Substitute Part Grouping Explanation

Substitution of the 1812SC562MAT3A is permissible with the 1812SC562KAT1A based on the following critical parameters:

• Capacitance Value: Both parts maintain 5600 pF, ensuring identical functional performance in the circuit.
• Voltage Rating: Both parts are rated for 1500V (1.5kV), maintaining the same electrical stress capability.
• Temperature Coefficient: Both parts feature X7R characteristics, providing equivalent temperature stability across -55°C to 125°C.
• Package and Mounting: Both parts use the 1812 (4532 Metric) surface-mount package with identical physical dimensions and thickness, ensuring mechanical compatibility with PCB layouts.
• Compliance Standards: Both parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements.

The primary difference between these parts is the capacitance tolerance specification: the main part (1812SC562MAT3A) carries ±20% tolerance, while the substitute (1812SC562KAT1A) carries ±10% tolerance. The substitute offers tighter tolerance control, which may be advantageous for applications requiring more precise capacitance values.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC562MAT3A and 1812SC562KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following criteria:

• Tolerance Requirements: If the circuit design requires capacitance values within ±10% of the nominal 5600 pF specification, the 1812SC562KAT1A substitute is the appropriate choice. If ±20% tolerance is acceptable, either part is suitable.
• Packaging Format: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and inventory management practices.
• Availability: The substitute part has significantly higher inventory availability (11205 pieces versus 997 pieces), making it preferable for high-volume production runs or when supply continuity is a priority.

Both parts maintain identical electrical performance, thermal characteristics, and physical compatibility with the 1812 (4532 Metric) package footprint.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts have identical capacitance values (5600 pF), voltage ratings (1500V), temperature coefficients (X7R), and physical dimensions (1812 package). They are mechanically and electrically interchangeable. The substitute offers improved tolerance specification (±10% versus ±20%).

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

A: The 1812SC562MAT3A carries ±20% tolerance, meaning the actual capacitance can range from 4480 pF to 6720 pF. The 1812SC562KAT1A carries ±10% tolerance, with actual capacitance ranging from 5040 pF to 6160 pF. Applications requiring tighter capacitance control should specify the ±10% tolerance part.

Q: Are there any differences in thermal or electrical performance between these parts?

A: No. Both parts feature identical X7R temperature coefficients and operate across the same temperature range (-55°C to 125°C). Electrical performance characteristics are equivalent.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (1812SC562MAT3A) is suitable for manual assembly or small-volume production. Tape & Reel packaging (1812SC562KAT1A) is designed for automated pick-and-place assembly equipment and is standard for high-volume manufacturing.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance restrictions.
