Substitute Part Grouping Explanation

Substitution for the 1825AC333MAT3A\SB is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.033 µF (no deviation)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable capacitance across temperature range)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain RoHS3 compliance and MSL 1 rating

The substitute part 1825AC333KAT1A meets all substitution criteria with identical electrical specifications except for improved tolerance (±10% versus ±20%), which represents a performance upgrade rather than a compromise.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC333MAT3A\SB and 1825AC333KAT1A are Active products from KYOCERA AVX with full RoHS3 compliance and REACH unaffected status. The primary distinction is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations.

The 1825AC333KAT1A represents a direct functional upgrade due to its ±10% tolerance specification compared to the ±20% tolerance of the main part. This tighter tolerance provides improved capacitance accuracy without any electrical or mechanical compromise. Both parts are suitable for general-purpose high-voltage applications and maintain identical thermal stability through the X7R temperature coefficient specification.

Selection between these parts should be based on packaging requirements (bulk versus tape & reel) and tolerance specifications needed for the application. The substitute part is recommended where tighter capacitance tolerance is beneficial and tape & reel packaging is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 1825AC333KAT1A be used as a direct replacement for 1825AC333MAT3A\SB?

A: Yes. Both parts share identical capacitance (0.033 µF), voltage rating (1000V), temperature coefficient (X7R), package dimensions (1825/4564 Metric), and operating temperature range (-55°C to 125°C). The substitute features improved tolerance (±10% versus ±20%), which is a performance upgrade. The primary difference is packaging format: tape & reel versus standard packaging.

Q: What does the ±10% tolerance improvement mean for circuit performance?

A: Tolerance defines the acceptable deviation from the nominal 0.033 µF capacitance value. The ±10% tolerance of 1825AC333KAT1A restricts capacitance variation to 0.0297 µF to 0.0363 µF, while the ±20% tolerance of 1825AC333MAT3A\SB allows 0.0264 µF to 0.0396 µF. Tighter tolerance provides more predictable circuit behavior and is advantageous in precision applications.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both parts are rated for 1000V (1kV) operation and feature high-voltage design characteristics. They are suitable for general-purpose high-voltage applications within the specified operating temperature range.

Q: What is the significance of X7R temperature coefficient?

A: X7R temperature coefficient ensures that capacitance remains stable across the operating temperature range of -55°C to 125°C. This characteristic is critical for applications requiring consistent performance across varying environmental conditions.

Q: Does packaging format affect electrical performance?

A: No. Tape & reel (TR) packaging and standard packaging contain identical components. Packaging format affects only handling, storage, and assembly process compatibility. Tape & reel format is standard for automated surface-mount assembly operations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1825AC333MAT3A\SB and 1825AC333KAT1A maintain full RoHS3 compliance and are REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.
