KYOCERA AVX 12063E474MAT2A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 12063E474MAT2A is a 0.47 µF ceramic capacitor rated for 25V operation with Z5U temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1206 package format is designed for general-purpose applications requiring stable capacitance across the 10°C to 85°C operating temperature range. The part is actively manufactured and maintains ROHS3 compliance with MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions. Substitute parts are identified when design requirements permit higher voltage ratings or when inventory constraints necessitate alternative sourcing while maintaining functional equivalence.

Substitute Part Grouping Explanation

The identified substitute part maintains functional equivalence through strict parameter alignment:

Substitution Criteria:

• Capacitance value: 0.47 µF (exact match)
• Tolerance: ±20% (exact match)
• Temperature coefficient: Z5U (exact match)
• Package format: 1206 (3216 Metric) (exact match)
• Mounting type: Surface Mount, MLCC (exact match)
• Physical dimensions: Identical footprint and thickness
• Compliance: ROHS3 and REACH status maintained

Voltage Rating Consideration: The substitute part 12065E474MAT2A operates at 50V rated voltage, which exceeds the 25V specification of the primary part. This represents an upgrade path where the higher voltage rating provides additional design margin without altering any other electrical or mechanical characteristics. The substitute is directly interchangeable in applications where the 25V rating is sufficient, as the 50V-rated component will function identically at lower voltage stress levels.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory compliance for current and future applications. The primary part 12063E474MAT2A is suitable for designs operating at or below 25V with standard general-purpose capacitor requirements. The substitute 12065E474MAT2A provides identical electrical and mechanical performance with enhanced voltage margin, making it appropriate for applications where higher voltage headroom is beneficial or where supply chain availability favors the 50V variant. Selection between these parts should be based on circuit voltage requirements and component availability rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can 12065E474MAT2A replace 12063E474MAT2A in a 25V circuit? A: Yes. The 50V-rated substitute operates identically at 25V stress levels. The higher voltage rating does not affect capacitance, tolerance, temperature coefficient, or physical compatibility.

Q: Are the physical footprints identical? A: Yes. Both parts use the 1206 (3216 Metric) package with identical dimensions: 3.20mm length, 1.60mm width, and 0.94mm maximum thickness. PCB layout and assembly processes require no modification.

Q: Do both parts have the same moisture sensitivity requirements? A: Yes. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Identical moisture handling and storage protocols apply.

Q: What is the functional difference between these parts? A: The only difference is the voltage rating: 25V versus 50V. Capacitance, tolerance, temperature coefficient, and all mechanical specifications are identical.

Q: Are both parts ROHS3 compliant? A: Yes. Both 12063E474MAT2A and 12065E474MAT2A are ROHS3 compliant with REACH unaffected status, meeting current regulatory requirements.

Q: Which part should be selected for new designs? A: Selection depends on circuit voltage requirements. For 25V or lower applications, either part is acceptable. The 50V-rated substitute provides additional design margin if voltage headroom is desired.
