1812GC472MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1812GC472MAT3A\SB is a 4700 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 2000V (2kV) operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package format is designed for general-purpose high-voltage applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and design continuity when the primary part number becomes unavailable or when tolerance specifications require adjustment.

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC472MAT3A\SB is determined by strict equivalence in the following critical parameters: capacitance value (4700 pF), voltage rating (2000V minimum), temperature coefficient (X7R), package format (1812/4532 Metric), and mounting type (Surface Mount MLCC). All identified substitutes maintain these core electrical and mechanical specifications.

Substitute parts are categorized into two groups:

Upgrade Substitutes — Parts with improved tolerance specifications (±10% versus ±20%) while maintaining all other electrical and mechanical parameters. These parts provide enhanced capacitance accuracy for applications requiring tighter tolerance control.

Parametric Equivalents — Parts with identical electrical specifications and tolerance ratings, differentiated only by packaging format or internal manufacturing series designation. These parts are direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with KYOCERA AVX and carry ROHS3 compliance certification. Selection between the main part and substitutes should be based on tolerance requirements and packaging format availability.

For applications requiring standard ±20% tolerance, both 1812GC472MAT3A\SB and 1812GC472MAT1A are functionally equivalent. The primary distinction is packaging format: 1812GC472MAT3A\SB is supplied in standard cut tape format, while 1812GC472MAT1A is supplied in tape and reel format. Selection between these two should be based on procurement volume and assembly line requirements.

For applications where improved capacitance accuracy is required, 1812GC472KAT1A and KGM43FR73D472KV both provide ±10% tolerance. 1812GC472KAT1A is available in cut tape and digi-reel packaging, while KGM43FR73D472KV is supplied in tape and reel format and belongs to the KGM HV series. The thickness specification for KGM43FR73D472KV is 0.087" (2.21mm), which represents a negligible 0.01mm variance from the standard 2.20mm specification and does not impact PCB layout or assembly compatibility.

All parts maintain identical operating temperature range (-55°C to 125°C), voltage rating (2000V), and moisture sensitivity classification (MSL 1), ensuring direct functional interchangeability within the specified electrical and environmental parameters.

Frequently Asked Questions (FAQ)

Q: Can 1812GC472KAT1A be used as a direct replacement for 1812GC472MAT3A\SB?

A: Yes. 1812GC472KAT1A is a direct functional substitute with identical electrical specifications. The primary difference is improved tolerance (±10% versus ±20%). This upgrade substitution is compatible with all applications designed for the original part. Packaging format differs (cut tape/digi-reel versus standard cut tape), which may affect procurement and assembly logistics but not electrical performance.

Q: What is the difference between 1812GC472KAT1A and KGM43FR73D472KV?

A: Both parts provide identical electrical specifications: 4700 pF capacitance, ±10% tolerance, 2000V rating, and X7R temperature coefficient. The differences are: KGM43FR73D472KV belongs to the KGM HV series and is supplied in tape and reel format, while 1812GC472KAT1A uses standard KYOCERA AVX part numbering and is available in cut tape and digi-reel formats. Thickness specification for KGM43FR73D472KV is 0.087" (2.21mm) versus 0.087" (2.20mm) for 1812GC472KAT1A—a 0.01mm difference that does not affect PCB assembly compatibility.

Q: Is 1812GC472MAT1A equivalent to 1812GC472MAT3A\SB?

A: Yes. 1812GC472MAT1A is a parametric equivalent with identical electrical specifications and ±20% tolerance. Both parts are supplied by KYOCERA AVX with the same capacitance, voltage rating, and temperature coefficient. The distinction is packaging format: 1812GC472MAT1A is supplied in tape and reel format, while 1812GC472MAT3A\SB is supplied in cut tape format.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity) rating. All parts are classified under ECCN EAR99 and HTSUS 8532.24.0020. Compliance specifications are identical across all parts.

Q: Can I use a ±10% tolerance part in a design specified for ±20% tolerance?

A: Yes. Parts with ±10% tolerance (1812GC472KAT1A and KGM43FR73D472KV) can be used in applications designed for ±20% tolerance, as the tighter tolerance represents an upgrade in capacitance accuracy. The design will continue to function within specification.

Q: What packaging formats are available for these parts?

A: 1812GC472MAT3A\SB is supplied in cut tape format. 1812GC472KAT1A is available in cut tape and digi-reel formats. KGM43FR73D472KV is supplied in tape and reel format. 1812GC472MAT1A is supplied in tape and reel format. Selection should be based on assembly equipment compatibility and procurement volume requirements.
