Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC273MAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.181" L × 0.126" W and 0.110" maximum thickness
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1812AC273KAT1A qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and regulatory compliance. The primary distinction is the tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC273MAT3A and 1812AC273KAT1A are active products manufactured by KYOCERA AVX with full ROHS3 compliance and identical electrical and mechanical specifications. The 1812AC273KAT1A offers improved capacitance tolerance (±10% versus ±20%), which may be advantageous in applications requiring tighter capacitance control. Both parts maintain MSL 1 rating and are suitable for the same circuit applications. Selection between these parts should be based on tolerance requirements and packaging format availability (bulk versus tape & reel).

Frequently Asked Questions (FAQ)

Q: Can the 1812AC273KAT1A replace the 1812AC273MAT3A in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, temperature coefficient, package dimensions, and mounting type. The 1812AC273KAT1A provides tighter tolerance (±10% versus ±20%), making it suitable for direct substitution.
