KYOCERA AVX 12063E334MAT2A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 12063E334MAT2A is a 0.33 µF ceramic capacitor rated for 25V with Z5U temperature coefficient, packaged in 1206 (3216 Metric) surface mount form factor. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of 10°C to 85°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when design requirements permit higher voltage ratings or when inventory availability necessitates alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution logic for the 12063E334MAT2A is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 0.33 µF (exact match required)
• Tolerance: ±20% (no deviation permitted)
• Temperature Coefficient: Z5U (thermal performance requirement)
• Package / Case: 1206 (3216 Metric) (PCB footprint compatibility)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: 10°C ~ 85°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: MSL 1 (handling requirement)

Allowable Variation:

• Voltage Rating: The substitute part 12065E334MAT2A is rated for 50V, which exceeds the 25V minimum requirement. Higher voltage ratings are acceptable as they provide additional design margin without affecting circuit functionality at lower operating voltages.

The identified substitute maintains all mandatory parameters while providing enhanced voltage headroom, making it suitable for applications where the original 25V rating is adequate but higher voltage margin is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (12063E334MAT2A): Use when the application circuit is designed specifically for 25V rated capacitors and inventory availability is sufficient. This part maintains the exact voltage specification for the intended design.

Substitute Part Selection (12065E334MAT2A): The 12065E334MAT2A is electrically and mechanically interchangeable with the primary part. The 50V voltage rating provides additional design margin while maintaining identical capacitance, tolerance, temperature coefficient, and physical dimensions. Both parts carry identical regulatory compliance (ROHS3, REACH Unaffected, EAR99) and moisture sensitivity ratings. Selection between these parts should be based on circuit voltage requirements, inventory availability, and supply chain considerations. The substitute part is suitable for direct replacement in applications where the original 25V specification is met by the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 12065E334MAT2A (50V) be used as a direct replacement for the 12063E334MAT2A (25V)?

A: Yes. The substitute part is electrically and mechanically compatible. Both parts have identical capacitance (0.33 µF), tolerance (±20%), temperature coefficient (Z5U), package dimensions (1206/3216 Metric), and operating temperature range (10°C ~ 85°C). The higher voltage rating of the substitute does not affect performance in circuits designed for 25V operation.

Q: Are there any physical differences between these parts?

A: No. Both parts share identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum thickness of 0.037" (0.94mm). They are mechanically interchangeable on the same PCB footprint.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8532.24.0020). Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Z5U temperature coefficient and other ceramic capacitor types?

A: Z5U specifies the capacitance change over the operating temperature range of 10°C to 85°C. Both parts maintain this specification, ensuring stable capacitance performance across the defined temperature range for general-purpose applications.

Q: Can I use the 25V part in a circuit designed for 50V?

A: No. The 25V part is rated for maximum 25V operation. Use only in circuits where the applied voltage does not exceed 25V. The 50V substitute provides higher voltage capability and should be used when higher voltage margin is required.

Q: What is the packaging difference between these parts?

A: The main part (12063E334MAT2A) packaging is not specified in standard format. The substitute part (12065E334MAT2A) is supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your assembly process before selection.
