1812AC153MAT1A Equivalent & Substitute Parts

Part Overview

The 1812AC153MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.015 µF capacitance with 1000V (1kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design optimization, or application-specific performance needs.

Substitute Part Grouping Explanation

The 1812SC153KAT1A qualifies as a direct substitute for the 1812AC153MAT1A based on the following substitution criteria:

Matching Parameters:

• Capacitance: 0.015 µF (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Package / Case: 1812 (4532 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Upgrade Characteristics:

• Voltage Rating: 1500V (1.5kV) versus 1000V (1kV) — the substitute provides higher voltage capability
• Tolerance: ±10% versus ±20% — the substitute offers tighter capacitance tolerance
• Physical Thickness: 2.80mm versus 2.20mm — the substitute has increased thickness due to higher voltage rating

The 1812SC153KAT1A maintains all critical electrical and mechanical compatibility requirements while providing enhanced voltage performance and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812AC153MAT1A and 1812SC153KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1812SC153KAT1A provides enhanced electrical performance through higher voltage rating (1500V versus 1000V) and improved tolerance specification (±10% versus ±20%), while maintaining identical physical footprint compatibility and thermal characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications where the original part is unavailable or where the enhanced voltage margin and tighter tolerance provide design benefits. Both parts are available in production quantities with unlimited moisture sensitivity level, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC153KAT1A replace the 1812AC153MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (0.015 µF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 1812 (4532 Metric) package footprint. The substitute provides higher voltage rating (1500V versus 1000V) and tighter tolerance (±10% versus ±20%), making it electrically and mechanically compatible for direct substitution.

Q: What is the physical difference between these parts?

A: The primary physical difference is thickness. The 1812AC153MAT1A has a maximum thickness of 0.087" (2.20mm), while the 1812SC153KAT1A has a maximum thickness of 0.110" (2.80mm). Both maintain identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm) dimensions. Verify PCB assembly clearance for the substitute part's increased thickness.

Q: Are there moisture sensitivity or handling differences?

A: No. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control or baking requirements during storage or assembly.

Q: What compliance certifications apply to both parts?

A: Both the 1812AC153MAT1A and 1812SC153KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why would I choose the substitute part over the original?

A: The 1812SC153KAT1A offers two advantages: higher voltage rating (1500V provides greater safety margin in high-voltage applications) and tighter capacitance tolerance (±10% versus ±20% for improved circuit performance consistency). Selection depends on application voltage requirements and tolerance specifications.
