1808AC153MAT3A Equivalent & Substitute Parts

Part Overview

The 1808AC153MAT3A is a 0.015 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with 884 units in stock. Substitute parts are identified when electrical specifications remain compatible and mechanical form factors are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC153MAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.015 µF (no deviation permitted)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R for consistent performance across the operating range
• Package / Case: Must be 1808 (4520 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match or be compatible with 4.60mm L × 2.00mm W footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1808AC153KAT1A qualifies as a direct substitute based on these parameters. The primary distinction is the tolerance specification, which is tighter (±10% versus ±20%), representing an upgrade in precision without affecting substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC153MAT3A and 1808AC153KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements:

• 1808AC153MAT3A (±20% tolerance): Suitable for general-purpose applications where standard tolerance is acceptable
• 1808AC153KAT1A (±10% tolerance): Suitable for applications requiring tighter capacitance tolerance control

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. The 1808AC153KAT1A offers higher precision without any trade-offs in voltage rating, temperature stability, or package form factor. Packaging format differs (1808AC153MAT3A uses standard packaging; 1808AC153KAT1A uses Tape & Reel), which may influence procurement logistics but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1808AC153KAT1A replace 1808AC153MAT3A in existing designs?

A: Yes. The 1808AC153KAT1A is a direct substitute. It maintains identical capacitance, voltage rating, temperature coefficient, package dimensions, and mounting type. The tighter tolerance (±10% versus ±20%) represents an upgrade in precision.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation from the nominal 0.015 µF value. The 1808AC153MAT3A allows ±20% deviation (0.012 µF to 0.018 µF), while the 1808AC153KAT1A allows ±10% deviation (0.0135 µF to 0.0165 µF). Applications requiring tighter capacitance control should use the ±10% part.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1808 (4520 Metric) package with identical dimensions: 4.60mm length, 2.00mm width, and 2.20mm maximum thickness. They are mechanically interchangeable on PCBs designed for the 1808 footprint.

Q: What is the difference in packaging?

A: The 1808AC153MAT3A uses standard packaging, while the 1808AC153KAT1A is supplied in Tape & Reel (TR) format. This affects handling and automated assembly processes but does not impact electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent from a regulatory and environmental compliance perspective.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications where standard tolerance is sufficient, either part is acceptable. For applications requiring tighter capacitance control, the 1808AC153KAT1A (±10%) is the appropriate choice.
