1812SC562MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC562MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 5600 pF, rated for 1500V (1.5kV), and featuring X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable performance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained while accommodating different tolerance specifications or packaging configurations.

Substitute Part Grouping Explanation

Substitution of the 1812SC562MAT1A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must remain 5600 pF
• Voltage Rating: Must maintain 1500V (1.5kV) minimum
• Temperature Coefficient: Must be X7R for thermal stability
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.181" L × 0.126" W and 0.110" maximum thickness
• Operating Temperature Range: Must support -55°C to 125°C

The 1812SC562KAT1A qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±10% versus ±20%), making it suitable for applications where tighter capacitance tolerance is acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC562MAT1A and 1812SC562KAT1A are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The primary distinction between these parts is tolerance specification: the substitute part (1812SC562KAT1A) offers ±10% tolerance compared to the main part's ±20% tolerance. This tighter tolerance may be advantageous in applications where capacitance precision directly impacts circuit performance. Both parts maintain identical electrical ratings, thermal characteristics, and physical form factors, ensuring direct mechanical and electrical interchangeability within the specified operating parameters. Packaging format differs (standard versus Tape & Reel), which may influence procurement and assembly considerations but does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC562KAT1A directly replace the 1812SC562MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (5600 pF), voltage rating (1500V), temperature coefficient (X7R), package dimensions (1812/4532 Metric), and operating temperature range (-55°C to 125°C). The substitute part's improved tolerance (±10% versus ±20%) does not prevent direct substitution and may enhance circuit performance in tolerance-sensitive applications.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation from the nominal capacitance value. The 1812SC562MAT1A allows ±20% deviation (4480 pF to 6720 pF), while the 1812SC562KAT1A allows ±10% deviation (5040 pF to 6160 pF). Tighter tolerance (±10%) provides greater capacitance predictability and may be required for precision filtering, timing, or resonant circuit applications.

Q: Are there packaging differences between these parts?

A: The main part uses standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical performance or physical compatibility on the PCB.

Q: Do both parts meet current compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain active production status.

Q: What is the moisture sensitivity level, and does it differ between these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
