Substitute Part Grouping Explanation

Substitute parts for the 1812CC471MAT3A\SB are qualified based on the following criteria:

Identical Parameters:

• Capacitance: 470 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.181" L x 0.126" W, 0.071" Max Thickness (exact match required)

Allowable Variations:

• Voltage - Rated: Higher voltage ratings are acceptable substitutes (2000V, 3000V)
• Tolerance: Tighter tolerance (±10%) is acceptable as an upgrade

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active status products from KYOCERA AVX with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the original 1812CC471MAT3A\SB specification.

1812GC471KAT1A provides a 2000V rated upgrade with ±10% tolerance improvement, suitable for applications requiring enhanced voltage margin while maintaining the 470 pF capacitance value.

1812HC471KAT1A and KGM43ER73U471KV both provide 3000V rated upgrades with ±10% tolerance improvement. The 1812HC471KAT1A is the standard AVX commercial grade part, while KGM43ER73U471KV belongs to the KGM - HV series for high-voltage applications. Both are electrically and mechanically interchangeable with identical package dimensions and thermal characteristics.

Selection between substitute parts depends on application voltage requirements and series preference. All parts maintain identical physical footprint and thermal performance across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can 1812GC471KAT1A, 1812HC471KAT1A, or KGM43ER73U471KV be used as direct replacements for 1812CC471MAT3A\SB?

A: Yes. All substitute parts maintain identical capacitance (470 pF), temperature coefficient (X7R), package dimensions (1812/4532 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (2000V or 3000V) and improved tolerance (±10%) are compatible upgrades for the original 630V specification.

Q: What is the difference between 1812HC471KAT1A and KGM43ER73U471KV?

A: Both parts have identical electrical specifications (470 pF, ±10%, 3000V, X7R) and physical dimensions. KGM43ER73U471KV is designated as part of the KGM - HV series for high-voltage applications. Selection depends on series preference and application requirements.

Q: Are there any package or footprint differences between the main part and substitutes?

A: No. All parts use the 1812 (4532 Metric) surface mount package with identical dimensions: 0.181" L x 0.126" W (4.60mm x 3.20mm) and 0.071" (1.80mm) maximum thickness. PCB layout and assembly processes remain unchanged.

Q: What does the tolerance improvement from ±20% to ±10% mean?

A: The substitute parts with ±10% tolerance provide tighter capacitance accuracy compared to the original ±20% specification. This means the actual capacitance value will be closer to the nominal 470 pF value, reducing circuit performance variation.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part 1812CC471MAT3A\SB and all substitute parts (1812GC471KAT1A, 1812HC471KAT1A, KGM43ER73U471KV) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
