Substitute Part Grouping Explanation

Substitution of the 1812CC471MATME is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 470 pF (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package type: 1812 (4532 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 4.60mm L x 3.20mm W x 1.80mm Max Thickness (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or greater than 630V
• Tolerance: May be equal to or tighter than ±20%
• Manufacturer: KYOCERA AVX (same manufacturer for all listed substitutes)

All three substitute parts meet these criteria. The substitutes provide either higher voltage ratings (2kV or 3kV) or improved tolerance specifications (±10%), while maintaining identical physical form factor and electrical characteristics across all other parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active product status components manufactured by KYOCERA AVX with ROHS3 compliance and REACH unaffected status, matching the regulatory and compliance profile of the original 1812CC471MATME.

1812GC471KAT1A provides a voltage rating upgrade to 2kV with improved ±10% tolerance while maintaining identical physical dimensions and thermal characteristics.

1812HC471KAT1A and KGM43ER73U471KV both provide voltage rating upgrade to 3kV with improved ±10% tolerance. The KGM43ER73U471KV is designated within the KGM - HV series for high voltage applications.

Selection between substitutes depends on the required voltage margin for the application circuit. All three substitutes are electrically and mechanically compatible with the original part's footprint and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can 1812GC471KAT1A, 1812HC471KAT1A, or KGM43ER73U471KV be used as direct replacements for 1812CC471MATME?

A: Yes. All three parts maintain identical capacitance (470 pF), temperature coefficient (X7R), package type (1812/4532 Metric), physical dimensions (4.60mm x 3.20mm x 1.80mm max), and operating temperature range (-55°C ~ 125°C). The substitutes provide equal or higher voltage ratings and equal or tighter tolerance specifications.

Q: What is the difference between the three substitute parts?

A: The primary difference is voltage rating. 1812GC471KAT1A is rated at 2kV, while both 1812HC471KAT1A and KGM43ER73U471KV are rated at 3kV. All three offer improved ±10% tolerance compared to the original ±20% tolerance. KGM43ER73U471KV is part of the KGM - HV high voltage series.

Q: Are there any physical or mounting differences between the main part and substitutes?

A: No. All parts use identical 1812 (4532 Metric) surface mount package with matching physical dimensions of 4.60mm length, 3.20mm width, and 1.80mm maximum thickness. PCB footprints and reflow soldering profiles remain unchanged.

Q: Do all parts meet the same regulatory requirements?

A: Yes. The main part and all three substitutes are ROHS3 compliant, REACH unaffected, and classified as Active product status with MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute should be selected for maximum voltage margin?

A: Both 1812HC471KAT1A and KGM43ER73U471KV provide the highest voltage rating at 3kV. Selection between these two depends on series preference and availability, as both offer identical electrical and mechanical specifications.
