KYOCERA AVX 1812GC472MAT3A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1812GC472MAT3A is a 4700 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient in 1812 (4532 Metric) surface mount package. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant, REACH unaffected, and maintains active product status. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and packaging compatibility while accounting for tolerance variations and packaging format differences.

Substitute Part Grouping Explanation

Substitute parts for the 1812GC472MAT3A are classified into two categories based on allowed parameter variations:

Upgrade Substitutes — Parts with improved tolerance specifications while maintaining all other electrical and mechanical parameters:

• 1812GC472KAT1A: Tighter ±10% tolerance with Cut Tape (CT) & Digi-Reel® packaging
• KGM43FR73D472KV: Tighter ±10% tolerance from the KGM - HV series with Tape & Reel (TR) packaging

Parametric Equivalents — Parts with identical electrical specifications and packaging format:

• 1812GC472MAT1A: Matching ±20% tolerance with Tape & Reel (TR) packaging

Substitution is valid when the following parameters remain constant or improve:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating: 2000V minimum (2kV)
• Temperature coefficient: X7R
• Package / Case: 1812 (4532 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.181" L × 0.126" W (4.60mm × 3.20mm)
• Compliance: ROHS3 and REACH status maintained

Tolerance may be tightened from ±20% to ±10% without affecting circuit compatibility. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) does not affect electrical performance and may be selected based on assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility across applications.

1812GC472KAT1A is suitable for applications where tighter capacitance tolerance (±10%) provides improved circuit performance compared to the ±20% specification of the main part. This upgrade maintains identical electrical ratings and mechanical compatibility while offering enhanced precision. Cut Tape and Digi-Reel packaging formats support both manual and automated assembly processes.

KGM43FR73D472KV from the KYOCERA AVX KGM - HV series provides the same ±10% tolerance upgrade with Tape & Reel packaging optimized for high-volume automated assembly. Thickness specification of 0.087" (2.21mm) represents a negligible variation within standard manufacturing tolerances and does not affect PCB layout or assembly compatibility.

1812GC472MAT1A is a direct parametric equivalent with matching ±20% tolerance and identical electrical specifications. Tape & Reel packaging format differs from the main part's standard packaging but does not affect electrical performance. This part is suitable for applications where tolerance and electrical characteristics are the primary selection criteria.

Frequently Asked Questions (FAQ)

Q: Can 1812GC472KAT1A or KGM43FR73D472KV be used as direct replacements for 1812GC472MAT3A?

A: Yes. Both parts maintain the same capacitance value (4700 pF), voltage rating (2000V), temperature coefficient (X7R), package dimensions (1812 / 4532 Metric), and operating temperature range (-55°C to 125°C). The ±10% tolerance of these upgrade parts is tighter than the ±20% specification of the main part, making them functionally compatible and electrically superior for precision-critical applications.

Q: What is the difference between the packaging formats (Cut Tape, Digi-Reel, and Tape & Reel)?

A: Packaging format affects supply and assembly logistics but not electrical performance. Cut Tape (CT) and Digi-Reel® are suitable for lower-volume or manual assembly processes. Tape & Reel (TR) is optimized for high-speed automated pick-and-place assembly. All three formats contain identical components with the same electrical specifications.

Q: Is the thickness variation between 1812GC472MAT3A (2.20mm) and KGM43FR73D472KV (2.21mm) significant?

A: No. The 0.01mm difference falls within standard manufacturing tolerances for ceramic capacitors and does not affect PCB layout, assembly clearances, or electrical performance. Both parts are mechanically and electrically interchangeable.

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with applications requiring these certifications.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts carry this rating, meaning they do not require special moisture-controlled storage or baking procedures prior to assembly, simplifying inventory management and reducing handling complexity.

Q: Can tolerance be tightened from ±20% to ±10% without affecting circuit design?

A: Yes. Tightening tolerance improves capacitance accuracy and reduces circuit performance variation. If the original design was validated with ±20% tolerance, upgrading to ±10% tolerance parts enhances reliability and consistency without requiring design changes.
