12101C563MAT2A Equivalent & Substitute Parts

Part Overview

The 12101C563MAT2A is a 0.056 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 100V with X7R temperature coefficient and ±20% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 1210 (3225 Metric) package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is active in production, ROHS3 compliant, and carries MSL 1 rating indicating unlimited moisture sensitivity protection. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required, particularly when tolerance specifications or inventory availability necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitution of the 12101C563MAT2A is permissible when the following electrical and mechanical parameters remain constant or improve:

• Capacitance value: 0.056 µF (exact match required)
• Voltage rating: 100V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: X7R (required for temperature stability)
• Package / Case: 1210 (3225 Metric) (exact match for PCB compatibility)
• Mounting type: Surface Mount, MLCC (required for assembly compatibility)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Moisture sensitivity: MSL 1 (minimum requirement)

The tolerance specification (±20% vs. ±10%) represents an upgrade path where tighter tolerance improves circuit performance without compromising compatibility. The substitute part 12101C563KAT2A meets all mandatory parameters with enhanced tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 12101C563MAT2A and 12101C563KAT2A are active production parts from KYOCERA AVX with identical regulatory compliance profiles. Selection between these parts depends on tolerance requirements:

The 12101C563MAT2A with ±20% tolerance is suitable for general purpose applications where capacitance variation within this range does not impact circuit performance.

The 12101C563KAT2A with ±10% tolerance provides tighter capacitance control and is appropriate for applications requiring improved accuracy. This substitute offers enhanced performance characteristics while maintaining full mechanical and electrical compatibility.

Both parts carry ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions. Selection should be based on circuit tolerance requirements and application specifications.

Frequently Asked Questions (FAQ)

Q: Can 12101C563KAT2A replace 12101C563MAT2A in existing designs?

A: Yes. The substitute part maintains identical capacitance value, voltage rating, temperature coefficient, package dimensions, and mounting type. The ±10% tolerance of the substitute represents an improvement over the ±20% tolerance of the original part, ensuring compatibility with all applications designed for the original specification.

Q: Are there physical differences between these parts?

A: No. Both parts share identical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm) and maximum thickness (0.037" / 0.94mm). They are both 1210 (3225 Metric) surface mount packages suitable for the same PCB footprints and assembly processes.

Q: What is the significance of the tolerance difference?

A: Tolerance specifies the allowable deviation from the nominal 0.056 µF capacitance value. The ±20% tolerance allows capacitance between 0.0448 µF and 0.0672 µF, while ±10% tolerance restricts the range to 0.0504 µF and 0.0616 µF. Tighter tolerance improves circuit predictability in applications sensitive to capacitance variation.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both 12101C563MAT2A and 12101C563KAT2A are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What does MSL 1 rating indicate?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited floor life, meaning the component requires no special moisture protection during storage or handling. Both parts carry this rating, eliminating moisture-related constraints in manufacturing and inventory management.
