The identified substitute maintains all electrical and mechanical specifications within the allowed parameter set. Substitution is valid only when all parameters listed above are identical between the main part and the alternative component.

Parameter Comparison

Engineering Selection Recommendations

Both the 08052C821KAT4A and 08052C821KAT2A are active production components from KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements. Both components meet ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance. The difference in packaging designation (KAT4A versus KAT2A) reflects internal manufacturer coding and does not affect functional equivalence or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can 08052C821KAT2A be used as a direct replacement for 08052C821KAT4A?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (820 pF), tolerance (±10%), voltage rating (200V), temperature coefficient (X7R), and 0805 package specifications. They are interchangeable in circuit design and PCB layout.

Q: What does the difference between KAT4A and KAT2A designations mean?

A: These designations represent internal manufacturer packaging or tape reel configurations. The electrical and mechanical performance of the capacitor itself remains identical. The suffix does not indicate a functional difference in the component.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. They meet the same regulatory requirements for industrial and commercial applications.

Q: Can these capacitors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C with X7R temperature coefficient, which provides stable capacitance across this range. X7R dielectric materials are suitable for general purpose applications requiring temperature stability.

Q: What is the significance of the 0805 (2012 Metric) package designation?

A: The 0805 package is a standard surface mount MLCC footprint measuring 0.079" x 0.049" (2.01mm x 1.25mm). Both substitute parts use this identical package, ensuring compatibility with existing PCB designs and assembly processes without layout modifications.
