1812CC472MAT3A Equivalent & Substitute Parts

Part Overview

The 1812CC472MAT3A is a 4700 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient and ±20% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package is designed for general purpose high voltage applications across an operating temperature range of -55°C to 125°C. The part is active and ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when design requirements allow for higher voltage ratings, improved tolerance specifications, or alternative packaging formats while maintaining the same capacitance value, package footprint, and temperature coefficient.

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and MSL 1 rating, matching the regulatory and environmental requirements of the 1812CC472MAT3A.

Voltage Upgrade Path: Parts 1812AC472KAT1A and C4532X7R3A472K160KA provide 1000V rating with improved ±10% tolerance, suitable for applications requiring higher voltage margin. Parts 1812GC472KAT1A, 1812GC472MAT1A, and KGM43FR73D472KV offer 2000V rating for maximum voltage headroom.

Tolerance Consideration: The original 1812CC472MAT3A specifies ±20% tolerance. Substitute parts with ±10% tolerance (1812AC472KAT1A, 1812GC472KAT1A, KGM43FR73D472KV, C4532X7R3A472K160KA) provide tighter capacitance control when circuit design requires improved accuracy.

Physical Dimensions: Parts rated at 2000V (1812GC472KAT1A, 1812GC472MAT1A, KGM43FR73D472KV) have increased thickness of 2.20mm or 2.21mm compared to 1.80mm for the original and 1000V-rated alternatives. Verify PCB layout clearance before selection.

Manufacturer Alternatives: TDK Corporation part C4532X7R3A472K160KA provides cross-manufacturer substitution with 1000V rating and ±10% tolerance. Dimensional variation (4.50mm length vs. 4.60mm) requires layout verification.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a direct substitute? A: Yes. Higher voltage ratings are electrically compatible substitutes when all other parameters (capacitance, package, temperature coefficient, operating temperature range) remain identical. The circuit will operate safely at the original 630V specification with a higher-rated component.

Q: What is the impact of tolerance differences between ±20% and ±10%? A: Tolerance defines the allowable capacitance deviation from the nominal 4700 pF value. ±20% allows 3760–5640 pF; ±10% allows 4230–5170 pF. Select ±10% tolerance parts when circuit performance requires tighter capacitance control.

Q: Are the 2000V-rated parts physically compatible with the original PCB layout? A: The 1812 (4532 metric) footprint remains identical, but thickness increases from 1.80mm to 2.20mm or 2.21mm for 2000V parts. Verify vertical clearance in your PCB design before substitution.

Q: Can I substitute the KYOCERA AVX part with the TDK Corporation equivalent? A: Yes. The C4532X7R3A472K160KA is electrically and mechanically compatible. Note the slight length difference (4.50mm vs. 4.60mm) requires layout verification to ensure proper fit within component placement constraints.

Q: Do all substitute parts maintain the same MSL and RoHS compliance? A: Yes. All identified substitutes are MSL 1 rated (unlimited moisture sensitivity protection) and ROHS3 compliant, matching the environmental and regulatory requirements of the original 1812CC472MAT3A.

Q: What packaging formats are available for these substitutes? A: The original 1812CC472MAT3A is supplied in standard packaging. Substitutes are available in Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats depending on the specific part number and manufacturer. Verify packaging availability with your supplier for production volume requirements.
