1825AC333MAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1825AC333MAT1A\SB is a 0.033 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC333MAT1A\SB is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 0.033 µF (no tolerance variation in nominal value)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and PCB footprint compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain ROHS3 and REACH compliance status

The substitute part 1825AC333KAT1A meets all substitution criteria. The primary difference is capacitance tolerance: the main part specifies ±20% tolerance, while the substitute offers tighter ±10% tolerance. This represents an upgrade in precision without affecting electrical compatibility or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC333MAT1A\SB and 1825AC333KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements and packaging format:

• 1825AC333MAT1A\SB: Select when ±20% capacitance tolerance is acceptable and standard packaging is required.
• 1825AC333KAT1A: Select when tighter ±10% capacitance tolerance is required for improved circuit performance or when Tape & Reel packaging format is specified for automated assembly processes.

Both parts are electrically and mechanically interchangeable within the same PCB design. No circuit modifications or re-qualification is necessary when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can 1825AC333KAT1A be used as a direct replacement for 1825AC333MAT1A\SB?

A: Yes. Both parts share identical capacitance value (0.033 µF), voltage rating (1000V), temperature coefficient (X7R), package (1825), and operating temperature range (-55°C to 125°C). The substitute offers improved tolerance (±10% vs ±20%), making it a compatible upgrade.

Q: What is the difference between the two parts?

A: The primary difference is capacitance tolerance. The 1825AC333MAT1A\SB has ±20% tolerance, while the 1825AC333KAT1A has ±10% tolerance. Additionally, packaging format differs: the main part uses standard packaging, while the substitute is supplied in Tape & Reel format.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts use identical X7R dielectric material, operate across the same temperature range (-55°C to 125°C), and are rated for 1000V. Thermal and electrical performance characteristics are equivalent.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided circuit design tolerances accommodate the ±20% specification of the 1825AC333MAT1A\SB. If tighter tolerance control is required, use only the 1825AC333KAT1A.

Q: Are both parts RoHS compliant?

A: Yes. Both 1825AC333MAT1A\SB and 1825AC333KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the part has unlimited shelf life and requires no special moisture control during storage or handling, simplifying inventory management and assembly processes.
