Engineering Selection Recommendations

All substitute parts maintain Active product status and full compliance with RoHS3 and REACH regulations. Selection between the main part and substitutes is determined by application voltage requirements:

1812CC471MAT1A\SB is suitable for applications with maximum operating voltage of 630V and tolerance requirements of ±20%.

1812GC471KAT1A provides upgraded voltage rating of 2000V with improved tolerance of ±10%, maintaining identical physical form factor and environmental specifications.

1812HC471KAT1A and KGM43ER73U471KV both provide maximum voltage rating of 3000V with ±10% tolerance. The KGM43ER73U471KV is designated within the KGM - HV series. Both parts are electrically and mechanically interchangeable with the main part and each other.

All parts are manufactured by KYOCERA AVX with unlimited moisture sensitivity rating, eliminating bake-out requirements for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can 1812GC471KAT1A, 1812HC471KAT1A, or KGM43ER73U471KV be used as direct replacements for 1812CC471MAT1A\SB?

A: Yes. All substitute parts maintain identical capacitance (470 pF), temperature coefficient (X7R), package form factor (1812 / 4532 Metric), physical dimensions, and operating temperature range. The substitutes provide higher voltage ratings and improved tolerance specifications, making them suitable for applications where the original part is specified.

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

A: 1812GC471KAT1A is rated for 2000V with ±10% tolerance. Both 1812HC471KAT1A and KGM43ER73U471KV are rated for 3000V with ±10% tolerance. The KGM43ER73U471KV is part of the KGM - HV high-voltage series. All three are electrically and mechanically equivalent for applications requiring their respective voltage ratings.

Q: Are there any packaging differences between these parts?

A: The main part 1812CC471MAT1A\SB is supplied in standard packaging. All substitute parts are supplied in Tape & Reel (TR) format. Physical dimensions and mounting characteristics remain identical across all parts.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), eliminating moisture sensitivity handling requirements.

Q: Which substitute should be selected for a new design?

A: Selection depends on the maximum voltage requirement of the application. For 630V maximum, the original 1812CC471MAT1A\SB is appropriate. For applications requiring higher voltage margins, 1812GC471KAT1A (2000V) or 1812HC471KAT1A / KGM43ER73U471KV (3000V) provide enhanced reliability with identical form factor and compliance certifications.
