Key Parameters

Substitute Part Grouping Explanation

The 1812SC562KAT1A qualifies as a direct substitute for the 1812SC562MAT3A based on the following critical parameters:

• Identical Capacitance: Both parts specify 5600 pF
• Identical Voltage Rating: Both rated at 1500V (1.5kV)
• Identical Temperature Coefficient: Both feature X7R characteristics
• Identical Operating Temperature Range: Both operate from -55°C to 125°C
• Identical Package: Both use 1812 (4532 Metric) surface-mount configuration
• Identical Physical Dimensions: Both measure 0.181" L × 0.126" W with 0.110" maximum thickness
• Identical Compliance: Both are ROHS3 compliant with MSL 1 rating

The primary distinction is the tolerance specification: the substitute part offers ±10% tolerance compared to the original ±20% tolerance, representing an upgrade in capacitance accuracy.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC562MAT3A and 1812SC562KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and identical electrical and mechanical specifications. The 1812SC562KAT1A provides improved tolerance performance at ±10% compared to the ±20% tolerance of the original part, making it suitable for applications requiring tighter capacitance control. Both parts maintain identical voltage ratings, temperature stability, and physical form factors, ensuring direct compatibility in circuit board layouts and assembly processes. Selection between these parts should be based on tolerance requirements specific to the application and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC562KAT1A replace the 1812SC562MAT3A in existing designs?

A: Yes. Both parts share identical capacitance (5600 pF), voltage rating (1500V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical package dimensions (1812/4532 Metric). The substitute part features improved tolerance (±10% versus ±20%), making it electrically and mechanically compatible.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The 1812SC562MAT3A has ±20% tolerance, while the 1812SC562KAT1A has ±10% tolerance. This means the substitute part maintains capacitance values within a tighter range around the nominal 5600 pF specification.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both parts are rated for 1500V (1.5kV) and feature high-voltage design characteristics. They maintain stable performance across the full operating temperature range of -55°C to 125°C.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL 1) ratings, indicating unlimited shelf life under normal storage conditions. Handling and storage procedures are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1812SC562MAT3A and 1812SC562KAT1A are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.
