ROHS3 Compliant (all substitutes maintain compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes maintain MSL-1)

Variable Parameters (Substitution Basis):

• Voltage - Rated: 630V (main part) → 1000V, 1500V, 2000V, 2500V, or 3000V (substitutes)
• Tolerance: ±20% (main part) → ±10% or ±20% (substitutes)
• Thickness (Max): 0.071" (1.80mm) for 630V/1000V/1500V/2000V → 0.087" (2.20mm) for 3000V → 0.110" (2.80mm) for 2500V

Substitutes are grouped by voltage rating. Higher voltage ratings provide increased safety margin in applications where the original 630V specification may be insufficient. Tolerance selection depends on circuit requirements for capacitance accuracy.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and active product status. Selection between substitutes depends on application voltage requirements and tolerance specifications:

For 1000V applications: 1812AC102KAT1A (±10% tolerance) or 1812AC102MAT1A (±20% tolerance) provide direct voltage upgrade with identical thickness.

For 1500V applications: 1812SC102MAT1A offers intermediate voltage rating with ±20% tolerance and standard thickness.

For 2000V applications: Four options are available. 1812GC102KAT1A and 1812GC102MAT1A use standard KYOCERA AVX numbering. KGM43ER73D102KV and KGM43ER73D102MV are from the KGM - HV series. All maintain 0.071" (1.80mm) thickness. Selection between ±10% and ±20% tolerance depends on circuit accuracy requirements.

For 2500V applications: 1812WC102KAT1A requires increased thickness of 0.110" (2.80mm), necessitating PCB layout verification for clearance.

For 3000V applications: 1812HC102KAT1A and KGM43FR73U102KV both provide maximum voltage rating. 1812HC102KAT1A uses standard numbering with 0.087" (2.20mm) thickness. KGM43FR73U102KV is from the KGM - HV series with 0.087" (2.21mm) thickness. Both require PCB height clearance verification.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a direct replacement? A: Yes. All substitute parts maintain identical capacitance (1000 pF), temperature coefficient (X7R), package footprint (1812/4532 metric), and operating temperature range (-55°C to 125°C). Higher voltage ratings provide increased safety margin. Verify PCB clearance for parts with increased thickness (2500V and 3000V ratings).

Q: What is the difference between ±10% and ±20% tolerance options? A: Tolerance specifies the allowable deviation from the nominal 1000 pF capacitance value. ±10% tolerance (900-1100 pF) is tighter and suitable for applications requiring precise capacitance. ±20% tolerance (800-1200 pF) is acceptable for general purpose applications with less stringent accuracy requirements.

Q: Are KGM series parts compatible with KYOCERA AVX standard numbering parts? A: Yes. KGM43ER73D102KV, KGM43ER73D102MV, and KGM43FR73U102KV are from the KYOCERA AVX KGM - HV series. They maintain identical electrical specifications, package dimensions, and compliance certifications as their standard-numbered equivalents. Selection between series depends on availability and packaging format requirements.

Q: What packaging formats are available? A: Substitute parts are supplied in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or standard packaging. Verify packaging format compatibility with your assembly process before ordering.

Q: Do all parts maintain MSL-1 (Unlimited) moisture sensitivity? A: Yes. All listed parts maintain Moisture Sensitivity Level 1, requiring no special moisture control during storage or handling.

Q: Which substitute provides the best inventory availability? A: 1812GC102MAT1A (2000V, ±20% tolerance) has the highest inventory at 14,533 units. KGM43ER73D102MV (2000V, ±20% tolerance, KGM - HV series) has 6,649 units available.
