Engineering Selection Recommendations
Both parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment for current applications. The 1812AC273KAT1A substitute provides enhanced voltage margin (1000V versus 630V) and tighter tolerance specification (±10% versus ±20%), making it suitable for applications requiring higher reliability or stricter capacitance accuracy. Selection between the two parts depends on circuit voltage requirements and tolerance specifications. The substitute part's increased thickness (2.80mm versus 1.80mm) must be evaluated against available PCB assembly clearance. Both parts share identical footprint dimensions and thermal performance characteristics, supporting direct layout compatibility in most applications.
Frequently Asked Questions (FAQ)
Q: Can 1812AC273KAT1A replace 1812CC273MAT3A in all applications?
A: The substitute part maintains identical capacitance, temperature coefficient, and footprint dimensions. Compatibility depends on circuit voltage requirements and available PCB clearance. The substitute's 1000V rating exceeds the original 630V specification, and its ±10% tolerance is tighter than the original ±20%. The increased thickness (2.80mm versus 1.80mm) must be verified against board assembly constraints.
Q: What are the key differences between these parts?
A: The primary differences are voltage rating (1000V versus 630V), tolerance specification (±10% versus ±20%), and physical thickness (2.80mm versus 1.80mm). Capacitance value, temperature coefficient, operating temperature range, and footprint dimensions remain identical.
Q: Are both parts suitable for high voltage applications?
A: The 1812CC273MAT3A is rated for 630V operation. The 1812AC273KAT1A is rated for 1000V (1kV) operation, providing higher voltage capability. Selection depends on the specific circuit voltage requirements.
Q: What packaging formats are available?
A: The 1812CC273MAT3A is available in standard packaging. The 1812AC273KAT1A is supplied in Tape & Reel (TR) format, which is typical for high-volume manufacturing and automated assembly processes.
